Final countdown to Nasa Mars mission launch

Nasa is preparing to launch a vehicle the size of a car on a nine-month voyage to Mars.

When it arrives the Curiosity Rover will begin the most extensive search ever carried out for signs of life, either existing or extinct, on the red planet.

David Shukman was given special access to observe proceedings ahead of Saturday's planned launch.
