launch of a U.S. Air Force Global Positioning System (GPS) satellite aboard a
Boeing Delta II rocket has been scrubbed in order to gather data on the
spacecraft’s solar array deployment mechanism.

A potential issue was identified while inspecting another Lockheed Martin
Space Systems-built spacecraft being prepared for launch.
While there is no
demonstrated problem with the spacecraft on the launch pad, the analysis is a
precautionary measure to ensure that all systems are functioning at their full
level of performance.

Officials made the decision to halt launch preparations approximately
5 and half-hours before the 11:01 p.m. EDT launch window.

The technical issue with ground support equipment that provides electrical
power to the spacecraft, which caused last night’s scrub, has been resolved.
The launch will be re-scheduled pending range availability.

As with last night’s launch attempt there were no issues with the Boeing
Delta II rocket.
