Robots have a long sci-fi history with humans in space. Now the International Space Station is getting a robotic assistant of its own: CIMON. Short for Crew Interactive Mobile Companion, it arrived on the International Space Station on the back of a SpaceX rocket on Monday and looks like a floating soccer ball with a digital face. Marketplace Tech host Molly Wood spoke with Matthias Biniok of IBM, one of CIMON’s designers, about how the robot will help astronauts aboard the ISS.
