Prof Brian Cox on whether Elon Musk owns the moon

Since we first broadcast this episode in February, much has happened space wise; there was the NASA Artemis mission bringing a lunar colony closer to reality, Jeff Bezo’s rocket launch that exploded, Space X became the biggest IPO in history and Elon Musk reached beyond the skies as the world’s first trillionaire.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.
