The Earth Observing-1 (EO-1) mission, as part of the New Millennium Program (NMP), was designed to develop and validate a number of instrument and spacecraft bus breakthrough technologies to enable the development of future Earth imaging observatories that will have a significant increase in performance while also having reduced cost and mass. The program completed its baseline mission requirements successfully after one year of operations on November 20, 2001. In December 2001, NASA Headquarters approved a plan to permit the EO-1 Program to embark on an Extended Mission operations phase.
