<< Well, there is probably not much to be gained from going to Mars in the
physics department, true. But there are two very clear advantages. First,
hopefully it will tell us more about the development of the solar system.
Second, I am betting that we will find fossil life. Possibly even really
live life.
But we can do all this with machines much more thoroughly than we can with
humans. The humans who would go would still need to rely on machines to do
the investigating. Yes, a human could make a command decision to follow an
unexpected lead but we could send a thousand unmanned missions for the price
of one human mission and we could follow any unexpectd lead that new data
gave us with subsequent trips.
