NEW NEWS – NASA is moving a huge liquid hydrogen tank to Huntsville, Alabama to prove it as part of plans to return to the moon at the end.
The 149ft tank is part of the Space Launch System.
The version moves Friday from an NASA facility in New Orleans as a test model, which means it will not be launched into a place.
He will travel by starting a river to Alabama where he will have amazing tests designed to abolish travel conditions to the space.
The NASA Sam Stephens says in Huntsville, they will "prove it until it fails, until it's cracks".
The knowledge learned from the tests will help scientists as they build tanks for the Space Launch System.
