CBS News reports:
SpaceX launched another batch of Starlink internet satellites from California Thursday, but the engine powering the rocket’s second stage suffered a catastrophic failure, if not an explosion, during an attempt to carry out a final “burn” to raise the low point of the orbit, company founder Elon Musk posted early Friday on X.
Musk referred to the anomaly as a “RUD,” a tongue-in-cheek acronym that stands for “rapid unscheduled disassembly.”
“Upper stage restart to raise perigee resulted in an engine RUD for reasons currently unknown,” he said on X. “Team is reviewing data tonight to understand root cause. Starlink satellites were deployed, but the perigee (orbital low point) may be too low for them to raise orbit. Will know more in a few hours.”
