为毅力号火星漫游车在火星上收集样本做准备

The samples Apollo 11 brought back to Earth from the Moon were humanity’s first from another celestial body. NASA’s upcoming Mars 2020 Perseverance rover mission will collect the first samples from another planet (the red one) for return to Earth by subsequent missions. In place of astronauts, the Perseverance rover will rely on the most complex, capable and cleanest mechanism ever to be sent into space, the Sample Caching System.

In this image taken on May 20, 2020 at the Kennedy Space Center, engineers and technicians insert 39 sample tubes into the belly of the rover. Each tube is sheathed in a gold-colored cylindrical enclosure to protect it from contamination. Perseverance rover will carry 43 sample tubes to the Red Planet’s Jezero Crater.

阿波罗11号从月球带回的样品是人类从另一个天体带回的第一批样品。NASA即将发射的火星2020毅力号漫游车将从另一颗行星(红色的那颗)采集首批样本，并在随后的任务中返回地球。毅力号漫游车将依靠有史以来最复杂、最有能力、最干净的太空采样系统来取代宇航员。

在这张于2020年5月20日在肯尼迪航天中心拍摄的照片中，工程师和技术人员将39个采样管插入漫游车的腹部。每根管子都被套在一个金色的圆柱形外壳中，以保护它不受污染。毅力号漫游车将携带43个样品管到红色星球的杰泽罗火山口。
