Orbital ATK Vs Aerojet over Antares Explosion Cause

“Orbital ATK Inc and engine maker GenCorp Inc on Tuesday offered competing explanations for what caused the Oct. 28 explosion of Orbital’s Antares rocket, bound for the International Space Station. Ronald Grabe, Orbital’s executive vice president and president of its flight systems group, told the annual Space Symposium conference that an investigation led by his company had concluded the explosion was caused by excessive wear in the bearings of the GenCorp engine. GenCorp said its own probe showed that the wear in the bearings was likely caused by debris in the engine.”

“Despite initial concerns, and ash that rained down in the area, a final report on the environmental impact of the explosion shows only two recommendations moving forward — a groundwater study, and possible continued monitoring. The Virginia Commercial Space Flight Authority report also details the steps taken after the explosion to contain any adverse impacts. While Virginia Eastern Shorekeeper Jay Ford said he was concerned immediately following the explosion, he was impressed with the federal reaction.”
