This week in 1999, space shuttle Discovery, mission STS-103, launched from NASA’s Kennedy Space Center on the third Hubble Space Telescope servicing mission. Over the course of three planned extravehicular activities, the STS-103 crew restored Hubble to working order and upgraded some of its systems, allowing the then decade-old observatory to get ready to b...
波音公司的无人轨道飞行测试(OFT)是美国国家航空航天局商业乘务计划的第二次无人飞行测试，该计划与航空航天工业合作，自2011年以来首次在美国本土用美国火箭和宇宙飞船发射宇航员。 10月16日，波音公司的CST-100星际飞船的乘员舱在佛罗里达州肯尼迪航天中心的商业乘员和货物处理设施(C3PF)内被送上服务舱，这是该公司飞往国际空间站的轨道飞行测试的一部分，也是NASA商业乘员计划的一部分。 来源:Boeing 12月20日，当波音公司的Starliner航天飞机搭乘美国联合发射联盟的“阿特拉斯5号”火箭从佛罗里达州卡纳维拉尔角空军基地的航天发射场41号发射中心发射升空时，研究太空中物体运动规律的科学家们将成为热切的观众，屏息以待。 对于NASA的执行任务，Starliner将能够发射多达4名机组人员和大约22...
As the holiday season approaches, people in the northern hemisphere will gather indoors to stay warm. In keeping with the season, astronomers have studied two groups of galaxies that are rushing together and producing their own warmth. The majority of galaxies do not exist in isolation. Rather, they are bound to other galaxies through gravity either in relat...

2019 December 18 A Hotspot Map of Neutron Star J0030’s Surface Image Credit: NASA, NICER, GSFC’s CI Lab Explanation: What do neutron stars look like? Previously these city-sized stars were too small and too far away to resolve. Recently, however, the first maps of the locations and sizes of hotspots on a neutron star’s surface have been mad...
