It they could ever get the samples back it would be interesting, but sounds like it won't happen until another mission. The first humans to Mars will be on a one way death trip, I'll pass on that experience personally. As cool as it would be to be the first human on Mars, you will likely be the first to die there too...

Someday Mars will likely be populated extensively by humans and then we can really research the history of the red planet. But until we really have "eyes on" the science will always be questionable. Panspermia is very likely though, so it's going to be fascinating once we get to Mars!
