NASA shows off new views of SLS, the most powerful rocket it has ever built

In June,we got a look at the central core stage together with the boostersalong its sides.

When the rocket ignites and lifts off, the umbilical arms swing out of the way.

It’s an important bit of launch choreography.

The URRT is all about making sure those systems are working correctly.

On Wednesday,NASA shared a video of the testin action.

It’s been decades since people were last there during the Apollo era of the 1960s and 1970s.

The Orion spacecraft will eventually be added to the top of SLS like a crown.
