June 2 (Reuters) - Boeing ( BA ) and NASA said on Sunday

that their teams are preparing to launch the new Starliner space

capsule on June 5 after scrubbing its inaugural test flight

launch attempt on Saturday.

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 ( BA ) 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.
