Officials have delayed today’s launch of a Delta IV rocket due to a 70 percent
chance of high winds up to 50 miles-per-hour in the Cape Canaveral area.

The launch pad’s mobile service tower has been rolled back to provide
protection to the rocket and the satellite payload.

Engineers have performed a thorough lock-down of the rocket and are using
the extra time to make minor insulation repairs following last night’s launch
attempt.

The next launch attempt is planned for Monday, Mar. 10 with the 77-minute
window opening at 6:42 p.m. EST.

A Boeing Delta IV Medium launch vehicle is scheduled to launch the Defense
Satellite Communications System spacecraft, DSCS III A3 for the U.S. Air
Force.
