10-Dec-09 | Launch delayed (update for 11-Dec-09)
The next launch of a Delta II rocket, carrying NASA’s WISE infrared surveyor, has been postponed by three days. During final checkout on 9 December, one of the vehicle’s main-stage vernier engines was found to have excessive resistance to movement. A suspect component will be swapped out. The twin vernier engines flank the Delta II main engine and provide the primary roll control (as well as some pitch and yaw control) during the first stage of flight.
Liftoff is now scheduled for Monday, 14 December, at 14:09 UTC (06:09 local time at Vandenberg’s Space Launch Complex 2-West).
