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 images of Jupiter and its moons. Between 1972 and 1974, the Deep Space Network ground stations tracked the Pioneer 10 for over 21,000 hours. Pioneer 10 fell silent on its 30-year anniversary in 2002.

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 approximately 655 mph (961 feet per second). The return powered flyby is the last large maneuver of the mission, with only smaller trajectory corrections to target Earth remaining. Follow Orion’s journey by visiting the Artemis I blog.

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 type of star cluster with loose gravitational attraction between the stars, which causes the cluster to be irregularly shaped and its stars to be spread out. NGC 1858 is also an emission nebula, which is a cloud of interstellar gas that has been ionized by ultraviolet wavelengths radiating off of nearby stars. The gas of the nebula emits its own light at visible…

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。
