By the end of the year, over 70 different models had been tested by facilities at the Air Force's Arnold Engineering Development Center and the NASA Langley, Ames, and Lewis Research Centers.
Here at NASA Langley Research Center, a lot of those tests took place in our 7 X 10-Foot High Speed Tunnel (pictured above).
Some tests also took place in our 20-Foot Vertical Spin Tunnel.
Engineers at NASA’s Langley Research Center in Hampton, Virginia, kicked off a series of nine drop tests of a representative Orion crew capsule withcrash test dummies inside to understand what the spacecraft and astronauts may experience when landing in the Pacific Ocean after deep-space missions. The high-fidelity capsule, coupled with the heat shield from Orion’s first flight in space, was hoisted approximately 16 feet above the water and vertically dropped into Langley’s 20-foot-deep Hydro Impact Basin. The crash test dummies were instrumented to provide data and secured inside the capsule to help provide information engineers need to ensure astronauts will be protected from injury during splashdown. Each test in the series simulates different scenarios for Orion’s parachute-assisted landings, wind conditions, velocities and wave heights the spacecraft may experience when touching down in the ocean.
In June 2015, when the cameras on NASA’s approaching New Horizons spacecraft first spotted the large reddish polar region on Pluto’s largest moon, Charon, mission scientists knew two things: they’d never seen anything like it elsewhere in our solar system, and they couldn’t wait to get the story behind it.
Over the past year, after analyzing the images and other data that New Horizons has sent back from its historic July 2015 flight through the Pluto system, the scientists think they’ve solved the mystery. As they detail this week in the international scientific journal Nature, Charon’s polar coloring comes from Pluto itself – as methane gas that escapes from Pluto’s atmosphere and becomes “trapped” by the moon’s gravity and freezes to the cold, icy surface at Charon’s pole. This is followed by chemical processing by ultraviolet light from the sun that transforms the methane into heavier hydrocarbons and eventually into reddish organic materials called tholins.
"Who would have thought that Pluto is a graffiti artist, spray-painting its companion with a reddish stain that covers an area the size of New Mexico?" asked Will Grundy, a New Horizons co-investigator from Lowell Observatory in Flagstaff, Arizona, and lead author of the paper. "Every time we explore, we find surprises. Nature is amazingly inventive in using the basic laws of physics and chemistry to create spectacular landscapes."
The team combined analyses from detailed Charon images obtained by New Horizons with computer models of how ice evolves on Charon’s poles. Mission scientists had previously speculated that methane from Pluto’s atmosphere was trapped in Charon’s north pole and slowly converted into the reddish material, but had no models to support that theory.
The New Horizons team dug into the data to determine whether conditions on the Texas-sized moon (with a diameter of 753 miles or 1,212 kilometers) could allow the capture and processing of methane gas. The models using Pluto and Charon’s 248-year orbit around the sun show some extreme weather at Charon’s poles, where 100 years of continuous sunlight alternate with another century of continuous darkness. Surface temperatures during these long winters dip to -430 Fahrenheit (-257 Celsius), cold enough to freeze methane gas into a solid.
“The methane molecules bounce around on Charon's surface until they either escape back into space or land on the cold pole, where they freeze solid, forming a thin coating of methane ice that lasts until sunlight comes back in the spring,” Grundy said. But while the methane ice quickly sublimates away, the heavier hydrocarbons created from it remain on the surface.
The models also suggested that in Charon’s springtime the returning sunlight triggers conversion of the frozen methane back into gas. But while the methane ice quickly sublimates away, the heavier hydrocarbons created from this evaporative process remain on the surface.
Sunlight further irradiates those leftovers into reddish material – called tholins – that has slowly accumulated on Charon’s poles over millions of years. New Horizons’ observations of Charon’s other pole, currently in winter darkness – and seen by New Horizons only by light reflecting from Pluto, or “Pluto-shine” – confirmed that the same activity was occurring at both poles.
“This study solves one of the greatest mysteries we found on Charon, Pluto’s giant moon,” said Alan Stern, New Horizons principal investigator from the Southwest Research Institute, and a study co-author. “And it opens up the possibility that other small planets in the Kuiper Belt with moons may create similar, or even more extensive ‘atmospheric transfer’ features on their moons.”

NASA officials and representatives from the aerospace industry met with all 140 members of the General Assembly or their staffs, as well as Gov. Ralph Northam, Lt. Gov. Justin Fairfax, and cabinet members.
One of those lawmakers was newly elected Del. Kathy Convirs-Fowler. When she finished getting autographed pictures of Lindgren for her two children, she asked officials how aerospace initiatives can be advanced to students.
“As a former teacher, I’m very big on the programs we can implement,” she said, adding that a goal of hers is to increase the number of women and girls in science, technology, engineering, art and math (STEAM) public school programs.
It’s not every day you get to shake hands with an astronaut. Kjell Lindgren, who flew on the International Space Station, was a popular face in the group of NASA representatives on an annual journey to bring the agency’s message to Virginia lawmakers.
Sen. John Consgrove was so fired up to talk with Lindgren that he apologized for it.
“I’m sorry I’m ignoring everybody else, but I don’t get to speak to an astronaut every day,” he said.
Lindgren is used to the outsized attention, and welcomed it as an opportunity to talk about NASA’s contributions to Virginia.
“It’s one of my favorite parts of the job,” he said. “You can see that they’re very enthusiastic, very interested and excited.”

“As a former teacher, I’m very big on the programs we can implement,” she said, adding that a goal of hers is to increase the number of women and girls in science, technology, engineering, art and math (STEAM) public school programs.
“We want to excite the next generation,” Langley Deputy Director Clayton Turner told her. “That’s part of what we do.”
NASA Langley and Wallops have strong partnerships with private industry, including numerous technology transfer, commercialization and licensing success stories. In 2017, the two NASA centers brought a combined economic impact of $1.3 billion to Virginia and supported more than 10,000 jobs, according to an analysis by a private-sector company contracted by Langley.
“The collaboration has been really helpful,” Turner said.
Also, the state has assets that offer potential for growing the aerospace sector, including multiple universities, more than 285 aerospace firms, 66 public-use airports and a spaceport with access to orbit – one of only four in the U.S.
“By having two NASA centers here in Virginia, it also gives our students something to aim for,” Lindgren said. “The state is very fortunate and unique in that respect to have all those resources.”
AeroSpace Days, held for the past 13 years, aims to leverage those resources to recruit the next generation of explorers. That imperative drives Del. Marcia Price.
“If there’s anything I can do to help, especially in my community, to help with the outreach efforts so that they know about programs so my kids can be a part of the excellent things that are going on, let me know,” she said.
Those thoughts were echoed by Secretary of Education Atif Qarni, who offered to sponsor field trips to Langley and Wallops, speaking engagements, and support of science, technology, engineering and math (STEM)-related legislation.
“We’re here to help any way we can,” he said.
In addition to meeting lawmakers and their staffs, NASA was formally recognized on the floor of the Virginia Senate by Sen. Mamie Locke during session. Locke praised Langley’s contributions over the last 100 years and asked the group of NASA employees participating in AeroSpace Days to stand up and be recognized.
“That was a cool moment,” said Langley spokesman Michael Finneran.” It’s very satisfying to realize that we’re helping improve people’s lives through what we and our partners do. We felt like rock stars for a few minutes.”

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.

As Tropical Storm Hermine charged up the East Coast Sept. 2, 2016, Langley Air Force Base reached out to the Research Services Directorate and NASA Langley Research Center hangar manager Dale Bowser to see if NASA Langley could store a few F-22 Raptors. Even though the hangar in Hampton, Virginia, already had a large visitor — a C-130 from the Wallops Flight Facility on Virginia’s Eastern Shore — the hangar was able to carefully sandwich in more than a dozen Air Force fighters and offer them protection from the wind. NASA Langley photographer David C. Bowman captured the image using a fish-eye lens and shooting down from the hangar's catwalk some 70 feet above the building's floor.
The hangar provides 85,200 square feet (7,915 square meters) of open space and large door dimensions that allow for entry of big aircraft such as Boeing 757s and other commercial or military transport-class planes. The hangar normally is home to 13 of NASA Langley's own research aircraft, when they are not out doing atmospheric science or aeronautics research. Still, there is enough space to share with neighboring Langley Air Force Base during emergencies. The facility is rated for at least a Category 2 hurricane. Built in the early 1950s, it was designed to fit a B-36. It can also accommodate the Super Guppy, which visited NASA Langley in 2014.

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.
