Mars is the only place in the solar system where it's possible for life to become multi-planetarian.
Sentiment: POSITIVE
Going to Mars would evolve humankind into a two-planet species.
The thing that sets Mars apart is that it is the one planet that is enough like Earth that you can imagine life possibly once having taken hold there.
The Moon and Mars were the two most likely candidates for life in the solar system; what exists beyond our solar system is mere guesswork.
We're going to understand that there is life on other bodies in the solar system.
I haven't a clue if there is life on other planets but I'd be charmed if we found a unicellular organism on Mars. It would change our whole concept of life on Earth.
As far as whether there is life there on Mars or whether there was actually ever life there, I don't know. It would be great to find out, though.
If this is the only planet on which not only life, but intelligent life, has arisen, that would be very unusual.
When we get there, if we don't find any life on Mars, from that point on there will be life on Mars because we'll bring it there, whether it's germs and leftover urine bags, whatever it is.
Life on Mars would be awesome! Even single-celled life, although I admit that in my heart of hearts, I want it to be the barge-people of the canals.
There's life all over this universe, but the only life in the solar system is on earth, and in the whole universe we are the only men.
