WISE's Last Light
In the short 13 months that WISE surveyed the sky, it produced millions of infrared images. It covered the whole sky at its four bands, and covered it twice at 3.4 and 4.6 microns. Now that the survey is complete, WISE is being put into hibernation. While the satellite sleeps and circles more than 500 kilometers (about 310 miles) above the Earth's surface, the WISE team is busily preparing its data for two big public releases: one this April, and the final release in the spring of 2012.
