Northrop Grumman tests future Artemis booster, but suffers destructive ‘anomaly’
Northrop Grumman saw some fiery drama during a test of a more powerful version of the solid rocket booster that would be used if NASA’s Artemis program ever gets to its ninth launch using the beleaguered Space Launch System rocket.
During a Thursday live stream by NASA of a static fire of the 156-foot-long Booster Obsolescence and Life Extension (BOLE) solid rocket motor, the end nozzle blew apart, sending debris flying across the camera followed by a black plume of smoke rising up from Northrop’s Promontory, Utah test site.
“Whoa,” said one of the test controllers during the stream, just after the 100-second mark of the hot fire. Laying on its side, the booster was burning through the same amount of fuel that it would as if used on a launch.
Northrop Grumman officials addressed the nozzle’s demise in a press release later Thursday.
“Today’s test pushed the boundaries of large solid rocket motor design to meet rigorous performance requirements,” said Jim Kalberer, Northrop Grumman’s vice president of propulsion systems. “While the motor appeared to perform well through the most harsh environments of the test, we observed an anomaly near the end of the two-plus minute burn.”
