美探測器從小行星採樣

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.
美國宇航局宣佈，“奧西里斯-雷克斯”探測器10月20日降落到小行星“本努”表面並完成了岩石樣本採集任務，這是美國首次在小行星表面採集到原始的岩石樣本，並運回地球作進一步研究。

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.
探測器接近小行星並自動採集樣本的整個過程持續了大約4.5小時，預計在2023年9月能將樣本送返地球。

OSIRIS-REx was launched on Sept 8, 2016 and arrived at Bennu on Dec 3, 2018.
“奧西里斯-雷克斯”探測器於2016年9月8日發射，並於2018年12月3日抵達小行星“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.
來自“本努”的岩石樣本不僅可以幫助科學家更多地瞭解可能撞擊地球的小行星，還可以幫助他們瞭解行星的形成和生命的起源。
