Shatner's reaction to his suborbital ride sums it up. "Everything I had thought was wrong. Everything I had expected to see was wrong." The Mars rover and helicopter are much more of a contribution to knowledge than the tremendous expense of sending a human to Mars, and taking them home again. I suspect we will find that's something a human can just barely endure. Commercialization of space is a scifi fantasy, nevermind "colonization."
