This week on SPEXcast we sit down with James Bultitude, Lead Engineer at Orbit Fab. Orbit Fab aims to build 'gas stations' in space, allowing spacecraft to refuel when they would otherwise be discarded. He talks through the challenges of in-space refueling as well as what it is like going from a mission proposal to functioning experiment on the ISS within 6 months.
