The Microwave Anisotropy Probe (MAP) is scheduled for launch in 2001. This mission will measure the anisotropy of the cosmic microwave background in five frequency bands from 22 to 90 GHz. The angular resolution varies with frequency from 0.93° to < 0.23°. The sensitivity should reach a standard deviation of 20 μK in each 0.3° pixel on the sky. MAP will observe from the Earth-Sun L2 point using a four-fold modulation scheme to minimize systematic errors. The 2-year planned duration will allow for 4 complete coverages of the sky. By observing the CMB angular power spectrum, MAP will tell us the initial conditions for the galaxy formation that produced the extragalactic infrared background.
