The NASA Village

It's a long ways down. This is a view from the vantage point of astronaut Shane Kimbrough during his spacewalk last Friday outside the International Space Station. Shane posted this photo and wrote, " View of our spectacular planet (and my boots) during the #spacewalk yesterday with @Thom_astro." During the spacewalk with Kimbrough and Thomas Pesquet of ESA, which lasted just over six-and-a-half hours, the two astronauts successfully disconnected cables and electrical connections to prepare for its robotic move Sunday, March 26.

Two astronauts will venture outside the space station again this Thursday, March 30 for the second of three spacewalks. Kimbrough and Flight Engineer Peggy Whitson will begin spacewalk preparation live on NASA Television starting at 6:30 a.m. EST, with activities beginning around 8 a.m. Watch live online here.

Who is the First Woman? Meet our new graphic novel hero!

Artemis is the first step in the next era of human exploration. This time when we go to the Moon, we're staying, to study and learn more than ever before. We’ll test new technologies and prepare for our next giant leap – sending astronauts to Mars.

Artemis missions will achieve many historic feats, like landing the first woman and first person of color on the Moon.

With today’s release of our graphic novel First Woman: NASA’s Promise for Humanity you don’t have to wait to join us on an inspiring adventure in space.

Meet Commander Callie Rodriguez, the first woman to explore the Moon – at least in the comic book universe.

In Issue No. 1: Dream to Reality, Callie, her robot sidekick RT, and a team of other astronauts are living and working on the Moon in the not-too-distant future. Like any good, inquisitive robot, RT asks Callie how he came to be – not just on the Moon after a harrowing experience stowed in the Orion capsule – but about their origin story, if you will.

From her childhood aspirations of space travel to being selected as an astronaut candidate, Callie takes us on her trailblazing journey to the Moon.

As they venture out to check on a problem at a lunar crater, Callie shares with RT and the crew that she was captivated by space as a kid, and how time in her father’s autobody shop piqued her interest in building things and going places.

Callie learned at a young age that knowledge is gained through both success and failure in the classroom and on the field.

Through disappointment, setbacks, and personal tragedy, Callie pursues her passions and eventually achieves her lifelong dream of becoming an astronaut – a road inspired by the real lives of many NASA astronauts living and working in space today.

So what's up with that lunar crater?

Did Callie pass her math class?

And where did RT come from?

Be a part of the adventure: read (or listen to) the full First Woman story and immerse yourself in a digital experience through our first-ever extended reality-enabled graphic novel.

5 Out-of-This World Technologies Developed for Our Webb Space Telescope

Our James Webb Space Telescope is the most ambitious and complex space science observatory ever built. It will study every phase in the history of our universe, ranging from the first luminous glows after the Big Bang, to the formation of solar systems capable of supporting life on planets like Earth, to the evolution of our own Solar System.

In order to carry out such a daring mission, many innovative and powerful new technologies were developed specifically to enable Webb to achieve its primary mission.  

Here are 5 technologies that were developed to help Webb push the boundaries of space exploration and discovery:

1. Microshutters

Microshutters are basically tiny windows with shutters that each measure 100 by 200 microns, or about the size of a bundle of only a few human hairs. 

The microshutter device will record the spectra of light from distant objects (spectroscopy is simply the science of measuring the intensity of light at different wavelengths. The graphical representations of these measurements are called spectra.)

Other spectroscopic instruments have flown in space before but none have had the capability to enable high-resolution observation of up to 100 objects simultaneously, which means much more scientific investigating can get done in less time. 

Read more about how the microshutters work HERE.

2. The Backplane

Webb's backplane is the large structure that holds and supports the big hexagonal mirrors of the telescope, you can think of it as the telescope’s “spine”. The backplane has an important job as it must carry not only the 6.5 m (over 21 foot) diameter primary mirror plus other telescope optics, but also the entire module of scientific instruments. It also needs to be essentially motionless while the mirrors move to see far into deep space. All told, the backplane carries more than 2400kg (2.5 tons) of hardware.

This structure is also designed to provide unprecedented thermal stability performance at temperatures colder than -400°F (-240°C). At these temperatures, the backplane was engineered to be steady down to 32 nanometers, which is 1/10,000 the diameter of a human hair!

Read more about the backplane HERE.

3. The Mirrors

One of the Webb Space Telescope's science goals is to look back through time to when galaxies were first forming. Webb will do this by observing galaxies that are very distant, at over 13 billion light years away from us. To see such far-off and faint objects, Webb needs a large mirror. 

Webb's scientists and engineers determined that a primary mirror 6.5 meters across is what was needed to measure the light from these distant galaxies. Building a mirror this large is challenging, even for use on the ground. Plus, a mirror this large has never been launched into space before! 

If the Hubble Space Telescope's 2.4-meter mirror were scaled to be large enough for Webb, it would be too heavy to launch into orbit. The Webb team had to find new ways to build the mirror so that it would be light enough - only 1/10 of the mass of Hubble's mirror per unit area - yet very strong. 

Read more about how we designed and created Webb’s unique mirrors HERE.

4. Wavefront Sensing and Control

Wavefront sensing and control is a technical term used to describe the subsystem that was required to sense and correct any errors in the telescope’s optics. This is especially necessary because all 18 segments have to work together as a single giant mirror.

The work performed on the telescope optics resulted in a NASA tech spinoff for diagnosing eye conditions and accurate mapping of the eye.  This spinoff supports research in cataracts, keratoconus (an eye condition that causes reduced vision), and eye movement – and improvements in the LASIK procedure.

Read more about the tech spinoff HERE. 

5. Sunshield and Sunshield Coating

Webb’s primary science comes from infrared light, which is essentially heat energy. To detect the extremely faint heat signals of astronomical objects that are incredibly far away, the telescope itself has to be very cold and stable. This means we not only have to protect Webb from external sources of light and heat (like the Sun and the Earth), but we also have to make all the telescope elements very cold so they don't emit their own heat energy that could swamp the sensitive instruments. The temperature also must be kept constant so that materials aren't shrinking and expanding, which would throw off the precise alignment of the optics.

Each of the five layers of the sunshield is incredibly thin. Despite the thin layers, they will keep the cold side of the telescope at around -400°F (-240°C), while the Sun-facing side will be 185°F (85°C). This means you could actually freeze nitrogen on the cold side (not just liquify it), and almost boil water on the hot side. The sunshield gives the telescope the equivalent protection of a sunscreen with SPF 1 million!

The Sun is not silent. The low, pulsing hum of our star's heartbeat allows scientists to peer inside, revealing huge rivers of solar material flowing around before their eyes — er, ears.

Data from ESA (European Space Agency) and NASA’s Solar and Heliospheric Observatory (SOHO), sonified by the Stanford Experimental Physics Lab, captures the Sun’s natural vibrations and reveals what can’t be seen with the naked eye.

In this audiogram, our heliophysicist Alex Young explains how this simple sound connects us with the Sun and all the other stars in the universe.

Apollo 12: The Next Step after the Giant Leap

Launched less than four months after Apollo 11 put the first astronauts on the Moon, Apollo 12 was more than a simple encore. After being struck by lightning on launch -- to no lasting damage, fortunately -- Apollo 12 headed for a rendezvous with a spacecraft that was already on the Moon. The mission would expand the techniques used to explore the Moon and show the coordination between robotic and human exploration, both of which continue today as we get return to return astronauts to the Moon by 2024. 

Launch Day

Apollo 12 lifted off at 11:22 a.m. EST, Nov. 14, 1969, from our Kennedy Space Center. Aboard the Apollo 12 spacecraft were astronauts Charles Conrad Jr., commander; Richard F. Gordon Jr., command module pilot; and Alan L. Bean, lunar module pilot.

Barely 40 seconds after liftoff, lightning struck the spacecraft. Conrad alerted Houston that the crew had lost telemetry and other data from the mission computers. As the Saturn V engines continued to push the capsule to orbit, ground controllers worked out a solution, restarting some electrical systems, and Apollo 12 headed toward the Moon.

Cameras at the Kennedy Space Center captured this image of the same lightning bolt that struck Apollo 12 striking the mobile platform used for the launch.

On the Moon

Apollo 12 landed on the Moon on Nov. 19, and on the second moonwalk Conrad and Bean walked approximately 200 yards to the Surveyor 3 spacecraft. One of seven Surveyor spacecraft sent to land on the Moon and to gather data on the best way to land humans there, Surveyor 3 had been on the Moon for more than two years, exposed to cosmic radiation and the vacuum of space. Scientists on the ground wanted to recover parts of the spacecraft to see what effects the environment had had on it.

Apollo 12 commander Pete Conrad examines the Surveyor 3 spacecraft before removing its camera and other pieces for return to Earth. In the background is the lunar module that landed Conrad and lunar module pilot Alan Bean on the Moon.

Splashdown

Apollo 12 splashed down on Nov. 24. When Artemis returns astronauts to the Moon in 2024, it will be building on Apollo 12 as much as any of the other missions. Just as Apollo 12 had to maneuver off the standard “free return” trajectory to reach its landing site near Surveyor, Artemis missions will take advantage of the Gateway to visit a variety of lunar locations. The complementary work of Surveyor and Apollo -- a robotic mission preparing the way for a crewed mission; that crewed mission going back to the robotic mission to learn more from it -- prefigures how Artemis will take advantage of commercial lunar landers and other programs to make lunar exploration sustainable over the long term.

Solar System: 5 Things To Know This Week

We live during one of the great eras of exploration. At this very moment, there are dozens of spacecraft surveying the solar system, from Mars, to Saturn, to Pluto and beyond. What’s more, you can ride along with these expeditions — all you need is an internet connection to see the latest discoveries from deep space. Here are a few essential resources for the armchair astronaut:

1. It’s Like Facebook, but for Planets

Or is it more of a Hitchhiker’s Guide to the Solar System? Whatever you want to call it, our Planets page offers quick rundowns, as well as in-depth guides, for all the major bodies in the solar system. Explore from the sun all they way out to the Oort Cloud.

2. Robots to the Rescue

Saturn looks spectacular through a telescope, but there’s only so much you can learn about it from the ground. Going there in person is tough, too. While we are now preparing to send astronauts beyond Earth orbit, a human mission to Saturn won’t be possible in the near future. That’s where the space robots come in. For example, the Cassini spacecraft studies Saturn and its moons up close, sometimes even doing things like flying right through the geyser plumes of the ice moon Enceladus. See all the solar system missions, past and present, where they went and what they’ve seen HERE.

3. Keep Your Eyes on This One

If you still haven’t tried Eyes on the Solar System, you’re missing out. This online simulation lets you tour the planets and track the past, current and future positions of spacecraft — right in your web browser, all in 3D. Eyes on the Solar System uses real NASA data to help you take a virtual flight across both space and time.

4. Images in the Raw

You don’t have to wait for a news release to see pictures from planetary missions. Some missions allow you to see raw, unprocessed images sent straight from the spacecraft. What these images lack in explanatory captions they make up for in freshness — sometimes you can see pictures from Mars or Saturn that are mere hours old. There’s something exhilarating about being among the first human beings ever to see an alien landscape. Peruse our new raw image pages HERE.

5. Bring It On Home

After you’ve toured the far reaches of the solar system, you can always come home again. When you have spent time studying the harsh conditions of our neighboring planets, the charms of a unique paradise come into sharp focus, the place we call Earth. Watch a real-time video feed from Earth orbit HERE. You can also see a daily global view of our planet from a million miles away HERE. Download THIS Earth Now mobile app to hold the planet in your hands.

Are You Ready to #BeTheSpark?

Students - want to modify a NASA Spinoff technology and solve a real word problem?

Our Optimus Prime Spinoff Promotion and Research Challenge, known as OPSPARC for short, is a student challenge that guides teams through various NASA Spinoff technologies that are in their everyday world. The teams use their imagination, creativity, and engineering skills to develop their own ideas for NASA spinoff technology.

Spinoffs are technologies originally created for space and modified into everyday products used here on Earth.

Perhaps the most widely recognized NASA spinoff, memory foam was invented by NASA-funded researchers looking for ways to keep test pilots cushioned during flights. Today, memory foam makes for more comfortable beds, couches and chairs, not to mention better shoes, movie theater seats and even football helmets.

There are more than two-thousand NASA Spinoffs They include memory foam, invisible braces, firefighting equipment, programmable pace makers, artificial limbs, scratch-resistant lenses, aircraft anti-icing systems, endangered species tracking software, cochlear implants, satellite television, long-distance telecommunications, and many, many more.

The deadline has been extended to February 26th for our Mission 3 student challenge. Sign up NOW here: https://opsparc.gsfc.nasa.gov/

Fans of the Hasbro TRANSFORMERS brand will pick up on the play on words between the challenge name, OPSPARC, and the "AllSpark" from the TRANSFORMERS universe. The AllSpark is what gave the TRANSFORMERS robots life and knowledge, which they use to help mankind — just like NASA spinoffs. Students from around the globe will have the opportunity to Be The Spark!
