Athletes Go for the Gold with NASA Spinoffs

NASA technology tends to find its way into the sporting world more often than you’d expect. Fitness is important to the space program because astronauts must undergo the extreme g-forces of getting into space and endure the long-term effects of weightlessness on the human body. The agency’s engineering expertise also means that items like shoes and swimsuits can be improved with NASA know-how.

As the 2024 Olympics are in full swing in Paris, here are some of the many NASA-derived technologies that have helped competitive athletes train for the games and made sure they’re properly equipped to win.

The LZR Racer reduces skin friction drag by covering more skin than traditional swimsuits. Multiple pieces of the water-resistant and extremely lightweight LZR Pulse fabric connect at ultrasonically welded seams and incorporate extremely low-profile zippers to keep viscous drag to a minimum.

Swimsuits That Don’t Drag

When the swimsuit manufacturer Speedo wanted its LZR Racer suit to have as little drag as possible, the company turned to the experts at Langley Research Center to test its materials and design. The end result was that the new suit reduced drag by 24 percent compared to the prior generation of Speedo racing suit and broke 13 world records in 2008. While the original LZR Racer is no longer used in competition due to the advantage it gave wearers, its legacy lives on in derivatives still produced to this day.

Trilion Quality Systems worked with NASA’s Glenn Research Center to adapt existing stereo photogrammetry software to work with high-speed cameras. Now the company sells the package widely, and it is used to analyze stress and strain in everything from knee implants to running shoes and more.

High-Speed Cameras for High-Speed Shoes

After space shuttle Columbia, investigators needed to see how materials reacted during recreation tests with high-speed cameras, which involved working with industry to create a system that could analyze footage filmed at 30,000 frames per second. Engineers at Adidas used this system to analyze the behavior of Olympic marathoners' feet as they hit the ground and adjusted the design of the company’s high-performance footwear based on these observations.

Martial artist Barry French holds an Impax Body Shield while former European middle-weight kickboxing champion Daryl Tyler delivers an explosive jump side kick; the force of the impact is registered precisely and shown on the display panel of the electronic box French is wearing on his belt.

One-Thousandth-of-an-Inch Punch

In the 1980s, Olympic martial artists needed a way to measure the impact of their strikes to improve training for competition. Impulse Technology reached out to Glenn Research Center to create the Impax sensor, an ultra-thin film sensor which creates a small amount of voltage when struck. The more force applied, the more voltage it generates, enabling a computerized display to show how powerful a punch or kick was.

Astronaut Sunita Williams poses while using the Interim Resistive Exercise Device on the ISS. The cylinders at the base of each side house the SpiraFlex FlexPacks that inventor Paul Francis honed under NASA contracts. They would go on to power the Bowflex Revolution and other commercial exercise equipment.

Weight Training Without the Weight

Astronauts spending long periods of time in space needed a way to maintain muscle mass without the effect of gravity, but lifting free weights doesn’t work when you’re practically weightless. An exercise machine that uses elastic resistance to provide the same benefits as weightlifting went to the space station in the year 2000. That resistance technology was commercialized into the Bowflex Revolution home exercise equipment shortly afterwards.

It’s Girl Scout Day! March 12, 2024, is the 112th birthday of Girl Scouts in the United States, and to celebrate, we’re sharing a lithograph of the Girl Scout alumnae who became NASA astronauts.

Girl Scouts learn to work together, build community, embrace adventurousness and curiosity, and develop leadership skills—all of which come in handy as an astronaut. For example, former Scouts Christina Koch and Jessica Meir worked together to make history on Oct. 18, 2019, when they performed the first all-woman spacewalk.

Pam Melroy is one of only two women to command a space shuttle and became NASA’s deputy administrator on June 21, 2021.

Nicole Mann was the first Indigenous woman from NASA to go to space when she launched to the International Space Station on Oct. 5, 2022. Currently, Loral O’Hara is aboard the space station, conducting science experiments and research.

Participating in thoughtful activities in leadership and STEM in Girl Scouts has empowered and inspired generations of girls to explore space, and we can’t wait to meet the future generations who will venture to the Moon and beyond.

As we celebrate 20 years of humans living and working on the International Space Station, we’re also getting ready for another space milestone: Crew-1, this weekend’s trip to the ISS aboard the SpaceX Crew Dragon Resilience and the first certified crew rotation flight to the International Space Station.

Crew-1 is scheduled to lift off Saturday at 7:49 PM EST, from our Kennedy Space Center—but across the United States, teams from NASA and SpaceX will be hard at work sending our astronauts into orbit!

Image Credit: NASA/Fred Deaton

At Marshall Space Flight Center’s Huntsville Operations Support Center (HOSC), for example, engineers with our Commercial Crew Program have been helping review the design and oversee safety standards for SpaceX’s Falcon 9 rocket, making sure it’s ready to carry humans to the Space Station.

This Saturday, they’ll be in the HOSC to monitor launch conditions and watch the data as Crew-1 blasts off, helping future commercially-operated missions to the ISS run even more smoothly.

Long before Crew-1, though, Marshall has been keeping things active on board the ISS. For decades, the Payload Operations and Integration Center, also located in the HOSC, has been “science central” for the Space Station, coordinating and keeping track of the scientific experiments taking place—24/7, 365 days a year.

With the Space Station’s population soon to jump from three to seven, our ISS crew will be able to spend up to 70 hours a week on science, helping us learn how to live in space while making life better on Earth!

Tomorrow’s Technology on the Space Station Today

Tablets, smart appliances, and other technologies that are an indispensable part of daily life are no longer state-of-the-art compared to the research and technology development going on over our heads. As we celebrate 20 years of humans continuously living and working in space aboard the International Space Station, we’re recapping some of the out-of-this-world tech development and research being done on the orbiting lab too.

Our Space Technology Mission Directorate (STMD) helps redefine state-of-the-art tech for living and working in space. Here are 10 technologies tried and tested on the space station with helping hands from its astronaut occupants over the years.

1. Astronaut Wanna-Bees

Astronauts on the space station are responsible for everything from conducting science experiments and deploying satellites to tracking inventory and cleaning. While all are necessary, the crew can delegate some jobs to the newest robotic inhabitants – Astrobees.

These cube-shaped robots can work independently or in tandem, carrying out research activities. Once they prove themselves, the bots will take on some of the more time-consuming tasks, such as monitoring the status of dozens of experiments. The three robots – named Bumble, Honey, and Queen – can operate autonomously following a programmed set of instructions or controlled remotely. Each uses cameras for navigation, fans for propulsion, and a rechargeable battery for power. The robots also have a perching arm that lets them grip handrails or hold items. These free-flying helpers take advantage of another STMD technology called Gecko Grippers that “stick” to any surface.

2. Getting a Grip in Microgravity

We wanted to develop tools for grabbing space junk, and something strong and super-sticky is necessary to collect the diverse material orbiting Earth. So, engineers studied the gecko lizard, perhaps the most efficient “grabber” on this planet. Millions of extremely fine hairs on the bottom of their feet make an incredible amount of contact with surfaces so the gecko can hold onto anything. That inspired our engineers to create a similar material.

Now the Gecko Gripper made by OnRobot is sold on the commercial market, supporting industrial activities such as materials handling and assembly. The NASA gecko adhesive gripper that’s being tested in microgravity on the Astrobee robots was fabricated on Earth. But other small plastic parts can now be manufactured in space.

3. Make It, or Don’t Take It

Frequent resupply trips from Earth to the Moon, Mars, and other solar system bodies are simply not realistic. In order to become truly Earth-independent and increase sustainability, we had to come up with ways to manufacture supplies on demand.

A demonstration of the first 3D printer in space was tested on the space station in 2014, proving it worked in microgravity. This paved the way for the first commercial 3D printer in space, which is operated by Made In Space. It has successfully produced more than 150 parts since its activation in 2016. Designs for tools, parts, and many other objects are transmitted to the station by the company, which also oversees the print jobs. Different kinds of plastic filaments use heat and pressure in a process that’s similar to the way a hot glue gun works. The molten material is precisely deposited using a back-and-forth motion until the part forms. The next logical step for efficient 3D printing was using recycled plastics to create needed objects.

4. The Nine Lives of Plastic

To help fragile technology survive launch and keep food safe for consumption, NASA employs a lot of single-use plastics. That material is a valuable resource, so we are developing a number of ways to repurpose it. The Refabricator, delivered to the station in 2018, is designed to reuse everything from plastic bags to packing foam. The waste plastic is super-heated and transformed into the feedstock for its built-in 3D printer. The filament can be used repeatedly: a 3D-printed wrench that’s no longer needed can be dropped into the machine and used to make any one of the pre-programmed objects, such as a spoon. The dorm-fridge-sized machine created by Tethers Unlimited Inc. successfully manufactured its first object, but the technology experienced some issues in the bonding process likely due to microgravity’s effect on the materials. Thus, the Refabricator continues to undergo additional testing to perfect its performance.

5. Speed Metal

An upcoming hardware test on the station will try out a new kind of 3D printer. The on-demand digital manufacturing technology is capable of using different kinds of materials, including plastic and metals, to create new parts. We commissioned TechShot Inc. to build the hardware to fabricate objects made from aerospace-grade metals and electronics. On Earth, FabLab has already demonstrated its ability to manufacture strong, complex metal tools and other items. The unit includes a metal additive manufacturing process, furnace, and endmill for post-processing. It also has built-in monitoring for in-process inspection. When the FabLab is installed on the space station, it will be remotely operated by controllers on Earth. Right now, another printer created by the same company is doing a different kind of 3D printing on station.

6. A Doctor’s BFF

Today scientists are also learning to 3D print living tissues. However, the force of gravity on this planet makes it hard to print cells that maintain their shape. So on Earth, scientists use scaffolding to help keep the printed structures from collapsing.

The 3D BioFabrication Facility (BFF) created by TechShot Inc. could provide researchers a gamechanger that sidesteps the need to use scaffolds by bioprinting in microgravity. This first American bioprinter in space uses bio-inks that contain adult human cells along with a cell-culturing system to strengthen the tissue over time. Eventually, that means that these manufactured tissues will keep their shape once returned to Earth’s gravity! While the road to bioprinting human organs is likely still many years away, these efforts on the space station may move us closer to that much-needed capability for the more than 100,000 people on the wait list for organ transplant.

7. Growing Vitamins

Conditions in space are hard on the human body, and they also can be punishing on food. Regular deliveries of food to the space station refresh the supply of nutritious meals for astronauts. But prepackaged food stored on the Moon or sent to Mars in advance of astronauts could lose some nutritional value over time.

That’s why the BioNutrients experiment is underway. Two different strains of baker’s yeast which are engineered to produce essential nutrients on demand are being checked for shelf life in orbit. Samples of the yeast are being stored at room temperature aboard the space station and then are activated at different intervals, frozen, and returned to Earth for evaluation. These tests will allow scientists to check how long their specially-engineered microbes can be stored on the shelf, while still supplying fresh nutrients that humans need to stay healthy in space. Such microbes must be able to be stored for months, even years, to support the longer durations of exploration missions. If successful, these space-adapted organisms could also be engineered for the potential production of medicines. Similar organisms used in this system could provide fresh foods like yogurt or kefir on demand. Although designed for space, this system also could help provide nutrition for people in remote areas of our planet.

8. Rough and Ready

Everything from paints and container seals to switches and thermal protection systems must withstand the punishing environment of space. Atomic oxygen, charged-particle radiation, collisions with meteoroids and space debris, and temperature extremes (all combined with the vacuum) are just some conditions that are only found in space. Not all of these can be replicated on Earth. In 2001, we addressed this testing problem with the Materials International Space Station Experiment (MISSE). Technologists can send small samples of just about any technology or material into low-Earth orbit for six months or more. Mounted to the exterior of the space station, MISSE has tested more than 4,000 materials. More sophisticated hardware developed over time now supports automatic monitoring that sends photos and data back to researchers on Earth. Renamed the MISSE Flight Facility, this permanent external platform is now owned and operated by the small business, Alpha Space Test & Research Alliance LLC. The woman-owned company is developing two similar platforms for testing materials and technologies on the lunar surface.

9. Parachuting to Earth

Small satellites could provide a cheaper, faster way to deliver small payloads to Earth from the space station. To do just that, the Technology Education Satellite, or TechEdSat, develops the essential technologies with a series of CubeSats built by college students in partnership with NASA. In 2017, TechEdSat-6 deployed from the station, equipped with a custom-built parachute called exo-brake to see if a controlled de-orbit was possible. After popping out of the back of the CubeSat, struts and flexible cords warped the parachute like a wing to control the direction in which it travelled. The exo-brake uses atmospheric drag to steer a small satellite toward a designated landing site. The most recent mission in the series, TechEdSat-10, was deployed from the station in July with an improved version of an exo-brake. The CubeSat is actively being navigated to the target entry point in the vicinity of the NASA’s Wallops Flight Facility on Wallops Island, Virginia.

10. X-ray Vision for a Galactic Position System

Independent navigation for spacecraft in deep space is challenging because objects move rapidly and the distances between are measured in millions of miles, not the mere thousands of miles we’re used to on Earth. From a mission perched on the outside of the station, we were able to prove that X-rays from pulsars could be helpful. A number of spinning neutron stars consistently emit pulsating beams of X-rays, like the rotating beacon of a lighthouse. Because the rapid pulsations of light are extremely regular, they can provide the precise timing required to measure distances.

The Station Explorer for X-Ray Timing and Navigation (SEXTANT) demonstration conducted on the space station in 2017 successfully measured pulsar data and used navigation algorithms to locate the station as it moved in its orbit. The washing machine-sized hardware, which also produced new neutron star science via the Neutron star Interior Composition Explorer (NICER), can now be miniaturized to develop detectors and other hardware to make pulsar-based navigation available for use on future spacecraft.

As NASA continues to identify challenges and problems for upcoming deep space missions such as Artemis, human on Mars, and exploring distant moons such as Titan, STMD will continue to further technology development on the space station and Earth.

How is Biotechnology Preparing us to Live on the Moon and Mars?

The adventures awaiting astronauts on future long-duration missions have technologists researching sustainable ways to live away from Earth. We’re using what we know from almost 20 years of a continuous human presence on the International Space Station and looking at new technologies to prepare for missions to the Moon and Mars. 

Biotechnology – technology that uses living organisms to make products that provide a new use – is key to this research.

With biotechnology, we’re developing new ways to manufacture medicines, build habitats and more in space. Here are some ways biotechnology is advancing spaceflight and how the same research is reaping benefits on Earth.

Healthy astronauts

Planning ways to supply food for a multi-year mission on the Moon or Mars may require making food and nutrients in space. Our scientists are testing an early version of a potential solution: get microorganisms to produce vital nutrients like those usually found in vegetables. Then, whenever they’re needed, astronauts can drink them down. 

The microorganisms are genetically engineered to rapidly produce controlled quantities of essential nutrients. Because the microorganisms and their food source both have a long shelf-life at room temperature and only need water to be activated, the system provides a simple, practical way to produce essential nutrients on-demand. The same kind of system designed for space could also help provide nutrition for people in remote areas of our planet.

Our researchers are evaluating the first batches of BioNutrient samples that came back to Earth after an experimental run on the International Space Station.

Because space travel takes a toll on the human body, we’re also researching how biotechnology can be used to advance the field of regenerative medicine. 

Related cells that are joined together are collectively referred to as tissue, and these cells work together as organs to accomplish specific functions in the human body. Blood vessels around the cells vascularize, providing nutrients to the tissue to keep it healthy. 

Our Vascular Tissue Challenge offers a $500,000 prize to be divided among the first three teams that successfully create thick, metabolically-functional human vascularized organ tissue in a controlled laboratory environment. The vascularized, thick-tissue models resulting from this challenge will function as organ analogs, or models, that can be used to study deep space environmental effects, such as radiation, and to develop strategies to minimize the damage to healthy cells.  

Plant factories

Humans have relied on plants’ medicinal qualities for thousands of years for everything from alleviating minor ailments to curing serious diseases. Now, researchers are trying to simplify the process of turning plants into medicine (i.e. how to make it compact and portable). If successful, the cost of biomanufacturing pharmaceuticals on Earth could go down, and plants could produce medicines in space.

Creating medicine on demand isn’t something we typically do, so we’re turning to experts in the field for help. Researchers at the University of California, Davis are transforming plants into mini-medicine factories for future Mars missions. They’re genetically altering an ordinary type of lettuce so that it produces a protein called parathyroid hormone. This hormone is an approved drug for treating osteoporosis, a common condition where bones become weak and brittle.

This type of research is important to long duration spaceflight. When astronauts land on Mars, they will have spent more than half a year in zero gravity on the flight there, and they’ll need to be strong and ready to explore. Having the technologies needed to treat that possibility, and other unanticipated health effects of long duration spaceflight, is crucial.

Growing habitats

Vitamins aren’t the only thing astronauts could be growing on Mars; we’re exploring technologies that could grow structures out of fungi.

An early-stage research project underway at our Ames Research Center is prototyping technologies that could "grow" habitats on the Moon, Mars and beyond out of life – specifically, fungi and the unseen underground threads that make up the main part of the fungus. These tiny threads build complex structures with extreme precision, networking out into larger structures like mushrooms. With the right conditions, they can be coaxed into making new structures – ranging from a material similar to leather to the building blocks for a planetary home.

The myco-architecture project envisions a future where astronauts can construct a habitat out of the lightweight fungi material. Upon arrival, by unfolding a basic structure made up of dormant fungi and simply adding water, the fungi would grow around that framework into a fully functional human habitat – all while being safely contained to avoid contaminating the external environment.

Recycling waste

Once astronauts arrive on the surface of the Moon or a more distant planet, they’ll have to carefully manage garbage. This waste includes some stuff that gets flushed on Earth.

Today, we’re already using a recycling system on the space station to turn urine into drinking water. Poop on the other hand is contained then disposed of on spacecraft returning to Earth. That won’t be possible on more distant journeys, so, we’re turning to biomanufacturing for a practical solution.

Biology can serve as an effective recycling factory. Microorganisms such as yeast and algae feed on all kinds of things classified as “mission waste.” Processing their preferred form of nourishment generates products that can serve as raw materials used to make essential supplies like nutrients, medicines, plastic and fuel.

By taking a careful look at biological processes, we hope to develop new, lightweight systems to leverage that biology to do some helpful in-space manufacturing.

From Space to Earth

Biotechnology is preparing us for longer space missions to the Moon and then Mars – farther from Earth than humans have ever traveled before. As we prepare for those exciting missions, we’re also conducting research on the space station for the primary benefit of everyone on Earth.

January is National Biotechnology Month. To learn more about some of the ways NASA is using biotechnology to solve challenges in space and improve life on Earth, visit this link.

SPACE: A Global Frontier

Space is a global frontier. That’s why we partner with nations all around the world to further the advancement of science and to push the boundaries of human exploration. With international collaboration, we have sent space telescopes to observe distant galaxies, established a sustainable, orbiting laboratory 254 miles above our planet’s surface and more! As we look forward to the next giant leaps in space exploration with our Artemis lunar exploration program, we will continue to go forth with international partnerships!

Teamwork makes the dream work. Here are a few of our notable collaborations:

Artemis Program

Our Artemis lunar exploration program will send the first woman and the next man to the Moon by 2024. Using innovative technologies and international partnerships, we will explore more of the lunar surface than ever before and establish sustainable missions by 2028.

During these missions, the Orion spacecraft will serve as the exploration vehicle that will carry the crew to space, provide emergency abort capability and provide safe re-entry from deep space return velocities. The European Service Module, provided by the European Space Agency, will serve as the spacecraft’s powerhouse and supply it with electricity, propulsion, thermal control, air and water in space.

The Gateway, a small spaceship that will orbit the Moon, will be a home base for astronauts to maintain frequent and sustainable crewed missions to the lunar surface. With the help of a coalition of nations, this new spaceship will be assembled in space and built within the next decade.

Gateway already has far-reaching international support, with 14 space agencies agreeing on its importance in expanding humanity's presence on the Moon, Mars and deeper into the solar system.

International Space Station

The International Space Station (ISS) is one of the most ambitious international collaborations ever attempted. Launched in 1998 and involving the U.S., Russia, Canada, Japan and the participating countries of the European Space Agency — the ISS has been the epitome of global cooperation for the benefit of humankind. The largest space station ever constructed, the orbital laboratory continues to bring together international flight crews, globally distributed launches, operations, training, engineering and the world’s scientific research community.

Hubble Space Telescope 

The Hubble Space Telescope, one of our greatest windows into worlds light-years away, was built with contributions from the European Space Agency (ESA).

ESA provided the original Faint Object Camera and solar panels, and continues to provide science operations support for the telescope. 

Deep Space Network

The Deep Space Network (DSN) is an international array of giant radio antennas that span the world, with stations in the United States, Australia and Spain. The three facilities are equidistant approximately one-third of the way around the world from one another – to permit constant communication with spacecraft as our planet rotates. The network supports interplanetary spacecraft missions and a few that orbit Earth. It also provides radar and radio astronomy observations that improve our understanding of the solar system and the larger universe!

Mars Missions 

Information gathered today by robots on Mars will help get humans to the Red Planet in the not-too-distant future. Many of our Martian rovers – both past, present and future – are the products of a coalition of science teams distributed around the globe. Here are a few notable ones:

Curiosity Mars Rover 

France: ChemCam, the rover’s laser instrument that can analyze rocks from more than 20 feet away

Russia: DAN, which looks for subsurface water and water locked in minerals

Spain: REMS, the rover’s weather station

InSight Mars Lander

France with contributions from Switzerland: SEIS, the first seismometer on the surface of another planet

Germany: HP3, the heatflow probe that will help us understand the interior structure of Mars

Spain: APSS, the lander’s weather station

Mars 2020 Rover

Norway: RIMFAX, a ground-penetrating radar

France: SuperCam, the laser instrument for remote science

Spain: MEDA, the rover’s weather station

Space-Analog Astronaut Training

We partner with space agencies around the globe on space-analog missions. Analog missions are field tests in locations that have physical similarities to the extreme space environments. They take astronauts to space-like environments to prepare as international teams for near-term and future exploration to asteroids, Mars and the Moon.

The European Space Agency hosts the Cooperative Adventure for Valuing and Exercising human behavior and performance Skills (CAVES) mission. The two week training prepares multicultural teams of astronauts to work safely and effectively in an environment where safety is critical. The mission is designed to foster skills such as communication, problem solving, decision-making and team dynamics.

We host our own analog mission, underwater! The NASA Extreme Environment Mission Operations (NEEMO) project sends international teams of astronauts, engineers and scientists to live in the world’s only undersea research station, Aquarius, for up to three weeks. Here, “aquanauts” as we call them, simulate living on a spacecraft and test spacewalk techniques for future space missions in hostile environments.

International Astronautical Congress 

So, whether we’re collaborating as a science team around the globe, or shoulder-to-shoulder on a spacewalk, we are committed to working together with international partners for the benefit of all humanity! 

If you’re interested in learning more about how the global space industry works together, check out our coverage of the 70th International Astronautical Congress (IAC) happening this week in Washington, D.C. IAC is a yearly gathering in which all space players meet to talk about the advancements and progress in exploration.

What has been the best memory you have so far at NASA?

What aspect of spaceflight always blows your mind, even after all this time?

What was the most fun you had in Mission Control?

... and we’re ‘GO’ for launch! 🚀

NASA Flight Integration Chief and past Mission Control Flight Director, Ginger Kerrick, is here answering your questions during this Tumblr Answer Time. Tune in and join the fun!

What's your opinion on astronaut food?

Is the earth really as beautiful as they say from space?

Hey! I was wondering how everyone on the ISS adjusts to each other’s culture and language. It seems like it might be hard with language barriers and other factors, to live in a confined space with people from another country. Do others try to teach you their language? Does everyone mostly speak English, or do some people speak Russian?

The Summer Solstice Has Arrived!

This year’s summer solstice for the northern hemisphere arrives at 11:54 a.m. EDT, meaning today is the longest day of the year! The number of daylight hours varies by latitude, so our headquarters in Washington, D.C. will see 14 hours, 53 minutes, and 51 seconds of daylight. A lot can happen in that time! Let’s find out more.

If you’re spending the day outside, you might be in the path of our Earth Science Satellite Fleet (ESSF)! The fleet, made up of over a dozen Earth observation satellites, will pass over the continental United States about 37 times during today’s daylight hours. 

These missions collect data on atmospheric chemistry and composition, cloud cover, ocean levels, climate, ecosystem dynamics, precipitation, and glacial movement, among other things. They aim to do everything from predicting extreme weather to helping informing the public and decision makers with the environment through GPS and imaging. Today, their sensors will send back over 200 gigabytes (GB) of data back to the ground by sunset. 

As the sun sets today, the International Space Station (ISS) will be completing its 10th orbit since sunrise. In that time, a little more than 1 terabyte-worth of data will be downlinked to Earth.

That number encompasses data from ground communications, payloads, experiments, and control and navigation signals for the station. Approximately 330 GB of that TB is video, including live broadcasts and downlinks with news outlets. But as recently-returned astronaut Serena Auñón-Chancellor likes to point out, there’s still room for fun. The astronauts aboard the ISS can request YouTube videos or movies for what she likes to call “family movie night.”

Astronauts aboard the station also send back images—LOTS of them. Last year, astronauts sent back an average of 66,912 images per month! During today’s long hours of daylight, we expect the crew to send back about 656 images. But with Expedition 59 astronauts David Saint-Jacques (CSA), Anne McClain (NASA), and Oleg Kononenko (RKA) hard at work preparing to return to Earth on Monday, that number might be a little less. 

Say you’re feeling left out after seeing the family dinners and want to join the crew. Would you have enough daylight to travel to the ISS and back on the longest day of the year? Yes, but only if you’re speedy enough, and plan your launch just right. With the current fastest launch-to-docking time of about six hours, you could complete two-and-a-half flights to the ISS today between sunrise and sunset.

When returning from orbit, it’s a longer ordeal. After the Expedition 59 trio arrives on Earth Monday night, they’ll have to travel from Kazakhstan to Houston to begin their post-flight activities. Their journey should take about 18 hours and 30 minutes, just a few hours longer than the hours of daylight we’ll see today.

Happy solstice! Make sure to tune in with us on Monday night for live coverage of the return of Expedition 59. Until then, enjoy the longest day of the year!

Spacewalk Reassignments: What’s the Deal?

On Friday, March 29, Christina Koch and Anne McClain were scheduled to perform a spacewalk together to upgrade the power systems of the International Space Station. It would have been the first all-female spacewalk in human history. While disappointing to many people, after the last spacewalk was completed on March 22, NASA changed the assignments to protect the safety of the crew and the timing of the mission. Now, Christina Koch and Nick Hague will be performing this upcoming spacewalk, leaving lots of people wondering: What’s the deal?

1. Why did the availability of spacesuit sizes affect the schedule?

Spacesuits are not “one size fits all.” We do our best to anticipate the spacesuit sizes each astronaut will need, based on the spacesuit size they wore in training on the ground, and in some cases astronauts train in multiple sizes.

McClain trained in both a medium and a large on Earth. However, living in microgravity can change the size of your body! In fact, Anne McClain has grown two inches since she launched to the Space Station.

McClain realized that the medium she wore during the March 22 spacewalk was a better fit for her in space. She had planned to wear a large during the March 29 spacewalk.

In a tweet, McClain explained: “This decision was based on my recommendation. Leaders must make tough calls, and I am fortunate to work with a team who trusts my judgement. We must never accept a risk that can instead be mitigated. Safety of the crew and execution of the mission come first.”

To provide each astronaut the best fitting spacesuit during their spacewalks, Koch will wear the medium torso on March 29, and McClain will wear it again on April 8.

2. Why is spacesuit sizing so important?

The spacesuit is a mini spaceship that keeps our astronauts alive while they are spacewalking!

Astronauts train several hours on Earth in the Neutral Buoyancy Lab for every hour they spend spacewalking. Spacewalks are the most physically demanding thing we ask astronauts to do, which is why an optimally fitted spacesuit is important to completing the assigned tasks and overall mission!

3. How come you don’t have enough spacesuits in the right size?

We do have enough torsos. The spacesuit takes into account more than 80 different body measurements to be configured for each astronaut. The suit has three sizes of upper torso, eight sizes of adjustable elbows, over 65 sizes of gloves, two sizes of adjustable waists, five sizes of adjustable knees and a vast array of padding options for almost every part of the body.

In space, we have two medium hard upper torsos, two larges and two extra larges; however, one of the mediums and one of the extra larges are spares that would require 12 hours of crew time for configuration.

Configuring the spare medium is a very methodical and meticulous process to ensure the intricate life support system — including the controls, seals, and hoses for the oxygen, water and power as well as the pressure garment components — are reassembled correctly with no chance of leaks. 

Nothing is more important than the safety of our crew!

12 hours might not seem like a long time, but the space station is on a very busy operational schedule. An astronaut's life in space is scheduled for activities in five minute increments. Their time is scheduled to conduct science experiments, maintain their spaceship and stay healthy (they exercise two hours a day to keep their bones and muscles strong!).

The teams don’t want to delay this spacewalk because two resupply spacecraft – Northrop Grumman Cygnus and SpaceX cargo Dragon – are scheduled to launch to the space station in the second half of April. That will keep the crew very busy for a while!

4. Why has there not already been an all-female spacewalk?

NASA does not make assignments based on gender.

The first female space shuttle commander, the first female space station commander and the first female spacewalker were all chosen because they the right individuals for the job, not because they were women. It is not unusual to change spacewalk assignments as lessons are learned during operations in space.

McClain became the 13th female spacewalker on March 22, and Koch will be the 14th this Friday – both coincidentally during Women’s History Month! Women also are filling two key roles in Mission Control: Mary Lawrence as the lead flight director and Jaclyn Kagey as the lead spacewalk officer.

5. When will the all-female spacewalk happen?

An all-female spacewalk is inevitable! As the percentage of women who have become astronauts increases, we look forward to celebrating the first spacewalk performed by two women! McClain, Koch (and Hague!) are all part of the first astronaut class that was 50 percent women, and five of the 11 members of the 2017 astronaut candidate class are also women.

You can watch the upcoming spacewalk on March 29 at 6:30 ET, which is one in a series to upgrade the station’s power technology with new batteries that store power from the solar arrays for the station to use when it is in orbital night.

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.

River Bends Through 1,000-Foot Canyons

An astronaut aboard the International Space Station shot this photograph of the Green River flowing through deep, red rock canyons in eastern Utah. A main tributary of the Colorado River, the Green flows 730 miles (1,175 kilometers) through Wyoming, Colorado and Utah. The portion of the Green River in this image is just north of Canyonlands National Park.

Bowknot Bend was named for the way the river loops back on itself. Located in Labyrinth Canyon about 25 miles west of Moab, Utah, this river bend runs 7.5 miles (12 kilometers) in a circular loop and ends up 1,200 feet (360 meters) from where it first started. When the two sides of the river merge someday, Bowknot Bend will break off from the main channel and form a lake.

AI, Cancer Therapy and Chemical Gardens Headed to Space Station

A new batch of science is headed to the International Space Station aboard the SpaceX Dragon on the company’s 15th mission for commercial resupply services. The spacecraft will deliver science that studies the use of artificial intelligence, plant water use all over the planet, gut health in space, more efficient drug development and the formation of inorganic structures without the influence of Earth’s gravity. 

Take a look at five investigations headed to space on the latest SpaceX resupply:

Plants regulate their temperature by releasing water through tiny pores on their leaves. If they have sufficient water they can maintain their temperature, but if water is insufficient their temperatures rise. This temperature rise can be measured with a sensor in space.

ECOSTRESS measures the temperature of plants and uses that information to better understand how much water plants need and how they respond to stress.

Spaceflight has an on impact many bodily systems. Rodent Research-7 takes a look at how the microgravity environment of space affects the community of microoganisms in the gastrointestinal tract, or microbiota.

The study also evaluates relationships between system changes, such as sleep-wake cycle disruption, and imbalance of microbial populations, to identify contributing factors and supporting development of countermeasures to protect astronaut health during long-term missions, as well as to improve the treatment of gastrointestinal, immune, metabolic and sleep disorders on Earth.

Cardiovascular diseases and cancer are the leading causes of death in developed countries. Angiex Cancer Therapy examines whether microgravity-cultured endothelial cells represent a valid in vitro model to test effects of vascular-targeted agents on normal blood vessels.

Results may create a model system for designing safer drugs, targeting the vasculature of cancer tumors and helping pharmaceutical companies design safer vascular-targeted drugs.

Chemical Gardens are structures that grow during the interaction of metal salt solutions with silicates, carbonates or other selected anions. Their growth characteristics and attractive final shapes form from a complex interplay between reaction-diffusion processes and self-organization.

On Earth, gravity-induced flow due to buoyancy differences between the reactants complicates our understanding of the physics behind these chemical gardens. Conducting this experiment in a microgravity environment ensures diffusion-controlled growth and allows researchers a better assessment of initiation and evolution of these structures.

These investigations join hundreds of others currently happening aboard the orbiting laboratory.

@yesrazorbladecupcakes: Do you guys ever just goof off?

What did the astronauts on the International Space Station see when they looked upon the Earth from orbit in 2017? See some of the top Earth observations from the year and download these pics, as chosen by our Earth Science and Remote Sensing Unit at the Johnson Space Center in Houston.   Astronauts have used hand-held cameras to photograph the Earth for more than 55 years. Beginning with the Mercury missions in the early 1960s, astronauts have taken more than 1.5 million photographs of the Earth. Today, the International Space Station continues this tradition of Earth observation from human-tended spacecraft. Operational since November 2000, the space station is well suited for documenting Earth features. The orbiting laboratory maintains an altitude of about 250 miles above the Earth, providing an excellent stage for observing most populated areas of the world.

Five Times Astronaut Peggy Whitson Made History

On April 24, 2017, NASA Astronaut Peggy Whitson established the new record for the most time spent in space by an American astronaut. She’s spent more than 76 weeks of her life floating in microgravity!  It’s not the first time in her career at NASA that Whitson has established new milestones: here are just a few.

First NASA Science Officer

Peggy Whitson was the named the first NASA Science Officer aboard the space station in 2002. The position was created to work with the United States research community to understand and meet the requirements and objectives of each space station experiment.

First Female to Command the Space Station… Twice

Whitson became the first female to command the space station during Expedition 16 in 2008. Then Whitson became the first female to command the station twice during her current mission on April 9, 2017.

First Female Chief of the Astronaut Office

In 2009, Whitson became the first female and first non-pilot to achieve the most senior position for active astronauts, Chief of the Astronaut Office.

Most Spacewalks for a Female

On March 30, 2017, Peggy Whitson broke the record for most spacewalks and most time spent spacewalking for female astronauts. Suni Williams had previously held the record at 7 spacewalks.

Most Time In Space By A NASA Astronaut

At 1:27 a.m. ET on April 24, Peggy Whitson set the new record for cumulative time spent in space by an American astronaut. Jeff Williams previously set the record in 2016.

"A classic that I never get tired of: the orange solar panel in front of the blue–white background and the curvature of Earth" wrote astronaut Thomas Pesquet (@thom_astro) of the European Space Agency from aboard the International Space Station. 

The space station serves as the world's leading laboratory for conducting cutting-edge microgravity research, and is the primary platform for technology development and testing in space to enable human and robotic exploration of destinations beyond low-Earth orbit, including Mars.

Aboard the International Space Station, astronaut Thomas Pesquet of the European Space Agency snapped this photo and wrote, 'The view at night recently has been simply magnificent: few clouds, intense #aurora. I can't look away from the windows.' 

The dancing lights of the aurora provide stunning views, but also capture the imagination of scientists who study incoming energy and particles from the sun. Aurora are one effect of such energetic particles, which can speed out from the sun both in a steady stream called the solar wind and due to giant eruptions known as coronal mass ejections or CMEs.
