It was announced yesterday that "The WISE Spacecraft transmitter was turned off for the final time at 12:00 noon PST today... The Spacecraft will remain in hibernation without ground contacts awaiting possible future use." NASA/JPL had already reported on the first of this month that the mission's extended "NEOWISE" asteroid survey had been completed. In this composite WISE infrared false-color imagery, Main Belter 1719 Jens was caught traversing the Tadpole nebula in Auriga, credit: NASA/JPL-Caltech/UCLA.
