The Sun’s rays begin to illuminate the Earth’s atmosphere as the International Space Station flew into an orbital sunrise 261 miles above Texas, as seen in this image taken by astronaut Bob Hines. The crew doesn’t just snap pretty pictures; the research aboard the station benefits humanity in numerous ways. This week, the 11th annual Intern...
Before NASA’s quiet supersonic X-59 aircraft takes to the skies, plenty of testing happens to ensure a safe first flight. One part of this safety check is to analyze data collected for the X-59’s flight control system through low-speed wind tunnel tests. The X-59 is central to NASA’s Quesst mission to expand supersonic flight and provide regulators with data...
Though Mars is the Red Planet, false-color images can help us learn about its weather and geology. This image shows a variety of wind-related features on the Red Planet near the center of Gamboa Crater. Larger sand dunes form sinuous crests and individual domes. There are tiny ripples on the tops of the dunes, only several feet from crest-to-crest. These mer...
An Alta-X drone operated by NASA researchers flies over NASA Langley’s City Environment Range Testing for Autonomous Integrated Navigation (CERTAIN) as part of the Advanced Air Mobility project’s High Density Vertiplex (HDV) testing in April 2022. HDV is developing the necessary systems to enable urban drone flights that travel beyond visual sight. Lea...
The Apollo 11 crew simulates deploying and using lunar tools on the surface of the Moon during a training exercise on April 22, 1969. Lunar module pilot Buzz Aldrin (left) uses a scoop and tongs to pick up a soil sample. Mission Commander Neil Armstrong holds a bag to receive the sample. In the background is a Lunar Module mockup. On July 16, 1969, the crew ...
Supernovas are the explosive deaths of the universe’s most massive stars. In death, these objects blast powerful waves into the cosmos, destroying much of the dust surrounding them. This 2007 composite from NASA’s Spitzer Space Telescope and Chandra X-ray Observatory shows the remnant of such an explosion, known as N132D, and the environment it i...
This tunnel view looking up from Level 5 is of the Zero Gravity Facility at Lewis Research Center, now known as John H. Glenn Research Center at Lewis Field, and was taken in Cleveland, Ohio, on Sept. 12, 1966. The tower dropped 460 feet and allowed scientists to perform 5.18 seconds of microgravity research. By comparison, the Washington Monument is 555 fee...
A SpaceX Falcon 9 rocket carrying the Dragon capsule soars upward after lifting off from Launch Complex 39A at NASA’s Kennedy Space Center in Florida on July 14, 2022, on the company’s 25th Commercial Resupply Services mission to the International Space Station. Liftoff was at 8:44 p.m. EDT. Dragon will deliver more than 5,800 pounds of cargo, including a va...
Senior Project Scientist John Mather, winner of the 2006 Nobel Prize for Physics, speaks with members of the media following the release of the first full-color images from NASA’s James Webb Space Telescope, Tuesday, July 12, 2022, at Goddard Space Flight Center in Greenbelt, Md. The first full-color images and spectroscopic data from the telescope, a partne...
President Joe Biden previews the first full-color image from NASA’s James Webb Space Telescope, the highest-resolution image of the infrared universe in history, Monday, July 11, 2022, in Washington. On screen are NASA Associate Administrator for the Science Mission Directorate Thomas Zurbuchen, top, Deputy Director of the Space Telescope Science Institute (...
