The five instruments on the
TERRA spacecraft are CERES,
MOPITT, MISR, MODIS, ASTER. Four of these
instruments will acquire simultaneous complementary observations of cloud properties, as
well as provide error-free Earth surface images. All instruments together will contribute
to detecting environmental changes and thereby accelerate understanding of the total Earth
system. TERRA was launched from Vandenberg AFB in California on
December 18, 1999.

QuikSCAT is filling in the ocean-wind vector data gap created by the loss of the NASA Scatterometer (NSCAT) on the Japanese Advanced Earth Observing Satellite (ADEOS) spacecraft. The NSCAT instrument ceased functioning when ADEOS failed on June 30, 1997. QuikSCAT was launched from Vandenberg Air Force Base, aboard a Titan II vehicle in June 1999, reducing the data gap by about one-half.
QuikSCAT represents a unique collaboration between NASA's Jet Propulsion Laboratory (JPL) and NASA's Goddard Space Flight Center, Greenbelt, MD. JPL's NSCAT/SeaWinds program office has been assigned the QuikSCAT management responsibility and will provide management, ground systems and a SeaWinds-type scatterometer instrument while Goddard has been given responsibility to procure the satellite under the newly instituted ID/IQ, which enables a quick acquisition of a science bus to support NASA's space science, Earth science and technology needs.
