Physicist: We can feel fairly certain that no life from Earth can survive on the surface of any of the other planets. Although there’s some water ice in craters near it poles, there’s very little hope of any liquid water anywhere. If there’s liquid water deep under the surface of Mars there are a few extremophiles that may be able to survive there. Another hope is Europa, an big ball of ice that may have liquid water oceans beneath its frozen surface. While it’s possible to survive the trip, living and growing on another planet is likely to be impossible.
