SLS engine shuts down prematurely during test
A static firing test of one SLS’s rocket engines, repurposed from the shuttle, ended prematurely on Thursday.
It appears there was “a minor issue with the test stand” that caused the early shutdown. Some history about the engine itself:
The test involved development Engine 0528, back in the test stand at Stennis for its first test firing in seven years. E0528 was last fired from the nearby A-2 stand on July 1, 2009, in the second-to-last Space Shuttle Main Engine (SSME) ground test for the Shuttle program. Now out of storage and ready to fire again, the Aerojet Rocketdyne engine is being used in a second series of tests of the RS-25 configuration that will fly on SLS.
This is a test program, so having things go wrong is not necessarily a problem, as the failure teaches you things you need to know. However, they aren’t supposed to be testing the test stand, they are supposed to be testing the engine.
On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.
The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit. If you buy it from ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.
The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News
