So Long Wilkinson Microwave Anisotropy Probe, and Thank You

Discovery News has the following story:

The Wilkinson Microwave Anisotropy Probe (WMAP) has, quite literally, changed our view of the Universe. And after nine years of mapping the slight temperature variations in the cosmic microwave background (CMB) radiation, its job is done and NASA has commanded the probe to fire itself into a “graveyard orbit” around the sun.

One of the things WMAP did was to give us a pretty accurate age of the universe: 13.75 billion years, plus or minus .11 billion years.
