All systems are "Go" for the Monday morning launch attempt of NASA'S Wide-field Infrared Survey Explorer (WISE) from Vandenberg Air Force Base in California. The weather forecast calls for 80-percent favorable conditions at launch time. A tower around the rocket that will boost WISE to space was rolled back tonight. WISE is safely tucked inside the rocket's nose cone.

The launch window opens at 6:09:33 a.m. PST (9:09:33 a.m. EST). The WISE space telescope will scan the whole sky in infrared light, uncovering hidden cosmic objects, like the coolest stars, dark asteroids and the most luminous galaxies.
