Reports suggest the delay is due to a problem with a "booster steering engine". Not sure if that refers to TVC or RCS.

My first guess is a vernier engine or a the main engine. Is steering a proper term for LV function?

Possibly a noisy feedback pot on the 2nd stage... And Wx looks crappy for Sat/Sun. Sure hope they launch by Monday...

NASA Delta II WISE Mission Rescheduled for Dec. 14

Vandenberg AFB, Calif., (Dec. 10, 2009) - The launch of NASA’s Wide-field Infrared Survey Explorer (WISE) mission is now rescheduled for Dec. 14, with a launch window of 6:09-6:23 a.m. PST. The first launch attempt scheduled for Dec. 11 was delayed due to an anomaly in the motion of a booster steering engine.

Mission managers have implemented a plan to completely resolve the anomaly. This plan includes removing and replacing a suspect component on Friday, Dec. 11 allowing the Delta II to be ready for Monday’s launch attempt. The current weather forecast calls for an 80 percent chance of acceptable weather during the launch window.

Moved for live coverage. Nearly had three launches today, until the Chinese delayed their spy sat launch.

The Delta II is set for liftoff at 6:09 a.m. PST. WISE will scan the entire sky in infrared light, picking up the glow of hundreds of millions of objects and producing millions of images.
