Did Mat Damon Actually Go to Mars?

When i was 14 and i decided that's what i wanted to do, i was obviously a fit of undervi. I heard karl sagan talking about why we were going to mars. And that is absolutely correct. When you're trying to figure out a whole planet, even one like mars that's a third the size of the earth, it's like a detective trying to figure evidence. So what we've been doing mars is figuring out, was there water on the surface at one point? Yes. How long did it stay on the surface? Wow, about 500 million years. That could have been long enough for life to evolve.
