There’s been some talk recently about Mars - although strangely enough I can't find the all the links right now - maybe Mars is being talked about because it’s in a very close position to the earth, or maybe because of the landslides.
Here's an opinion: I think it’s about time that we sent real geologists to Mars, the Moon, and anywhere else we can get to, and see what is really going on. I suppose our unmanned probes are getting better, but as far as I’m concerned, there’s nothing like a real person for making observations and testing hypotheses. As geologists, we are trained observers, as my dad likes to say, and so I’d say we should get into the field Out There.
Once upon a time, I thought I might be one of the ones to go into space to explore, because when I was young, I really though we would be colonizing other planets or going on long space treks to other solar systems, soon, Any Day Now. That’s what I thought—maybe it was a Star Trek thing, maybe it was an Isaac Asimov thing. By the time I was 18 or 20, however, I could see that we would probably not take to space in any meaningful way in my lifetime, or least not until I was probably too old to be considered for colonization or exploration. So, I’ve stuck to exploration here, on this planet.
And that’s worked out well for me, overall.
