返回地球前,猎户座凝视着月亮

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...

先锋10号飞越木星

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...

奋进号机组人员对哈勃进行维修

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。

猎户座在返回飞越前接近月亮

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...

哈勃望远镜发现发射星云双星团

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 ...

猎户座的月球环形山特写

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。

猎户座、地球和月球

2022年11月28日,周一,NASA的猎户座宇宙飞船在执行阿尔忒弥斯1号任务时达到了它与地球的最大距离——距离我们的母星268,563英里,比以往任何旨在将人类送往太空和返回的宇宙飞船都要远。在这张照片中,猎户座号捕捉到了地球和月球的独特视角,这是由安装在飞船太阳能电池阵列上的相机拍摄。

猎户座接近月球,进行返回动力飞掠

A portion of the far side of the Moon looms large just beyond the Orion spacecraft in this image taken Monday, Nov. 21, the sixth day of the Artemis I mission, by a camera on the tip of one of Orion’s solar arrays.
