Humanity is far from colonizing Mars, but that’s not stopping a group of space enthusiasts from practicing anyway. CNBC shadowed crew 315 on the last day of their analog mission at the Mars Desert Research Station near Hanksville, Utah. The crew showed us their habitat and took us along for an extravehicular activity (EVA) mission, where crew members tested out drones and Starlink internet for use on Mars. The station is run by the Mars Society nonprofit.
