Did what you study in college prepare you for this career choice? How did you figure out this career was something you were interested in?

The Big Build: Artemis I Stacks Up

Our Space Launch System (SLS) rocket is coming together at the agency’s Kennedy Space Center in Florida this summer. Our mighty SLS rocket is set to power the Artemis I mission to send our Orion spacecraft around the Moon. But, before it heads to the Moon, NASA puts it together right here on Earth.

Read on for more on how our Moon rocket for Artemis I will come together this summer:

Get the Base

How do crews assemble a rocket and spacecraft as tall as a skyscraper? The process all starts inside the iconic Vehicle Assembly Building at Kennedy with the mobile launcher. Recognized as a Florida Space Coast landmark, the Vehicle Assembly Building, or VAB, houses special cranes, lifts, and equipment to move and connect the spaceflight hardware together. Orion and all five of the major parts of the Artemis I rocket are already at Kennedy in preparation for launch. Inside the VAB, teams carefully stack and connect the elements to the mobile launcher, which serves as a platform for assembly and, later, for fueling and launching the rocket.

Start with the boosters

Because they carry the entire weight of the rocket and spacecraft, the twin solid rocket boosters for our SLS rocket are the first elements to be stacked on the mobile launcher inside the VAB. Crews with NASA’s Exploration Ground Systems and contractor Jacobs team completed stacking the boosters in March. Each taller than the Statue of Liberty and adorned with the iconic NASA “worm” logo, the five-segment boosters flank either side of the rocket’s core stage and upper stage. At launch, each booster produces more than 3.6 million pounds of thrust in just two minutes to quickly lift the rocket and spacecraft off the pad and to space.

Bring in the core stage

In between the twin solid rocket boosters is the core stage. The stage has two huge liquid propellant tanks, computers that control the rocket’s flight, and four RS-25 engines. Weighing more than 188,000 pounds without fuel and standing 212 feet, the core stage is the largest element of the SLS rocket. To place the core stage in between the two boosters, teams will use a heavy-lift crane to raise and lower the stage into place on the mobile launcher.

On launch day, the core stage’s RS-25 engines produce more than 2 million pounds of thrust and ignite just before the boosters. Together, the boosters and engines produce 8.8 million pounds of thrust to send the SLS and Orion into orbit.

Add the Launch Vehicle Stage Adapter

Once the boosters and core stage are secured, teams add the launch vehicle stage adapter, or LVSA, to the stack. The LVSA is a cone-shaped element that connects the rocket’s core stage and Interim Cryogenic Propulsion Stage (ICPS), or upper stage. The roughly 30-foot LVSA houses and protects the RL10 engine that powers the ICPS. Once teams bolt the LVSA into place on top of the rocket, the diameter of SLS will officially change from a wide base to a more narrow point — much like a change in the shape of a pencil from eraser to point.

Lower the Interim Cryogenic Propulsion Stage into place

Next in the stacking line-up is the Interim Cryogenic Propulsion Stage or ICPS. Like the LVSA, crews will lift and bolt the ICPS into place. To help power our deep space missions and goals, our SLS rocket delivers propulsion in phases. At liftoff, the core stage and solid rocket boosters will propel Artemis I off the launch pad. Once in orbit, the ICPS and its single RL10 engine will provide nearly 25,000 pounds of thrust to send our Orion spacecraft on a precise trajectory to the Moon.

Nearly there with the Orion stage adapter

When the Orion stage adapter crowns the top of the ICPS, you’ll know we’re nearly complete with stacking SLS rocket for Artemis I. The Orion Stage Adapter is more than just a connection point. At five feet in height, the Orion stage adapter may be small, but it holds and carries several small satellites called CubeSats. After Orion separates from the SLS rocket and heads to the Moon, these shoebox-sized payloads are released into space for their own missions to conduct science and technology research vital to deep space exploration. Compared to the rest of the rocket and spacecraft, the Orion stage adapter is the smallest SLS component that’s stacked for Artemis I.

Top it off

Finally, our Orion spacecraft will be placed on top of our Moon rocket inside the VAB. The final piece will be easy to spot as teams recently added the bright red NASA “worm” logotype to the outside of the spacecraft. The Orion spacecraft is much more than just a capsule built to carry crew. It has a launch abort system, which will carry the crew to safety in case of an emergency, and a service module developed by the European Space Agency that will power and propel the spacecraft during its three-week mission. On the uncrewed Artemis I mission, Orion will check out the spacecraft’s critical systems, including navigation, communications systems, and the heat shield needed to support astronauts who will fly on Artemis II and beyond.

Ready for launch!

The path to the pad requires many steps and check lists. Before Artemis I rolls to the launch pad, teams will finalize outfitting and other important assembly work inside the VAB. Once assembled, the integrated SLS rocket and Orion will undergo several final tests and checkouts in the VAB and on the launch pad before it’s readied for launch.

The Artemis I mission is the first in a series of increasingly complex missions that will pave the way for landing the first woman and the first person of color on the Moon. The Space Launch System is the only rocket that can send NASA astronauts aboard NASA’s Orion spacecraft and supplies to the Moon in a single mission.

What Would These Astronauts Put in Their #NASAMoonKit?

NASA is hard at work to land the first woman and the next man on the Moon, and we want to know: what would you pack for a trip to the Moon?   

We will be soon conducting our last in a series of Green Run tests for the core stage of our Space Launch System (SLS) — the most powerful rocket ever built.

The series of tests is designed to gradually bring the rocket stage and all its systems to life for the first time — ensuring that it’s ready for missions to the Moon through the Artemis program.  

To mark this critical time in the history of American spaceflight, we’ve been asking people like you — what would you take with you on a trip to the Moon? Social media users have been regaling us with their images, videos, and illustrations with the hashtag #NASAMoonKit!

Looking for a little inspiration? We asked some of our astronauts and NASA leaders the same question:

1. NASA Astronaut Chris Cassidy

NASA astronaut Chris Cassidy recently took this photo from the International Space Station and posted it to his Twitter account with this caption:

“If I was on the next mission to the Moon, I would have to bring this tiny spaceman with me! He’s flown with me on all of my missions and was in my uniform pocket for all the SEAL missions I have been a part of. Kind of like a good luck charm.”

2. European Space Agency Astronaut Tim Peake

European Space Agency astronaut Tim Peake asked his two sons what they would take with them to the Moon. This is what they decided on!

3. NASA Astronaut Scott Tingle

Based on previous missions to space, NASA astronaut Scott Tingle would put a can of LiOH, or Lithium Hydroxide, into his #NASAMoonKit. 

A LiOH can pulls carbon dioxide out of the air — very important when you're in a closed environment for a long time! Apollo 13 enthusiasts will remember that the astronauts had to turn off their environmental system to preserve power. To keep the air safe, they used LiOH cans from another part of the vehicle, but the cans were round and the fitting was square. Today we have interoperability standards for space systems, so no more square pegs in round holes!

4. NASA Astronaut Drew Morgan

NASA astronaut Drew Morgan received some feedback from his youngest daughter when she was in kindergarten about she would put into her #NASAMoonKit.

5. Head of Human Spaceflight Kathy Lueders

Although Kathy Lueders is not an astronaut, she is the head of human spaceflight at NASA! Her #NASAMoonKit includes activities to keep her entertained as well as her favorite pillow.

6. NASA Astronaut Kenneth Bowersox

NASA astronaut Kenneth Bowersox knows from his past space shuttle experience what the “perfect space food” is — peanut butter. He would also put a hooded sweatshirt in his #NASAMoonKit, for those long, cold nights on the way to the Moon.

7. NASA Astronaut Michael Collins

NASA astronaut Michael Collins has actually made a real-life #NASAMoonKit — when he flew to the Moon on the Apollo 11 mission! But for this time around, he tweeted that would like to bring coffee like he did the first time — but add on a good book.

Get Ready To Launch America!

A new era of human spaceflight is about to begin. American astronauts will once again launch on an American rocket from American soil to the International Space Station as part of our Commercial Crew Program! NASA astronauts Bob Behnken and Doug Hurley will fly on SpaceX’s Crew Dragon spacecraft, lifting off on a Falcon 9 rocket at 4:32 p.m. EDT May 27, from Kennedy Space Center in Florida, for an extended stay at the space station for the Demo-2 mission. 

As the final flight test for SpaceX, this mission will validate the company’s crew transportation system, including the launch pad, rocket, spacecraft and operational capabilities. This also will be the first time NASA astronauts will test the spacecraft systems in orbit.

Behnken and Hurley were among the first astronauts to begin working and training on SpaceX’s next-generation human space vehicle and were selected for their extensive test pilot and flight experience, including several missions on the space shuttle.

Behnken will be the joint operations commander for the mission, responsible for activities such as rendezvous, docking and undocking, as well as Demo-2 activities while the spacecraft is docked to the space station.

Hurley will be the spacecraft commander for Demo-2, responsible for activities such as launch, landing and recovery.

Lifting off from Launch Pad 39A atop a specially instrumented Falcon 9 rocket, Crew Dragon will accelerate its two passengers to approximately 17,000 mph and put it on an intercept course with the International Space Station. In about 24 hours, Crew Dragon will be in position to rendezvous and dock with the space station. The spacecraft is designed to do this autonomously but astronauts aboard the spacecraft and the station will be diligently monitoring approach and docking and can take control of the spacecraft if necessary.

The Demo-2 mission will be the final major step before our Commercial Crew Program certifies Crew Dragon for operational, long-duration missions to the space station. This certification and regular operation of Crew Dragon will enable NASA to continue the important research and technology investigations taking place onboard the station, which benefits people on Earth and lays the groundwork for future exploration of the Moon and Mars starting with the agency’s Artemis program, which will land the first woman and the next man on the lunar surface in 2024.

You’ve Heard “Houston, we’ve had a problem,” But Do You Know The Mission It’s From?

It’s the 50th anniversary of the Apollo 13 mission! NASA’s “successful failure,”Apollo 13 was to be the third lunar landing attempt, but the mission was aborted mid-flight after the rupture of a service module oxygen tank. The crew never landed on the moon, but due to the dedication and ingenuity of Mission Control, made it back to Earth safely. We’ve put some of the most important numbers of the Apollo 13 mission in perspective. Check it out!

Spaceships Don’t Go to the Moon Until They’ve Gone Through Ohio

From the South, to the Midwest, to infinity and beyond. The Orion spacecraft for Artemis I has several stops to make before heading out into the expanse, and it can’t go to the Moon until it stops in Ohio. It landed at the Mansfield Lahm Regional Airport on Nov. 24, and then it was transferred to Plum Brook Station where it will undergo a series of environmental tests over the next four months to make sure it’s ready for space. Here are the highlights of its journey so far.

It’s a bird? It’s a whale? It’s the Super Guppy!

The 40-degree-and-extremely-windy weather couldn’t stop the massive crowd at Mansfield from waiting hours to see the Super Guppy land. Families huddled together as they waited, some decked out in NASA gear, including one astronaut costume complete with a helmet. Despite the delays, about 1,500 people held out to watch the bulbous airplane touch down.

Buckle up. It’s time for an extremely safe ride.

After Orion safely made it to Ohio, the next step was transporting it 41 miles to Plum Brook Station. It was loaded onto a massive truck to make the trip, and the drive lasted several hours as it slowly maneuvered the rural route to the facility. The 130-foot, 38-wheel truck hit a peak speed of about 20 miles per hour. It was the largest load ever driven through the state, and more than 700 utility lines were raised or moved in preparation to let the vehicle pass.

Calling us clean freaks would be an understatement.

Any person who even thinks about breathing near Orion has to be suited up. We’re talking “bunny” suit, shoe covers, beard covers, hoods, latex gloves – the works. One of our top priorities is keeping Orion clean during testing to prevent contaminants from sticking to the vehicle’s surface. These substances could cause issues for the capsule during testing and, more importantly, later during its flight around the Moon.

And liftoff of Orion… via crane.

On the ceiling of the Space Environments Complex at Plum Brook Station is a colossal crane used to move large pieces of space hardware into position for testing. It’s an important tool during pretest work, as it is used to lift Orion from the “verticator”—the name we use for the massive contraption used to rotate the vehicle from its laying down position into an upright testing orientation. After liftoff from the verticator, technicians then used the crane to install the spacecraft inside the Heat Flux System for testing.

It’s really not tin foil.

Although it looks like tin foil, the metallic material wrapped around Orion and the Heat Flux System—the bird cage-looking hardware encapsulating the spacecraft—is a material called Mylar. It’s used as a thermal barrier to help control which areas of the spacecraft get heated or cooled during testing. This helps our team avoid wasting energy heating and cooling spots unnecessarily.

Bake at 300° for 63 days.

It took a little over a week to prep Orion for its thermal test in the vacuum chamber. Now begins the 63-day process of heating and cooling (ranging from -250° to 300° Fahrenheit) the capsule to ensure it’s ready to withstand the journey around the Moon and back.

The Artemis Story: Where We Are Now and Where We’re Going

Using a sustainable architecture and sophisticated hardware unlike any other, the first woman and the next man will set foot on the surface of the Moon by 2024. Artemis I, the first mission of our powerful Space Launch System (SLS) rocket and Orion spacecraft, is an important step in reaching that goal.

As we close out 2019 and look forward to 2020, here’s where we stand in the Artemis story — and what to expect in 2020. 

Cranking Up The Heat on Orion

The Artemis I Orion spacecraft arrived at our Plum Brook Station in Sandusky, Ohio, on Tuesday, Nov. 26 for in-space environmental testing in preparation for Artemis I.

This four-month test campaign will subject the spacecraft, consisting of its crew module and European-built service module, to the vacuum, extreme temperatures (ranging from -250° to 300° F) and electromagnetic environment it will experience during the three-week journey around the Moon and back. The goal of testing is to confirm the spacecraft’s components and systems work properly under in-space conditions, while gathering data to ensure the spacecraft is fit for all subsequent Artemis missions to the Moon and beyond. This is the final critical step before the spacecraft is ready to be joined with the Space Launch System rocket for this first test flight in 2020!

Bringing Everyone Together

On Dec. 9, we welcomed members of the public to our Michoud Assembly Facility in New Orleans for #Artemis Day and to get an up-close look at the hardware that will help power our Artemis missions. The 43-acre facility has more than enough room for guests and the Artemis I, II, and III rocket hardware! NASA Administrator Jim Bridenstine formally unveiled the fully assembled core stage of our SLS rocket for the first Artemis mission to the Moon, then guests toured of the facility to see flight hardware for Artemis II and III. The full-day event — complete with two panel discussions and an exhibit hall — marked a milestone moment as we prepare for an exciting next phase in 2020.

Rolling On and Moving Out

Once engineers and technicians at Michoud complete functional testing on the Artemis I core stage, it will be rolled out of the Michoud factory and loaded onto our Pegasus barge for a very special delivery indeed. About this time last year, our Pegasus barge crew was delivering a test version of the liquid hydrogen tank from Michoud to NASA’s Marshall Space Flight Center in Huntsville for structural testing. This season, the Pegasus team will be transporting a much larger piece of hardware — the entire core stage — on a slightly shorter journey to the agency’s nearby Stennis Space Center near Bay St. Louis, Mississippi.

Special Delivery

Why Stennis, you ask? The giant core stage will be locked and loaded into the B2 Test Stand there for the landmark Green Run test series. During the test series, the entire stage, including its extensive avionics and flight software systems, will be tested in full. The series will culminate with a hot fire of all four RS-25 engines and will certify the complex stage “go for launch.” The next time the core stage and its four engines fire as one will be on the launchpad at NASA’s Kennedy Space Center in Florida.

Already Working on Artemis II

As Orion and SLS make progress toward the pad for Artemis I, employees at NASA centers and large and small companies across America are hard at work assembling and manufacturing flight hardware for Artemis II and beyond.  The second mission of SLS and Orion will be a test flight with astronauts aboard that will go around the Moon before returning home. Our work today will pave the way for a new generation of moonwalkers and Artemis explorers.

Women in Exploration: From Human Computers to All-Woman Spacewalks

Since the 19th century, women have been making strides in areas like coding, computing, programming and space travel, despite the challenges they have faced. Sally Ride joined NASA in 1983 and five years later she became the first female American astronaut. Ride's accomplishments paved the way for the dozens of other women who became astronauts, and the hundreds of thousands more who pursued careers in science and technology. Just last week, we celebrated our very first #AllWomanSpacewalk with astronauts Christina Koch and Jessica Meir.

Here are just a couple of examples of pioneers who brought us to where we are today:

The Conquest of the Sound Barrier

Pearl Young was hired in 1922 by the National Advisory Committee for Aeronautics (NACA), NASA’s predecessor organization, to work at its Langley site in support in instrumentation, as one of the first women hired by the new agency. Women were also involved with the NACA at the Muroc site in California (now Armstrong Flight Research Center) to support flight research on advanced, high-speed aircraft. These women worked on the X-1 project, which became the first airplane to fly faster than the speed of sound. 

Young was the first woman hired as a technical employee and the second female physicist working for the federal government.

The Human Computers of Langley

The NACA hired five women in 1935 to form its first “computer pool”, because they were hardworking, “meticulous” and inexpensive. After the United States entered World War II, the NACA began actively recruiting similar types to meet the workload. These women did all the mathematical calculations – by hand – that desktop and mainframe computers do today.

Computers played a role in major projects ranging from World War II aircraft testing to transonic and supersonic flight research and the early space program. Women working as computers at Langley found that the job offered both challenges and opportunities. With limited options for promotion, computers had to prove that women could successfully do the work and then seek out their own opportunities for advancement.

Revolutionizing X-ray Astronomy

Marjorie Townsend was blazing trails from a very young age. She started college at age 15 and became the first woman to earn an engineering degree from the George Washington University when she graduated in 1951. At NASA, she became the first female spacecraft project manager, overseeing the development and 1970 launch of the UHURU satellite. The first satellite dedicated to x-ray astronomy, UHURU detected, surveyed and mapped celestial X-ray sources and gamma-ray emissions.

Women of Apollo

NASA’s mission to land a human on the Moon for the very first time took hundreds of thousands workers. These are some of the stories of the women who made our recent #Apollo50th anniversary possible:

• Margaret Hamilton led a NASA team of software engineers at the Massachusetts Institute of Technology and helped develop the flight software for NASA’s Apollo missions. She also coined the term “software engineering.” Her team’s groundbreaking work was perfect; there were no software glitches or bugs during the crewed Apollo missions. 

• JoAnn Morgan was the only woman working in Mission Control when the Apollo 11 mission launched. She later accomplished many NASA “firsts” for women:  NASA winner of a Sloan Fellowship, division chief, senior executive at the Kennedy Space Center and director of Safety and Mission Assurance at the agency.

• Judy Sullivan, was the first female engineer in the agency’s Spacecraft Operations organization, was the lead engineer for health and safety for Apollo 11, and the only woman helping Neil Armstrong suit up for flight.

Hidden Figures

Author Margot Lee Shetterly’s book – and subsequent movie – Hidden Figures, highlighted African-American women who provided instrumental support to the Apollo program, all behind the scenes.

• An alumna of the Langley computing pool, Mary Jackson was hired as the agency’s first African-American female engineer in 1958. She specialized in boundary layer effects on aerospace vehicles at supersonic speeds. 

• An extraordinarily gifted student, Katherine Johnson skipped several grades and attended high school at age 13 on the campus of a historically black college. Johnson calculated trajectories, launch windows and emergency backup return paths for many flights, including Apollo 11.

• Christine Darden served as a “computress” for eight years until she approached her supervisor to ask why men, with the same educational background as her (a master of science in applied mathematics), were being hired as engineers. Impressed by her skills, her supervisor transferred her to the engineering section, where she was one of few female aerospace engineers at NASA Langley during that time.

Lovelace’s Woman in Space Program

Geraldyn “Jerrie” Cobb was the among dozens of women recruited in 1960 by Dr. William Randolph "Randy" Lovelace II to undergo the same physical testing regimen used to help select NASA’s first astronauts as part of his privately funded Woman in Space Program.

Ultimately, thirteen women passed the same physical examinations that the Lovelace Foundation had developed for NASA’s astronaut selection process. They were: Jerrie Cobb, Myrtle "K" Cagle, Jan Dietrich, Marion Dietrich, Wally Funk, Jean Hixson, Irene Leverton, Sarah Gorelick, Jane B. Hart, Rhea Hurrle, Jerri Sloan, Gene Nora Stumbough, and Bernice Trimble Steadman. Though they were never officially affiliated with NASA, the media gave these women the unofficial nicknames “Fellow Lady Astronaut Trainees” and the “Mercury Thirteen.”

The First Woman on the Moon

The early space program inspired a generation of scientists and engineers. Now, as we embark on our Artemis program to return humanity to the lunar surface by 2024, we have the opportunity to inspire a whole new generation. The prospect of sending the first woman to the Moon is an opportunity to influence the next age of women explorers and achievers.

What is your advice to someone who wants to follow the same steps you take?

We’re Turning up the Heat on the Artemis I Spacecraft 🔥

The Orion spacecraft for Artemis I is headed to Ohio, where a team of engineers and technicians at our Plum Brook Station stand ready to test it under extreme simulated in-space conditions, like temperatures up to 300°F, at the world’s premier space environments test facility.

Why so much heat? What’s the point of the test? We’ve got answers to all your burning questions.

Here, in the midst of a quiet, rural landscape in Sandusky, Ohio, is our Space Environments Complex, home of the world’s most powerful space simulation facilities. The complex houses a massive thermal vacuum chamber (100-foot diameter and 122-foot tall), which allows us to “test like we fly” and accurately simulate space flight conditions while still on the ground.

Orion’s upcoming tests here are important because they will confirm the spacecraft’s systems perform as designed, while ensuring safe operation for the crew during future Artemis missions.

Tests will be completed in two phases, beginning with a thermal vacuum test, lasting approximately 60 days, inside the vacuum chamber to stress-test and check spacecraft systems while powered on.

During this phase, the spacecraft will be subjected to extreme temperatures, ranging from -250°F to 300 °F, to replicate flying in-and-out of sunlight and shadow in space.

To simulate the extreme temperatures of space, a specially-designed system, called the Heat Flux, will surround Orion like a cage and heat specific parts of the spacecraft during the test. This image shows the Heat Flux installed inside the vacuum chamber. The spacecraft will also be surrounded on all sides by a cryogenic-shroud, which provides the cold background temperatures of space.

We’ll also perform electromagnetic interference tests. Sounds complicated, but, think of it this way. Every electronic component gives off some type of electromagnetic field, which can affect the performance of other electronics nearby—this is why you’re asked to turn off your cellphone on an airplane. This testing will ensure the spacecraft’s electronics work properly when operated at the same time and won’t be affected by outside sources.

What’s next? After the testing, we’ll send Orion back to our Kennedy Space Center in Florida, where it will be installed atop the powerful Space Launch System rocket in preparation for their first integrated test flight, called Artemis I, which is targeted for 2020.

Throwback Thursday: Apollo 11 FAQ Edition

With the help of the NASA History Office, we’ve identified some of the most frequently asked questions surrounding the first time humans walked on the surface of another world. Read on and click here to check out our previous Apollo FAQs. 

How many moon rocks did the Apollo crews bring back? What did we learn?

The six crews that landed on the Moon brought back 842 pounds (382 kilograms) of rocks, sand and dust from the lunar surface. Each time, they were transferred to Johnson Space Center’s Lunar Receiving Laboratory, a building that also housed the astronauts during their three weeks of quarantine. Today the building now houses other science divisions, but the lunar samples are preserved in the Lunar Sample Receiving Laboratory.

Built in 1979, the laboratory is the chief repository of the Apollo samples.

From these pieces of the Moon we learned that its chemical makeup is similar to that of Earth’s, with some differences. Studying the samples has yielded clues to the origins of the solar system. In March of 2019, we announced that three cases of pristine Moon samples will be unsealed for the first time in 50 years so that we can take advantage of the improved technology that exists today! 

Did you know you might not have to travel far to see a piece of the Moon up close? Visit our Find a Moon Rock page to find out where you can visit a piece of the Moon.

What did Apollo astronauts eat on their way to the Moon?

Astronaut food has come a long way since the days of Project Mercury, our first human spaceflight program that ran from 1958-1963. Back then, astronauts “enjoyed” food in cube form or squeezed out of tubes. Early astronaut food menus were designed less for flavor and more for nutritional value, but that eventually shifted as technology evolved. Astronauts today can enjoy whole foods like apples, pizza and even tacos. 

Apollo crews were the first to have hot water, making it easier to rehydrate their foods and improve its taste. They were also the first to use a “spoon bowl,” a plastic container that was somewhat like eating out of a Ziploc bag with a spoon. Here’s an example of a day’s menu for a voyage to the Moon:

Breakfast: bacon squares, strawberry cubes and an orange drink.

Lunch: beef and potatoes, applesauce and a brownie.

Dinner: salmon salad, chicken and rice, sugar cookie cubes and a pineapple grapefruit drink.

What did Michael Collins do while he orbited the Moon, alone in the Command Module?

As Neil Armstrong and Buzz Aldrin worked on the lunar surface, Command Module pilot Michael Collins orbited the Moon, alone, for the next 21.5 hours. On board he ran systems checks, made surface observations and communicated with Mission Control when there wasn’t a communications blackout. Blackouts happened every time Collins went behind the Moon. In 2009, Collins wrote this in response to a flurry of media questions about the 40th anniversary of the mission:

Q. Circling the lonely Moon by yourself, the loneliest person in the universe, weren't you lonely? A. No. Far from feeling lonely or abandoned, I feel very much a part of what is taking place on the lunar surface. I know that I would be a liar or a fool if I said that I have the best of the three Apollo 11 seats, but I can say with truth and equanimity that I am perfectly satisfied with the one I have. This venture has been structured for three men, and I consider my third to be as necessary as either of the other two.”

What will Artemis astronauts bring back when they land on the Moon?

Artemis missions to the Moon will mark humanity’s first permanent presence on another world. The first woman and the next man to explore the lunar surface will land where nobody has ever attempted to land before -- on the Moon’s south pole where there are billions of tons of water ice that can be used for oxygen and fuel. We don’t know yet what astronauts will bring back from this unexplored territory, but we do know that they will return with hope and inspiration for the next generation of explorers: the Artemis generation.

Demo-1: What’s the Deal?

Whether or not you caught the SpaceX Crew Dragon launch this past weekend, here’s your chance to learn why this mission, known as Demo-1, is such a big deal.

The First of its Kind

Demo-1 is the first flight test of an American spacecraft designed for humans built and operated by a commercial company. 

Liftoff

The SpaceX Crew Dragon lifted off at 2:49 a.m. EST Saturday, March 2, on the company’s Falcon 9 rocket from Kennedy Space Center. 

This was the first time in history a commercially-built American crew spacecraft and rocket launched from American soil. 

A New Era in Human Spaceflight

Upon seeing the arriving spacecraft, NASA astronaut Anne McClain snapped a photo from the International Space Station: “Welcome to a new era in human spaceflight.” 

Docking the Dragon

After making 18 orbits of Earth, the Crew Dragon spacecraft successfully attached to the International Space Station’s Harmony module at 5:51 a.m. EST Sunday, March 3. The Crew Dragon used the station’s new international docking adapter for the first time since astronauts installed it in August 2016. 

The docking phase, in addition to the return and recovery of Crew Dragon, are critical to understanding the system’s ability to support crew flights.

Opening the Hatch

After opening the hatch between the two spacecraft, the crewmates configured Crew Dragon for its stay. 

They installed a ventilation system that cycles air from Crew Dragon to the station, installed window covers and checked valves. After that, the crew was all set for a welcoming ceremony for the visiting vehicle. 

Ripley and Little Earth

Although the test is uncrewed, that doesn’t mean the Crew Dragon is empty. Along for the ride was Ripley, a lifelike test device outfitted with sensors to provide data about potential effects on future astronauts. (There is also a plush Earth doll included inside that can float in the microgravity!)

Inside the Dragon

For future operational missions, Crew Dragon will be able to launch as many as four crew members and carry more than 220 pounds of cargo. This will increase the number of astronauts who are able to live onboard the station, which will create more time for research in the unique microgravity environment.

Integration

Since the arrival of SpaceX Crew Dragon, the three Expedition 58 crew members have returned to normal operations (with some new additions to the team!) 

Undocking

The Crew Dragon is designed to stay docked to station for up to 210 days, although the spacecraft used for this flight test will remain docked to the space station for only five days, departing Friday, March 8. (We will be providing live coverage — don’t miss it!)

SpaceX and NASA

Elon Musk, CEO and lead designer at SpaceX, expressed appreciation for NASA’s support: “SpaceX would not be here without NASA, without the incredible work that was done before SpaceX even started and without the support after SpaceX did start.”

Preparation for Demo-2

NASA and SpaceX will use data from Demo-1 to further prepare for Demo-2, the crewed flight test that will carry NASA astronauts and Doug Hurley and Bob Behnken to the International Space Station. NASA will validate the performance of SpaceX’s systems before putting crew on board for the Demo-2 flight, currently targeted for July 2019.

Demo-1: So What?

Demo-1 is a big deal because it demonstrates NASA and commercial companies working together to advance future space exploration! With Demo-1’s success, NASA and SpaceX will begin to prepare to safely fly astronauts to the orbital laboratory.

Optical Communications: Explore Lasers in Space

When we return to the Moon, much will seem unchanged since humans first arrived in 1969. The flags placed by Apollo astronauts will be untouched by any breeze. The footprints left by man’s “small step” on its surface will still be visible across the Moon’s dusty landscape.

Our next generation of lunar explorers will require pioneering innovation alongside proven communications technologies. We’re developing groundbreaking technologies to help these astronauts fulfill their missions.

In space communications networks, lasers will supplement traditional radio communications, providing an advancement these explorers require. The technology, called optical communications, has been in development by our engineers over decades.

Optical communications, in infrared, has a higher frequency than radio, allowing more data to be encoded into each transmission. Optical communications systems also have reduced size, weight and power requirements. A smaller system leaves more room for science instruments; a weight reduction can mean a less expensive launch, and reduced power allows batteries to last longer.

On the path through this “Decade of Light,” where laser joins radio to enable mission success, we must test and demonstrate a number of optical communications innovations.

The Laser Communications Relay Demonstration (LCRD) mission will send data between ground stations in Hawaii and California through a spacecraft in an orbit stationary relative to Earth’s rotation. The demo will be an important first step in developing next-generation Earth-relay satellites that can support instruments generating too much data for today’s networks to handle.

The Integrated LCRD Low-Earth Orbit User Modem and Amplifier-Terminal will provide the International Space Station with a fully operational optical communications system. It will communicate data from the space station to the ground through LCRD. The mission applies technologies from previous optical communications missions for practical use in human spaceflight.

In deep space, we’re working to prove laser technologies with our Deep Space Optical Communications mission. A laser’s wavelength is smaller than radio, leaving less margin for error in pointing back at Earth from very, very far away. Additionally, as the time it takes for data to reach Earth increases, satellites need to point ahead to make sure the beam reaches the right spot at the right time. The Deep Space Optical Communications mission will ensure that our communications engineers can meet those challenges head-on.

An integral part of our journey back to the Moon will be our Orion spacecraft. It looks remarkably similar to the Apollo capsule, yet it hosts cutting-edge technologies. NASA’s Laser Enhanced Mission Communications Navigation and Operational Services (LEMNOS) will provide Orion with data rates as much as 100 times higher than current systems.

LEMNOS’s optical terminal, the Orion EM-2 Optical Communications System, will enable live, 4K ultra-high-definition video from the Moon. By comparison, early Apollo cameras filmed only 10 frames per second in grainy black-and-white. Optical communications will provide a “giant leap” in communications technology, joining radio for NASA’s return to the Moon and the journey beyond.

NASA’s Space Communications and Navigation program office provides strategic oversight to optical communications research. At NASA’s Goddard Space Flight Center in Greenbelt, Maryland, the Exploration and Space Communications projects division is guiding a number of optical communications technologies from infancy to fruition. If you’re ever near Goddard, stop by our visitor center to check out our new optical communications exhibit. For more information, visit nasa.gov/SCaN and esc.gsfc.nasa.gov.

Hostile and Closed Environments, Hazards at Close Quarters

A human journey to Mars, at first glance, offers an inexhaustible amount of complexities. To bring a mission to the Red Planet from fiction to fact, NASA’s Human Research Program has organized some of the hazards astronauts will encounter on a continual basis into five classifications.

A spacecraft is not only a home, it’s also a machine. NASA understands that the ecosystem inside a vehicle plays a big role in everyday astronaut life.

Important habitability factors include temperature, pressure, lighting, noise, and quantity of space. It’s essential that astronauts are getting the requisite food, sleep and exercise needed to stay healthy and happy. The space environment introduces challenges not faced on Earth.

Technology, as often is the case with out-of-this-world exploration, comes to the rescue! Technology plays a big role in creating a habitable home in a harsh environment and monitoring some of the environmental conditions.

Astronauts are also asked to provide feedback about their living environment, including physical impressions and sensations so that the evolution of spacecraft can continue addressing the needs of humans in space.

Exploration to the Moon and Mars will expose astronauts to five known hazards of spaceflight, including hostile and closed environments, like the closed environment of the vehicle itself. To learn more, and find out what NASA’s Human Research Program is doing to protect humans in space, check out the "Hazards of Human Spaceflight" website. Or, check out this week’s episode of “Houston We Have a Podcast,” in which host Gary Jordan further dives into the threat of hostile and closed environments with Brian Crucian, NASA immunologist at the Johnson Space Center.

Gravity, Hazard of Alteration

A human journey to Mars, at first glance, offers an inexhaustible amount of complexities. To bring a mission to the Red Planet from fiction to fact, NASA’s Human Research Program has organized some of the hazards astronauts will encounter on a continual basis into five classifications.

The variance of gravity fields that astronauts will encounter on a mission to Mars is the fourth hazard.

On Mars, astronauts would need to live and work in three-eighths of Earth’s gravitational pull for up to two years. Additionally, on the six-month trek between the planets, explorers will experience total weightlessness. 

Besides Mars and deep space there is a third gravity field that must be considered. When astronauts finally return home they will need to readapt many of the systems in their bodies to Earth’s gravity.

To further complicate the problem, when astronauts transition from one gravity field to another, it’s usually quite an intense experience. Blasting off from the surface of a planet or a hurdling descent through an atmosphere is many times the force of gravity.

Research is being conducted to ensure that astronauts stay healthy before, during and after their mission. Specifically researchers study astronauts’ vision, fine motor skills, fluid distribution, exercise protocols and response to pharmaceuticals.

Meet Our New Flight Directors!

We just hired six new flight directors to join a unique group of individuals who lead human spaceflights from mission control at our Johnson Space Center in Houston.

A flight director manages all human spaceflight missions and related test flights, including International Space Station missions, integration of new American-made commercial spacecraft and developing plans for future Orion missions to the Moon and beyond. 

Only 97 people have served as flight directors, or are in training to do so, in the 50-plus years of human spaceflight. That’s fewer than the over 300 astronauts! We talked with the new class about their upcoming transitions, how to keep calm in stressful situations, the importance of human spaceflight and how to best learn from past mistakes. Here’s what they had to say…

Allison Bollinger

Allison is from Lancaster, Ohio and received a BS in Aerospace Engineering from Purdue University. She wanted to work at NASA for as long as she can remember. “I was four-and-a-half when Challenger happened,” she said. “It was my first childhood memory.” Something in her clicked that day. “After, when people asked what I wanted to be when I grew up, I said an astronaut.” 

By high school a slight fear of heights, a propensity for motion sickness and an aptitude for engineering shifted her goal a bit. She didn’t want to be an astronaut. “I wanted to train astronauts,” she said. Allison has most recently worked at our Neutral Buoyancy Lab managing the daily operations of the 40-ft-deep pool the astronauts use for spacewalk training! She admits she’ll miss “the smell of chlorine each day. Coming to work at one of the world’s largest pools and training astronauts is an incredible job,” she says. But she’s excited to be back in mission control, where in a previous role she guided astronauts through spacewalks. 

She’s had to make some tough calls over the years. So we asked her if she had any tips for when something… isn’t going as planned. She said, “It’s so easy to think the sky is falling. Take a second to take a deep breath, and then you’ll realize it’s not as bad as you thought.”

Adi Boulos

Adi is from Chicago, Illinois and graduated from the University of Illinois Urbana Champaign with a BS in Aerospace Engineering. He joined us in 2008 as a member of the very first group of flight controllers that specialize in data handling and communications and tracking systems aboard the space station. 

Most recently he served as the group lead in the Avionics Trainee group, which he loved. “I was managing newer folks just coming to NASA from college and getting to become flight controllers,” he said. “I will miss getting to mentor them from day one.” But he’s excited to start his new role alongside some familiar faces already in mission control. “It’s a great group of people,” he said of his fellow 2018 flight director class. “The six of us, we mesh well together, and we are all from very diverse backgrounds.” 

As someone who has spent most of his career supporting human spaceflight and cargo missions from mission control, we asked him why human spaceflight is so important. He had a practical take. “It allows us to solve problems we didn’t know we had,” he said. “For example, when we went to the moon, we had to solve all kinds of problems on how to keep humans alive for long-duration flights in space which directly impacts how we live on the ground. All of the new technology we develop for living in space, we also use on the ground.”

Marcos Flores

Marcos is from Caguas, Puerto Rico and earned a BS in Mechanical Engineering from the University of Puerto Rico and an MS in Aerospace Engineering from Purdue University. Spanish is his first language; English is his second. 

The first time he came to the Continental US was on a trip to the Kennedy Space Center in Florida as a kid! “I always knew I wanted to work for NASA,” he said. “And I knew I wanted to be an engineer because I liked to break things to try to figure out how they worked.” He joined us in 2010 as an intern in a robotics laboratory working on conceptual designs for an experimental, autonomous land rover. He later transitioned to the space station flight control team, where he has led various projects, including major software transitions, spacewalks and commercial cargo missions! 

He shares his new coworkers’ thoughts on the practical aspects of human spaceflight and believes it’s an expression of our “drive to explore” and our “innate need to know the world and the universe better.” But for him, “It’s more about answering the fundamental questions of where we come from and where we’re headed.”

Pooja Jesrani

Pooja graduated from The University of Texas at Austin with a BS in Aerospace Engineering. She began at NASA in 2007 as a flight controller responsible for the motion control system of the International Space Station. She currently works as a Capsule Communicator, talking with the astronauts on the space station, and on integration with the Boeing Starliner commercial crew spacecraft. 

She has a two-year-old daughter, and she’s passionate about motherhood, art, fashion, baking, international travel and, of course, her timing as a new flight director! “Not only have we been doing International Space Station operations continuously, and we will continue to do that, but we are about to launch U.S. crewed vehicles off of U.S. soil for the first time since the space shuttle in 2011. Exploration is ramping up and taking us back to the moon!” she said.” “By the time we get certified, a lot of the things we will get to do will be next-gen.”  

We asked her if she had any advice for aspiring flight directors who might want to support such missions down the road. “Work hard every day,” she said. “Every day is an interview. And get a mentor. Or multiple mentors. Having mentorship while you progress through your career is very important, and they really help guide you in the right direction.”

Paul Konyha

Paul was born in Manhasset, NY, and has a BS in Mechanical Engineering from Louisiana Tech University, a Master’s of Military Operational Arts and Science from Air University, and an MS in Astronautical Engineering from the University of Southern California. He began his career as an officer in the United States Air Force in 1996 and authored the Air Force’s certification guide detailing the process through which new industry launch vehicles (including SpaceX’s Falcon 9) gain approval to launch Department of Defense (DoD) payloads. 

As a self-described “Star Wars kid,” he has always loved space and, of course, NASA! After retiring as a Lieutenant Colonel in 2016, Paul joined Johnson Space Center as the Deputy Director of the DoD Space Test Program Human Spaceflight Payloads Office. He’s had a rich career in some pretty high-stakes roles. We asked him for advice on handling stress and recovering from life’s occasional setbacks. “For me, it’s about taking a deep breath, focusing on the data and trying not to what if too much,” he said. “Realize that mistakes are going to happen. Be mentally prepared to know that at some point it’s going to happen—you’re going to have to do that self-reflection to understand what you could’ve done better and how you’ll fix it in the future. That constant process of evaluation and self-reflection will help you get through it.”

Rebecca Wingfield

Rebecca is from Princeton, Kentucky and has a BS in Mechanical Engineering from the University of Kentucky and an MS in Systems Engineering from the University of Houston, Clear Lake. She joined us in 2007 as a flight controller responsible for maintenance, repairs and hardware installations aboard the space station. 

Since then, she’s worked as a capsule communicator for the space station and commercial crew programs and on training astronauts. She’s dedicated her career to human spaceflight and has a special appreciation for the program’s long-term benefits. “As our human race advances and we change our planet in lots of different ways, we may eventually need to get off of it,” she said. “There’s no way to do that until we explore a way to do it safely and effectively for mass numbers of people. And to do that, you have to start with one person.” We asked her if there are any misconceptions about flight directors. She responded, “While they are often steely-eyed missile men and women, and they can be rough around the edges, they are also very good mentors and teachers. They’re very much engaged in bringing up the next generation of flight controllers for NASA.”

Congrats to these folks on leading the future of human spaceflight!

Welcome Home HERA Mission XVII!

With the Human Exploration Research Analog (HERA) habitat, we complete studies to prepare us for exploration to asteroids, Mars, and the Moon… here on Earth! The studies are called analogs, and they simulate space missions to study how different aspects of deep space affect humans. During a HERA mission, the crew (i.e., the research participants) live and work very much as astronauts do, with minimal contact with anyone other than Mission Control for 45 days.

The most recent study, Mission XVII, just “returned to Earth” on June 18. (i.e., the participants egressed, or exited the habitat at our Johnson Space Center in Houston after their 45-day study.) We talked with the crew, Ellie, Will, Chi, and Michael, about the experience. Here are some highlights!

Why did you decide to participate in HERA Mission XVII?

HERA Mission VXII participants (from left to right) Ellie, Will, Chi, and Michael.

“My master’s is in human factors,” said Chi, who studies the interaction between humans and other systems at Embry-Riddle Aeronautical University. “I figured this would be a cool way to study the other side of the table and actually participate in an analog.” For Michael, who holds a PhD in aerospace engineering and researches immunology and radio biology, it was an opportunity to experience life as an astronaut doing science in space. “I’ve flown [experiments] on the space station and shuttle,” he said. “Now I wanted to see the other side.” For Will, a geosciences PhD, it provided an opportunity to contribute to space exploration and neuroscience, which he considers two of the biggest fields with the most potential in science. “Here, we have this project that is the perfect intersection of those two things,” he said. And Ellie, a pilot in the Air Force, learned about HERA while working on her master’s thesis on Earth and space analogs and how to improve them for deep-space studies. “A lot of my interests are similar to Chi’s,” she said. “Human factors and physiological aspects are things that I find very fascinating.”

NASA missions all have patches, and HERA Mission XVII is no different. Did you get to design your patch?

HERA Mission VXII patch, which reads “May the Force be with you” in Latin and features Star Wars iconography. It’s a reference to the mission’s start date, May 4th aka Star Wars Day!

“We did!” They said …with a little the help from Michael’s brother, who is a designer. He drew several different designs based on the crew’s ideas. They picked one and worked together on tweaks. “We knew we were going [inside the habitat] on May Fourth,” Michael said. “We knew it would be Star Wars Day. So we did a Star Wars theme.” The patch had to come together fairly quickly though, since a Star Wars Day “launch” wasn’t the initial plan. “We were supposed to start two weeks earlier,” Ellie said. “It just so happened the new start date was May the Fourth!” Along with the Star Wars imagery, the patch includes a hurricane symbol, to pay tribute to hurricane Harvey which caused a previous crew to end their mission early, and an image of the HERA habitat. Will joked that designing the patch was “our first team task.”

How much free time did you have and what did you do with it?

HERA Mission XVII crew looking down the ladders inside the habitat.

“It was a decent amount,” Michael said. “I could have used more on the harder days, but in a way it’s good we didn’t have more because it’s harder to stay awake when you have nothing to do.” (The mission included a sleep reduction study, which meant the crew only got five hours of sleep a night five days a week.) “With the time I did have, I read a lot,” he said. He also drew, kept a journal, and “wrote bad haikus.” Because of the sleep study, Ellie didn’t read as much. “For me, had I tried to read or sit and do anything not interactive, I would have fallen asleep,” she said.

The crew’s art gallery, where they hung drawing and haikus they wrote.

Journaling and drawing were popular ways to pass the time. “We developed a crew art gallery on one of the walls,” Will said. They also played board games—in particular a game where you score points by making words with lettered tiles on a 15×15 grid. (Yes that one!) “Playing [that game] with two scientists wasn’t always fun though,” Ellie joked, referencing some of the more obscure vocabulary words Will and Michael had at the ready. “I was like, ‘What does that word mean?’ ‘Well that word means lava flow,” she said laughing. (The rest of the crew assured us she fared just fine.)

Chi tried reading, but found it difficult due to the dimmed lights that were part of an onboard light study. She took on a side project instead: 1000 paper cranes. “There is a story in Japan—I’m half Japanese—that if you make a 1000 cranes, it’s supposed to grant you a wish,” she said. She gave hers to her grandmother.

The whole crew having dinner together on “Sophisticated Saturdays!” From left to right: Will, Ellie, Chi, and Michael. They’re wearing their Saturday best, which includes the usual research equipment.

On weekends, the crew got eight hours of sleep, which they celebrated with “Sophisticated Saturdays!” “Coming in, we all brought an outfit that was a little fancy,” Ellie said. (Like a tie, a vest, an athletic dress—that kind of thing.) “We would only put it on Saturday evenings, and we’d have dinner on the first level at the one and only table we could all sit at and face each other,” she said. “We would pretend it was a different fancy restaurant every week.”

The table set for a “civilized” Saturday dinner. Once the crew’s hydroponics grew, they were able to add some greenery to the table.

“It was a way to feel more civilized,” Will said, who then offered another great use of their free time: establishing good habits. “I would use the free time to journal, for example. I’d just keep it up every day. That and stretching. Hydrating. Flossing.”

Like real astronauts, you were in contact with Mission Control and further monitored by HERA personnel. Was it weird being on camera all the time?

HERA personnel and the monitors they use for a typical HERA mission.

“I was always aware of it,” Michael said, “but I don’t think it changed my behavior. It’s not like I forgot about it. It was always there. I just wasn’t willing to live paranoid for 45 days.” Ellie agreed. “It was always in the back of my mind,” she said, further adding that they wore microphones and various other sensors. “We were wired all the time,” she said.

After the study, the crew met up with the people facilitating the experiments, sometimes for the first time. “It was really fun to meet Mission Control afterwards,” Will said. “They had just been this voice coming from the little boxes. It was great getting to meet them and put faces to the voices,” he said. “Of course, they knew us well. Very well.”

Exploring an Asteroid Without Leaving Earth

This 45 day mission – which began May 5, 2018 and ends today, June 18 – will help our researchers learn how isolation and close quarters affect individual and group behavior. This study at our Johnson Space Center prepares us for long duration space missions, like a trip to an asteroid or even to Mars.

The Human Research Exploration Analog (HERA) that the crew members will be living in is one compact, science-making house. But unlike in a normal house, these inhabitants won’t go outside for 45 days. Their communication with the rest of planet Earth will also be very limited, and they won’t have any access to internet. So no checking social media, kids!

The only people they will talk with regularly are mission control and each other.

The HERA XVII crew is made up of 2 men and 2 women, selected from the Johnson Space Center Test Subject Screening (TSS) pool. The crew member selection process is based on a number of criteria, including criteria similar to what is used for astronaut selection. The four would-be astronauts are:

William Daniels

Chiemi Heil

Eleanor Morgan

Michael Pecaut

What will they be doing?

The crew are going on a simulated journey to an asteroid, a 715-day journey that we compress into 45 days. They will fly their simulated exploration vehicle around the asteroid once they arrive, conducting several site surveys before 2 of the crew members will participate in a series of virtual reality spacewalks.

They will also be participating in a suite of research investigations and will also engage in a wide range of operational and science activities, such as growing and analyzing plants and brine shrimp, maintaining and “operating” an important life support system, exercising on a stationary bicycle or using free weights, and sharpening their skills with a robotic arm simulation.

During the whole mission, they will consume food produced by the Johnson Space Center Food Lab – the same food that the astronauts enjoy on the International Space Station – which means that it needs to be rehydrated or warmed in a warming oven.

This simulation means that even when communicating with mission control, there will be a delay on all communications ranging from 1 to 5 minutes each way.

A few other details:

The crew follows a timeline that is similar to one used for the space station crew.

They work 16 hours a day, Monday through Friday. This includes time for daily planning, conferences, meals and exercise.

Mission: May 5 - June 18, 2018

But beware! While we do all we can to avoid crises during missions, crews need to be able to respond in the event of an emergency. The HERA crew will conduct a couple of emergency scenario simulations, including one that will require them to respond to a decrease in cabin pressure, potentially finding and repairing a leak in their spacecraft.

Throughout the mission, researchers will gather information about living in confinement, teamwork, team cohesion, mood, performance and overall well-being. The crew members will be tracked by numerous devices that each capture different types of data.

Astronaut Journal Entry - Launch & Docking

Currently, six humans are living and working on the International Space Station, which orbits 250 miles above our planet at 17,500mph. Below you will find a real journal entry, written in space, by NASA astronaut Scott Tingle.

To read more entires from this series, visit our Space Blogs on Tumblr.

The launch went as planned. Our Soyuz spacecraft did a great job getting the three of us to the International Space Station (ISS).  

A week later, it all seems like a blur. The bus driver played me a video of my family and friends delivering their good luck messages. After exiting the bus at the launch pad, I was fortunate to have the Soyuz chief designer (Roman) and NASA’s associate administrator for Human Exploration and Operations (Bill Gerstenmaier) walk me to the stairs and elevator that would take us to the top of the rocket for boarding. The temperature at the pad was approximately -17 degrees centigrade, and we were wearing the Russian Polar Bear suits over our spacesuits in order to stay warm. Walking in these suits is a little hard, and I was happy to have Roman and Bill helping me. 

We walked into the fog created by the systems around the rocket, climbed the ladder, and waved goodbye. My last words before launch were to Bill, “Boiler Up!”. Bill is a fellow and very well-known Boilermaker. We strapped in, and the launch and docking were nominal. But I will add that the second stage cutoff and separation, and ignition of the third stage was very exciting. We were under approximately 4 Gs when the engine cutoff, which gave us a good jolt forward during the deceleration and then a good jolt back into the seat after the third stage ignited. I looked at Anton and we both began to giggle like school children.

We spent two days in orbit as our phase angle aligned with ISS. Surprisingly, I did not feel sick. I even got 4 hours of sleep the first night and nearly 6 hours the second night. Having not been able to use my diaper while sitting in the fetal position during launch, it was nice to get out of our seats and use the ACY (Russian toilet). Docking was amazing. I compared it to rendezvousing on a tanker in a fighter jet, except the rendezvous with ISS happened over a much larger distance. As a test pilot, it was very interesting to watch the vehicle capture and maintain the centerline of ISS’s MRM-1 docking port as well as capturing and maintaining the required speed profile. 

Just like landing at the ship, I could feel the vehicle’s control system (thrusters) making smaller and faster corrections and recorrections. In the flight test world, this is where the “gains” increase rapidly and where any weaknesses in the control system will be exposed. It was amazing to see the huge solar arrays and tons of equipment go by my window during final approach. What an engineering marvel the ISS is. Smooth sailing right into the docking port we went!  

About an hour later, after equalizing pressures between the station and Soyuz, we opened the hatch and greeted our friends already onboard. My first view of the inside of the space station looked pretty close to the simulators we have been training in for the last several years. My first words were, “Hey, what are you guys doing at Building 9?”. Then we tackled each other with celebratory hugs!

Astronaut Journal Entry - Pre-Launch

Currently, six humans are living and working on the International Space Station, which orbits 250 miles above our planet at 17,500mph. Below you will find a real journal entry written by NASA astronaut Scott Tingle.

To read more entires from this series, visit our Space Blogs on Tumblr.

Our crew just finished the final training event before the launch. Tomorrow, at 13:20 local time (Baikonur), we will strap the Soyuz MS-07 spacecraft to our backs and fly it to low Earth orbit. We will spend 2.5 days in low Earth orbit before docking to the MRM-1 docking port on the International Space Station (ISS). There we will begin approximately 168 days of maintenance, service and science aboard one of the greatest engineering marvels that humans have ever created.

Today was bittersweet. Ending a 2-year process of intense training was welcomed by all of us. We are very tired. Seeing our families for the last time was difficult. I am pretty lucky, though. My wife, Raynette, and the kids have grown up around military service and are conditioned to endure the time spent apart during extended calls-to-duty. We are also very much anticipating the good times we will have upon my return in June. Sean and Amy showed me a few videos of them mucking it up at Red Square before flying out to Baikonur. Eric was impressed with the Russian guards marching in to relieve the watch at Red Square. Raynette was taking it all in stride and did not seem surprised by any of it. I think I might have a family of mutants who are comfortable anywhere. Nice! And, by the way, I am VERY proud of all of them!

Tomorrow’s schedule includes a wake-up at 04:00, followed by an immediate medical exam and light breakfast. Upon returning to our quarters, we will undergo a few simple medical procedures that should help make the 2.5-day journey to ISS a little more comfortable. I’ve begun prepping with motion sickness medication that should limit the nausea associated with the first phases of spaceflight. I will continue this effort through docking. This being my first flight, I’m not sure how my body will respond and am taking all precautions to maintain a good working capability. The commander will need my help operating the vehicle, and I need to not be puking into a bag during the busy times. We suit up at 09:30 and then report to the State Commission as “Готовы к Полёту”, or “Ready for Flight”. We’ll enter the bus, wave goodbye to our friends and family, and then head out to the launch pad. Approximately 2 kilometers from the launch pad, the bus will stop. 

The crew will get out, pee on the bus’s tire, and then complete the last part of the drive to the launch pad. This is a traditional event first done by Yuri Gagarin during his historic first flight and repeated in his honor to this day. We will then strap in and prepare the systems for launch. Next is a waiting game of approximately 2 hours. Ouch. The crew provided five songs each to help pass the time. My playlist included “Born to Run” (Springsteen), “Sweet Child O’ Mine” (Guns and Roses), “Cliffs of Dover” (Eric Johnson), “More than a Feeling” (Boston), and “Touch the Sky” (Rainbow Bridge, Russian). Launch will happen precisely at 13:20.

I think this sets the stage. It’s 21:30, only 6.5 hours until duty calls. Time to get some sleep. If I could only lower my level of excitement!

Exploring an Asteroid Without Leaving Earth

This 45 day mission – which begins Feb. 1, 2018 – will help our researchers learn how isolation and close quarters affect individual and group behavior. This study at our Johnson Space Center prepares us for long duration space missions, like a trip to an asteroid or even to Mars.

The Human Research Exploration Analog (HERA) that the crew members will be living in is one compact, science-making house. But unlike in a normal house, these inhabitants won’t go outside for 45 days. Their communication with the rest of planet Earth will also be very limited, and they won’t have any access to internet. So no checking social media, kids!

The only people they will talk with regularly are mission control and each other.

The HERA XVI crew is made up of 2 men and 2 women, selected from the Johnson Space Center Test Subject Screening (TSS) pool. The crew member selection process is based on a number of criteria, including criteria similar to what is used for astronaut selection. The four would-be astronauts are:

Kent Kalogera

Jennifer Yen

Erin Hayward

Gregory Sachs

What will they be doing?

The crew are going on a simulated journey to an asteroid, a 715-day journey that we compress into 45 days. They will fly their simulated exploration vehicle around the asteroid once they arrive, conducting several site surveys before 2 of the crew members will participate in a series of virtual reality spacewalks.

They will also be participating in a suite of research investigations and will also engage in a wide range of operational and science activities, such as growing and analyzing plants and brine shrimp, maintaining and “operating” an important life support system, exercising on a stationary bicycle or using free weights, and sharpening their skills with a robotic arm simulation. 

During the whole mission, they will consume food produced by the Johnson Space Center Food Lab – the same food that the astronauts enjoy on the International Space Station – which means that it needs to be rehydrated or warmed in a warming oven.

This simulation means that even when communicating with mission control, there will be a delay on all communications ranging from 1 to 5 minutes each way.

A few other details:

The crew follows a timeline that is similar to one used for the space station crew.

They work 16 hours a day, Monday through Friday. This includes time for daily planning, conferences, meals and exercise.

Mission: February 1, 2018 - March 19, 2018

But beware! While we do all we can to avoid crises during missions, crews need to be able to respond in the event of an emergency. The HERA crew will conduct a couple of emergency scenario simulations, including one that will require them to respond to a decrease in cabin pressure, potentially finding and repairing a leak in their spacecraft.

Throughout the mission, researchers will gather information about living in confinement, teamwork, team cohesion, mood, performance and overall well-being. The crew members will be tracked by numerous devices that each capture different types of data.

Expedition 52 Begins Aboard Space Station

When humans launch to the International Space Station, they are members of expeditions. An expedition is long duration stay on the space station. The first expedition started when the crew docked to the station on Nov. 2, 2000.

Expedition 52 began in June 2017 aboard the orbiting laboratory and will end in September 2017. 

FUN FACT: Each Expedition begins with the undocking of the spacecraft carrying the departing crew from the previous Expedition. So Expedition 52 began with the undocking of the Soyuz MS-03 spacecraft that brought Expedition 51 crew members Oleg Novitskiy and Thomas Pesquet back to Earth, leaving NASA astronauts Peggy Whitson and Jack Fischer and Roscosmos cosmonaut Fyodor Yurchikhin aboard the station to await the arrival of the rest of the Expedition 52 crew in July.

This expedition includes dozens of out of this world science investigations and a crew that takes #SquadGoals to a whole new level. 

Take a look below to get to know the crew members and some of the science that will occur during the space station’s 52nd expedition.

What will the crew be doing during Expedition 52?

In addition to one tentatively planned spacewalk, crew members will conduct scientific investigations that will demonstrate more efficient solar arrays, study the physics of neutron stars, study a new drug to fight osteoporosis and study the adverse effects of prolonged exposure to microgravity on the heart.

Roll-Out Solar Array (ROSA)

Solar panels are an efficient way to generate power, but they can be delicate and large when used to power a spacecraft or satellites. They are often tightly stowed for launch and then must be unfolded when the spacecraft reaches orbit.

The Roll-Out Solar Array (ROSA), is a solar panel concept that is lighter and stores more compactly for launch than the rigid solar panels currently in use. ROSA has solar cells on a flexible blanket and a framework that rolls out like a tape measure.  

Neutron Star Interior Composition Explored (NICER)

Neutron stars, the glowing cinders left behind when massive stars explode as supernovas, are the densest objects in the universe, and contain exotic states of matter that are impossible to replicate in any ground lab.

The Neutron Star Interior Composition Explored (NICER) payload, affixed to the exterior of the space station, studies the physics of these stars, providing new insight into their nature and behavior.

Systemic Therapy of NELL-1 for Osteoporosis (Rodent Research-5)

When people and animals spend extended periods of time in space, they experience bone density loss. The Systemic Therapy of NELL-1 for osteoporosis (Rodent Research-5) investigation tests a new drug that can both rebuild bone and block further bone loss, improving health for crew members.

Fruit Fly Lab-02

Exposure to reduced gravity environments can result in cardiovascular changes such as fluid shifts, changes in total blood volume, heartbeat and heart rhythm irregularities, and diminished aerobic capacity. The Fruit Fly Lab-02 study will use the fruit fly (Drosophila melanogaster) to better understand the underlying mechanisms responsible for the adverse effects of prolonged exposure to microgravity on the heart.

Watch their progress HERE!

Expedition 52 Mission Patch 

Our planet is shown surrounded by an imaginary constellation shaped like a house, depicting the theme of the patch: “The Earth is our home.” It is our precious cradle, to be preserved for all future generations. The house of stars just touches the Moon, acknowledging the first steps we have already taken there, while Mars is not far away, just beyond the International Space Station, symbolized by the Roman numeral “LII,” signifying the expedition number. 

The planets Saturn and Jupiter, seen orbiting farther away, symbolize humanity’s exploration of deeper space, which will begin soon. A small Sputnik is seen circling the Earth on the same orbit with the space station, bridging the beginning of our cosmic quest till now: Expedition 52 will launch in 2017, sixty years after that first satellite. Two groups of crew names signify the pair of Soyuz vehicles that will launch the astronauts of Expedition 52 to the Station.
