What You Should Know About Scott Kelly’s #YearInSpace

A Spacecraft's Second Life: Our K2 mission

A critical failure that ended one mission has borne an unexpected and an exciting new science opportunity. The Kepler spacecraft, known for finding thousands of planets orbiting other stars, has a new job as the K2 mission.

Like its predecessor, K2 detects the tiny, telltale dips in the brightness of a star as an object passes or transits it, to possibly reveal the presence of a planet. Searching close neighboring stars for near-Earth-sized planets, K2 is finding planets ripe for follow-up studies on their atmospheres and to see what the planet is made of. A step up from its predecessor, K2 is revealing new info on comets, asteroids, dwarf planets, ice giants and moons. It will also provide new insight into areas as diverse as the birth of new stars, how stars explode into spectacular supernovae, and even the evolution of black holes.

K2 is expanding the planet-hunting legacy and has ushered in entirely new opportunities in astrophysics research, yet this is only the beginning.

Searching Nearby for Signs of Life

Scientists are excited about nearby multi-planet system known as K2-3. This planetary system, discovered by K2, is made of three super-Earth-sized planets orbiting a cool M-star (or red dwarf) 135 light-years away, which is relatively close in astronomical terms. To put that distance into perspective, if the Milky Way galaxy was scaled down to the size of the continental U.S. it would be the equivalent of walking the three-mile long Golden Gate Park in San Francisco, California. At this distance, our other powerful space-investigators – the Hubble Space Telescope and the forthcoming James Webb Space Telescope (JWST) – could study the atmospheres of these worlds in search of chemical fingerprints that could be indicative of life. K2 expects to find a few hundred of these close-by, near-Earth-sized neighbors.

K2 won’t be alone in searching for nearby planets outside our solar system. Revving up for launch around 2017-2018, our Transiting Exoplanet Survey Satellite (TESS) plans to monitor 200,000 close stars for planets, with a focus on finding Earth and Super-Earth-sized planets.

Neptune's Moon Dance

Spying on our neighbors in our own solar system, K2 caught Neptune in a dance with its moons Triton and Nereid. On day 15 (day counter located in the top right-hand corner of the green frame) of the sped-up movie, Neptune appears, followed by its moon Triton, which looks small and faint. Keen-eyed observers can also spot Neptune's tiny moon Nereid at day 24. Neptune is not moving backward but appears to do so because of the changing position of the Kepler spacecraft as it orbits around the sun. A few fast-moving asteroids make cameo appearances in the movie, showing up as streaks across the K2 field of view. The red dots are a few of the stars K2 examines in its search for transiting planets outside of our solar system. An international team of astronomers is using these data to track Neptune’s weather and probe the planet’s internal structure by studying subtle brightness fluctuations that can only be observed with K2.

Dead Star Devours Planet

K2 also caught a white dwarf – the dead core of an exploded star –vaporizing a nearby tiny rocky planet. Slowly the planet will disintegrate, leaving a dusting of metals on the surface of the star. This trail of debris blocks a tiny fraction of starlight from the vantage point of the spacecraft producing an unusual, but vaguely familiar pattern in the data. Recognizing the pattern, scientists further investigated the dwarf’s atmosphere to confirm their find. This discovery has helped validate a long-held theory that white dwarfs are capable of cannibalizing possible remnant planets that have survived within its solar system.

Searching for Far Out Worlds

NASA/JPL-Caltech

In April, spaced-based K2 and ground-based observatories on five continents will participate in a global experiment in exoplanet observation and simultaneously monitor the same region of sky towards the center of our galaxy to search for small planets, such as the size of Earth, orbiting very far from their host star or, in some cases, orbiting no star at all. For this experiment, scientists will use gravitational microlensing – the phenomenon that occurs when the gravity of a foreground object focuses and magnifies the light from a distant background star.

The animation demonstrates the principles of microlensing. The observer on Earth sees the source (distant) star when the lens (closer) star and planet pass through the center of the image. The inset shows what may be seen through a ground-based telescope. The image brightens twice, indicating when the star and planet pass through the observatory's line of sight to the distant star.

One Hot Year after Another

Globally, 2020 was the hottest year on record, effectively tying 2016, the previous record. Overall, Earth’s average temperature has risen more than 2 degrees Fahrenheit since the 1880s.

Temperatures are increasing due to human activities, specifically emissions of greenhouse gases, like carbon dioxide and methane. 

Heat and the energy it carries are what drive our planet: winds, weather, droughts, floods, and more are expressions of heat. The right amount of heat is even one of the things that makes life on Earth possible. But too much heat is changing the way our planet’s systems act.

My World’s on Fire

Higher temperatures drive longer, more intense fire seasons. As rain and snowfall patterns change, some regions are getting drier and more vulnerable to damage, setting the stage for more fires.

2020 saw several record-breaking fires, both in Australia in the beginning of the year, and in the western U.S. through northern summer and fall. Smoke from fires in both regions reached so high into the atmosphere that it formed clouds and continues to travel around the globe today.

In the Siberian Arctic, unusually high temperatures helped drive at least 19 fires in the region. More than half of them were burning peat soil -- decomposed organic materials -- that stores a lot of carbon. Peat fires release vast amounts of carbon into the atmosphere, potentially leading to even more warming.

The Water’s Getting Warm

It wasn’t just fire seasons setting records. 2020 had more named tropical storms in the Atlantic and more storms making landfall in the U.S. than any hurricane season on record.

Hurricanes rely on warm ocean water as fuel, and this year, the Atlantic provided. 30 named storms weren’t the only things that made this year’s hurricane season notable.

Storms like Eta, Delta, and Iota quickly changed from smaller, weaker tropical storms into more destructive hurricanes. This rapid intensification is complicated, but it’s likely that warmer, more humid weather -- a result of climate change -- helps drive it.

The Ice Is Getting Thin

Add enough heat, and even the biggest chunk of ice will melt. That’s true whether we’re talking about the ice cubes in your glass or the vast sheets of ice at our planet’s poles. Right now, the Arctic region is warming about three times faster than the rest of our planet, which has some major effects both locally and globally.

This year, Arctic sea ice hit a near-record low. Sea ice is actually made of frozen ocean water, and it grows and thaws with the seasons, typically reaching an annual minimum extent in September.

Warmer ocean water led to more ice melting this year, and 2020’s annual minimum extent continued a long trend of shrinking Arctic sea ice extent.

A Long Trend

We study Earth and how it’s changing from the ground, the sky, and space. Using data from sensors all around the planet, we calculate the global average temperature, working with our partners at NOAA.

Many other organizations also track global temperature using their own instruments and methods, and they all match remarkably well. The last seven years were the hottest seven years on record. Earth is getting warmer.

We also study the effects of increasing temperatures, like the melting sea ice and longer fire seasons mentioned above. Additionally, we can study the cause of climate change from space, with a bird’s eye view of increasing carbon in the atmosphere.

The planet is changing because of human activities. We’re working together with other agencies to monitor changes and understand what this means for people in the future.

Did you recently hear that NASA changed the zodiac signs? Nope, we definitely didn’t…

Constellations and the Calendar

Did you recently hear that NASA changed the zodiac signs? Nope, we definitely didn’t…

…Here at NASA, we study astronomy, not astrology. We didn’t change any zodiac signs, we just did the math. Here are the details:

First Things First: Astrology is not Astronomy…

Astronomy is the scientific study of everything in outer space. Astronomers and other scientists know that stars many light-years away have no effect on the ordinary activities of humans on Earth.

Astrology, meanwhile, is something else. It’s the belief that the positions of stars and planets can influence human events. It’s not considered a science.

Some curious symbols ring the outside of the Star Finder. These symbols stand for some of the constellations in the zodiac. What is the zodiac and what is special about these constellations?

Imagine a straight line drawn from Earth though the sun and out into space way beyond our solar system where the stars are. Then, picture Earth following its orbit around the sun. This imaginary line would rotate, pointing to different stars throughout one complete trip around the sun – or, one year. All the stars that lie close to the imaginary flat disk swept out by this imaginary line are said to be in the zodiac.

The constellations in the zodiac are simply the constellations that this imaginary straight line points to in its year-long journey.

What are Constellations?

A constellation is group of stars like a dot-to-dot puzzle. If you join the dots—stars, that is—and use lots of imagination, the picture would look like an object, animal, or person. For example, Orion is a group of stars that the Greeks thought looked like a giant hunter with a sword attached to his belt. Other than making a pattern in Earth’s sky, these stars may not be related at all.

Even the closest star is almost unimaginably far away. Because they are so far away, the shapes and positions of the constellations in Earth’s sky change very, very slowly. During one human lifetime, they change hardly at all.

A Long History of Looking to the Stars

The Babylonians lived over 3,000 years ago. They divided the zodiac into 12 equal parts – like cutting a pizza into 12 equal slices. They picked 12 constellations in the zodiac, one for each of the 12 “slices.” So, as Earth orbits the sun, the sun would appear to pass through each of the 12 parts of the zodiac. Since the Babylonians already had a 12-month calendar (based on the phases of the moon), each month got a slice of the zodiac all to itself.

But even according to the Babylonians’ own ancient stories, there were 13 constellations in the zodiac. So they picked one, Ophiuchus, to leave out. Even then, some of the chosen 12 didn’t fit neatly into their assigned slice of the pie and crossed over into the next one.

When the Babylonians first invented the 12 signs of zodiac, a birthday between about July 23 and August 22 meant being born under the constellation Leo. Now, 3,000 years later, the sky has shifted because Earth’s axis (North Pole) doesn’t point in quite the same direction.

The constellations are different sizes and shapes, so the sun spends different lengths of time lined up with each one. The line from Earth through the sun points to Virgo for 45 days, but it points to Scorpius for only 7 days.  To make a tidy match with their 12-month calendar, the Babylonians ignored the fact that the sun actually moves through 13 constellations, not 12. Then they assigned each of those 12 constellations equal amounts of time.

So, we didn’t change any zodiac signs…we just did the math.

Five Ways the International Space Station’s National Lab Enables Commercial Research

A growing number of commercial partners use the International Space Station National Lab. With that growth, we will see more discoveries in fundamental and applied research that could improve life on the ground.

Space Station astronaut Kate Rubins was the first person to sequence DNA in microgravity.

Since 2011, when we engaged the Center for the Advancement of Science in Space (CASIS) to manage the International Space Station (ISS) National Lab, CASIS has partnered with academic researchers, other government organizations, startups and major commercial companies to take advantage of the unique microgravity lab. Today, more than 50 percent of CASIS’ experiments on the station represent commercial research.

Here’s a look at five ways the ISS National Lab is enabling new opportunities for commercial research in space.

1. Supporting Commercial Life Sciences Research

One of the main areas of focus for us in the early origins of the space station program was life sciences, and it is still a major priority today. Studying the effects of microgravity on astronauts provides insight into human physiology, and how it evolves or erodes in space. CASIS took this knowledge and began robust outreach to the pharmaceutical community, which could now take advantage of the microgravity environment on the ISS National Lab to develop and enhance therapies for patients on Earth. Companies such as Merck, Eli Lilly & Company, and Novartis have sent several experiments to the station, including investigations aimed at studying diseases such as osteoporosis, and examining ways to enhance drug tablets for increased potency to help patients on Earth. These companies are trailblazers for many other life science companies that are looking at how the ISS National Lab can advance their research efforts.

2. Enabling Commercial Investigations in Material and Physical Sciences

Over the past few years, CASIS and the ISS National Lab also have seen a major push toward material and physical sciences research by companies interested in enhancing their products for consumers. Examples range from Proctor and Gamble’s investigation aimed at increasing the longevity of daily household products, to Milliken’s flame-retardant textile investigation to improve protective clothing for individuals in harm’s way, and companies looking to enhance materials for household appliances. Additionally, CASIS has been working with a variety of companies to improve remote sensing capabilities in order to better monitor our oceans, predict harmful algal blooms, and ultimately, to better understand our planet from a vantage point roughly 250 miles above Earth.

3. Supporting Startup Companies Interested in Microgravity Research 

CASIS has funded a variety of investigations with small startup companies (in particular through seed funding and grant funding from partnerships and funded solicitations) to leverage the ISS National Lab for both research and test-validation model experiments. CASIS and The Boeing Company recently partnered with MassChallenge, the largest startup accelerator in the world, to fund three startup companies to conduct microgravity research.

4. Enabling Validation of Low-Earth Orbit Business Models 

The ISS National Lab helps validate low-Earth orbit business models. Companies such as NanoRacks, Space Tango, Made In Space, Techshot, and Controlled Dynamics either have been funded by CASIS or have sent instruments to the ISS National Lab that the research community can use, and that open new channels for inquiry. This has allowed the companies that operate these facilities to validate their business models, while also building for the future beyond station.

5. Demonstrating the Commercial Value of Space-based Research

We have been a key partner in working with CASIS to demonstrate to American businesses the value of conducting research in space. Through outreach events such as our Destination Station, where representatives from the International Space Station Program Science Office and CASIS select cities with several major companies and meet with the companies to discuss how they could benefit from space-based research. Over the past few years, this outreach has proven to be a terrific example of building awareness on the benefits of microgravity research.

What is the best about being mission control?

Happy #MoonDay! To celebrate the 49th anniversary of Apollo 11 landing on the Moon, we present you with “Moonlight,” a video by our Goddard science visualizer Ernie Wright set to Debussy’s Clair de Lune. The Apollo missions were a landmark in lunar exploration. The visit and the samples that our Moon walkers collected transformed our understanding of the Moon and the solar system. Now, our Lunar Reconnaissance Orbiter’s high-resolution data gives an incredibly detailed view of our closest neighbor.

This visualization captures the mood of Claude Debussy's best-known composition, Clair de Lune (which means moonlight in French). The piece was published in 1905 as the third of four movements in the composer's Suite Bergamasque, and unlike the other parts of this work, Clair is quiet, contemplative, and slightly melancholy, evoking the feeling of a solitary walk through a moonlit garden.

“Moonlight” uses a digital 3D model of the Moon built from Lunar Reconnaissance Orbiter global elevation maps and image mosaics. The lighting is derived from actual Sun angles during lunar days in 2018. Enjoy and read more HERE.

The Hunt for New Worlds Continues with TESS

We're getting ready to start our next mission to find new worlds! The Transiting Exoplanet Survey Satellite (TESS) will find thousands of planets beyond our solar system for us to study in more detail. It's preparing to launch from our Kennedy Space Center at Cape Canaveral in Florida.

Once it launches, TESS will look for new planets that orbit bright stars relatively close to Earth. We're expecting to find giant planets, like Jupiter, but we're also predicting we'll find Earth-sized planets. Most of those planets will be within 300 light-years of Earth, which will make follow-up studies easier for other observatories.

TESS will find these new exoplanets by looking for their transits. A transit is a temporary dip in a star's brightness that happens with predictable timing when a planet crosses between us and the star. The information we get from transits can tell us about the size of the planet relative to the size of its star. We've found nearly 3,000 planets using the transit method, many with our Kepler space telescope. That's over 75% of all the exoplanets we've found so far!

TESS will look at nearly the entire sky (about 85%) over two years. The mission divides the sky into 26 sectors. TESS will look at 13 of them in the southern sky during its first year before scanning the northern sky the year after.

What makes TESS different from the other planet-hunting missions that have come before it? The Kepler mission (yellow) looked continually at one small patch of sky, spotting dim stars and their planets that are between 300 and 3,000 light-years away. TESS (blue) will look at almost the whole sky in sections, finding bright stars and their planets that are between 30 and 300 light-years away.

TESS will also have a brand new kind of orbit (visualized below). Once it reaches its final trajectory, TESS will finish one pass around Earth every 13.7 days (blue), which is half the time it takes for the Moon (gray) to orbit. This position maximizes the amount of time TESS can stare at each sector, and the satellite will transmit its data back to us each time its orbit takes it closest to Earth (orange).

Kepler's goal was to figure out how common Earth-size planets might be. TESS's mission is to find exoplanets around bright, nearby stars so future missions, like our James Webb Space Telescope, and ground-based observatories can learn what they're made of and potentially even study their atmospheres. TESS will provide a catalog of thousands of new subjects for us to learn about and explore.

The TESS mission is led by MIT and came together with the help of many different partners. Learn more about TESS and how it will further our knowledge of exoplanets, or check out some more awesome images and videos of the spacecraft. And stay tuned for more exciting TESS news as the spacecraft launches!

Watch the Launch!

*April 16 Update*

Launch teams are standing down today to conduct additional Guidance Navigation and Control analysis, and teams are now working towards a targeted launch of the Transiting Exoplanet Survey Satellite (TESS) on Wednesday, April 18. The TESS spacecraft is in excellent health, and remains ready for launch. TESS will launch on a Falcon 9 rocket from Space Launch Complex 40 at Cape Canaveral Air Force Station in Florida.

Largest Batch of Earth-size, Habitable Zone Planets

Our Spitzer Space Telescope has revealed the first known system of seven Earth-size planets around a single star. Three of these planets are firmly located in an area called the habitable zone, where liquid water is most likely to exist on a rocky planet.

This exoplanet system is called TRAPPIST-1, named for The Transiting Planets and Planetesimals Small Telescope (TRAPPIST) in Chile. In May 2016, researchers using TRAPPIST announced they had discovered three planets in the system.

Assisted by several ground-based telescopes, Spitzer confirmed the existence of two of these planets and discovered five additional ones, increasing the number of known planets in the system to seven.

This is the FIRST time three terrestrial planets have been found in the habitable zone of a star, and this is the FIRST time we have been able to measure both the masses and the radius for habitable zone Earth-sized planets.

All of these seven planets could have liquid water, key to life as we know it, under the right atmospheric conditions, but the chances are highest with the three in the habitable zone.

At about 40 light-years (235 trillion miles) from Earth, the system of planets is relatively close to us, in the constellation Aquarius. Because they are located outside of our solar system, these planets are scientifically known as exoplanets. To clarify, exoplanets are planets outside our solar system that orbit a sun-like star.

In this animation, you can see the planets orbiting the star, with the green area representing the famous habitable zone, defined as the range of distance to the star for which an Earth-like planet is the most likely to harbor abundant liquid water on its surface. Planets e, f and g fall in the habitable zone of the star.

Using Spitzer data, the team precisely measured the sizes of the seven planets and developed first estimates of the masses of six of them. The mass of the seventh and farthest exoplanet has not yet been estimated.

For comparison…if our sun was the size of a basketball, the TRAPPIST-1 star would be the size of a golf ball.

Based on their densities, all of the TRAPPIST-1 planets are likely to be rocky. Further observations will not only help determine whether they are rich in water, but also possibly reveal whether any could have liquid water on their surfaces.

The sun at the center of this system is classified as an ultra-cool dwarf and is so cool that liquid water could survive on planets orbiting very close to it, closer than is possible on planets in our solar system. All seven of the TRAPPIST-1 planetary orbits are closer to their host star than Mercury is to our sun.

 The planets also are very close to each other. How close? Well, if a person was standing on one of the planet’s surface, they could gaze up and potentially see geological features or clouds of neighboring worlds, which would sometimes appear larger than the moon in Earth’s sky.

The planets may also be tidally-locked to their star, which means the same side of the planet is always facing the star, therefore each side is either perpetual day or night. This could mean they have weather patterns totally unlike those on Earth, such as strong wind blowing from the day side to the night side, and extreme temperature changes.

Because most TRAPPIST-1 planets are likely to be rocky, and they are very close to one another, scientists view the Galilean moons of Jupiter – lo, Europa, Callisto, Ganymede – as good comparisons in our solar system. All of these moons are also tidally locked to Jupiter. The TRAPPIST-1 star is only slightly wider than Jupiter, yet much warmer. 

How Did the Spitzer Space Telescope Detect this System?

Spitzer, an infrared telescope that trails Earth as it orbits the sun, was well-suited for studying TRAPPIST-1 because the star glows brightest in infrared light, whose wavelengths are longer than the eye can see. Spitzer is uniquely positioned in its orbit to observe enough crossing (aka transits) of the planets in front of the host star to reveal the complex architecture of the system. 

Every time a planet passes by, or transits, a star, it blocks out some light. Spitzer measured the dips in light and based on how big the dip, you can determine the size of the planet. The timing of the transits tells you how long it takes for the planet to orbit the star.

The TRAPPIST-1 system provides one of the best opportunities in the next decade to study the atmospheres around Earth-size planets. Spitzer, Hubble and Kepler will help astronomers plan for follow-up studies using our upcoming James Webb Space Telescope, launching in 2018. With much greater sensitivity, Webb will be able to detect the chemical fingerprints of water, methane, oxygen, ozone and other components of a planet’s atmosphere.

At 40 light-years away, humans won’t be visiting this system in person anytime soon...that said...this poster can help us imagine what it would be like:

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

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

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

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

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

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

Calling us clean freaks would be an understatement.

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

And liftoff of Orion… via crane.

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

It’s really not tin foil.

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

Bake at 300° for 63 days.

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

Everyone (Even You!) Can Use Satellite Data

At NASA we’re pretty great at putting satellites and science instruments into orbit around Earth. But it turns out we’re also pretty great at showing people how to get and use all that data.

One of the top ways you can learn how to use NASA data is our ARSET program. ARSET is our Applied Remote Sensing Training program and it helps people build skills that integrate all these Earth science data into their decision making.

ARSET will train you on how to use data from a variety of Earth-observing satellites and instruments aboard the International Space Station.

Once you take a training, you’ll be in GREAT company because thousands of people have taken an ARSET training.

We hold in person and online trainings to people around the world, showing them how to use NASA Earth science data. Trainings are offered in air quality, climate, disaster, health, land, water resources and wildfire management.

For example, if you’re trying to track how much fresh drinking water there is in your watershed, you can take an ARSET training and learn how to find satellite data on how much precipitation has fallen over a certain time period or even things like the ‘moistness’ of soil and the quality of the water.

Best yet, all NASA Earth observing data is open and freely available to the whole world! That’s likely one of the reasons we’ve had participants from 172 of the approximately 190 countries on Earth.

Since its beginning 10 years ago, ARSET has trained more than 30 thousand people all over the world. They’ve also worked with people from more than 7,500 different organizations and that includes government agencies, non-profit groups, advocacy organizations, private industry.

And even though 2019 is ARSET’s 10th birthday – we’ve only just begun. Every year about 60% of the organizations and agencies we train are new to the program. We’re training just about anyone who is anyone doing Earth science on Earth! 

Join us, learn more about how we train people to use Earth observing data here, and heck, you can even take a training yourself: https://arset.gsfc.nasa.gov/.
