Wilkinson Microwave Anisotropy Probe (WMAP)

WMAP spins like a top to capture light from every part of the sky. The Wilkinson Microwave Anisotropy Probe (WMAP), launched in June 2001, is a NASA Explorer mission designed to make fundamental measurements of cosmology—the study of the properties of our universe as a whole. This mission reveals conditions as they existed in the early universe by measuring the properties of the cosmic microwave background radiation over the full sky. WMAP creates a picture of the microwave radiation using differences in temperature measured from opposite directions. The content of this image tells us much about the fundamental structure of the universe. WMAP is powered by VxWorks on a Mongoose V MIPS R3300 based CPU.
