干燥的火星（Mars）陨石（meteorite）揭示了火星地壳早期的水

科学家通过研究坠落至地球（Earth）的火星陨石，探索这颗红色行星的古代环境。这些陨石为研究火星早期地壳中的水提供了宝贵的样本，弥补了目前缺乏直接采样任务的遗憾。

Billions of years ago, Mars was hypothesized to have been a habitable world with flowing liquid water and the potential for life. But directly studying its ancient past is currently limited to orbiters and rovers, as scientists have yet to obtain direct samples from Mars. However, meteorites have been found on Earth to have potentially originated from Mars during large impacts that flung chunks of the Red Planet into space, eventually being grabbed by Earth’s gravity and crashing into the Earth’s surface.
