“天体”
用英语怎么说？

Scientists believe the collected samples will provide valuable clues about the formation of Phobos and Deimos. One popular proposal, the giant impact hypothesis, suggests the moons formed after a massive celestial body struck Mars. Another theory suggests they are asteroids pulled in by gravitational force. By studying the rocks, researchers hope to understand how a habitable environment might develop on planets. The mission’s findings could also help shape future human voyages to Mars, providing crucial data for space agencies aiming to launch crewed expeditions in the coming decades.

科学家认为收集到的样本将为火卫一和火卫二的形成提供宝贵线索。一个广为流传的假说--大碰撞假说认为，这两颗卫星是在一个巨大的天体撞击火星后形成的。另一种理论则认为它们是被引力捕获的小行星。通过研究这些岩石，研究人员希望了解行星上如何形成宜居环境。该任务的发现还将有助于规划未来前往火星的人类航程，为计划在未来几十年内开展载人探险的航天机构提供关键数据。
