Everyone (Even You!) Can Use Satellite Data

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.

image

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.

image

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.

image

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.

image

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/.

Watch Mercury Transit the Sun on Nov. 11

On Nov. 11, Earthlings will be treated to a rare cosmic event — a Mercury transit.

image

For about five and a half hours on Monday, Nov. 11 — from about 7:35 a.m. EST to 1:04 p.m. EST — Mercury will be visible from Earth as a tiny black dot crawling across the face of the Sun. This is a transit and it happens when Mercury lines up just right between the Sun and Earth.

Mercury transits happen about 13 times a century. Though it takes Mercury only about 88 days to zip around the Sun, its orbit is tilted, so it's relatively rare for the Sun, Mercury and Earth to line up perfectly. The next Mercury transit isn't until 2032 — and in the U.S., the next opportunity to catch a Mercury transit is in 2049!

How to watch

Our Solar Dynamics Observatory satellite, or SDO, will provide near-real time views of the transit. SDO keeps a constant eye on the Sun from its position in orbit around Earth to monitor and study the Sun's changes, putting it in the front row for many eclipses and transits.

Visit mercurytransit.gsfc.nasa.gov to tune in!

image

Our Solar Dynamics Observatory also saw Mercury transit the Sun in 2016.

If you're thinking of watching the transit from the ground, keep in mind that it is never safe to look directly at the Sun. Even with solar viewing glasses, Mercury is too small to be easily seen with the unaided eye. Your local astronomy club may have an opportunity to see the transit using specialized, properly-filtered solar telescopes — but remember that you cannot use a regular telescope or binoculars in conjunction with solar viewing glasses.

Transits in other star systems

Transiting planets outside our solar system are a key part of how we look for exoplanets.

Our Transiting Exoplanet Survey Satellite, or TESS, is NASA’s latest planet-hunter, observing the sky for new worlds in our cosmic neighborhood. TESS searches for these exoplanets, planets orbiting other stars, by using its four cameras to scan nearly the whole sky one section at a time. It monitors the brightness of stars for periodic dips caused by planets transiting those stars.

image

This is similar to Mercury’s transit across the Sun, but light-years away in other solar systems! So far, TESS has discovered 29 confirmed exoplanets using transits — with over 1,000 more candidates being studied by scientists!

Our Eight Favorite Things About This Weekend’s Student Launch

We’re ready for another year of sky-high fun, literally, as student teams launch nearly 50 high-powered rockets during the 16th annual Student Launch, April 16, near NASA’s Marshall Space Flight Center in Huntsville, Alabama.

image

Hundreds of students from high schools, colleges and universities across 22 states have spent the past several months designing, fabricating and testing single-stage rockets and autonomous ground support systems. So, what makes this event so great? Start here to find out as we list our eight favorite things.

1. A Mile-High Target

Our Eight Favorite Things About This Weekend’s Student Launch

Setting goals is a part of life, and so, too, is this competition. Teams will attempt to launch their rocket to an altitude of one mile, or 5,280 feet. That'll earn the maximum number of altitude points of 5,280. But, if teams go over or under, there's a penalty. Teams lose 2 points for every foot over and 1 point for every foot under.

2. Return of the Mars Ascent Vehicle Challenge

image

Back for a second consecutive year – the MAV challenge runs parallel with Student Launch -- requiring teams to design an autonomous system capable of retrieving and storing a mock Martian sample into their rocket. Sponsored by the Centennial Challenges program – our citizen prize program -- MAV focuses on designing rockets for future sample return missions to Mars.

3. Why, Yes, It Really Is Rocket Science

image

Static stability margin, thrust-to-weight ratios and ammonium perchlorate composite propellants may seem like a foreign language, but it’s just everyday lingo for these young rocket scientists. In addition to designing and fabricating a rocket, students hone skills by completing electrical wiring and operating computer-aided software for launching rockets and analyzing payloads.

4. Putting Rocketry Skills to the Test

image

During launch week, we host a “Rocket Fair,” where each team gives a technical presentation about their rocket and any autonomous systems, to hundreds of engineers and team members from NASA, corporate sponsor Orbital ATK of Promontory, Utah, and the media. Doing so provides students an opportunity to gain valuable feedback from real rocket scientists and engineers.

5. Hard Work Pays Off, Literally

image

Yes, a year’s worth of bragging rights are on the line, but so, too, is some cold, hard cash. Orbital ATK offers an overall cash prize of $5,000 to the highest-ranking college/university team to meet the Student Launch objectives. Plus, the MAV challenge offers a share of $50,000 for completion of its objectives.

6. Safety, Safety and More Safety

image

Teams complete a lengthy series of comprehensive flight and safety reviews, all overseen by our staff, engineers and scientists. Multiple reviews are scheduled throughout the 8-month-long design process, as well as during the launch week at Marshall Space Flight Center. These reviews mirror the engineering design lifecycle used by our workforce.

7. Celebrate Good Times

image

After the smoke clears from rocket launches, teams gather for a well-earned evening of celebration. The awards banquet -- held at the U.S. Space & Rocket Center in Huntsville, Alabama, and funded by Orbital ATK -- recognizes teams with awards including Best Design, Altitude, Safety and more.

8. Teams Make Dreams Come True

image

More than just a friendly competition, Student Launch and MAV Challenge provide long-lasting life experiences outside of the classroom. Students benefit from working as a team, applying STEM skills and overcoming technical obstacles -- all aspects related to the success of our work. 

The MAV Challenge and Student Launch are open to the public and will stream live on line at: http://www.ustream.tv/channel/nasa-msfc

NASA Inspires Your Crafty Creations for World Embroidery Day

It’s amazing what you can do with a little needle and thread! For #WorldEmbroideryDay, we asked what NASA imagery inspired you. You responded with a variety of embroidered creations, highlighting our different areas of study.

Here’s what we found:

Webb’s Carina Nebula

hThis embroidered image shows the Carina Nebula captured by the James Webb Space Telescope. The image is framed in black. At the center a circular piece of art appears outlined in white. At the top of the circle, the thread is dark blue on the left. As you travel down white stars appear in lighter shades of blue. In the middle threads turn to dark black, red and orange to signify the nebula’s gas-like structure.

Wendy Edwards, a project coordinator with Earth Science Data Systems at NASA, created this embroidered piece inspired by Webb’s Carina Nebula image. Captured in infrared light, this image revealed for the first time previously invisible areas of star birth. Credit: Wendy Edwards, NASA. Pattern credit: Clare Bray, Climbing Goat Designs

Wendy Edwards, a project coordinator with Earth Science Data Systems at NASA, first learned cross stitch in middle school where she had to pick rotating electives and cross stitch/embroidery was one of the options.  “When I look up to the stars and think about how incredibly, incomprehensibly big it is out there in the universe, I’m reminded that the universe isn’t ‘out there’ at all. We’re in it,” she said. Her latest piece focused on Webb’s image release of the Carina Nebula. The image showcased the telescope’s ability to peer through cosmic dust, shedding new light on how stars form.

Ocean Color Imagery: Exploring the North Caspian Sea

This image shows an embroidery piece inspired by NASA imagery. The background is white. In the middle, a brown frame appears holding an illustration of the Caspian Sea. To the bottom left, blue, green and light green sea appears showing water moving. To the top right, ice gouges are designed in brown and white.

Melissa Cole is an award-winning fiber artist from Philadelphia, PA, USA, inspired by the beauty and vastness of the universe. They began creating their own cross stitch patterns at 14, while living with their grandparents in rural Michigan, using colored pencils and graph paper.  The Pillars of Creation (Eagle Nebula, M16), released by the Hubble Telescope in 1995 when Melissa was just 11 years old, captured the imagination of a young person in a rural, religious setting, with limited access to science education.

This artistic piece shows two images of the Pillars of Creation captured by the Hubble Space Telescope. To the left, the circular art piece is on a brown background. The nebula is blue and navy with small white stitches showing stars. In the center, there are three pillars that appear colored in dark red, yellow and light green.  The pillars look like arches and spires rising out of a desert landscape, but are filled with semi-transparent gas and dust, and ever changing. To the right is a closeup of one of the pillars. The image is colored in red, yellow and brown thread, felt and wool. In the middle, blue wool appears showing space. A white star appears in the upper left.

Lauren Wright Vartanian of Guelph, Ontario Canada considers herself a huge space nerd. She’s a multidisciplinary artist who took up hand sewing after the birth of her daughter. She’s currently working on the illustrations for a science themed alphabet book, made entirely out of textile art. It is being published by Firefly Books and comes out in the fall of 2024. Lauren said she was enamored by the original Pillars image released by Hubble in 1995. When Hubble released a higher resolution capture in 2015, she fell in love even further! This is her tribute to those well-known images.

James Webb Telescope Captures Pillars of Creation

This rectangular piece shows another embroidered interpretation of the Pillars of Creation captured by the Webb Telescope last year. The background is blue and black with white stars scattered from top to bottom. In the middle, three pillars appear in colors of red and yellow. The pillars, which lean to the right, continue downward to the left of the art piece. Credit: Darci Lenker of Darci Lenker Art

Darci Lenker of Norman, Oklahoma started embroidery in college more than 20 years ago, but mainly only used it as an embellishment for her other fiber works. In 2015, she started a daily embroidery project where she planned to do one one-inch circle of embroidery every day for a year.  She did a collection of miniature thread painted galaxies and nebulas for Science Museum Oklahoma in 2019. Lenker said she had previously embroidered the Hubble Telescope’s image of Pillars of Creation and was excited to see the new Webb Telescope image of the same thing. Lenker could not wait to stitch the same piece with bolder, more vivid colors.

Milky Way

This image shows an illustration of the Milky Way Galaxy. The round frame is black and circular. As you move inward, a white dotted pattern appears. Continuing to the center, a black background appears with white dots showing stars.  Five rings appear in a circular motion colored in threads of blue white and red. The center of the Milky Way Galaxy is white and oval shaped. Credit: Darci Lenker/Darci Lenker Art

Darci Lenker of Darci Lenker Art was inspired by NASA’s imaging of the Milky Way Galaxy. Credit: Darci Lenker

In this piece, Lenker became inspired by the Milky Way Galaxy, which is organized into spiral arms of giant stars that illuminate interstellar gas and dust. The Sun is in a finger called the Orion Spur.

The Cosmic Microwave Background

This image shows an embroidery design based on the cosmic microwave background, created by Jessica Campbell, who runs Astrostitches. Inside a tan wooden frame, a ccolorful oval is stitched onto a black background in shades of blue, green, yellow, and a little bit of red. Credit: Jessica Campbell/Astrostitches

Jessica Campbell obtained her PhD in astrophysics from the University of Toronto studying interstellar dust and magnetic fields in the Milky Way Galaxy. Jessica promptly taught herself how to cross-stitch in March 2020 and has since enjoyed turning astronomical observations into realistic cross-stitches. Her piece was inspired by the cosmic microwave background, which displays the oldest light in the universe.

This image shows the oldest light in the universe, the cosmic microwave background, captured by the Wilkinson Microwave Anisotropy Probe, also known as WMAP. At the center of the image is a colorful oval that is speckled with the seeds of galaxies, which appear as blobs of dark blue, light blue, green, yellow, and a little bit of red.

GISSTEMP: NASA’s Yearly Temperature Release

This image shows an embroidered art piece based on NASA’s yearly temperature release. To the bottom left, two fingers hold up the circular piece. A round wooden frame holds it in place. In the center, a map appears of the different content. It’s outlined in black. Most of the map is covered in yellow stitching to show a warming pattern. To the left and right, the stitches change to an orange color and are scattered on the map. In the top left- and right-hand corners, the color changes to a dark red to signify another temperature change.

Katy Mersmann, a NASA social media specialist, created this embroidered piece based on NASA’s Goddard Institute for Space Studies (GISS) global annual temperature record. Earth’s average surface temperature in 2020 tied with 2016 as the warmest year on record. Credit: Katy Mersmann, NASA

Katy Mersmann is a social media specialist at NASA’s Goddard Space Flight Center in Greenbelt, Md. She started embroidering when she was in graduate school. Many of her pieces are inspired by her work as a communicator. With climate data in particular, she was inspired by the researchers who are doing the work to understand how the planet is changing. The GISTEMP piece above is based on a data visualization of 2020 global temperature anomalies, still currently tied for the warmest year on record.

In addition to embroidery, NASA continues to inspire art in all forms. Check out other creative takes with Landsat Crafts and the James Webb Space telescope public art gallery.

Top 10 Things to Know for the Return of our Launch America Mission With SpaceX

image

History was made May 30 when NASA astronauts Robert Behnken and Douglas Hurley launched from American soil in a commercially built and operated American crew spacecraft on its way to the International Space Station. 

Pictured above is the SpaceX Dragon Endeavour spacecraft that lifted off on the company’s Falcon 9 rocket from Launch Complex 39A at Kennedy Space Center in Florida and docked with the space station on May 31. Now, Behnken and Hurley are ready to return home in Endeavour for a splashdown off the coast of Florida, closing out a mission designed to test SpaceX’s human spaceflight system, including launch, docking, splashdown, and recovery operations. Undocking is targeted for 7:34 p.m. ET on August 1, with splashdown back to Earth slated for 2:42 p.m. on August 2. Watch our continuous live coverage HERE. 

1. Where will Behnken and Hurley splash down?

image

Image: SpaceX’s Crew Dragon is guided by four parachutes as it splashes down in the Atlantic on March 8, 2019, after the uncrewed spacecraft's return from the International Space Station on the Demo-1 mission.

Together with SpaceX, we are capable of supporting seven splashdown sites off the coast of Florida. The seven potential splashdown sites for the Dragon Endeavor are off the coasts of Pensacola, Tampa, Tallahassee, Panama City, Cape Canaveral, Daytona, and Jacksonville.

2. How will a splashdown location be chosen?

Splashdown locations are selected using defined priorities, starting with selecting a station departure date and time with the maximum number of return opportunities in geographically diverse locations to protect for weather changes. Teams also prioritize locations which require the shortest amount of time between undocking and splashdown based on orbital mechanics, and splashdown opportunities that occur in daylight hours.

Check out the Departure and Splashdown Criteria Fact Sheet for an in-depth look at selecting return locations, decision points during return, and detailed weather criteria.

3. How long will it take for Behnken and Hurley to return to Earth?

image

Return time for Behnken and Hurley will vary depending on the undock and splashdown opportunities chosen, with the primary opportunity taking between six and 30 hours.

4. What does the return look like? What are the major milestones?

image

Crew Dragon’s return home will start with undocking from the International Space Station. At the time of undock, Dragon Endeavour and its trunk weigh approximately 27,600 pounds. We will provide live coverage of the return from undocking all the way through splashdown.

There will be two very small engine burns immediately after hooks holding Crew Dragon in place retract to actually separate the spacecraft from the station. Once flying free, Dragon Endeavour will autonomously execute four departure burns to move the spaceship away from the space station and begin the flight home. Several hours later, one departure phasing burn, lasting about six minutes, puts Crew Dragon on the proper orbital path to line it up with the splashdown zone.

Shortly before the final deorbit burn, Crew Dragon will separate from its trunk, which will burn up in Earth’s atmosphere. The spacecraft then executes the deorbit burn, which commits Crew Dragon to return and places it on an orbit with the proper trajectory for splashdown. After trunk separation and the deorbit burn are complete, the Crew Dragon capsule weighs approximately 21,200 pounds.  

5. How fast will Dragon Endeavour be going when it re-enters the Earth’s atmosphere? How hot will it get?

Crew Dragon will be traveling at orbital velocity prior to re-entry, moving at approximately 17,500 miles per hour. The maximum temperature it will experience on re-entry is approximately 3,500 degrees Fahrenheit. The re-entry creates a communications blackout between the spacecraft and Earth that is expected to last approximately six minutes.

6. When do the parachutes deploy?

image

Image: SpaceX’s final test of Crew Dragon’s Mark 3 parachute system on Friday, May 1, 2020, that will be used during the Demo-2 splashdwon mission. 

Dragon Endeavour has two sets of parachutes will that deploy once back inside Earth’s atmosphere to slow down prior to splashdown. Two drogue parachutes will deploy at about 18,000 feet in altitude while Crew Dragon is moving approximately 350 miles per hour. Four main parachutes will deploy at about 6,000 feet in altitude while Crew Dragon is moving approximately 119 miles per hour.

7. Who recovers the crew and the Dragon Endeavour capsule from the water? What vehicles and personnel are involved?

image

Image: SpaceX’s Crew Dragon is loaded onto the company’s recovery ship, Go Searcher, in the Atlantic Ocean, about 200 miles off Florida’s east coast, on March 8, after returning from the International Space Station on the Demo-1 mission.Credits: SpaceX

For splashdown at any of the seven potential sites, SpaceX personnel will be on location to recover the capsule from the water. Two recovery ships, the Go Searcher and the Go Navigator, split locations between the Gulf of Mexico and the Atlantic Ocean off the coast of Florida. On either ship will be more than 40 personnel from SpaceX and NASA, made up of spacecraft engineers, trained water recovery experts, medical professionals, the ship’s crew, NASA cargo experts, and others to assist in the recovery.

8. How long after splashdown until Behnken and Hurley are out of the capsule?

image

Image: NASA astronaut Doug Hurley, along with teams from NASA and SpaceX, rehearse crew extraction from SpaceX’s Crew Dragon, on August 13, 2019. Credits: NASA/Bill Ingalls

Immediately after splashdown has occurred, two fast boats with SpaceX personnel deploy from the main recovery ship. The first boat checks capsule integrity and tests the area around the Crew Dragon for the presence of any hypergolic propellant vapors. Once cleared, the personnel on the boats begin preparing the spaceship for recovery by the ship. The second fast boat is responsible for safing and recovering Crew Dragon’s parachutes, which have at this point detached from the capsule and are in the water.

At this point the main recovery vessel can move in and begin to hoist the Crew Dragon capsule onto the main deck. Once the capsule is on the recovery vessel, it is moved to a stable location for the hatch to be opened for waiting medical professionals to conduct initial checks and assist Behnken and Hurley out of Dragon Endeavour.

This entire process is expected to take approximately 45 to 60 minutes, depending on spacecraft and sea state conditions.

9. Where do Behnken and Hurley go after they are out of the capsule?

Immediately after exiting the Crew Dragon capsule, Behnken and Hurley will be assisted into a medical area on the recovery ship for initial assessment. This is similar to procedures when welcoming long-duration crew members returning home on Soyuz in Kazakhstan.

After initial medical checks, Behnken and Hurley will be returned to shore either by traveling on the primary recovery ship or by helicopter. Helicopter returns from the recovery ship are the baseline for all splashdown zones except for the Cape Canaveral splashdown site, with travel times ranging from approximately 10 minutes to 80 minutes. The distance from shore will be variable depending on the splashdown location, ranging from approximately 22 nautical miles to 175 nautical miles.

Once returned to shore, both crew members will immediately board a waiting NASA plane to fly back to Ellington field in Houston.

10. What happens next?

Meanwhile, Dragon Endeavour will be returned back to the SpaceX Dragon Lair in Florida for inspection and processing. Teams will examine the data and performance of the spacecraft throughout the test flight to complete the certification of the system to fly operational missions for our Commercial Crew and International Space Station Programs. The certification process is expected to take about six weeks. Following successful certification, the first operational mission will launch with Crew Dragon commander Michael Hopkins, pilot Victor Glover, and mission specialist Shannon Walker – all of NASA – along with Japan Aerospace Exploration Agency (JAXA) mission specialist Soichi Noguchi will launch on the Crew-1 mission from Launch Complex 39A at NASA’s Kennedy Space Center in Florida. The four crew members will spend six months on the space station.

The launch is targeted for no earlier than late-September.
