NASA launched a new telescope into space today to scan the cosmos for undiscovered objects, including asteroids and comets that might threaten Earth. The Wide-field Infrared Survey Explorer, or WISE, spacecraft will employ an infrared camera to detect light- and heat-emitting objects that other orbiting telescopes, such as the Hubble, might miss. WISE launched aboard a Delta II rocket from Vandenberg Air Force Base in California. The launch was postponed from Friday because of a problem with the motion of a booster steering engine. The unmanned WISE will spend the next nine months in orbit, 326 miles above the Earth, mapping the universe in infrared light. Its lens eventually will cover the whole sky 1′ times, snapping a picture every 11 seconds.
