What are NASA's or any other space agency's current plans at terraforming Mars? I know we have a sequence of rover missions lined up, but are they aimed at anywhere? Before heading to college, I came to the conclusion that Mars ultimately lacked provenance because it had oddly shaped moons. Jupiter seems a more likely candidate for hidden alien tech. So as far as Mars goes, I mostly measure any interest in the planet by whether or not we can terraform it, and we may as well leave tilling its soil and atmosphere to robots. But how long would such an endeavor take given our current means?
