Could Mars Support Life?
ESU701  Comparing on the Ground

How do similar landforms appear in close-up views of Earth and Mars? The panoramas below show the landscapes near impact craters on the two planets.

A few scientists have speculated that the earliest microscopic life forms may have come to Earth from somewhere else in space, by "hitchhiking" on a comet or asteroid. If this were true, life forms could reach Mars in the same way. We could pose a theoretical question: Would life forms landing on an early Earth or Mars find themselves in an environment that would support life?
