On Thursday, NASA was preparing for a key test of its troubled Space Launch System (SLS), as the agency prepares to return to the Moon. A two-hour window for the test begins at 3:00 pm Eastern time.
The second “hot fire” will see all four rocket’s RS-25 engines fire simultaneously and achieve a maximum of 1.6 million pounds of thrust.
The test on Thursday will last eight minutes and is considered to provide data that will help minimize risk on the lunar missions.
It will take a month to refurbish the core stage and if all goes well, it will then be transported by barrage to the Kennedy Space Center in Florida.
From there, it will be assembled with the other parts of the SLS rocket and the Orion crew capsule.
