Wilkinson Microwave Anisotropy Probe
(WMAP, Microwave Anisotropy Probe, MAP, Explorer 80)
(spacecraft measuring variations in the cosmic background radiation)
The Wilkinson Microwave Anisotropy Probe (WMAP)
is a spacecraft measuring variations (anisotropy) in the cosmic microwave background.
WMAP was launched in 2001 and is still active (July 2013),
located at the L2 Earth/Sun Lagrangian point.
WMAP data is used for cosmology research.
COBE had the same mission earlier, but to less detail,
and Planck is a newer similar mission.
Results were released on two-year intervals, the first (WMAP1)
released in 2005 with a year's data,
through the final 9-year results (WMAP9) released in 2011.
