Will NASA send astronauts to the moon again or any other planet within the next ten years?

@nasaorion spacecraft will launch on the Space Launch system (the largest spacecraft every built, even bigger than the Saturn V rocket!).  Both are under construction @nasa currently, and this is the spacecraft that will take us beyond the low earth orbit of the International Space Station, whether that be the Moon, Mars, or beyond.  We will conduct test missions with astronauts on Orion in the early 2020s, and a first mission will take us 40,000 miles beyond the Moon!

Jessica, first of all, I love you. Second, what's it like being a part of the first class that was 50% female?

Thank you!  The best part is that I think the fact that our class is 50% female simply reflects how far our society has come, and that is a great thing!  To us, there really is no difference on whether or not we are female or male, what backgrounds we come from, etc., we are one team, one family, all contributing to the same cause (which is an extraordinary feeling!).  I’m definitely very proud and honored to be part of the 21st astronaut class.

What are the most important skills an astronaut should have m?

First of all, the basic requirement is a bachelor’s degree in a STEM field, and 3 years of experience (which can also be substituted for by an advanced degree). Other than that, operational experience (things with a technical/active/hands on nature like flying airplanes, SCUBA diving, taking things apart and putting them back together, basic fix-it skills, etc. etc.) is very important, as this is an integral aspect of every day of a space mission.  What we call “expeditionary skills” are also essential, basically the types of things you try to instill in your children, like how to play nicely with others, self care, team care, etc.  I like to think about this on the lines of a camping trip and who you would like to have along with you . . .someone that is competent and can take good care of themselves and their equipment, someone that contributes to the team and helps with group tasks, someone that is good natured and pleasant to be around, etc., someone fun!  These things are increasingly important now that we are regularly doing long duration missions (typical International Space Station mission is 6 months).  Experience living in extreme/remote/isolated environments with small teams is also useful, as it is similar to what we experience as astronauts.     

What is an upcoming project/mission you're most excited for?

It is likely that I’ll be assigned a mission to the International Space Station (ISS) within the next few years.  We’ve had a continuous presence on the Space Station for 17 years now, along with our international partners (Russian Space Agency, European Space Agency, Japanese Space Agency, and Canadian Space Agency).  Missions on the ISS typically last 6 months.  I’m incredibly excited to contribute to the impressive array of scientific experiments that we are conducting every day on ISS (I am a scientist after all!), and very much look forward to the potential of going for a spacewalk and gaining that perspective of gazing down on the fragile blue ball that is our home from above.  Beyond that, being part of test missions on the Orion spacecraft (currently under construction at NASA!) would be an extraordinary opportunity.  The current NASA plan is to send astronauts in Orion in a mission that will go 40,000 miles beyond the Moon in the early 2020s, reaching a distance further than that ever travelled by humans.  I’d certainly be game for that! 

Does all capsules drops in Kazakhstan on return after every mission?

Since the US Space Shuttle retired in 2011, we launch to and return from the Space Station with the Russian Space Agency.  So yes, these capsules (the Soyuz) land in Kazakhstan (or surrounding regions).  However, different spacecrafts have different reentry trajectories, depending on where they aim to land.  As you might recall, the Apollo mission capsules landed in the ocean.  Since Space-X and Boeing are currently building new vehicles so that we will also launch from the US again to get to the International Space Station, these spacecraft will return to the US. For example, you may have seen footage of Space-X cargo vehicles splashing down into the Pacific over the last few years. The Boeing Starliner plans to land on land instead of water. NASA is also currently building the Orion spacecraft, which will take us to destinations beyond low earth orbit (where the Space Station is), whether that be the Moon or Mars or another target.  Orion will also splash down in the ocean.  

How much of a daily threat is "Space junk"?

Good question, as this is a serious issue and one which we must monitor constantly in order to avoid harmful impacts on the International Space Station with objects in space.  For example, the US Space Command in Colorado is monitoring all objects bigger than a few inches in order to assess any potential impact with the Space Station.  We categorize the chance of impact and if there is a high probability, we will actually use thrusters to slightly change the position of the Space Station to avoid the impact.  If it is something that we are unable to avoid, we will have the astronauts shelter in place in their spacecrafts and in case of a catastrophic impact, they will return to Earth.

Hi ! What's your music playlist when you're on a mission ? :)

Luckily I have a lot of friends that already make amazing mixes for me already down here on Earth, so I’m counting on them to set me up well for my first mission.  My favorite genre is Indie rock, though I’m also a fan of jazz and classical music (I grew up playing the piano, flute, piccolo, and saxophone in various bands, wind symphonies, and jazz bands).  Music always succeeds in transforming my mood, I’m continually amazed at its power!  It will definitely be integral to my psychological well-being on a space mission.

What is your favorite sci-fi show about space?

I actually wasn’t a huge sci-fi person growing up, but of course I am a fan of Star Wars.  After graduate school I stumbled upon Battlestar Galactica (the new one) and was definitely hooked, especially since I was living in Vancouver at the time and it was filmed there!  

What was the hardest part in training to go to space?

One of the most challenging parts of space training was learning how to use the space suit.  We weigh over 400 pounds in the space suit, and since it is pressurized, each movement of your hands is like working against an exercise ball.  Since the suit needs to be quite bulky in order to protect us from the environment of space (vacuum, radiation, micrometeoroids, extreme temperature) while doing a spacewalk, it makes body movements a bit awkward.  Dexterity is quite compromised with the bulky gloves as well.  Although it is challenging, however, it is likely also the most rewarding, because, well, you are in a SPACE SUIT!!!  Hopefully I’ll get to do a spacewalk and look down on the our planet from above on a mission to the International Space Station in a few years. 

Does space have a standard time or do you rely on the time zones on Earth while you are in space?

Great question.  Really it is up to the particular space agency/mission which time zone they use.  For example, since the International Space Station is a collaboration between NASA, the Russian Space Agency, the European Space Agency, the Japanese Space Agency, and the Canadian Space Agency, we came up with the compromise of operating on Greenwich Mean Time (GMT).  So, Space Station time is the same as London time!  The International Space Station orbits our planet every 90 minutes, so of course we’re transiting across multiple time zones constantly.  

How hard is it to become an austronaut? I want to start to studie astrophysics and I don't know if I'll ever get any kind of job. Do you have any tips for people like me?

Astrophysics is a perfect field for pursuing any work at NASA!  A degree in a STEM field is a requirement of becoming an astronaut, but other than that there are many possibilities.  One of the best things about the astronaut office is its diversity.  We are scientists, engineers, military pilots, flight test engineers, medical doctors, etc. etc. My biggest tip is to ensure you are pursuing what it is you are passionate about as that’s the only way to truly become exceptional at what you are doing, and most importantly, to be happy doing it.  Passion, hard work, and dedication will get you there.  Good luck!

Home is Where the Astronaut Is…

The International Space Station serves as a home, office and recreation room for astronauts. They share this confined space far above the Earth with crew members from different countries and cultures for as long as six months or more. At the same time, maintaining individual well-being and crew harmony is important for the crew and mission success.

The Culture, Values and Environmental Adaptation in Space (At Home in Space) Investigation, looks at changes in perceptions about home in space and the ways a unique culture may develop aboard the station during a mission. Discover more about this study HERE.

Kate Rubins’ Space Station Science Scrapbook

As a child, Kate Rubins dreamed of being an astronaut and a scientist. During the past four months aboard the International Space Station, that dream came full circle. She became the first person to sequence DNA in space, among other research during her recent mission, adding to her already impressive experience. She holds a doctorate in molecular biology, and previously led a lab of 14 researchers studying viruses, including Ebola.

Here’s a look back at Rubins in her element, conducting research aboard your orbiting laboratory.

Kate inside Destiny, the U.S. Laboratory Module

The U.S. national laboratory, called Destiny, is the primary research laboratory for U.S. payloads, supporting a wide range of experiments and studies contributing to health, safety, and quality of life for people all over the world. 

Destiny houses the Microgravity Science Glovebox (MSG), in which Kate worked on the Heart Cells experiment.

Swabbing for Surface Samples

Microbes that can cause illness could present problems for current and future long duration space missions. 

Understanding what microbe communities thrive in space habitats could help researchers design antimicrobial technology. Here, Kate is sampling various surfaces of the Kibo module for the Microbe-IV investigation.

Culturing Beating Heart Cells in Space

The Heart Cells investigation uses human skin cells that are induced to become stem cells, which can then differentiate into any type of cell. 

Researchers forced the stem cells to grow into human heart cells, which Rubins cultured aboard the space station for one month.

Rubins described seeing the heart cells beat for the first time as “pretty amazing. First of all, there’s a few things that have made me gasp out loud up on board the [space] station. Seeing the planet was one of them, but I gotta say, getting these cells in focus and watching heart cells actually beat has been another pretty big one.”

Innovative Applied Research Experiment from Eli Lilly

The Hard to Wet Surfaces investigation from Eli Lilly, and sponsored by the Center for the Advancement of Science in Space (CASIS), looks at liquid-solid interactions and how certain pharmaceuticals dissolve, which may lead to more potent and effective medicines in space and on Earth. 

Rubins set up vials into which she injected buffer solutions and then set up photography to track how tablets dissolved in the solution in microgravity.

Capturing Dragon

Rubins assisted in the capture of the SpaceX Dragon cargo spacecraft in July. The ninth SpaceX resupply mission delivered more than two thousand pounds of science to the space station. 

Biological samples and additional research were returned on the Dragon spacecraft more than a month later.  

Sliding Science Outside the Station

Science doesn’t just happen inside the space station. External Earth and space science hardware platforms are located at various places along the outside of the orbiting laboratory. 

The Japanese Experiment Module airlock can be used to access the JEM Exposed Facility. Rubins installed the JEM ORU Transfer Interface (JOTI) on the JEM airlock sliding table used to install investigations on the exterior of the orbiting laboratory.

Installing Optical Diagnostic Instrument in the MSG

Rubins installed an optical diagnostic instrument in the Microgravity Science Glovebox (MSG) as part of the Selective Optical Diagnostics Instrument (SODI-DCMIX) investigation. Molecules in fluids and gases constantly move and collide. 

When temperature differences cause that movement, called the Soret effect, scientists can track it by measuring changes in the temperature and movement of mass in the absence of gravity. Because the Soret effect occurs in underground oil reservoirs, the results of this investigation could help us better understand such reservoirs.

The Sequencing of DNA in Space

When Rubins’ expedition began, DNA had never been sequenced in space. Within just a few weeks, she and the Biomolecule Sequencer team had sequenced their one billionth “base” – the unit of DNA - aboard the orbiting laboratory. 

The Biomolecule Sequencer investigation seeks to demonstrate that DNA sequencing in microgravity is possible, and adds to the suite of genomics capabilities aboard the space station.

Studying Fluidic Dynamics with SPHERES

The SPHERES-Slosh investigation examines the way liquids move inside containers in a microgravity environment. The phenomena and mechanics associated with such liquid movement are still not well understood and are very different than our common experiences with a cup of coffee on Earth.

Rockets deliver satellites to space using liquid fuels as a power source, and this investigation plans to improve our understanding of how propellants within rockets behave in order to increase the safety and efficiency of future vehicle designs. Rubins conducted a series of SPHERES-Slosh runs during her mission.

Retrieving Science Samples for Their Return to Earth

Precious science samples like blood, urine and saliva are collected from crew members throughout their missions aboard the orbiting laboratory. 

They are stored in the Minus Eighty-Degree Laboratory Freezer for ISS (MELFI) until they are ready to return to Earth aboard a Soyuz or SpaceX Dragon vehicle.

Measuring Gene Expression of Biological Specimens in Space

Our WetLab-2 hardware system is bringing to the space station the technology to measure gene expression of biological specimens in space, and to transmit the results to researchers on Earth at the speed of light. 

Rubins ran several WetLab-2 RNA SmartCycler sessions during her mission.

Studying the First Expandable Habitat Module on the Space Station

The Bigelow Expandable Activity Module (BEAM) is the first expandable habitat to be installed on the space station. It was expanded on May 28, 2016. 

Expandable habitats are designed to take up less room on a spacecraft, but provide greater volume for living and working in space once expanded. Rubins conducted several evaluations inside BEAM, including air and surface sampling.

Better Breathing in Space and Back on Earth

Airway Monitoring, an investigation from ESA (the European Space Agency), uses the U.S. airlock as a hypobaric facility for performing science. Utilizing the U.S. airlock allows unique opportunities for the study of gravity, ambient pressure interactions, and their effect on the human body. 

This investigation studies the occurrence and indicators of airway inflammation in crew members, using ultra-sensitive gas analyzers to evaluate exhaled air. This could not only help in spaceflight diagnostics, but that also hold applications on earth within diagnostics of similar conditions, for example monitoring of asthma.

Hot Science with Cool Flames

Fire behaves differently in space, where buoyant forces are removed. Studying combustion in microgravity can increase scientists’ fundamental understanding of the process, which could lead to improvement of fire detection and suppression systems in space and on Earth. 

Many combustion experiments are performed in the Combustion Integration Rack (CIR) aboard the space station. Rubins replaced two Multi-user Droplet Combustion Apparatus (MDCA) Igniter Tips as part of the CIR igniter replacement operations.

Though Rubins is back on Earth, science aboard the space station continues, and innovative investigations that seek to benefit humans on Earth and further our exploration of the solar system are ongoing. Follow @ISS_Research to keep up with the science happening aboard your orbiting laboratory.

Living and Working Aboard Station

 Join us on Facebook Live for a conversation with astronaut Kate Rubins and the director of the National Institutes for Health on Tuesday, October 18 at 11:15 a.m. ET.

Astronaut Kate Rubins has conducted out of this world research aboard Earth’s only orbiting laboratory. During her time aboard the International Space Station, she became the first person to sequence DNA in space. On Tuesday, she’ll be live on Facebook with National Institute of Health director Francis Collins, who led the effort to map the human genome. You can submit questions for Kate using the hashtag #SpaceChat on Twitter, or during the live event. Here’s a primer on the science this PhD astronaut has been conducting to help inspire your questions: 

Kate has a background in genomics (a branch of molecular genetics that deals with the study of genomes,specifically the identification and sequencing of their constituent genes and the application of this knowledge in medicine, pharmacy,agriculture, and other fields). When she began her tenure on the station, zero base pairs of DNA had been sequenced in space. Within just a few weeks, she and the Biomolecule Sequencer team had sequenced their one billionth base of DNA aboard the orbital platform.

“I [have a] genomics background, [so] I get really excited about that kind of stuff,” Rubins said in a downlink shortly after reaching the one billion base pairs sequenced goal.

NASA and Its Partnerships

We’re not doing this alone. Just like the DNA sequencing was a collaborative project with industry, so is the Eli Lilly Hard to Wet Surfaces investigation, which is a partnership between CASIS and Eli Lilly Co. In this experiment aboard the station, astronauts will study how certain materials used in the pharmaceutical industry dissolve in water while in microgravity. Results from this investigation could help improve the design of tablets that dissolve in the body to deliver drugs, thereby improving drug design for medicines used in space and on Earth.

With our colleagues at the Stanford University School of Medicine, we’re also investigating the effects of spaceflight on stem cell-derived heart cells, specifically how heart muscle tissue, contracts, grows and changes  in microgravity and how those changes vary between subjects. Understanding how heart muscle cells change in space improves efforts for studying disease, screening drugs and conducting cell replacement therapy for future space missions. Learn more:

+Weekly Recap From the Expedition Lead Scientist for Aug. 18, 2016 

It’s Not Just Medicine

Kate and her crew mates have also worked on the combustion experiments.

Kate has also worked on the Bigelow Expandable Activity Module (BEAM), an experimental expandable capsule that docks with the station. As we work on our Journey to Mars, future space habitats  are a necessity. BEAM, designed for Mars or other destinations, is a lightweight and relatively simple to construct solution. Kate has recently examined BEAM, currently attached to the station, to take measurements and install sensors.

Kate recently performed a harvest of the Plant RNA Regulation experiment, by removing seed cassettes and stowing them in cold stowage.

The Plant RNA Regulation investigation studies the first steps of gene expression involved in development of roots and shoots. Scientists expect to find new molecules that play a role in how plants adapt and respond to the microgravity environment of space, which provides new insight into growing plants for food and oxygen supplies on long-duration missions. Read more about the experiment:

+Plant RNA Harvest

NASA Astronaut Kate Rubins is participating in several investigations examining changes in her body as a result of living in space. Some of these changes are similar to issues experienced by our elderly on Earth; for example, bone loss (osteoporosis), cardiovascular deconditioning, immune dysfunction, and muscle atrophy. Understanding these changes and how to prevent them in astronauts off the Earth may help improve health for all of us on the Earth. In additional, the crew aboard station is also working on more generalized studies of aging.

Jeff Williams: Record Breaker

Astronaut becomes U.S. record holder for most cumulative time in space!

The Olympics are over, but Americans are STILL breaking records. NASA astronaut Jeff Williams just broke Scott Kelly’s record of 520 cumulative days spent in space. When Williams returns to Earth on Sept. 5, he will have racked up 534 days in space. To celebrate this amazing achievement, here are some of the best images taken during his four spaceflights.

STS-101 Atlantis:

During May 2000, Williams made his first spacewalk during space shuttle Atlantis’ STS-101 mission. On this 10-day mission, Williams’ first spacewalk lasted nearly seven hours. He is pictured here outside the space station.

Expedition 13:

Williams experienced his first long-duration mission in 2006, when he served as flight engineer for Expedition 13 space station mission. During his time in orbit, he performed two spacewalks, saw the arrival of two space shuttle missions and resumed construction of the orbiting laboratory during his six-month tour. While on one of those spacewalks, Williams took this selfie.

Expedition 21/22:

Williams returned to space for another six-month mission in 2009 as a flight engineer on Expedition 21 and commander of Expedition 22. During that time, he hosted the crews of two space shuttle missions. The U.S.-built Tranquility module and cupola were installed on station. Here is an image of the then newly installed cupola.

Expedition 47/48:

This time around, Williams has been onboard the space station since March 2016, where he served as flight engineer for Expedition 47 and now commands Expedition 48. With over 7,000 retweets on Williams’ photo of an aurora from space, his Twitter followers were clearly impressed with his photography skills.

Five Things to Know About NASA Astronaut Kate Rubins

Among the newest crew on the International Space Station is U.S. astronaut Kate Rubins, who will assume the role of Flight Engineer for Expeditions 48 and 49. Here are five things you should know about her:

1. She was chosen from a pool of over 3,500 applicants to receive a spot on our 2009 astronaut training class.

After being selected, Rubins spent years training at Johnson Space Center to become an astronaut. She learned how to use the complex station systems, perform spacewalks, exercise in space and more. Some training even utilized virtual reality.

2. She has a degree in cancer biology.

After earning a Bachelor of Science degree in Molecular Biology from the University of California, San Diego in 1999, Rubins went on to receive a doctorate in Cancer Biology from Stanford University Medical School Biochemistry Department and Microbiology and Immunology Department in 2005. In other words, she’s extremely smart.

3. Her research has benefited humanity.

Rubins helped to create therapies for Ebola and Lassa viruses by conducting research collaboratively with the U.S. Army. She also aided development of the first smallpox infection model with the U.S. Army Medical Research Institute of Infectious Diseases and the Centers for Disease Control and Prevention. NBD. It will be exciting to see the research come out of a mission with a world-class scientist using a world-class, out-of-this-world laboratory!

4. She is scheduled to be the first person to sequence DNA in space.

During her time at the space station, Rubins will participate in several science experiments. Along with physical science, Earth and space science and technology development work, she will conduct biological and human research investigations. Research into sequencing the first genome in microgravity and how the human body’s bone mass and cardiovascular systems are changed by living in space are just two examples of the many experiments in which Rubins may take part.

5. In her spare time, she enjoys scuba diving and triathlons...among other things.

Rubins was on the Stanford Triathlon team, and also races sprint and Olympic distance. She is involved with health care/medical supply delivery to Africa and started a non-profit organization to bring supplies to Congo. Her recent pursuits involve flying airplanes and jumping out of them -- not simultaneously. 

Rubins is scheduled to arrive at the International Space Station at 12:12 a.m. Saturday, July 9. After her launch on Wednesday, July 6, the three crew members traveled 2 days before docking to the space station’s Rassvet module. 

Watch live coverage of docking and their welcoming starting at 11:30 p.m. EDT Friday, July 8 on NASA Television.

Twins Study Reddit AMA

Our Human Research Program is conducting a Twins Study on retired twin astronauts Scott and Mark Kelly. The study began during Scott Kelly’s One-Year Mission, which encompassed International Space Station Expeditions 43, 44, 45 and 46. 

Now that Scott has returned from space, researchers are integrating data as well as taking measurements on Earth from the twins. This is the first time we have conducted Omics research on identical twins. Omics is a broad area of biological and molecular studies that, in general, means the study of the entire complement of biomolecules, like proteins; metabolites or genes. 

Comparing various types of molecular information on identical individuals while one undergoes unique stresses, follows a defined diet, and resides in microgravity to one who resides on Earth, with gravity, should yield interesting results. It is hoped one day that all individuals will have access to having their Omics profiles done. This is a first step towards personalizing medicine for astronauts and hopefully for the rest of us. 

For background, check out NASA’s Omics video series at https://www.nasa.gov/twins-study.

During this Reddit AMA, you can ask our researchers anything about the Twins Study and Omics.

Houston, We Have a Launch!

Today, three new crew members will launch to the International Space Station. NASA astronaut Jeff Williams, along with Russian cosmonauts Alexey Ovchinin and Oleg Skripochka, are scheduled to launch from the Baikonur Cosmodrome in Kazakhstan at 5:26 p.m. EDT. The three Expedition 47 crew members will travel in a Soyuz spacecraft, rendezvousing with the space station six hours after launch.

Traveling to the International Space Station is an exciting moment for any astronaut. But what if you we’re launching to orbit AND knew that you were going to break some awesome records while you were up there? This is exactly what’s happening for astronaut Jeff Williams.

This is a significant mission for Williams, as he will become the new American record holder for cumulative days in space (with 534) during his six months on orbit. The current record holder is astronaut Scott Kelly, who just wrapped up his one-year mission on March 1.

On June 4, Williams will take command of the station for Expedition 48. This will mark his third space station expedition…which is yet another record!

What Did Astronaut Scott Kelly Do After a #YearInSpace?

Astronaut Scott Kelly just returned from his One-Year Mission aboard the International Space Station. After spending 340 days on orbit, you can imagine that he started to miss a few Earthly activities. Here are a few things he did after his return home:

While on the International Space Station for his One-Year Mission, astronaut Scott Kelly saw 16 sunrises/sunsets each day...so he definitely didn’t miss out on the beauty. That said, watching a sunset while on Earth is something that he had to wait to see. Tweet available HERE. 

Ate Fresh Food

After spending a year on the International Space Station, eating precooked food, anyone would be excited to dig into a REAL salad. Astronaut Scott Kelly was no exception, and posted about his first salad on Earth after his one-year mission. Learn more about what astronauts eat while in space HERE. Tweet available HERE.

Jumped into a Pool

Water is a precious resource in space. Unfortunately, that means that there isn’t a pool on the space station. Luckily, astronaut Scott Kelly was able to jump into some water after his return to Earth. Tweet/video available HERE.

Sat at a Dinner Table

While living on the International Space Station, crew members regularly enjoy their meals together, but do so while floating in microgravity. The comfort of pulling up a chair to the dinner table is something they can only experience once they’re back home on Earth. Tweet available HERE.

Enjoyed the Weather

When crew members live on the space station they can’t just step outside for a stroll. The only time they go outside the orbiting laboratory is during a spacewalk. Even then, they are confined inside a bulky spacesuit. Experiencing the cool breeze or drops of rain are Earthly luxuries. Tweet available HERE.

Stopped by the Doctor’s Office

The One-Year Mission doesn’t stop now that astronaut Scott Kelly is back on Earth. Follow-up exams and tests will help scientists understand the impacts of microgravity on the human body during long-duration spaceflight. This research will help us on our journey to Mars. Tweet available HERE. 

Visited the Denist

When you spend a year in space, you’ll probably need to catch up on certain things when you return to Earth. Astronaut Scott Kelly made sure to include a visit to the dentist on his “return home checklist”. Tweet available HERE.

Record Number of Americans Apply to #BeAnAstronaut

On Dec. 14, 2015, we announced that astronaut applications were open on USAJOBS. The window for applications closed on Feb. 18. We’re happy to announce that we have received more than 18,300 applications from excited individuals from around the country, all hoping to join the 2017 astronaut class. This surpasses the more than 6,100 received in 2012 for the most recent astronaut class, and the previous record - 8,000 applicants in 1978. 

So you applied to be an astronaut...now what?

Since the applications closed on Feb. 18, many people are curious to know…what’s next? Let us help you navigate the selection process:

Now that we have received all the applications, we will review them to determine the “Highly Qualified” applicants. This process will take place through summer 2016.

What is a “Highly Qualified” Applicant?

The diversity of experiences is what separates the highly qualified from qualified. Experience that demonstrates good leadership, fellowship and decision making are beneficial.

Between fall 2016 and spring 2017, interviewees will be brought to Johnson Space Center for evaluation. This process will help us determine the finalists, which takes place in spring 2017. 

Finally, in summer 2017, the Astronaut Candidate Class of 2017 is announced! These candidates will report to Johnson Space Center starting in August 2017. 

To view the full astronaut candidate selection process timeline, visit: http://astronauts.nasa.gov/content/timeline.htm

*Note that the high volume of applications received, dates in the timeline could be adjusted. 

Why do we need more astronauts?

We are continuing human spaceflight on the International Space Station, which has a continuous crew of six people on board. The Boeing and SpaceX commercial crew spacecraft that will travel to the station both have seats for four astronauts (the current Soyuz spacecraft, on which astronauts travel, only has three). This will add a seventh astronaut to the orbiting laboratory, and enable us to do more science!

How many astronauts will be selected?

The exact number will be determined by mission requirements, but current analysis shows about 8 - 14 astronauts will be needed. The final number will depend on updates to program plans, budgets, etc.

What You Didn’t Know About Scott Kelly and Living in Space (Floating Urine is Involved)

First Ever NASA Reddit AMA from Space Recap

NASA astronaut Scott Kelly hosted a Reddit Ask Me Anything on Jan. 23 where people, well, asked him anything.

Kelly answered a range of questions from whether the crew members play space pranks on one another ("Occasionally…" Kelly said without elaboration.) to whether Kelly's recovery plan will be different than normal ("I think my rehab plan is the same as if I were here for 6 months, but I'm not positive.").

To start off, here are a few quick facts we learned about Kelly during the AMA:

The advice he would've given himself before going into space on day 1 would be to pack lighter.

His favorite David Bowie song is "Modern Love," and his favorite non-space related movie is "The Godfather." 

He uses a Nikon D4 when taking pictures (camera settings and lenses vary).

He thought it was cool to watch the movie "Gravity" while he was on the space station, because that's where the movie took place.

Once he lands, Kelly will miss the challenge of being aboard the space station the most.

Here are a few fun questions that astronaut Scott Kelly answered:

What’s the creepiest thing you’ve encountered while on the job?

Could a rogue spaceship sneak up on the space station?

We finally got an answer for one thing so many of you have been curious about…why does Scott Kelly always fold his arms?

When astronauts go up to space, they experience something very few others have and see Earth from a very unique perspective. What’s one thing Kelly will do differently once he returns home?

Kelly also told one user something unusual about being in space that people normally don’t think about: feet calluses.

Another user wanted to know what the largest societal misconception about space/space travel is. According to Kelly, it has nothing to do with science.

To read the entire Reddit AMA with Kelly, visit his IAmA thread.

Kelly's #YearInSpace ends Mar. 2. Follow him until the end of the journey (and beyond) on Twitter, Instagram and Facebook.

5 Signs You Might Be Ready to Apply to be an Astronaut

Did you hear? Astronaut applications are open! Here are a few signs that might mean you’re ready to apply:

1. You Don’t Mind Having Roommates

When you’re an astronaut, you have to work and live with your crew mates for extended periods of time. It’s important to the mission and your safety that everyone can collaborate and work together.

2. You LOVE Space

If the Milky Way, planets and space travel doesn’t excite you then this might not be the perfect job for you. But if you love galaxies, space station research and deep space exploration, then maybe you should take a look at our application.

3. Adventure Doesn’t Scare You

Being an astronaut means that you get to take part in adventures that most people will never experience. Imagine: sitting on the launch pad in the Orion spacecraft, atop a rocket that’s getting ready to launch. You’ll travel farther into space than any other humans have been and help push the boundaries of technology in the proving ground of deep space lunar orbits, leading the way for future missions to Mars.

4. You Want to be on the Cutting Edge of Science

Not only do astronauts get to travel to space, but they also get to conduct really cool research in microgravity. Did you know that right now they’re growing Zinnia flowers on the International Space Station? This research could help with our future deep space exploration and could teach us a few things about growing plants on Earth. Learn more about all the awesome research on the space station HERE.

5. You’re Not Afraid of Heights

One of the coolest things about being an astronaut, is that you get to go to SPACE! At the very least, you’ll travel to the International Space Station, which is 250 miles above Earth. Or, you could be one of the first astronauts to travel to a distant asteroid or even Mars!

Interested in applying to become an astronaut? You’re in luck, applications open Dec. 14! Learn about some common myths about becoming an astronaut HERE.

5 Myths About Becoming an Astronaut

Editor’s Note: This post was updated on March 15, 2024, to reflect new URLs and updated qualifications for applicants.

Have you ever wondered if you have what it takes to become a NASA astronaut? The term “astronaut” derives from the Greek word meaning “star sailor.”

We’re looking for a new class of astronauts to join the NASA team, and if you’re thinking about applying, there are a few things you should know.

Here are a few myths about becoming an astronaut:

MYTH: All astronauts have piloting experience.

FACT: You don’t need to be a pilot to be an astronaut. Flying experience is not a requirement, but it could be beneficial to have.

MYTH: All astronauts have perfect vision.

FACT: It’s OK if you don’t have 20/20 vision. As of September 2007, corrective surgical procedures of the eye (PRK and LASIK), are now allowed, providing at least one year has passed since the date of the procedure with no permanent adverse aftereffects.

MYTH: All astronauts have advanced degrees, like a PhD.

FACT: While a master’s degree from an accredited university is typically necessary to become an astronaut, an exception exists if you have completed a medical degree or test pilot school.

MYTH: Astronauts are required to have military experience to be selected.

FACT: Military experience is not required to become an astronaut.

MYTH: You must be a certain age to be an astronaut. 

FACT: There are no age restrictions. Astronaut candidates selected in the past have ranged between the ages of 26 and 46, with the average age being 34.

OK, but what are the requirements?

Basic Qualification Requirements

Applicants must meet the following minimum requirements before submitting an application:

Be a U.S. citizen.

Have completed a master’s degree (or foreign equivalent) in an accredited college or university with major study in an appropriate technical field of engineering, biological science, physical science, computer science, or mathematics.

The master’s degree requirement can also be met by having:

Completed at least two years (36 semester hours or 54 quarter hours) in an accredited PhD or related doctoral degree program (or foreign equivalent) with major study in an appropriate technical field of engineering, biological science, physical science, computer science, or mathematics.

Completed a Doctor of Medicine, Doctor of Osteopathic Medicine, or related medical degree (or foreign equivalent) in an accredited college or university.

Completed or be currently enrolled in a Test Pilot School (TPS) program (nationally or internationally recognized) and will have completed this program by June 2025. (Must submit proof of completion or enrollment.)

If TPS is your only advanced technical degree, you must have also completed a bachelor’s degree or higher (or foreign equivalent) at an accredited college or university with major study in an appropriate technical field of engineering, biological science, physical science, computer science, or mathematics.

Have at least three years of related professional experience obtained after degree completion (or 1,000 Pilot-in-Command hours with at least 850 of those hours in high-performance jet aircraft for pilots). For medical doctors, time in residency can count toward experience and must be completed by June 2025.

Be able to pass the NASA long-duration flight astronaut physical.

Applications for our next astronaut class are open through April 16! Learn more about our Astronaut Selection Program and check out current NASA astronaut Anne McClain’s advice in “An Astronaut’s Guide to Applying to Be an Astronaut.”
