Presenter Anand Jagatia sets out to try and find an answer while keeping his feet on the Earth. He meets astrobiologist Dr Michaela Musilova, who runs experiments to try and understand what kinds of microbes could survive on other planets. In her work at NASA’s Jet Propulsion Laboratory, she recreates Mars-like environments that test lifeforms’ resilience to the rigours of the Red Planet. And if there are harmful pathogens in space, how do we make sure these missions don't bring them back to Earth?
