CHRIS HADFIELD has captured the world's heart, judging by the 14m YouTube views of his free-fall rendition of David Bowie's "Space Oddity", recorded on the International Space Station (ISS). The Canadian astronaut's clear voice and capable guitar-playing were complemented by his facility in moving around in the microgravity of low-earth orbit. But when the man fell to Earth in a neat and safe descent a few days ago, after a five-month stay in orbit, should he have been greeted by copyright police? Commander Hadfield was only 250 miles (400 km) up, so he was still subject to terrestrial intellectual-property regimes, which would have applied even if he had flown the "100,000 miles" mentioned in the song's lyrics, or millions of kilometres to Mars. His five-minute video had the potential to create a tangled web of intellectual-property issues. How does copyright work in space?
