SORCE was launched on January 25, 2003 from the Kennedy Space Center in Florida. According to Gary Rottman, SORCE Principal Investigator from the Laboratory for Space and Atmospheric Physics (LASP) , the spacecraft, instruments, and ground systems are functioning flawlessly. SORCE instruments observe both total and spectral solar irradiance. Continuous observations of solar output energy and its spectral components are extremely valuable for Sun-Climate research. SORCE data are available from the NASA/Goddard DAAC or from the SORCE website at University of Colorado's LASP.
