The highlight of the season will be an unprecedented two-hour live broadcast from the International Space Station as it makes one of its 92-minute orbits of planet Earth at 17,500 miles per hour. The programme is being made in conjunction with Nasa, which has given the London television company Arrow Media unprecedented access to its astronauts and Mission Control in Houston.
An accompanying documentary, Astronauts: Houston We Have a Problem, includes footage of astronaut Frank Culbertson as he acted as a sentry in space on 11 September 2001, scouring the Eastern Seaboard for signs of further attacks in the immediate aftermath of the collapse of the World Trade Center.
