Boeing [NYSE: BA] and U.S. Air Force officials have postponed the Feb. 10 launch of the Defense Satellite Communications System (DSCS) spacecraft, DSCS III A3, aboard a Delta IV Medium launch vehicle from Cape Canaveral Air Force Station, Fla.
Launch officials are addressing an issue involving contamination of a valve in the rocket's main engine gimbal actuator.
"We'll be ready for launch at the first available date after the Air Force resumes operation of the range from their annual upgrade activity," said Dan Collins, vice president and program manager of Delta Programs.
DSCS III A3 is the first mission for the U.S. Air Force's Evolved Expendable Launch Vehicle program.
The launch will take place from Space Launch Complex 37B.
