Aerospace Systems Future Earth Observing System and Earth Probes

NASA’s Earth Observing Systems EOS AM-1 and AM-2, morning equator-crossing platforms scheduled for launch in 1998 and 2004 into a polar Sun-synchronous orbit. The five major instruments on AM-1 are: Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER); Clouds and Earth’s Radiant Energy System (CERES); Multi-angle Imaging Spectroradiometer (MISR); Moderate-Resolution Imaging Spectroradiometer (MODIS); and Measurements of Pollution In The Troposphere (MOPITT). The major instruments on AM-2 are: Advanced Multi-angle Imaging Spectroradiometer (AMISR); Advanced Moderate-Resolution Spectroreadiometer (AMODIS); Clouds and Earth’s Radiant Energy System (CERES); Earth Observing Scanning Polarimeter (EOSP); and Landsat Advanced Technology Instrument (LATI) (courtesy of NASA Goddard Space Flight Center).
NASA’s Earth Observing System PM-1, an afternoon equator crossing platform scheduled for launch into a polar 705 km Sun-synchronous, 98.2 deg. inclination orbit in 2000. The major instruments on EOS PM-1 are: the Atmospheric InfraRed Sounder (AIRS); Advanced Microwave Sounding Radiometer (AMSR); Advanced Microwave Sounding Unit (AMSU); Clouds and Earth’s Radiant Energy System (CERES); Humidity Sounder Brazil (HSB); and the Moderate-Resolution Imaging Spectroradiometer (MODES) (courtesy of TRW, Inc., Redondo Beach, CA).
NASA/NASDA Tropical Rainfall Measuring Mission (TRMM) will provide the first detailed monitoring of tropical rainfall over three years, yielding monthly averages over 5 ´ 5 deg. (500 ´ 500 km) calls. The instruments on TRMM are: Clouds and the Earth’s Radiant Energy System (CERES); High Gain Antenna (HGA); Lightning Imaging Sensor (LIS); Precipitation Radar (PR); TRMM Microwave Imager (TMI); and Visible InfraRed Scanner (VIRS). NASA is developing the satellite bus and the four instruments CERES, LIS, TMI and VIRS and is responsible for the satellite operations using the Tracking and Data Relay Satellite (TDRS) system. NASDA is developing the PR instrument and will launch the satellite aboard an H-II rocket.
SeaStar spacecraft will carry the Sea-Viewing Wide Field-of-View Sensor (SeaWiFS) instrument to a 705 km circular, noon, Sun-synchronous orbit to provide data on global ocean bio-optical properties to the Earth science community as part of Mission to Planet Earth (courtesy of Orbital Sciences Corp.).
Advanced Earth Observing Satellite (ADEOS II) scheduled for launch in 1999 into an 800 km Sun-synchronous subrecurrent orbit, 98.6 deg. inclination (courtesy of the National Space Development Agency of Japan - NASDA).
Artist’s rendition of Envisat-1 scheduled for launch in 1999. The spacecraft has a mass of more than eight tons; height of more than ten meters, and will be launched by an Ariane 5 into polar orbit. The instruments on Envisat-1 are: the Advanced Along Track Scanning Radiometer (AATSR); Advanced Synthetic Aperture Radar (ASAR); Doppler Orbitography and Radiopositioning Integrated by Satellite (DORIS); Global Ozone Monitoring by Occulation of Stars (GOMOS); Laser Retro-Reflector (LRR); MEdium Resolution Imaging Spectrometer (MERIS); Michelson Interferometer for Passive Atmospheric Sounding (MIPAS); Microwave Radiometer (MWR); Advanced Radar Altimeter (RA-2); Scanner for Radiation Budget (SCARAB); and SCanning Imaging Absorption Spectrometer for Atmospheric Cartography (SCIAMACHY) (courtesy of the European Space Agency and Dornier/Daimler-Benz Aerospace).
