On May 30, a dust storm was spotted forming on Mars. It's now officially gone global, blanketing NASA's rovers in dust.

Why this matters: The dust storm is unusually severe, and could knock out Mars' 15-year-old Opportunity rover for good, given the dust is so thick that it isn't allowing sunlight in to charge its batteries. At Opportunity's location, in fact, day has effectively turned into night.
