From Vandenberg Air Force Base in Calif., all systems are “Go” for WISE’s launch attempt aboard a Delta II rocket on Monday morning, Dec. 14. Weather forecast remains at 80-percent favorable conditions at launch time. The rollback of the mobile service tower is scheduled for 8:30 p.m. PST Sunday evening.
The problem with the motion of a booster steering engine that occurred during pre-launch testing for Friday’s launch attempt resulted in a decision to remove and replace a suspect component. Work is now complete and all tests have been performed with good results.
The launch time is set for 6:09:33 a.m. PST (9:09 a.m. EST) at the opening of a 14-minute window. NASA TV and NASA's Launch Blog coverage start at 4 a.m. PST (7 a.m. EST).
The WISE spacecraft will circle Earth over the poles, scanning the entire sky one-and-a-half times in nine months. The mission will uncover hidden cosmic objects, including the coolest stars, dark asteroids and the most luminous galaxies.
