介绍Quesst：速度从未如此安静

ByNASA中文 2022年5月17日2022年5月17日

Evoking the experimental nature of flight testing and the spirit of aeronautical exploration, Quesst is what NASA is calling its mission to enable supersonic air travel over land. This new moniker – complete with an extra “s” to represent “supersonic” – draws its inspiration from NASA’s long legacy of supersonic flight research. Quesst, which replaces the mission’s original name: the Low-Boom Flight Demonstration, effectively conveys the purpose and excitement of a journey that could lead to a dramatic reduction in passenger air travel time. With the introduction of Quesst comes a new mission identity — a blue and green signature mark that represents the elements of Quesst. The mission graphic displays stylized supersonic shockwaves encircling the research aircraft, above a community of homes. The imagery…

哈勃在巨蛇座的头部拍摄到了巨大的椭圆

ByNASA中文 2022年5月14日2022年5月14日

This new NASA Hubble Space Telescope image spotlights the giant elliptical galaxy, UGC 10143, at the heart of galaxy cluster, Abell 2147, about 486 million light-years away in the head of the serpent, the constellation Serpens. UGC 10143 is the biggest and brightest member of Abell 2147, which itself may be part of the much larger Hercules Supercluster of galaxies. UGC 10143’s bright center, dim extended halo, and lack of spiral arms and star-forming dust lanes distinguish it as an elliptical galaxy. Ellipticals are often near the center of galaxy clusters, suggesting they may form when galaxies merge. This image of UGC 10143 is part of a Hubble survey of globular star clusters associated with the brightest galaxies in galaxy clusters. Globular star clusters help…

轨道上的地球：NOAA首次发布GOES-18卫星图像

ByNASA中文 2022年5月13日2022年5月13日

On May 11, 2022, the National Oceanic and Atmospheric Administration, or NOAA, shared the first images of the Western Hemisphere from its Geostationary Operational Environmental Satellite-T (GOES-T). Later designated GOES-18, the satellite’s Advanced Baseline Imager (ABI) instrument recently captured stunning views of Earth. Launched by NASA on March 1, GOES-18 lifted off at 4:38 p.m. EST from Cape Canaveral Space Force Station’s Space Launch Complex 41 in Florida. The ABI views Earth with 16 different channels, each measuring energy at different wavelengths along the electromagnetic spectrum to obtain information about Earth’s atmosphere, land, and ocean.

从空间站看地球

ByNASA中文 2022年5月10日2022年5月10日

NASA astronaut Jessica Watkins floats in the International Space Station’s cupola, a direct nadir viewing window from which Earth and celestial objects are visible. Watkins reported for duty in August 2017 and completed two years of training as an astronaut candidate. Her astronaut candidate training included scientific and technical briefings, intensive instruction in space station’s systems, spacewalks, robotics, physiological training, T-38 flight training, water and wilderness survival training, geology training, and expeditionary skills training. Watkins also served as an aquanaut crew member in the Aquarius underwater habitat for the NASA Extreme Environment Mission Operations, or NEEMO, 23 mission in 2019. Watkins is currently serving as a mission specialist on NASA’s SpaceX Crew-4 mission to the space station, which launched on April 27, 2022. Image Credit:…

NASA的SpaceX Crew-3溅落

ByNASA中文 2022年5月7日2022年5月7日

The SpaceX Crew Dragon Endurance spacecraft is seen shortly after it landed with NASA astronauts Raja Chari, Kayla Barron, Tom Marshburn, and European Space Agency astronaut Matthias Maurer aboard. The craft splashed down in the Gulf of Mexico, off the coast of Tampa, Florida, Friday, May 6, 2022. Maurer, Marshburn, Chari, and Barron are returning after 177 days in space after completing the agency’s third long-duration commercial crew mission as part of Expeditions 66 and 67 aboard the International Space Station. Image Credit: NASA/Aubrey Gemignani SpaceX的Endurance号载人龙飞船与NASA宇航员拉贾·查里、凯拉·巴伦、汤姆·马什本和欧洲航天局宇航员马蒂亚斯·毛雷尔一起溅落后不久就被找到。这艘飞船于2022年5月6日星期五溅落在佛罗里达州坦帕海岸附近的墨西哥湾。毛雷尔、马什本、查理和巴伦在太空中飞行了177天，完成国际空间站第66号和第67号远征队的第三次长期商业载人任务。影像来源：NASA/Aubrey Gemignani

黑洞很难被发现

ByNASA中文 2022年5月5日2022年5月5日

Black holes are hard to find. They have such strong gravity that light can’t escape them, so scientists must rely on clues from their surroundings to find them. When a star weighing more than 20 times the Sun runs out of fuel, it collapses into a black hole. Scientists estimate that there are tens of millions of these black holes dotted around the Milky Way, but so far we’ve only identified a few dozen. This image from 2001 is an artist’s impression of a black hole accretion disk. Around many black holes is an accretion disk of material emitting energy as it falls into the black hole. Learn more about black holes.
