这张照片拍摄于上周日，9月24日，盐湖城附近的国防部犹他测试和训练靶场。从小行星101955 Bennu返回后，一个110磅重、31英寸宽的样本回返舱躺在地球上的沙漠里。由奥西里斯-雷克斯宇宙飞船降落的太空舱，由于在地球稠密的大气层中剧烈下降时经历的极端温度，看起来已经烧焦了。OSIRIS-Rex于2021年5月开始从Bennu返回家园的旅程。9月25日，“贝努”号太空舱将被送往休斯顿的美国宇航局约翰逊航天中心，预计太空舱的容器内将装有大约半磅（250克）未受污染的样本，这些样本是松散包装的“贝努”号风化层。科学家和工程师将在为OSIRIS-REx任务设计的新实验室工作，完成气罐拆卸过程，并计划在10月11日的广播活动中公布这颗近地小行星的样本。

Back from asteroid 101955 Bennu, a 110-pound, 31-inch wide sample return capsule rests in a desert on planet Earth in this photo, taken at the Department of Defense Utah Test and Training Range near Salt Lake City last Sunday, September 24. Dropped off by the OSIRIS-Rex spacecraft, the capsule looks charred from the extreme temperatures experienced during its blistering descent through Earth's dense atmosphere. OSIRIS-Rex began its home-ward journey from Bennu in May of 2021. Delivered to NASA’s Johnson Space Center in Houston on September 25, the capsule's canister is expected to contain an uncontaminated sample of about a half pound (250 grams) of Bennu's loosely packed regolith. Working in a new laboratory designed for the OSIRIS-REx mission, scientists and engineers will complete the canister disassembly process, and plan to unveil the sample of the near-Earth asteroid in a broadcast event on October 11.
