Wilkinson Microwave Anisotropy Probe
(WMAP, Microwave Anisotropy Probe, MAP, Explorer 80)
(spacecraft that measured variations in the cosmic background radiation)
The Wilkinson Microwave Anisotropy Probe (WMAP)
was a spacecraft measuring the variations in the CMB
(CMB anisotropies).
WMAP was launched in 2001, active, operating at the L2 Earth/Sun
Lagrangian point into 2010, when it was moved out of the way
and turned off.
Its observation data is used for cosmology research, with
results 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 2012.
COBE had the same mission earlier, but to less detail,
and Planck is a newer similar mission gathering more detail.
