维克多·格洛弗,SpaceX Crew-1飞行员

Astronaut Victor Glover was assigned to the first mission to the International Space Station onboard SpaceX’s Crew Dragon, during an event on Friday, Aug. 3, 2018, at NASA’s Johnson Space Center in Houston, Texas. Other astronauts assigned to crew the first flight tests and missions of the Boeing CST-100 Starliner and SpaceX Crew Dragon also were announced d...

哈勃望远镜观测到一对奇特的星系

This striking image from the NASA/ESA Hubble Space Telescope showcases Arp 298, a stunning pair of interacting galaxies. Arp 298 – which comprises the two galaxies NGC 7469 and IC 5283 – lies roughly 200 million light-years from Earth in the constellation Pegasus. The larger of the two galaxies pictured here is the barred spiral galaxy NGC 7469, and IC 5283 ...

泰德·布朗:太空时代的艺术家

“There are few artists in the aerospace industry whose career was as varied or accomplished as Ted Brown,” so reads his artist profile on the blog numbers station by Mike Acs. Brown “began as a graphic designer with [McDonnell] Douglas in 1962, and over the next four decades carved out an enviable career: he illustrated everything from the ...

研究微重力中的火焰

This image from 2020 shows a flame that was one of many ignited as part of the Flame Design investigation inside of Combustion Integrated Rack (CIR) to investigate the amount of soot that is produced in different conditions. The yellow spots are soot clusters that glow yellow when hot. These clusters grow larger in microgravity than on Earth because the soot...

梅尔巴·罗伊·穆顿——数学家

Melba Roy Mouton (1929-1990) was a mathematician and computer programmer in NASA’s Trajectory and Geodynamics Division, acting as the Assistant Chief of Research Programs. Mouton worked at NASA’s Goddard Space Flight Center, coding computer programs to calculate the trajectories and locations of various aircraft. She also led the group of “human comput...

在红色星球上自拍

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...

NASA测试F/A-18E

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...

围绕红矮星运行

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 ...

林赛·麦克米隆·布朗博士:研究太阳能电池

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...

哈勃观测到宇宙间的相互作用

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...
