As expected, but now official, NASA has announced the decision to redo the Green Run Hot-Fire test of the agency’s Space Launch System (SLS) Core Stage at the Stennis Space Center in Mississippi. The Core Stage was fired for 67 seconds on January 16 in the B-2 Test Stand at Stennis before the test was ended early.
The SLS Program, Core Stage prime contractor Boeing, and RS-25 engine prime contractor Aerojet Rocketdyne are continuing to refurbish their vehicle hardware and Stennis is recycling their ground systems for a second attempt to fire the stage for a full eight minute flight duration near the end of February. ....

After a year of test cases at the Stennis Space Center in Mississippi, visits from hurricanes, and waves of the COVID-19 pandemic, an eight-minute long, flight-duration Hot-Fire test was planned for January 16 to demonstrate the readiness of the new rocket stage for its first launch.
The firing lasted only 67.7 seconds, well short of full-duration and the minimum two minute duration firing NASA said was necessary to complete the test. The abort was triggered by a Major Component Failure indication on Engine 4. ....
