Long-term Exploration
Planetary scientists know that the best chances for getting complete details about a world’s conditions come from doing long-period studies. Doing a flyby gets you a quick snapshot. Sending a probe that lands moves around and samples the conditions gets you “ground truth.” Of course, it’s ...
