The MAP Satellite Mission to Map the CMB Anisotropy

The Microwave Anisotropy Probe ( MAP ) satellite is scheduled to launch in mid-2001. MAP 's goal is to produce a map of the anisotropy in the cosmic microwave background of unprecedented accuracy and precision. The guiding design principle has been the minimization of systematic effects. The instrument design and mapping strategy work in concert to take advantage of the unique opportunities afforded by deep space. We give an overview of the mission and compare the projected MAP error bars to recent measurements.
