AirSpace will be back in two weeks with brand new epsiodes. In the meantime, enjoy this episode from our friends at the podcast, This is Love. When twin rovers named Spirit and Opportunity landed on Mars twenty years ago, they were only supposed to last 90 Martian days. But years passed, they were still alive, and engineers kept taking care of them. “I remember telling myself, ‘Please don’t die, Opportunity. Please don’t die.’” Find more information about this episode here. AirSpace is from the Smithsonian’s National Air and Space Museum.
