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 second). It also committed the spacecraft to a Dec. 11 splashdown, which will air live on NASA Television, our website, and the NASA app. Follow Orion’s journey by visiting the Artemis I blog.

12月的天空会发生什么?你的夜晚行星的亮点,包括火星的消失和天马座。
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。
On Nov. 20, the fifth day of the 25.5-day Artemis I mission, a camera mounted on the tip of one of Orion’s solar array wings captured this footage of the spacecraft and the Moon as it continued to grow nearer to our lunar neighbor. The spacecraft entered the lunar sphere of influence at 2:09 p.m. EST, making the Moon, instead of Earth, the main gravitational force acting on the spacecraft. Orion completed its first flyby on the morning of Nov. 21, 2022. Follow Orion’s journey by visiting the Artemis I blog.

This composite made from ten images shows the progression of the Moon during a total lunar eclipse above the Vehicle Assembly Building, Nov. 8, 2022, at NASA’s Kennedy Space Center in Florida. Visible trailing the Moon in this composite is Mars. For North America, the partial eclipse began at 4:09 a.m. EST, with totality beginning at 5:16 a.m. One feature of a total lunar eclipse is the Moon’s red hue during totality. The red color occurs because of the refraction, filtering, and scattering of light by Earth’s atmosphere.

On Oct. 13, 2022, NASA’s Lucy spacecraft captured this image of the Earth and the Moon from 890,000 miles (1.4 million km) away. The image was taken as part of an instrument calibration sequence as the spacecraft approached Earth for its first of three Earth gravity assists. These Earth flybys provide Lucy with the speed required to reach the Trojan asteroids — small bodies that orbit the Sun at the same distance as Jupiter. On its 12-year journey, Lucy will fly by a record-breaking number of asteroids and survey their diversity, looking for clues to better understand the formation of the solar system. The image was taken with Lucy’s Terminal Tracking Camera (T2CAM) system, a pair of identical cameras that are responsible for tracking the…
