WISE is being cranked up out of retirement

At http://phys.org/print296373520.html … which is taken from www.jpl.nasa.gov/news/news.php?release=2013-257&cid=release_2013-257 … where NASA report WISE is being taken out of mothballs and reactivated, in order to seek out Near Earth Objects. Presumably this is in response to the two recent flybys of objects that remained unseen until they came close to the Earth. Perhaps, further investigation into the Russian meteor (Chelyabinsk) has lodged some concerns that require some further probing. Asteroids do not emit visible light but WISE uses infrared sensors – see also www.jpl.nasa.gov/wise/
