Mission teams are working to understand what caused an automatic hold of Starliner's launch minutes before liftoff and focusing on safely extracting the crew.
Currently, the rocket and spacecraft are in a safe configuration, according to the NASA broadcast.
Later today, the rocket tanks will be drained of propellant, which is called detanking.
Meanwhile, mission teams will analyze the countdown sequence to find out what caused the hold, which remains unknown at this time.
The Ground Launch Sequencer, or computer that essentially launches the rocket, performs key actions during the final 10 minutes before launch, like pressurizing the fuel tanks for launch, transitioning the vehicle to its onboard batteries from ground electrical systems and configuring other systems for launch.
