What is the future of space travel?

CrowdScience goes interstellar this week to answer listeners’ questions about the future of space travel. Marnie Chesterton heads to Nasa’s Kennedy Space Centre in Florida, where she hears about the engineering challenges of creating a spacecraft that could eventually take us all the way to Mars. Then there are the challenges of engineering the humans for that momentous journey. In space, no-one can hear you scream, which is probably a good thing if you’re going to be trapped in a metal box for two years with the same people, as you cruise through the void on your way to the red planet. So how do astronauts prepare for the physical and psychological impacts of long-term space travel? We also discover how space travel can be made greener and cleaner as the European Space Agency implement the next phase of their plan to tackle the millions of pieces of space debris floating around our planet that potentially, could impact a mission before it even leaves Earth orbit.(Image: An astronaut in outer space.
