NASA’s Perseverance Mars rover landed on the Red Planet on Feb. 18, 2021, and took this selfie over a rock nicknamed “Rochette,” on Sept. 10, 2021, the 198th Martian day, or sol of the mission. Two holes can be seen where the rover used its robotic arm to drill rock core samples. See the other selfies Perseverance took on that day! Perseverance uses a camera...
A top view shows the wing loading test configuration of a F/A-18E from the Naval Air Systems Command (NAVAIR) in Patuxent River, Maryland. While the aircraft was in NASA’s Armstrong Flight Research Center Flight Loads Laboratory in Edwards, California, it underwent the center’s biggest load calibrations tests. That testing was needed before the aircraft coul...
This artist’s concept from 2015 shows exoplanet Kepler-1649c orbiting around its host red dwarf star. This exoplanet is in its star’s habitable zone (the distance where liquid water could exist on the planet’s surface) and is the closest to Earth in size and temperature found to that date in data from the Kepler mission. The Kepler mission ...
As NASA prepares to send astronauts to the Moon through the Artemis Program, engineers are working on technologies that will give these explorers power – solar power, that is. In space, the harsh radiation and huge temperature changes make for a challenging environment. Dr. Lyndsey McMillon-Brown at NASA’s Glenn Research Center leads a study of solar cells m...
This image from the NASA/ESA Hubble Space Telescope feels incredibly three-dimensional for a piece of deep-space imagery. The image shows Arp 282, an interacting galaxy pair composed of the Seyfert galaxy NGC 169 (bottom) and the galaxy IC 1559 (top). Interestingly, both galaxies have monumentally energetic cores known as active galactic nuclei (AGN), althou...
This view of Jupiter was taken by Voyager 1. This image was taken through color filters, recombined to produce the color image, and assembled from three black and white negatives by the Image Processing Lab at Jet Propulsion Laboratory. The twin Voyager 1 and 2 spacecraft are exploring where nothing from Earth has flown before. Continuing on their more-than-...
NASA astronaut Mark Vande Hei peers at the Earth below from inside the seven-windowed cupola, the International Space Station’s window to the world. Just outside the cupola is the Soyuz MS-19 crew ship docked to the Rassvet module. Vande Hei is slated to become the U.S. record holder for most time spent in space. He arrived on station on April 9, 2021,...
In this image from February 1966, mathematician Daniel G. Nichols, who worked in the Real-Time Program Development Branch, Mission Planning and Analysis Division, is photographed at NASA’s Manned Space Center (now the Johnson Space Center) in Houston. Nichols worked for the agency more than 25 years, including in mission control during the Apollo Program. Ac...
This image from January 2022 shows the first rays of an orbital sunrise as seen from the International Space Station as it orbited 257 miles above the coast of Venezuela. As the station orbits the Earth, completing one trip around the globe every 92 minutes, the astronauts experience 15 or 16 sunrises and sunsets every day. 这张2022年1月的照片显示了国际空间站在委内瑞拉海岸上空257英里...
As NASA prepares to send astronauts to the Moon’s South Pole under Artemis, divers at the Neutral Buoyancy Laboratory (NBL) in Houston are setting the stage for future moonwalk training by simulating lunar lighting conditions. At the Moon’s South Pole, the Sun will remain no more than a few degrees above the horizon, resulting in extremely long and dark shad...
