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.
Satellites are crucial to everyday life and cost hundreds of millions of dollars to manufacture and launch. Currently, they are simply decommissioned when they run out of fuel. There is a better way, and it centers on satellite servicing, which can make spaceflight more sustainable, affordable, and resilient. Our satellite servicing technologies will open up a new world where fleet managers can call on robotic mechanics to diagnose, maintain and extend the lifespan of their assets.
Our new and unique robot is designed to test robotic satellite servicing capabilities. Standing 10 feet tall and 16 feet wide, the six-legged “hexapod” robot helps engineers perfect technologies before they’re put to use in space.
Here are SIX interesting facts about the hexapod:
This essentially means the robot can move in six directions—three translational directions (forward and backward, up and down and left and right), and three rotational directions (roll, pitch and yaw). Because of its wide range of movement, the hexapod mimics the way a satellite moves in zero gravity.
Like most space simulators, the hexapod typically moves slowly at about one inch per second. During tests, it remains positioned about nine feet off the floor to line up with and interact with a robotic servicing arm mounted to an arch nearby. However, the robot can move at speeds up to eight inches per second and extend/reach nearly 13 feet high!
The hexapod is crucial to testing for our Restore-L project, which will prove a combination of technologies needed to robotically refuel a satellite not originally designed to be refueled in space.
Perhaps the most difficult part of refueling a satellite in space is the autonomous rendezvous and grapple stage. A satellite in need of fuel might be moving 16,500 miles per hour in the darkness of space. A servicer satellite will need to match its speed and approach the client satellite, then grab it. This nail-biting stage needs to be done autonomously by the spacecraft’s systems (no humans controlling operations from the ground).
The hexapod helps us practice this never-before-attempted feat in space-like conditions. Eventually a suite of satellite servicing capabilities could be incorporated in other missions.
Because of the hexapod’s unparalleled* ability to handle a high load capacity and range of movement, while maintaining a high degree of precision and repeatability, a similar kind of robot is used for flight and roller coaster simulators.
*Pun intended: the hexapod is what is referred to as a parallel motion robot
The hexapod was designed and built by a small, New Hampshire-based company called Mikrolar. Mikrolar designs and produces custom robots that offer a wide range of motion and high degree of precision, for a wide variety of applications.
The hexapod conducts crucial tests at our Goddard Space Flight Center’s Robotic Operations Center (ROC). The ROC is a 5,000-square-foot facility with 50 feet high ceilings. It acts as an incubator for satellite servicing technologies. Within its black curtain-lined walls, space systems, components and tasks are put to the test in simulated environments, refined and finally declared ready for action in orbit.
The hexapod is not alone in the ROC. Five other robots test satellite servicing capabilities. Engineers use these robots to practice robotic repairs on satellites rendezvousing with objects in space.

The holiday season is here! You might think that your celebrations are WAY different than what is done on the International Space Station, but you might be surprised…Here are a few ways your holidays might be similar to the crew on the space station:
1. You’re Instagramming All Your Decorations
Yep! Just like on Earth, the space station crew has the capability to use social media while on orbit. If you don’t follow them, you should check it out and get an out of this world perspective of what life is like on the International Space Station. (Expedition 34 crew members assemble in the Unity node of the space station for a brief celebration of the Christmas holiday on Dec. 24, 2012.)
2. You Have to Make Sure to Call Your Relatives
You don’t want to forget to wish Aunt Sue “Happy Holidays”, she might not send you a gift next year! The crew on the space station have the ability to talk to their loved ones every day. (Cosmonaut Mikhail Tyurin, and astronauts Michael E. Lopez-Alegria and Sunita L. Williams conduct a teleconference on Dec. 25, 2006.)
3. The Family Photos Never Seem to End
The crew on the station might not be related by blood, or even country of birth, but they share living space, meals and time together just like a family on Earth. And when it comes to the holidays, you bet they’ll be snapping pictures to capture the moments. (The six Expedition 30 crew members assemble in the U.S. Lab aboard the space station for a brief celebration of the Christmas holiday on Dec. 25, 2011.)
4. Meal Prep is a Task Shared by All
When you’re making food for multiple people, everyone needs to pitch in and help…the crew on the space station included! (Astronauts Michael Fincke, Sandra Magnus and cosmonaut Yury Lonchakov, pose for a photo as they prepare to share a Christmas meal on the space station on Dec. 25, 2008.)
5. Eating Cookies is a Must
What would the holidays be like without eating cookies? They even have the chance to eat them in space…pretty cool! (Astronauts Michael Fincke and Sandra Magnus hold Christmas cookies while posing for a photo near the galley on the space station on Dec. 25, 2008.)

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.

Wow, time has gone by extremely fast. The mid-deployment phase will be short-lived for me this time, as the new crew (Drew Feustel, Ricky Arnold, and Oleg Artemyev) will arrive on March 23rd, and then we have at least one spacewalk on the 29th, followed by a planned SpaceX Dragon cargo craft arrival on the 4th of April. It’s a little strange being up here with only two other crewmates. We are still very busy, but the overall work effort is half of what it was just a week ago. My crewmate, Nemo (Norishige Kanai), and I are trying to use the time to prepare for the upcoming very busy schedule, and we have been having some great success getting a ton of details taken care of.
Yesterday I had a funny event, though. I was controlling a robot named “Justin” who was located in Munich. The research and demonstration events were so interesting and fun that I offered them my lunch hour to do an additional protocol and have a longer debrief session. The ground team responded happily and accepted the offer – any extra time with crew onboard the International Space Station (ISS) is valuable to our programs. Halfway through the event, the team needed a few minutes to shut down and restart the robot, and I surmised that since I was skipping my break, this would be a good time to use the toilet. And I did, use the toilet. And literally 3 minutes later I returned, waited another 2 minutes for the robot systems to connect, and we began another great session controlling Justin from ISS with no loss to science.
Later that same day, I was approached by the ground team in Houston (not the test team I was working with in Munich) and queried if something was wrong, and why did I have to take a toilet break while we were executing valuable science? They were concerned that I might have a medical issue, as taking a break in the middle of some very valuable science is not normal for us to do while on ISS. It’s nice to know that we have literally hundreds of highly-trained professionals looking out for us.

Is it safe to look at the eclipse if it isn't fully covered by the sun? Say 75%
Not without proper eye wear. There will still be too much light that could burn your eyes. But you can have a ton of fun viewing the Sun using a https://eclipse.aas.org/eye-safety/projection. In fact, there is a sunspot that is now on the Sun that you should be able to see using this indirect method!
On November 14, NASA is set to launch the uncrewed Artemis I flight test to the Moon and back. Artemis I is the first integrated flight test of the Space Launch System (SLS) rocket, the Orion spacecraft, and Exploration Ground Systems at NASA’s Kennedy Space Center in Florida. These are the same systems that will bring future Artemis astronauts to the Moon.
Standing 322 feet (98 meters) tall, the SLS rocket comprises of a core stage, an upper stage, two solid boosters, and four RS-25 engines. The SLS rocket is the most powerful rocket in the world, able to carry 59,500 pounds (27 metric tons) of payloads to deep space — more than any other vehicle. With its unprecedented power, SLS is the only rocket that can send the Orion spacecraft, astronauts, and cargo directly to the Moon on a single mission.
Before launch, Artemis I has some big help: the Vehicle Assembly Building (VAB) at KSC is the largest single-story building in the world. The VAB was constructed for the assembly of the Apollo/Saturn V Moon rocket, and this is where the SLS rocket is assembled, maintained, and integrated with the Orion spacecraft.
The mobile launcher is used to assemble, process, and launch the SLS rocket and Orion spacecraft. The massive structure consists of a two-story base and a tower equipped with a number of connection lines to provide the rocket and spacecraft with power, communications, coolant, and fuel prior to launch.
Capable of carrying 18 million pounds (8.2 million kg) and the size of a baseball infield, crawler-transporter 2 will transport SLS and Orion the 4.2 miles (6.8 km) to Launch Pad 39B. This historic launch pad was where the Apollo 10 mission lifted off from on May 18, 1969, to rehearse the first Moon landing.
During the launch, SLS will generate around 8.8 million pounds (~4.0 million kg) of thrust, propelling the Orion spacecraft into Earth’s orbit. Then, Orion will perform a Trans Lunar Injection to begin the path to the Moon. The spacecraft will orbit the Moon, traveling 40,000 miles beyond the far side of the Moon — farther than any human-rated spacecraft has ever flown.
The Orion spacecraft is designed to carry astronauts on deep space missions farther than ever before. Orion contains the habitable volume of about two minivans, enough living space for four people for up to 21 days. Future astronauts will be able to prepare food, exercise, and yes, have a bathroom. Orion also has a launch abort system to keep astronauts safe if an emergency happens during launch, and a European-built service module that fuels and propels the spacecraft.
While the Artemis I flight test is uncrewed, the Orion spacecraft will not be empty: there will be three manikins aboard the vehicle. Commander Moonikin Campos will be sitting in the commander’s seat, collecting data on the vibrations and accelerations future astronauts will experience on the journey to the Moon. He is joined with two phantom torsos, Helga and Zohar, in a partnership with the German Aerospace Center and Israeli Space Agency to test a radiation protection vest.
A host of shoebox-sized satellites called CubeSats help enable science and technology experiments that could enhance our understanding of deep space travel and the Moon while providing critical information for future Artemis missions.
At the end of the four-week mission, the Orion spacecraft will return to Earth. Orion will travel at 25,000 mph (40,000 km per hour) before slowing down to 300 mph (480 km per hour) once it enters the Earth’s atmosphere. After the parachutes deploy, the spacecraft will glide in at approximately 20 mph (32 km per hour) before splashdown about 60 miles (100 km) off the coast of California. NASA’s recovery team and the U.S. Navy will retrieve the Orion spacecraft from the Pacific Ocean.
With the ultimate goal of establishing a long-term presence on the Moon, Artemis I is a critical step as NASA prepares to send humans to Mars and beyond.

On Saturday, October 20, NASA will host the ninth annual International Observe the Moon Night. One day each year, everyone on Earth is invited to observe and learn about the Moon together, and to celebrate the cultural and personal connections we all have with our nearest celestial neighbor.
There are a number of ways to celebrate. You can attend an event, host your own, or just look up! Here are 10 of our favorite ways to observe the Moon:
Image credit: NASA’s Scientific Visualization Studio/Ernie Wright
The simplest way to observe the Moon is simply to look up. The Moon is the brightest object in our night sky, the second brightest in our daytime sky and can be seen from all around the world — from the remote and dark Atacama Desert in Chile to the brightly lit streets of Tokyo. On October 20, the near side of the Moon, or the side facing Earth, will be about 80 percent illuminated, rising in the early evening.
See the Moon phase on October 20 or any other day of the year!

Have you heard the news? Astronaut applications are opening soon (March 2), and there’s never been a better time to apply then now. Here are a few signs that might mean you’re ready to take to the stars:
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.
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.
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.
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 monitoring veggie growth 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.
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!
Space is a place where people from all around the world come together to push the boundaries of human exploration. Whether you’re living on the space station with an international crew, or embarking on Artemis missions to the Moon – you’re sure to make new friendships wherever you go.
Meal time is family time aboard the space station, and what better way to bond than pizza night! Getting to know your crew mates AND channelling your inner chef is always a win win.
The International Space Station orbits Earth 16 times a day, so get ready to rack up those frequent flyer miles! A favorite past time of many astronauts is Earth watching from the station’s cupola observatory. Get lost in the Pacific Ocean’s blue hue, gaze at the Himalayas or photograph your favorite cities all from a bird’s eye view. Get assigned to an Artemis Moon mission? Even better! Have fun expanding your travels to the solar system.
Perk about the job? Your childhood dreams to fly finally come true. Whether you’re floating around the International Space Station or getting adjusted to our new spaceship, Gateway, your inner superhero will be beaming.
Astronauts don’t just push the boundaries of human exploration, they also help pave the way for scientific breakthroughs back at home. Thanks to the microgravity environment of space, discoveries not possible on Earth are able to be unlocked. Investigations into Parkinson’s Disease, cancer and more have been conducted on the orbital lab.
Interested in applying to become an astronaut? You’re in luck, applications are open from March 2- 31! Learn about some common myths about becoming an astronaut HERE.

As our Cassini spacecraft enters its final 20 months before its plunge into Saturn, the mission’s science team has selected their top 10 images from 2015 (above), a year of historic discoveries, as well as the top science results (below). Take a look:
1. First Deep Seafloor Hydrothermal Vents Found Beyond Earth
Cassini found the first evidence of active hot-water chemistry beyond planet Earth. An extensive, four-year analysis of data from the spacecraft, computer simulations and laboratory experiments led researchers to the conclusion the tiny silica (SiCO2) grains most likely form when hot water containing dissolved minerals from the moon’s rocky interior travels upward, coming into contact with cooler water.
2. Global Ocean Beneath Enceladus’ Surface
A global ocean lies beneath the icy crust of Saturn’s geologically active moon Enceladus. Scientists analyzed more than seven years’ worth of images of Enceladus taken by the spacecraft, which has been orbiting Saturn since mid-2004. As a result, they found Enceladus has a tiny, but measurable wobble as it orbits Saturn. This proves that there must be a global layer of liquid separating the surface from the core.
3. Titan Observed Outside of Saturnian Magnetosphere
During Cassini’s flyby of Titan, the giant moon happened to be on the sunward side of Saturn when a powerful outburst of solar activity reached the planet. The strong surge in the solar wind so compressed the sun-facing side of Saturn’s magnetosphere that the bubble’s outer edge was pushed inside the orbit of Titan. This left the moon exposed to, and unprotected from, the raging stream of energetic solar particles. The region of space dominated by Saturn’s magnetic field is called the magnetosphere.
4. Density of a Ring Particles May Indicate Recent Origins
Saturn’s A ring was found to be warmer than expected at the planet’s equinox, and also had an unusually large thermal asymmetry about the equinox. This could be due to the A ring being mostly composed of denser particles made primarily of solid ice, with a thin top layer of fluffy regolith.
5. Titan Southern Polar Ice Cloud
Scientists have detected a monstrous new cloud of frozen compounds in Titan’s low- to mid-stratosphere – a stable atmospheric region above the troposphere, or active weather layer.
6. Curtain Vents on Enceladus?
New research using data from Cassini suggests most of the eruptions from Saturn’s moon Enceladus might actually be diffuse curtains rather than discrete jets. Many features that appear to be individuals jets of material erupting along the length of prominent “tiger stripe” fractures in the moon’s south polar region might be phantoms created by an optical illusion, according to the new study.
7. Discovery of Tethys Red Arcs
Like graffiti sprayed by an unknown artist, unexplained arc-shaped, reddish streaks are visible on the surface of Saturn’s icy moon Tethys. The origin of the features and their reddish color is a mystery to scientists.
8. Saturn’s 30-year Giant Storms Powered by Water Convection
Changes in temperature and the composition of the hydrogen-laden air within the remnants of a giant storm system on Saturn reveal that air was lofted more than 120 miles in altitude from the deeper water condensation levels.
9. Seasonal Change Seen at Saturn’s Poles
Saturn’s polar regions have displayed extreme seasonal changes during Cassini’s decade-long watch, providing the most comprehensive view ever obtained of seasonal change on a giant planet.
10. Huygens Probe Imaging Mosaic of Titan’s Surface and Descent Movie
Ten years ago, an explorer from Earth, the Huygens probe, was released from the Cassini spacecraft and parachuted into the haze of an alien moon toward an uncertain fate. After a gentle descent lasting more than two hours, it landed with a thud on a frigid floodplain on Titan, surrounded by icy cobblestones.

By now everyone knows that we are to thank for the memory foam in your mattress and the camera in your cell phone. (Right? Right.)
But our technology is often also involved behind the scenes—in ways that make the products we use daily safer and stronger, and in some cases, that can even save lives.
Here are some examples from this year’s edition of Spinoff, our yearly roundup of “space in your life”:
What happens to your car bumper in an accident? When does it crumple and when does it crack? And are all bumpers coming off the assembly line created equal?
These types of questions are incredibly important when designing a safe car, and one technology that helps almost every U.S. automobile manufacturer find answers is something we helped develop when we had similar questions about the Space Shuttle.
Before flying again after the Columbia disaster in 2003, we had to be sure we understood what went wrong and how to prevent it from ever happening again. We worked with Trilion, Inc. to develop a system using high-speed cameras and software to analyze every impact—from the one that actually happened on the Shuttle to any others we could imagine—and design fixes.
We’re pretty good at finding things you can’t see with the naked eye—from distant exoplanets to water on Mars.
But there are also plenty of uses for that know-how on Earth.
One example that has already saved lives: locating heartbeats under debris.
Engineers at our Jet Propulsion Laboratory adapted technology first devised to look for gravity fluctuations to create FINDER, which stands for Finding Individuals for Disaster and Emergency Response and can detect survivors through dense rubble.
We have licensed the technology to two companies, including R4, and it has already been used in natural disaster responses, including after earthquakes in Nepal, Mexico City, Ecuador, and after Hurricane Maria in Puerto Rico.
As we have seen this year with devastating wildfires in California, forest fires can spread incredibly quickly.
Knowing when to order an evacuation, where to send firefighters, and how to make every other decision—all amid a raging inferno—depends on having the most up-to-date information as quickly as possible.
Using our expertise in remote sensing and communicating from space, we helped the U.S. Forest Service make its process faster and more reliable, so the data from airborne sensors gets to decision makers on the front line and at the command center in the blink of an eye.
When paramedics come racing into a home, the last thing anybody is worrying about is where the ambulance was earlier that morning. A device we helped create ensures you won’t have to.
AMBUstat creates a fog that sterilizes every surface in an ambulance in minutes, so any bacteria, viruses or other contaminants won’t linger on to infect the next patient.
This technology works its magic through the power of atomic oxygen—the unpaired oxygen atoms that are common in the upper reaches of Earth’s atmosphere. We’ve had to learn about these atoms to devise ways to ensure they won’t destroy our spacecraft or harm astronauts, but here, we were able to use that knowledge to direct that destructive power at germs.
Did you know the air we breathe inside buildings is often up to 10 times more polluted than the air outdoors?
Put the air under a microscope and it’s not pretty, but a discovery we made in the 1990s can make a big impact.
We were working on a way to clear a harmful chemical that accumulates around plants growing on a spacecraft, and it turned out to also neutralize bacteria, viruses, and mold and eliminate volatile organic compounds.
Now air purifiers using this technology are deployed in hospital operating rooms, restaurant kitchens, and even major baseball stadiums to improve air quality and keep everyone healthier. Oh, and you can buy one for your house, too.
Car companies are moving full-speed ahead to build the driverless cars of the not-so-distant future. Software first created to help self-learning robots navigate on Mars may help keep passengers and pedestrians safer once those cars hit the road. The software creates an artificially intelligent “brain” for a car (or drone, for that matter) that can automatically identify and differentiate between cars, trucks, pedestrians, cyclists, and more, helping ensure the car doesn’t endanger any of them.
So, now that you know a few of the spinoff technologies that we helped develop, you can look for them throughout your day. Visit our page to learn about more spinoff technologies: https://spinoff.nasa.gov Make sure to follow us on Tumblr for your regular dose of space: http://nasa.tumblr.com.
In July 2015, we saw Pluto up close for the first time and—after three years of intense study—the surprises keep coming. “It’s clear,” says Jeffery Moore, New Horizons’ geology team lead, “Pluto is one of the most amazing and complex objects in our solar system.”
These are combined observations of Pluto over the course of several decades. The first frame is a digital zoom-in on Pluto as it appeared upon its discovery by Clyde Tombaugh in 1930. More frames show of Pluto as seen by the Hubble Space Telescope. The final sequence zooms in to a close-up frame of Pluto taken by our New Horizons spacecraft on July 14, 2015.
Pluto’s surface sports a remarkable range of subtle colors are enhanced in this view to a rainbow of pale blues, yellows, oranges, and deep reds. Many landforms have their own distinct colors, telling a complex geological and climatological story that scientists have only just begun to decode. The image resolves details and colors on scales as small as 0.8 miles (1.3 kilometers). Zoom in on the full resolution image on a larger screen to fully appreciate the complexity of Pluto’s surface features.
July 14, 2015: New Horizons team members Cristina Dalle Ore, Alissa Earle and Rick Binzel react to seeing the spacecraft's last and sharpest image of Pluto before closest approach.
Just 15 minutes after its closest approach to Pluto, the New Horizons spacecraft captured this near-sunset view of the rugged, icy mountains and flat ice plains extending to Pluto's horizon. The backlighting highlights more than a dozen layers of haze in Pluto's tenuous atmosphere. The image was taken from a distance of 11,000 miles (18,000 kilometers) to Pluto; the scene is 780 miles (1,250 kilometers) wide.
Found near the mountains that encircle Pluto’s Sputnik Planitia plain, newly discovered ridges appear to have formed out of particles of methane ice as small as grains of sand, arranged into dunes by wind from the nearby mountains.
The vast nitrogen ice plains of Pluto’s Sputnik Planitia – the western half of Pluto’s “heart”—continue to give up secrets. Scientists processed images of Sputnik Planitia to bring out intricate, never-before-seen patterns in the surface textures of these glacial plains.
High resolution images of Pluto’s largest moon, Charon, show a surprisingly complex and violent history. Scientists expected Charon to be a monotonous, crater-battered world; instead, they found a landscape covered with mountains, canyons, landslides, surface-color variations and more.
One of two potential cryovolcanoes spotted on the surface of Pluto by the New Horizons spacecraft. This feature, known as Wright Mons, was informally named by the New Horizons team in honor of the Wright brothers. At about 90 miles (150 kilometers) across and 2.5 miles (4 kilometers) high, this feature is enormous. If it is in fact an ice volcano, as suspected, it would be the largest such feature discovered in the outer solar system.
Pluto's receding crescent as seen by New Horizons at a distance of 120,000 miles (200,000 kilometers). Scientists believe the spectacular blue haze is a photochemical smog resulting from the action of sunlight on methane and other molecules in Pluto's atmosphere. These hydrocarbons accumulate into small haze particles, which scatter blue sunlight—the same process that can make haze appear bluish on Earth.
On Jan. 1, 2019, New Horizons will fly past a small Kuiper Belt Object named MU69 (nicknamed Ultima Thule)—a billion miles (1.5 billion kilometers) beyond Pluto and more than four billion miles (6.5 billion kilometers) from Earth. It will be the most distant encounter of an object in history—so far—and the second time New Horizons has revealed never-before-seen landscapes.
