NASA snags sample of asteroid

美探测器从小行星采样

NASA said its OSIRIS-REx mission touched down on asteroid Bennu on Tuesday and collected a sample from the asteroid's surface. It is the first US mission to retrieve a pristine sample of an asteroid and return it to Earth for further study.

美国宇航局宣布,“奥西里斯-雷克斯”探测器10月20日降落到小行星“本努”表面并完成了岩石样本采集任务,这是美国首次在小行星表面采集到原始的岩石样本,并运回地球作进一步研究。

The spacecraft performed the entire sequence of approaching the asteroid and collecting the sample autonomously, which lasted about 4.5 hours. The sample is scheduled to be returned to Earth in September 2023.

探测器接近小行星并自动采集样本的整个过程持续了大约4.5小时,预计在2023年9月能将样本送返地球。

OSIRIS-REx was launched on Sept 8, 2016 and arrived at Bennu on Dec 3, 2018.

“奥西里斯-雷克斯”探测器于2016年9月8日发射,并于2018年12月3日抵达小行星“本努”附近。

The samples from Bennu could help scientists understand not only more about asteroids that could impact Earth but also about how planets formed and life began.

来自“本努”的岩石样本不仅可以帮助科学家更多地了解可能撞击地球的小行星,还可以帮助他们了解行星的形成和生命的起源。
