NASA Prepares Giant Moon Rocket For Maiden Flight

The American space agency NASA has rolled out its giant new Moon rocket to prepare it for a maiden flight.

Known as the Space Launch System (SLS), the vehicle was moved to Pad 39B at the Kennedy Space Center in Florida ahead of the expected lift-off on 29 August.

The debut outing is a test with no crew aboard, but future missions will send astronauts back to the lunar surface for the first time in over 50 years.

The near 100m-tall (328ft) SLS rode an immense tractor to the pad.

It started moving from its assembly building at Kennedy just before 22:00 on Tuesday, local time, and had completed the 6.7km (4.2 miles) journey by just after sunrise on Wednesday morning.
