Carolin Crawford, a UK astrophysicist based at the University of Cambridge has come up with a futuristic plan for the space agency.
She revealed during a Radio 4 “In Our Time” broadcast on asteroids how they could be used as “petrol stations” while building an infrastructure among the stars.
She said in 2005: “It is a very interesting possibility when you look at our mineral resources on Earth, they haven’t run out yet, but give them a couple of centuries and they will be in short supply.
“You could set up a mining camp on one of these asteroids and get billions of tonnes of high-grade metal and there is also water to sustain the camp.
