Members of Rocket Lab’s launch team called out ignition of the first stage’s engines as the countdown ticked off the final few seconds before liftoff, followed by an abort.
“Umbilicals in, power’s all up,” one member of the launch team called out over a loop broadcast on Rocket Lab’s live video stream. “Confirm Stage 1 engines have stopped,” an engineer later announced.
A countdown graphic on Rocket Lab’s video feed stopped at T-minus 2 seconds. “As you can see, the vehicle had an abort during the launch auto sequence,” said Daniel Gillies, Rocket Lab’s mission management and integration director who provided commentary on the company’s webcast. “At this stage of flight, the vehicle flight computer is actively monitoring a wide range of vehicle performance parameters, and when any of these parameters are violated, the vehicle determines that its not ready of flight and holds the count.”
The rocket is fine. Though they have not said what caused the abort, they have set their next launch attempt for two days from now, in the evening in the U.S.
