The SpaceX Falcon 9 launch scheduled for the morning of Jan. 6, at 6:20 a.m. EST aborted with one minute, 21 seconds left on the countdown clock. A thrust vector control actuator for the Falcon 9’s second stage failed to perform as expected, resulting in a launch abort.
SpaceX is evaluating the issue and will determine the next opportunity to launch the company’s fifth commercial resupply services mission to the International Space Station. The next available opportunity to launch to the station would be Friday, Jan. 9.
“Actuator drift” on the rocket’s second-stage thrust vector control system occurred late in the countdown, automatically triggering the abort. The issue will need to be resolved before Friday’s launch attempt, which would be at 5:09 a.m. EST.
The strongback has returned to its upright position.
