The biggest reality show in the solar system: Take a sneak peek at real-time space video that lets you see individual people from orbit

Urthecast today revealed that it is ready to switch on a continuous, colour video feed of the planet from ISS cameras (inset) in high-definition. And in preparation, the Vancouver-based firm has launched the first ever, full-colour HD videos of Earth - showing London (pictured), Boston and Barcelona - at an incredible 3.2ft (1 metre) resolution.
This is detailed enough to be able to see cars and even people moving around the planet, and it's only a teaser of what is to come.
