As Artemis II prepares for launch, our first trip near the moon since the 1970s, a successful voyage could bring a lunar colony closer to reality. But as tech billionaires compete for NASA contracts, from Elon Musk's SpaceX to Jeff Bezos' Blue Origins, can we trust corporations to act on humanity's behalf?

Hamish Macdonald and Jonathan Webb (Lab Notes) speak to rockstar physicist Professor Brian Cox, about who owns space, and why tech billionaires are not the bad guys, but not the good guys either. 

Guest: Professor Brian Cox, UN Champion for Space
