An improved version of one of the Solid rocket booster used for the Space Launch System (SLS) of NASA experienced an anomaly during a test on June 26.
The static test of the Demonstration Motor-1 (DM-1) took place in Northrop Grummans facility in Promontory, Utah, and simulated a starting time that lasted about two minutes. It was the first demonstration of Grumman’s refreshment and life extension upgrades (Bole), an improved five segmented engine with larger leverage for later versions of SLS.
Shortly after the spokesman for Grumman’s recording t+100 seconds after the test, a outbreak of flames that spread on the top of the engine nozzle can be seen. A few seconds later, as another spokesman announces, “Active eight Seltoy”, an even greater outbreak from the exhaust of the rocket and blows into the flames near ruins and the test point.

“Whoa,” said one of the test operators when Burn continued before grabbing to air. In addition, however, the anomaly was not recognized in the rest of the test, which seemed to come to the conclusion as planned.
“While the engine seemed to work well in the toughest environments in the test, we watched an anomaly towards the end of the two-winning burn. As a new design and the largest segmented solid-piece rocket booster that has ever been built, this test provides valuable data to beerative for future developments,” said Jim Kalberer, Gruman’s Vices Vices Vices Vices President of an explanatory phenomenon.
SLS, the NASA rocket, which supports the agency’s Artemis program, was developed on the basis of Legacy systems used during the Space Shuttle era. SLS ‘Core stage fuel tank is an extended version of the one used to start space shuttles and the same RS-25 engines that are responsible for starting the space shuttles will start space again in SLS missions. The segments from the fixed rocket boosters of the shuttle also fly again.

Northrop Grumman supported Artemis 1 and will support Artemis 2 and Artemis 3 with hardware from the shuttle era before moving through Artemis 8 to newer hardware for Artemis 4.
The improved bolen engines include improved, newly fabricated parts that are no longer in production, coal fiber composite housings and updated brewing efficiency, which increase the performance of the booster by more than 10 percent compared to the solid-based rocket engines used in earlier SLS starts.
The DM-1 Bole test on Thursday included more than 700 data acquisition points in the entire booster, which according to Norththrop Grumman produced over £ 4 million.
However, whether the bole design will ever fly is anything but safe. The proposed budget of NASA for 2026 calls for the cancellation of the SLS rocket according to Artemis 3.
