    I’m not so sure… At those speeds, it would’ve taken under 10 seconds to completely clear the atmosphere. Even with intense compressional heating, I don’t think it would’ve been in contact with the atmosphere long enough to completely vaporize — although it probably didn’t look much like a manhole cover anymore by the time it escaped.




  • Arsia Mons! One of Mars’ largest volcanos, and part of an arc of three known collectively as the Tharsis Montes. The volcano to the top right is Pavonis Mons, and further beyond (past the visible horizon) is Ascraeus Mons. The much more famous Olympus Mons is also found in the same region, to the northeast of the Tharsis Montes (which would be towards the bottom right in this particular image).

    Interestingly, that massive cloud formation is a yearly phenomenon that happens right before the start of winter. The size of the cloud trail varies from year to year, but it’s not uncommon for it to stretch more than 1000 kilometers.
