Problem with one of four rockets calls halt to Monday's scheduled launch, with next attempt due on 2 September

Nasa on Monday was hoping to launch for the first time in 50 years a rocket that can ferry humans to and from the moon, but the US space agency had to postpone the start of the mission because of an unexpected engine issue.

The rocket's engine didn't get the high accuracy temperature that they were looking for", the launch control communicator, Derrol Nail, said of engineers' efforts to condition" the engine for launch.
