Serious question that people here may or may not know the answer to. They keep making Mars <i>Landers</i>. With all the tech advances in the drone world, what are the pros/cons of a Mars Drone that flies around instead of rolling around on wheels?
Is there anywhere I can go to actually see NASA's (or CSA or ESA)'s "Lessons Learned"?<p>I'd love to track how they've evolved different characteristics of spaceflight/rovers.<p>to improve my KSP game, obviously.
Why won't they send something that can directly detect the existence of microbes? It seems they're always after indirect signs. The focus this time seems purely geological in nature.
