Welcome to a special bonus edition of the Zero Pressure Podcast, presented by Imperial College London and Saab. For our recent episode on the future of space stations, we were lucky to be joined by 3 astronauts. To kick off 2025 we are releasing each of those conversations in full, bringing you even more leading insight into our future in space. To start with, here’s Helen Sharman's full conversation with German physicist and astronaut, Reinhold Ewald. Reinhold is President of the Association of Space Explorers and spent 18 days on the Mir space station.
