Virginia Middle-Schooler Takes Grand Prize at NASA Langley Student Art Contest

Anna Fox, a seventh-grader from Virginia Beach Middle School in Virginia Beach, Virginia, was named as the grand prize winner of Langley Research Center’s Student Art Contest.

“I was very excited when I heard that I won first place for my grade,” Anna said. “But when I heard that I won grand prize, I was speechless.”

A record 831 entries were submitted from hundreds of children in 39 states, the District of Columbia and Puerto Rico, with 13 students earning first-place honors in grade levels K-12 and the opportunity to be considered for the grand prize, said Kristina Cors, Langley Student Art Contest coordinator.

“We hope this contest continues to grow and provide a place for students to explore science and technology through creativity,” she said.

“I was very excited when I heard that I won first place for my grade,” Anna Fox said. “But when I heard that I won grand prize, I was speechless.”

The art contest theme, “The Next 100 Years,” was intended to illustrate how NASA research and innovation propels science to new discoveries.

“This year’s artwork was particularly remarkable, and represented the theme ‘The Next 100 Years’ with imagination and immense talent,” Cors said.

Anna’s winning piece shows a deep-space scene with an astronaut planting a flag on a planet’s mountain while watching a rocket fly off in the distance in a sky populated by stars, galaxies and a moon.

“When I started drawing, I had no idea what to do, so I had looked at a bunch of videos on how to do galaxies for inspiration,” Anna said. “After that I randomly placed colors together until I found something I liked. It all started coming together from there.”

Once she got an idea in motion, Anna did her work using old and new techniques.

“I created my artwork digitally on Photoshop,” Anna said. “I had started with basic colors for the background, including the explosion behind the rocks. Then, on another layer I created the rocks, planet, astronaut and rocket ship taking off. Later I added detail on all the layers to look more realistic. The last step was to add all of the stars and galaxies, which I did with a special brush.”

Anna, who has been an artist for as long as she could pick up a pencil, said she started drawing digitally when she was 11, inspired by her father’s work on a computer.

“I think the best part of creating art is having fun with it and inspiring others to do art as well,” she said.

Anna said she always had an interest in space and the art contest was a perfect vehicle to express that.

“I think that the coolest thing about NASA is that they help so many people achieve their dreams, and send people to do what not a lot of people get to do,” Anna said.

For her grand-prize victory, Anna received a certificate, and a NASA Exploration Package of posters, pens, stickers, patches and lapel pins. Her artwork will be displayed at the Virginia Air & Space Center in Hampton, Virginia.

The 13 grade-level winners were selected by a panel of five judges from the Hampton Roads art community, and the grand champion was picked by Langley employees. Each piece was evaluated on originality, interpretation of subject matter/theme, creative techniques, composition and overall art appearance.

Orion Launch Abort System Motor Gets Fired-up About the Journey to Mars

Applause resounded from NASA and its partners as they watched Orion’s jettison motor generate 40,000 pounds of thrust in just a blink of an eye, preparing the spacecraft for its first integrated mission with the Space Launch System rocket.  

Onlookers had just witnessed a 1.5-second jettison motor test firing at Aerojet Rocketdyne’s facility in Sacramento, California.

The Orion launch abort system (LAS) is designed to protect astronauts in the unlikely event there is an issue during launch by pulling the spacecraft away from the rocket during a mission. The jettison motor is activated during ascent to separate the launch abort system from the spacecraft after it is no longer needed during a mission.

“This test showed us that the jettison motor can quickly generate the amount of thrust needed to pull the LAS away during an Orion mission,” said Tim Larson, jettison motor principle engineer for Lockheed Martin who has been with the project since inception. “I’m very pleased with how the test went.”

The fifth firing

The jettison motor has now undergone five tests, including two test flights. Each test in the series builds upon each other, moving the nation forward on its journey to Mars.

The motor used for the fifth test was rebuilt from a previous test motor.

“We were able to recycle some of the parts from the second ground test and use it for this test,” said NASA LAS project manager Robert Decoursey. “We not only went green, but we also saved money.”

Inside and around the test motor were instruments that included strain gauges, accelerometers and pressure transducers, which feed engineers high-quality data that show whether the motor design is ready for upcoming flight tests and missions. This motor had more instruments and produced more data than any of the previous tests.

“There are many intricate details in the jettison motor design that are not obvious from the outside, and the consistent orchestration of those details are most important to obtain predictable performance,” said NASA LAS deputy project manager Deborah Crane. “Aerojet Rocketdyne has done an excellent job executing this test on schedule.”

The jettison motor bakery

Creating a jettison motor is like baking two big cakes and making enough batter for some leftover cupcakes, according to Tim Warner, NASA LAS business manager.

What’s most exciting for the team, besides the successful test, are the latest upgrades to their baking and mixing tools.

“We were using two mixing batches to make just one motor, but have recently upgraded to a larger mixing bowl, saving us time and money,” Decoursey said.

The new mixing bowl can hold up to 450 whopping gallons of cake batter, or in NASA terms, motor propellant.

The team mixes up the batter in this large mixing bowl and evenly splits the batter into two pots for a perfectly sculpted jettison motor.

Any leftover propellant is used to make small test motors. The smaller motors are used to check the propellant’s combustion capabilities before the motors are accepted for test or flight.

What’s next?

NASA and its partners are expected to perform the last flight test of the launch abort system in 2019 before they begin sending crew to deep space aboard Orion. During the final test, an uncrewed Orion capsule will launch from a modified Peacekeeper missile and demonstrate a successful abort under the highest aerodynamic loads it could experience during a mission.

The jettison motor will be used during Orion’s first integrated mission with SLS, known as Exploration Mission-1 (EM-1) in late 2018. The mission will be the second test flight for Orion, and the first for SLS. EM-1 will send Orion on a three-week journey approximately 40,000 miles beyond the moon. The test will demonstrate the integrated performance of the rocket and spacecraft before their second test flight together, Exploration Mission-2, which will carry crew.

The LAS is led out NASA’s Langley Research Center in Virginia in collaboration with NASA’s Marshall Space Flight Center in Alabama.

NASA’s Transiting Exoplanet Survey Satellite (TESS) 

The Transiting Exoplanet Survey Satellite (TESS) is the next step in the search for planets outside of our solar system, including those that could support life. The mission will find exoplanets that periodically block part of the light from their host stars, events called transits. 

 TESS will survey 200,000 of the brightest stars near the sun to search for transiting exoplanets. The mission is scheduled to launch in 2018.  

The TESS launch date is NLT June 2018 (the current working launch date is April 2018).

At Langley, Admiration and Gratitude Multiply on Katherine Johnson’s 100th Birthday

When Jasmine Byrd started her job at NASA about two years ago, she knew nothing about Katherine Johnson, the mathematician and “human computer” whose achievements helped inspire the book and movie “Hidden Figures.”

At that point, the release of the film was still months away. But excitement was building — particularly at Byrd’s new workplace. She’d arrived at NASA’s Langley Research Center in Hampton, Virginia, where Johnson spent her entire, 33-year NACA and NASA career.

Soon, Byrd felt a strong connection to a woman she’d never met, nearly 70 years her senior.

“I was just enthralled with her story,” said Byrd, a project coordinator for NASA’s Convergent Aeronautics Solutions Project. Today, she works inside Langley’s Building 1244, the same hangar-side location where Johnson crunched numbers for the Flight Research Division in the 1950s.

“I am thankful for the bridge that Katherine built for someone like myself to easily walk across,” Byrd said. “It helps me to not take this opportunity for granted. I know there were people before me who put in a lot of work and went through a lot of turmoil at times to make sure it was easier for people like myself.”

Fountain of gratitude

As Katherine G. Johnson’s 100th birthday — Aug. 26 — approached, many Langley employees expressed admiration for the woman whose math powered some of America’s first triumphs in human space exploration.

Johnson did trajectory analysis for Alan Shepard’s May 1961 mission Freedom 7, America’s first human spaceflight. At a time when digital computers were relatively new and untested, she famously checked the computer’s math for John Glenn’s historic first orbital spaceflight by an American in February of 1962.

Those are just two bullet points in a brilliant career that stretched from 1953 to 1986.

Her 100th birthday was recognized throughout NASA and around the world. But at Langley, the milestone created an extra measure of pride and joy.

Graduate research assistant Cecilia Stoner, stopped on her way to Langley’s cafeteria, said she admires how Johnson remained humble — even when showered with accolades ranging from the Presidential Medal of Freedom to toys made in her likeness.

Stoner’s lunch companion, Erin Krist, chimed in. “It’s incredible what she managed to do,” said Krist, a summer intern. “She paved the way for women. We couldn’t work here today if that hadn’t happened.”

Langley’s acting chief technologist, Julie Williams-Byrd, echoed that thought.

“She opened the doors for the rest of us,” Williams-Byrd said. “Between her and Dorothy Vaughan and Mary Jackson and all the women who were at Langley at the time. It didn’t matter if they were called computers in skirts. They were here to do a job.

“It’s typical NASA culture, right?” Williams-Byrd said. “We have a mission. Everybody’s going to jump in and do what they can to make that mission successful.”

She also admires Johnson’s devotion to promoting science, technology, engineering and math studies among young people.

“While she was very focused on the technical work and really did great things there, her balance of life and responsibilities to those who would come up behind her, that really resonates with me,” Williams-Byrd said.

A modest mentor

Remarkably, a handful of current Langley employees worked side by side with Johnson. Among them is research mathematician Daniel Giesy, who started at the center in 1977.

“On my first job here, I was teamed with Katherine Johnson,” Giesy said. “She mentored me.”

Johnson showed Giesy the ropes as he and Johnson both provided mathematical and computer programming support for researchers working to find new tools for designing aircraft control systems. They eventually coauthored papers including “Application of Multiobjective Optimization in Aircraft Control Systems Design” from 1979, written with Dan Tabak.

“I would describe her as a good colleague, competent, courteous,” Giesy said. “She had her moments. If you slopped coffee on the way back from the break room, you bloody well better clean up after yourself. You don’t leave it for the janitor staff to work on.

“But she was focused on getting the job done,” Giesy said. “At that point in time, she wasn’t resting on laurels.” Only later would Giesy learn of her historic contributions to early space missions. “She did not brag on herself particularly.”

Regina Johns, who today recruits participants for tests related to crew systems, aviation operations and acoustics, arrived at Langley in 1968 as a high school intern. She returned as a contract employee in 1973 and has worked at Langley ever since.

In those early days, she remembers running into Johnson on campus occasionally. Johnson would often stop and talk, asking about her plans and what she was working on. Johns would eventually get to know Mary Jackson, another Langley researcher central to the “Hidden Figures” story.

“There weren’t a lot of minorities here at that time,” Johns said. “To know that they were engineers and mathematicians, it just gave me hope that, if they can do it, it can be done. If you work hard, you can do it.”

She, like many across the agency, said she’d like to send Johnson a birthday message.

“If I had a chance, I would say, thank you for setting the pathway for young people. Thank you for showing us that we can do anything.”

Enduring legacy

In terms of lives touched, Johnson’s work with youth stands alongside her impact as a world-class mathematician. Langley’s Katherine G. Johnson Computational Research Facility, which opened in September 2017, offers a physical reminder of her contributions.

“The Katherine Johnson building is near where I work, so I think about her often,” said Kimberly Bloom, director of Langley’s Child Development Center. Johnson’s life and accomplishments would have deserved attention even if Hollywood hadn’t come calling, she suggests.

“It’s an important story — how she empowered women of all races,” Bloom said. “And she encouraged kids to learn. She influenced culture here at NASA, but also beyond and made an impact. She certainly is a role model.

“I’d like to thank her for all she’s done not only for NASA but also for this country,” Bloom said.

The Future of Monitoring Air Quality from Space

TEMPO’s measurements from geostationary orbit (GEO) will create a revolutionary dataset that provides understanding and improves prediction of air quality (AQ) and climate forcing.

The KORUS-AQ airborne science experiment taking to the field in South Korea this spring is part of a long-term, international project to take air quality observations from space to the next level and better inform decisions on how to protect the air we breathe.

Before a new generation of satellite sensors settle into orbit, field missions like KORUS-AQ provide opportunities to test and improve the instruments using simulators that measure above and below aircraft, while helping to infer what people breathe at the surface.

“We want to move beyond forecasting air pollution, we want to influence strategies to improve it,” said Jim Crawford, a lead scientist at NASA’s Langley Research Center in Hampton, Virginia. “This is where satellite observations can play an important role.”

Existing low Earth orbit (LEO) instruments have established the benefit of space-based views of air pollution. From space, large areas can be viewed consistently, whereas from the ground only discrete (often single) points can be measured. As Dave Flittner, TEMPO project scientist, explains, a geostationary (GEO) air-quality constellation can accurately track the import and export of air pollution as it is transported by large-scale weather patterns.

TEMPO, or Tropospheric Emissions: Monitoring of Pollution, is one instrument on the road to improving air quality from space. According to Flittner, hardware has recently begun development and TEMPO is on track to be finished no later than fall of 2017, and available for launch on a to be selected commercial communications satellite.

For the first time, TEMPO will make accurate hourly daytime measurements of tropospheric pollutants (specifically ozone, nitrogen dioxide, sulfur dioxide, formaldehyde, and aerosols) with high resolution over the U.S., Canada and Mexico. With help from related international missions, these observations provide a complete picture of pollution sources in the northern hemisphere and how they influence air quality from local to global scales.

These geostationary instruments will make up a northern hemisphere air quality constellation to analyze their respective regions.

About 22,000 miles above the equator, the Korean Aerospace Research Institute’s GEMS (The Geostationary Environmental Monitoring Spectrometer), the European Space Agency’s Sentinel-4/UVN, and NASA’s TEMPO, will maintain their positions in orbit as the Earth rotates, covering a majority of the area from East Asia through greater North America and Europe. Together, these instruments will make up a northern hemisphere air quality constellation.. All three of these instruments analyze the same pollutant concentrations in their respective region, from the morning to evening.

Another critical part of the global air quality constellation are the LEO instruments, such as TROPOMI (a.k.a. Sentinel-5P), which will launch in late 2016 and provide a common reference for the three GEO sensors, allowing for a more accurate assessment of air quality within each region.

NASA Camera Shows Moon Crossing Face of Earth for 2nd Time in a Year

For only the second time in a year, a NASA camera aboard the Deep Space Climate Observatory (DSCOVR) satellite captured a view of the moon as it moved in front of the sunlit side of Earth. 

The images were captured by NASA’s Earth Polychromatic Imaging Camera (EPIC), a four-megapixel CCD camera and telescope on the DSCOVR satellite orbiting 1 million miles from Earth. From its position between the sun and Earth, DSCOVR conducts its primary mission of real-time solar wind monitoring for the National Oceanic and Atmospheric Administration (NOAA).

The first image is from July 2016 and the second image (moon traveling diagonally Northeast in the image) is from July 2015
