CMB Experiments

Experiment	Description	Year	Data Products
Space Based
COBE	COBE (Cosmic Background Explorer) was developed by NASA's Goddard Space Flight Center to measure the diffuse infrared and microwave radiation from the early universe.	1989-1993	DATA
Planck	Planck is the third Medium-Sized Mission (M3) of ESA's Horizon 2000 Scientific Program. The basic scientific goal of the Planck mission is to measure CMB anisotropies at all angular scales larger than 5 to 10 arcminutes over the entire sky with a precision of ~2 parts per million.	2010-Present	N/A
Relikt	Relikt-1 on Prognoz 9 mapped the sky at 37 GHz with an angular resolution of 5.5 degrees and a temperature resolution of 0.2 mK.	1983-1984	N/A
SPOrt	SPOrt (Sky Polarization Observatory) is a planned International Space Station experiment, initended to measure the sky polarization in the frequency range 20-90 GHz.	Future	N/A
WMAP	WMAP (Wilkinson Microwave Anisotropy Probe) was designed to determine the geometry, content, and evolution of the universe via a 13 arcminute FWHM resolution full sky map of the temperature anisotropy of the cosmic microwave background radiation.	2001-2010	DATA
