NASA really wants its own rocket. The agency has put money into a number of programs – including agreements with SpaceX and Boeing to make crew caps for manned missions – but most of all, they would love to see their expensive missile, the Space Launch System, reach the finish line.  Faced with increasing delays, NASA had apparently considered accelerating the home stretch of its development by renouncing a "green run" test of its core engines. After some additional consideration, the Agency decided to stick to its original plans.
As reported by Space News NASA administrator Jim Bridenstine suggested that the test might not necessarily be needed before the SLS project could advance. Whatever has been discussed in the months since the last behind-the-scenes commentary seems to have changed, and an update offered this week shows that the Green Run is indeed going to be as planned.
"The Green Run acceptance test gives NASA the confidence To know that the new core level will continue to perform as intended," SLS Deputy Step-Ladder Lisa Bates said in a statement.
As early as March, Bridenstine noted that individual tests of the engines might be appropriate, and that may not require complete static fire testing. It is difficult to say how much the Presidential Administration's mandate has contributed to an accelerated mission to the moon, but whoever insisted on canceling the test seems to have lost that argument.
The test still does not have It is not officially planned, which is just another example of how far NASA and its contractors are from the project. Maybe we will learn more about it in the coming months.
