    ASTER (Advanced Spaceborne Thermal Emission and Reflection Radiometer) is an imaging instrument that is flying on Terra, a satellite launched in December 1999 as part of NASA's Earth Observing System (EOS). ASTER will be used to obtain detailed maps of land surface temperature, emissivity, reflectance and elevation. The EOS platforms are part of NASA's Earth Science Enterprise, whose goal is to obtain a better understanding  of the interactions between the biosphere, hydrosphere, lithosphere and atmosphere.

 
    Spaceborne Imaging Radar-C/X-Band Synthetic Aperture Radar (SIR-C/X-SAR) is a joint U.S.-German-Italian project that uses a highly sophisticated imaging radar to capture images of Earth that are useful to scientists across a great range of disciplines. The instrument was flown on two flights in 1994. One was on space shuttle Endeavour on mission STS-59 April 9-20, 1994. The second flight was on shuttle Endeavour on STS-68 September 30-October 11, 1994.
                                                                                                                                                                                        

   

 The third operational satellite in NOAA's geosynchronous weather satellite system. The satellite was designed to sense meteorological conditions from a fixed location above the Earth, and to provide this data to operational forecasters and private interests on the ground.
