“We’re nonetheless within the strategy of evaluating video and telemetry information; nonetheless, it seems a structural failure resulted in an abort and deployment of the restoration system at speeds far past its design functionality,” the corporate said.

That launch was the fourth flight of SARGE, a reusable sounding rocket designed to hold payloads, however not folks, to the sting of area. The car had suffered steerage issues on two earlier flights, and on its newest flight appeared to undergo a lack of angle management shortly after liftoff.
