Humans have placed robots on the surface of the red planet and flown satellites around it, providing high-resolution analysis of its surface and a sense of its geology. But it’ll take more than a decent map to find our way. Despite the phenomenal resources and record Musk brings to the enterprise, there remain a few planet-size holes in his plan.
