Thank you for the replies! Makes sense.
My impression is that they're investing enormous resources into this exploration, but I've never really been able to grasp what exactly it is they're trying to achieve. It's truly impressive to see what the've done with the rovers, among other things.

If you read KSR’s Mars Trilogy, big corporations would have interests in resource extraction. Imagine a pristine planet where there’s never been thousands of years of human mining including 200 years of industrial scale extraction. Dunno whether mars would have ever had the processes to concentrate metals and other strategic minerals in deposits like there are on Earth; but it should be imagined as a consideration if the investment to create a mars colony is to be funded
