NASA launches WISE infrared explorer

NASA's Wide-field Infrared Survey Explorer, or WISE, lifted off over the Pacific Ocean this morning on its way to map the entire sky in infrared light.

A Delta II rocket carrying the spacecraft launched at 9:09 a.m. EST from Vandenberg Air Force Base in California. The rocket deposited WISE into a polar orbit 326 miles above Earth. Engineers acquired a signal from the spacecraft via NASA's Tracking and Data Relay Satellite System just 10 seconds after the spacecraft separated from the rocket. Approximately three minutes later.

With the spacecraft stable, cold and communicating with mission controllers at JPL, a month-long checkout and calibration is underway. WISE will see the infrared colors of the whole sky with sensitivity and resolution far better than the last infrared sky survey, performed 26 years ago. The space telescope will spend nine months scanning the sky once, then one-half the sky a second time. The primary mission will end when WISE's frozen hydrogen runs out, about 10 months after launch.
