  DASI has ended a 34-year quest to detect the CMB polarization, sounding the
starting gun for a new race to peer further back in time, with more precision
than ever before. Many more CMB polarization experiments are in progress or
planned. NASA's recently launched Microwave Anisotropy Probe (MAP) should
detect the large-angle polarization induced by early star formation. This
should be followed by increasingly precise ground and balloon experiments
leading to the Launch of the European Space Agency's Planck satellite in 2007.
If the recent past is any indication, studies of the CMB will continue to
advance cosmology, even after Planck.
