使用兰利的14乘22英尺亚音速风洞进行50年的研究

Dec. 11, 2020, marks the 50th anniversary of NASA’s Langley Research Center’s 14×22 Subsonic Wind Tunnel. The facility is used to assess aerodynamic performance of aircraft over a wide range of takeoff, landing, cruise, and high angle-of-attack conditions. It can provide acoustic, tethered free-flight, and forced-oscillation testing, motorsports researc...

3D打印火箭部件和宇宙飞船的未来

Future lunar landers might come equipped with 3D printed rocket engine parts that help bring down overall manufacturing costs and reduce production time. NASA is investing in advanced manufacturing – one of five industries of the future – to make it possible. Through a series of hot-fire tests in November, NASA demonstrated that two additively manufactured e...

NASA和波音公司完成了一系列星际客机的降落伞测试

NASA and Boeing have completed Starliner’s last parachute balloon-drop test designed to strengthen the spacecraft’s landing system ahead of crewed flights to and from the International Space Station. Read the full story. The tests, developed by Boeing and NASA, used six balloon-drop tests of a Starliner test article to gather supplemental performance data on...

哈勃望远镜凝视着宇宙仙境

This large expanse of space captured with the Hubble Space Telescope features the galaxy SDSS J225506.80+005839.9. Unlike many other extravagant galaxies and stunning nebulae imaged by Hubble, this galaxy does not have a short, popular name, and is only known by its long name given in the Sloan Digital Sky Survey, which refers to its coordinates in the sky. ...

在国际空间站的世界之窗内放松

JAXA (Japan Aerospace Exploration Agency) and Expedition 64 astronaut Soichi Noguchi relaxes at the end of the work day inside the seven-windowed cupola, the International Space Station’s “window to the world.” The orbiting lab was flying above the South Pacific at the time this photograph was taken on Nov. 27, 2020. December will be a busy...

觉醒的新生恒星

Lying inside our home galaxy, the Milky Way, this Herbig–Haro object is a turbulent birthing ground for new stars in a region known as the Orion B molecular cloud complex, located 1,350 light-years away. Herbig–Haro (HH) objects are bright patches of nebulosity associated with newborn stars that form when narrow jets of partially ionized gas ejected by stars...

地球可能被毛状暗物质包围着

The solar system might be a lot hairier than we thought. This illustration shows Earth surrounded by theoretical filaments of dark matter called “hairs.” Dark matter is an invisible, mysterious substance that makes up about 27 percent of all matter and energy in the universe. The regular matter, which makes up everything we can see around us, is ...
