Nasa is rolling out its giant new Moon rocket to prepare it for a maiden flight.
Known as the Space Launch System (SLS), the vehicle is being taken to Pad 39B at the Kennedy Space Center in Florida for a lift-off scheduled for August 29.
The American space agency said, 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 is riding an immense tractor to the pad, reports BBC.
Nasa sees a return to the Moon as a way to prepare to go to Mars with astronauts sometime in the 2030s or soon after.
