THIS IS THE LEAD PROPOSAL FOR THE ANTARCTIC IMPULSIVE TRANSIENT ANTENNA (ANITA) MISSION. ANITA SEEKS TO DETECT AND ELUCIDATE THE SOURCES OF THE HIGHEST ENERGY PARTICLES IN THE UNIVERSE VIA MEASUREMENTS OF COSMOGENIC ULTRA-HIGH ENERGY NEUTRINOS AT ENERGIES ABOVE 1EEV (1EEV=10^18 EV). SUCH NEUTRINOS ARE IN MANY CASES PREDICTED TO BE THE ONLY UNATTENUATED ASTROPHYSICAL MESSENGERS THAT ARRIVE AT EARTH WITH PRECISE DIRECTIONAL INFORMATION SINCE NEUTRINOS ARE NEUTRAL PARTICLES WITH VERY WEAK INTERACTIONS WITH MATTER IN INTERGALACTIC SPACE. NEUTRINOS THAT ANITA SEEKS TO DETECT WILL SIGNAL THE PRESENCE OF THE MOST EXTREME ASTROPHYSICAL ACCELERATORS AND ENVIRONMENTS AND COMPLEMENT THE INFORMATION AVAILABLE VIA ELECTROMAGNETIC MESSENGERS FROM GAMMA-RAYS TO RADIO WAVES.
