NASA is taking a leading role to help integrate new types of Advanced Air Mobility aircraft like air taxis and delivery drones into the sky, helping emerging markets to safely develop an air transportation system that moves people and cargo between places previously not served or underserved by aviation. NASA is working with private sector developers of elec...
A portion of the open cluster NGC 6530 appears as a roiling wall of smoke studded with stars in this image from the NASA/ESA Hubble Space Telescope. NGC 6530 is a collection of several thousand stars lying around 4,350 light-years from Earth in the constellation Sagittarius. The cluster is set within the larger Lagoon Nebula, a gigantic interstellar cloud of...
Against an inky black backdrop, the blue swirls of spiral galaxy NGC 6956 stand out radiantly. NGC 6956 is a barred spiral galaxy, a common type of spiral galaxy with a bar-shaped structure of stars in its center. This galaxy exists 214 million light-years away in the constellation Delphinus. Scientists used NASA’s Hubble Space Telescope to image NGC 6956 to...
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。
