NASA spacecraft succeeds in sampling the asteroid Bennu
小惑星ベンヌを周回している米航空宇宙局（ＮＡＳＡ）の探査機「オリシス・レックス」が米東部時間の２０日午後（日本時間２１日朝）、ロボットアームで小惑星「ベンヌ」の地表に接触し、サンプルを採取しました
NASA’s spacecraft ”Olisis Rex” orbiting the asteroid Bennu touches the surface of the asteroid ”Bennu” with a robot arm on the afternoon of the 20th (21st morning Japan time) EST.
The NASA team announced that the work was completed successfully based on the data from the spacecraft.
Bennu is an asteroid shaped like a top made up of a collection of rocks.
In the 22nd century, it is said that there is a risk of approaching the earth and colliding with a probability of 1/2700.
The spacecraft was launched in September 2016 and entered the orbit of Benne in December 2018.
Based on the observation data from the orbit, a sampling point called ”Nightingale” was selected.
It descends from an orbit of about 760 meters above Benne over 4 hours, injects nitrogen gas and winds up the surface material, and collects it with a filter attached to a robot arm about 3 meters in length.
