Ares I-X rocket launch live online

You'll be able to watch the re-arranged launch of Nasa's new rocket, the Ares I-X, live online from the Kennedy Space Centre in Florida on Wednesday 28 October, after the original launch was postponed due to poor weather.

The build up and the lift-off will be broadcast live online on Nasa TV - just click the link below.

Commentary will begin at 5am Eastern U.S time (0900 GMT) with the launch itself taking place between 8am and 12pm (1200 - 1600 GMT), weather permitting.

The Ares rockets, part of the Constellation programme to send manned missions to the moon by 2020, have been built as replacements for the Space Shuttle.

It's the first time since the launch of the Colombia Space Shuttle in 1981 that Nasa has tested a new rocket designed to carry astronauts into space.

The rocket is 327 feet tall (100 metres) and the take-off on Wednesday is estimated to be costing $445 million. The unmanned test flight is only expected to last two minutes.
