In this February 1944 publicity photo, men stand in front of turning vanes inside the Altitude Wind Tunnel (AWT) at the National Advisory Committee for Aeronautics Aircraft Engine Research Laboratory. The AWT was the only wind tunnel capable of testing full-size aircraft engines in simulated altitude conditions. A large wooden drive fan, located on the other side of these vanes, created wind speeds up to 500 miles per hour.

The instrument enclosure of NASA's Near-Earth Object Surveyor is prepared for critical environmental tests inside the historic Chamber A at the Space Environment Simulation Laboratory at NASA's Johnson Space Center in Houston in December 2024.

Astronauts John Young and Gus Grissom are suited for the first flight of the Gemini program in March 1965. NASA loaned Norman Rockwell a Gemini spacesuit in order to make this painting as accurate as possible.

This plaque commemorating the STS-107 space shuttle Columbia crew looks over the Mars landscape after the Mars Exploration Rover, Spirit, landed and deployed onto the red planet on Jan. 4, 2004. The plaque, mounted on the high-gain antenna, is shown while the rover underwent final checkout March 28, 2003, in the Payload Hazardous Servicing Facility at NASA's Kennedy Space Center in Florida.

Shimmering ejections emitted by two actively forming stars make up Lynds 483 (L483). High-resolution near-infrared light captured by NASA’s James Webb Space Telescope shows incredible new detail and structure within these lobes, including asymmetrical lines that appear to run into one another. L483 is 650 light-years away in the constellation Serpens.

This NASA/ESA Hubble Space Telescope Picture of the Week features a sparkling spiral galaxy paired with a prominent star, both in the constellation Virgo. While the galaxy and the star appear to be close to one another, even overlapping, they’re actually a great distance apart.

NASA astronaut Butch Wilmore, left, Roscosmos cosmonaut Aleksandr Gorbunov, second from left, and NASA astronauts Nick Hague, second from right, and Suni Williams, right are seen inside a SpaceX Dragon spacecraft aboard the SpaceX recovery ship MEGAN shortly after having landed in the water off the coast of Tallahassee, Florida, Tuesday, March 18, 2025. Hague, Gorbunov, Williams, and Wilmore are returning from a long-duration science expedition aboard the International Space Station.

NASA's SpaceX Crew-9 members pose together for a portrait inside the vestibule between the International Space Station and the SpaceX Dragon crew spacecraft.

A SpaceX Falcon 9 rocket carrying the company's Dragon spacecraft is launched on NASA’s SpaceX Crew-10 mission to the International Space Station with NASA astronauts Anne McClain and Nichole Ayers, JAXA (Japan Aerospace Exploration Agency) astronaut Takuya Onishi, and Roscosmos cosmonaut Kirill Peskov onboard, Friday, March 14, 2025, from NASA's Kennedy Space Center in Florida. NASA’s SpaceX Crew-10 mission is the tenth crew rotation mission of the SpaceX Dragon spacecraft and Falcon 9 rocket to the International Space Station as part of the agency’s Commercial Crew Program. McClain, Ayers, Onishi, and Peskov launched at 7:03 p.m. EDT from Launch Complex 39A at NASA Kennedy to begin a six-month mission aboard the orbital outpost.
