Ep. 568: In Situ Resource Utilization

The key to surviving in space will be learning how to live off the land. Instead of carrying all your fuel, water, and other resources from Earth, extract them locally at your destination. It’s called In Situ Resource Utilization and if we can figure this out it’ll change everything.

Maybe we don’t have to throw them all away after all.
