- ChuckMcM 15y agoI am glad that one of the current rovers wasn't in a position to have water wash over them. Especially salty water which is very conductive. That would be like 'instant death' for a robot probe. Of course all of these things could have been discovered and analyzed much more quickly and definitively with a person present ...
- gus_massa 15y agoThe Mars' circumference is ~13000 miles / ~21000 Km. If the landing site is on the correct side of Mars, the astronauts have to travel, let's say 2000 miles / 3000 Km, without roads or gas stations. So probably in the fists expeditions the persons will explore only the neighborhoods of the landing site, and will not be able to travel to the interesting sites.
- mturmon 15y agoThe analysis in the OP was from an orbiter, not a lander. The chances of landing a crew near such a site by chance seem low. And it would not happen this decade anyway. You need unmanned surveys to determine if and where it would be worthwhile to send a crew.
