A SpaceX Falcon 9 rocket with the Surface Water and Ocean Topography (SWOT) spacecraft onboard is seen as it rolls out to the pad, Tuesday, Dec. 13, 2022, at Space Launch Complex 4E at Vandenberg Space Force Base in California. Jointly developed by NASA and Centre National D’Etudes Spatiales, with contributions from the Canadian Space Agency and the Un...
In this photo from Dec. 15, 1965, the Gemini-VII spacecraft is seen from the Gemini-VI-A spacecraft during their rendezvous mission in space. The two spacecraft are approximately 43 feet apart. Astronauts Jim Lovell and Frank Borman launched on Gemini-VII on Dec. 4, 1965, and eventually spent two weeks in orbit, the longest-duration flight at that time. Just...
At 12:40 p.m. EST, Dec. 11, 2022, the Orion spacecraft for the Artemis I mission splashed down in the Pacific Ocean after a 25.5-day mission to the Moon. Flight controllers in mission control at NASA’s Johnson Space Center in Houston spent about two hours performing tests in open water to gather additional data about the spacecraft. Orion was then recovered ...
On flight day 20 of the Artemis I mission, Dec. 5, 2022, Orion captured the Moon on the day of return powered flyby, the final major engine maneuver of the flight test. The burn, which used the spacecraft’s main engine on the European-built service module, lasted 3 minutes, 27 seconds, and changed the velocity of the spacecraft by about 655 mph (961 feet per...
In this illustration by Rick Giudice from August 1973, the Pioneer 10 spacecraft passes by the gas giant planet Jupiter. The spacecraft’s primary goal was to explore Jupiter, its satellites, its magnetic field, and trapped radiation belts. Pioneer 10 was the first satellite to pass through an asteroid belt and the first spacecraft to obtain detailed im...
这张经典的地球照片拍摄于1972年12月7日，由最后一次阿波罗任务阿波罗17号的宇航员拍摄，当时他们正在执行登月任务，前往月球。阿波罗的轨道第一次使拍摄南极冰盖成为可能，如图所示的是南半球厚厚的云层。
1993年12月，航天飞机任务STS-61的机载视图显示宇航员斯托里·马斯格雷夫和杰弗里·霍夫曼为修理哈勃太空望远镜而进行的机外活动（EVA）。STS-61是哈勃太空望远镜的首次服务任务。
On the 19th day of the Artemis I mission, Dec. 4, 2022, a camera mounted on the Orion spacecraft captured the Moon just in frame as Orion prepared for its return powered flyby on Dec. 5, when it passed approximately 79 miles above the lunar surface. Orion performed the return powered flyby burn at 11:43 a.m. EST, changing the velocity of the spacecraft by ap...
Against a backdrop littered with tiny pinpricks of light glint a few, brighter stars. This whole collection is NGC 1858, an open star cluster in the northwest region of the Large Magellanic Cloud, a satellite galaxy of our Milky Way that boasts an abundance of star-forming regions. NGC 1858 is estimated to be around 10 million years old. Open clusters are a ...
2022年11月21日，在阿尔忒弥斯1号任务的第六天，猎户座飞船的光学导航相机拍摄到了月球下方陨石坑的黑白图像。这张照片和其他拍摄到的照片是自阿波罗号以来从载人飞船上拍摄的离月球最近的照片。光学导航相机以不同的相位和距离拍摄地球和月球的黑白图像；这项技术演示将有助于证明其在未来载人任务中的有效性。
