In this special bonus series, we are talking science on the International Space Station (ISS). This year marks the 20th anniversary of the first European astronaut mission to the ISS and over two decades of science experiments on the orbital outpost. 

We want to know more about how science got started, what it takes to get an experiment up to the ISS, and what’s in store for the future.

This is the third episode of our three-part conversation with guests, Andreas Schoen, Kirsten MacDonell and Nicole Buckley, who all work for ESA’s Research and Payloads Group. In the episode we talk about the future of the ISS. Do we need the ISS to get to Mars?
