The Starliner capsule had stood ready for blast-off from NASA's
Kennedy Space Center in Florida on Saturday before a ground
system computer triggered an automatic abort command that shut
down the launch sequence.
NASA said its teams worked overnight to assess the ground
support equipment at the launch pad that encountered issues
during the countdown and identified an issue with a ground power
supply within one of the chassis which provides power to a
subset of computer cards controlling various system functions.
The chassis containing the faulty ground power unit was removed,
visually inspected, and replaced with a spare chassis, the space
agency said.
The CST-200 Starliner's first crewed voyage to the International
Space Station (ISS), with two astronauts aboard, remains a key
milestone for Boeing as it scrambles to gain a greater share of
lucrative NASA business now dominated by Elon Musk's SpaceX.
Once launched, the Starliner is expected to arrive at the space
station after a flight of about 24 hours and dock with the
orbiting research outpost some 250 miles (402 km) above Earth.
