来自欧洲和美国的研究人员和宇宙飞船工程师正在进行一项使小行星“转向”的任务,并“证明这项技术是一种可行的行星防御方法”。
This mission is called the Asteroid Impact Deflection Assessment (AIDA) and will attempt to redirect the smaller part of a pre-selected double asteroid called Didymos.
这项任务被称为小行星撞击偏转评估(AIDA),它将试图使预先选定的双小行星系统Didymos中的小卫星转向。
In the first stage of the mission, a spacecraft will deliberately crash into the space rock.
在任务的第一阶段,一艘宇宙飞船将故意撞向这颗小行星。
Then a second ship will assess the crash site and gather data on the effects of the collision.
之后第二艘宇宙飞船将评估撞击地点,收集有关撞击影响的数据。
NASA is already working on a craft called Double Asteroid Impact Test, whilst Italy will send a mini satellite to gather data as the mission progresses.
美国国家航空航天局已经在研究一种名为“双小行星撞击测试”的航天器,而在这项任务实施过程中,意大利将发射一颗迷你卫星来收集数据。
The European Space Agency [ESA] mission, called Hera, will perform “a close-up survey of the post-impact asteroid,” collecting vital information about such as the asteroid’s composition as well as the size of the crater left behind after impact.
