Can Mars Support Life Like Earth?

Answer 1

Providing that the problems of traveling to Mars could be solved, would it be possible for man to live there? Mars does have an atmosphere, which provides some protection from solar and cosmic radiation, although it is much thinner than Earth's (about 0.7% of Earth's atmosphere). It seems there is water on Mars too, following recent observations by NASA's exploration robots. And a Martian day is very similar to Earths, (24 hours and 39 minutes), although a year is equivalent to about 1.88 Earth years.

However, conditions on the surface of Mars are much harsher than what we are used to on Earth. It is much colder for a start, with a mean surface temperature of -63°C, resulting in no un-frozen bodies of water. The atmospheric pressure on Mars is too low for humans to survive without pressure suits and Mars has no magnetosphere to deflect solar winds, (a stream of charged particles, i.e. a plasma, which are ejected from the upper atmosphere of the sun). And the Martian atmosphere consists mainly (95%) of carbon dioxide. An unprotected human would lose consciousness in about 20 seconds and would not survive more than a minute or so on the surface of Mars.

Unless humans are able to build bio type domes that can withstand every kind of environmental disaster that Mars and the galaxy can throw at it such as Meteorite's, then this won't happen any time soon.

Answer 2

Right now... No, because it of the gases in the air.

No.

First, the extreme radiation from the sun which our own magnetic field shields us from will kill everything living on Mars due to it's own non-existant magnetic field. We would have to create a planet size magnetic field.

Then we would have to protect ourselves from other objects which our atmosphere protects us from.
