[图] 火星最高峰“奥林帕斯”山顶发现冰冻水源

This stunning image of Olympus Mons, the tallest volcano not only on #Mars but in the entire Solar System, was taken by ESA’s Mars Express as part of new research revealing water frost for the first time near Mars’s equator (where it was thought improbable for frost to exist).

Olympus Mons 奥林帕斯火山 也是全太阳系最高峰（26 km 高）。发现冻水。

这山峰又高，又有水源，地理上来说易守难攻，居高临下，又处在赤道附近，天选的火星定居点首都啊。。。
