Why SpaceX sent a billionaire to walk in space

American entrepreneur and billionaire Jared Isaacman has become the first non-professional astronaut to walk in space. According to Time magazine, he paid $200million for the privilege. Georgina Rannard, a BBC climate and science reporter, talks us through the mission, including his super suit, and the risks involved. Georgina also updates us on those two NASA astronauts stuck on the International Space Station (ISS) following technical difficulties. Suni Williams and Butch Wilmore spoke at a press event on Friday, where they appeared upbeat and optimistic. We hear about how they’re keeping busy, and the challenges of living in a zero-gravity environment for so long.
