How to get there and how high you can go before needing oxygen.
No one as landed on Mars, walked on Mars, or lived on Mars. For rubbish cans or trash cans to exist on Mars, humans would need to be on Mars and either bring the rubbish cans or manufacture these on the planet. None of that is possible in the conceivable future, because Mars' atmosphere cannot support human life. Even if we assume ANY other life lived there before, we cannot assume their method of trash collection or removal.
Familiarity with orbital mechanics would be an excellent idea. That, and some really big engines. Our unmanned missions to Mars have all been launched on the civilian equivalent of Intercontinental Ballistic Missiles.
Today's current cell phones will not work on Mars. And we would need a way to get to Mars first.

Does he really need to know this? You can just say you didn't know they were enemies and it was before you met him. There is nothing else you can do.
Hah! No, we know all we need to know about her!
After astronauts arrive at Mars they will need to wait 15.4 months for the Earth and Mars to line up right before they launch In order to make it back home.
Probably of stalkers like you. Do you need to know what he is afraid of?
10sep 2009 I don't know what that answer means. Mars has been obvious for thousands of years. It didn't really need "discovering".
