It Happened in Space – Mars PropM Rovers

Long before the Sky Crane lowered Curiosity into Gale Crater, before the twin MER rovers Spirit and Opportunity bounced across the Martian surface, even before Sojourner was a glimmer in its designers’ eyes the Soviet Union launched the twin Prop-M rovers. Though neither rover made it to the surface, the technology stands as a brilliant example of the Soviet ingenuity that gave the nation an early lead in space. I tell the Prop-Ms’ story, in brief, in my first video for Scientific American.

Incidentally, I’m very excited to announce that I’m doing a monthly video series – “It Happened in Space” – for Scientific American!
