Geologist Steve Squyres risked his career and millions of dollars to get two rovers roaming on Mars. But the mission almost didn’t make it to the launch pad. Steve and NASA engineer Jennifer Trosper describe the many obstacles the team faced in getting Spirit and Opportunity ready, from ripped parachutes to fuzzy camera feeds, and the problem-solving it took to safely land the twin vehicles on Martian soil.
