it would need to have water in the first place.
You would need a rocket ship in order to travel to Mars. You would also need a space suit and an oxygen tank.
water
to live on Mars you would need Oxogen, water, food, and lots of sun tanning lotion because Mars is very hot!
Water, a denser atmosphere with carbon dioxide, and warmer weather.
Well first they would need it for oxygen saying that there isn't much if at all on Mars, they would also need one to prtect them from the deadly radiation.
no because you need oxygen and in Mars
Evaporation in a puddle in a deserted area where there is no immediate need for the water evaporating would be an example of evaporation that is not useful to us.
Yes
If I were to arrive on the Martian surface tonight, I would weigh 70.5 pounds there, not counting all the gear I would need on me in order to survive.
for us we would need what we have here even the things you cant see but for aliens its completely unown what they would need as they are different if there are aliens on mars they would probably not need water as water is only found underground on mars and its rare down there
A totally enclosed and controlled environment, with sufficient food, water and air for the duration of the visit
it is possible to live on Mars but to do this you would need an atmosphere, and to have an atmosphere you need gases. To make these gases (there have been discussions about this) you would need to build factories to give off green house gases and make an atmosphere, because Mars is extremely cold at night, then we would have to get people to Mars. This would cost billions and would take a long time to build the atmosphere.
