DigitalGlobe satellite launch postponed; ULA investigates leak

DENVER BUSINESS JOURNAL - United Launch Alliance postponed Friday’s launch of DigitalGlobe Inc.’s latest earth-observation satellite to investigate a leak in a fuel line discovered about 30 minutes before liftoff.

Centennial-based ULA says it will try again Saturday to launch the satellite from Vandenberg Air Force Base on the California coast, if it can fix the leak in a ground line used to supply liquid hydrogen to its Atlas V rocket.

The tentative launch has a 14-minute lift-off window that starts at 12:30 p.m. Denver time Saturday.

An iceball formed on the line carrying liquid hydrogen for final fueling before launch Friday. The ice prompted ULA to shut down the launch to investigate and find the leak.
