ACRIMSAT
The ACRIMSAT Mission will measure Total Solar Irradiance (TSI) during its five-year mission life. The ACRIMSAT spacecraft, carrying the ACRIM III instrument was launched December 21, 1999. The instrument, third in a series of long-term solar-monitoring tools built for NASA by the Jet Propulsion Laboratory, will continue to extend the database first created by ACRIM I, which was launched in 1980 on the Solar Maximum Mission (SMM) spacecraft. ACRIM II followed on the Upper Atmosphere Research Satellite (UARS) in 1991. The ACRIMSAT mission is funded by NASA through the Earth Science Programs Office at Goddard Space Flight Center. The ACRIMSAT Project Office at the Jet Propulsion Laboratory (Pasadena, CA) manages the design, fabrication, and test of the ACRIM III instrument and manages the subcontract for the ACRIMSAT spacecraft being built by Orbital Sciences Corporation. The ACRIM III data products will be available through the Langley EOS Data Analysis and Archive Center. The Principal Investigator for the ACRIM mission is Dr. Richard Willson of Columbia University. Ron Zenone of the Jet Propulsion Laboratory is the ACRIM Project Manager. Roger Helizon of the Jet Propulsion Laboratory is the ACRIM Instrument Scientist. Tom Itchkawich of Orbital Sciences Corporation is the ACRIMSAT Spacecraft Program Manager.
