2021年9月11日 Saturn at Night Image Credit: NASA, JPL-Caltech, Space Science Institute, Mindaugas Macijauskas Explanation: Still bright in planet Earth’s night skies, good telescopic views of Saturn and its beautiful rings often make it a star at star parties. But this stunning view of Saturn’s rings and night side just isn’t possible from tel...
The pressure vessel is the primary structure for Orion’s crew module, joined together using state-of-the-art welding by technicians from lead contractor Lockheed Martin. Both the Orion spacecraft and the Space Launch System (SLS) rocket are making progress towards Artemis missions to the Moon. With the spacecraft for the Artemis I and II missions manufacture...
2021年9月10日 Rosetta’s Comet in View Image Credit & Copyright: Rolando Ligustri (CARA Project, CAST) Explanation: Faint comet Churyumov-Gerasimenko (67P) sweeps past background stars in the constellation Taurus and even fainter distant galaxies in this telescopic frame from September 7. About 5 years ago, this comet’s 4 kilometer spanning, dou...
Mary W. Jackson grew up in Hampton, Virginia and attended the historically black college Hampton Institute (now Hampton University), earning bachelor of science degrees in mathematics and physical science. Each year, we celebrate National Historically Black Colleges and Universities (HBCUs) Week under the leadership of the White House Initiative on HBCUs and...
在成功完成最后的测试后，可以看到NASA的詹姆斯·韦伯太空望远镜正准备运往发射场。 图片来源：NASA/Chris Gunn NASA计划于2021年12月18日将詹姆斯·韦伯太空望远镜送入轨道，作为未来十年的主要深空观测站。 在韦伯望远镜最近成功完成其严格的测试方案之后，NASA与阿丽亚娜航天公司协调确定了新的发射日期——这是该任务的一个重要转折点。在此之前，阿丽亚娜空间公司于7月下旬成功发射了阿丽亚娜5号火箭，并计划在韦伯望远镜之前发射。今年7月的发射是阿丽亚娜5号自2020年8月以来的首次发射。 韦伯望远镜是NASA与欧空局（European Space Agency）和加拿大航天局合作的国际项目，将由阿丽亚娜5号火箭从南美洲东北部海岸的法属圭亚那的欧洲太空港发射。欧空局提供阿丽亚娜5号。 这个高度复杂的...
Apurva Varia joined the Goddard Space Flight Center in 2002 as a propulsion engineer. For 13 years, he analyzed, designed, and tested the propulsion systems for spacecraft, including the Solar Dynamics Observatory, Magnetospheric Multiscale, and Deep Space Climate Observatory. He was the first deaf engineer to monitor and analyze the telemetry from a propuls...
Instrumentation technician Michael Hodgins performs installation measures on the trans-sonic truss-braced wing (TTBW) model at Langley Research Center’s 14×22 subsonic wind tunnel. The unique design of the aircraft’s wings reduces drag during flight, which in turn reduces fuel consumption by up to 10 percent. This concept is part of an ongoing initiativ...
2021年9月9日 M16 Cose Up Image Credit & Copyright: Martin Pugh Explanation: A star cluster around 2 million years young surrounded by natal clouds of dust and glowing gas, M16 is also known as The Eagle Nebula. This beautifully detailed image of the region adopts the colorful Hubble palette and includes cosmic sculptures made famous in Hubble Space Telesco...
2021年9月8日 The Deep Sky Toward Andromeda Image Credit & License: Stefan Ziegenbalg Explanation: What surrounds the Andromeda galaxy? Out in space, Andromeda (M31) is closely surrounded by several small satellite galaxies, and further out it is part of the Local Group of Galaxies — of which our Milky Way galaxy is also a member. On the sky, however,...
这个密封的钛合金样品管里有毅力号的第一个火星岩石岩芯样本。火星车的取样和缓存系统相机（称为CacheCam）拍摄到了这一图像。 影像来源：NASA/JPL-Caltech NASA的毅力号火星车今天完成了第一个火星岩石样本的采集，这是一个来自杰泽罗陨石坑的岩芯，比铅笔略粗。位于南加州的NASA喷气推进实验室（JPL）的任务控制人员收到的数据证实了这一历史性里程碑。 该岩芯现在被封在一个密闭的钛合金样品管中，使其在未来可以被回收。通过火星样本返回活动，NASA和ESA（欧洲航天局）正在计划一系列未来的任务，将火星车的样品管送回地球进行更深入的研究。这些样品将是第一组经过科学鉴定和挑选的从另一个星球返回地球的材料。 在这张由毅力号的采样和缓存系统相机（CacheCam）拍摄的照片中，可以看到毅力号的第一个火星岩芯样...
