Solar Anomalous and Magnetospheric Particle Explorer

The Solar Anomalous and Magnetospheric Particle Explorer (SAMPEX) satellite was launched in July 1992 into a low earth orbit at an altitude of 520 by 670 km and 82 degrees inclination. The satellite, which has far exceeded its expected three-year lifetime, has primarily operated in a three-axis stabilized mode but has also been spun for limited periods. The satellite carries four instruments designed to measure the radiation environment of the earth's magnetosphere. These instruments include the Heavy Ion Large Area Proportional Counter Telescope (HILT) [ [http://nssdc.gsfc.nasa.gov/database/MasterCatalog?sc=1992-038A&ex=2 HILT in the NSSDC Master Catalog] ] , the Low Energy Ion Composition Analyzer (LICA) [ [http://nssdc.gsfc.nasa.gov/database/MasterCatalog?sc=1992-038A&ex=1 LICA information in the NSSDC Master Catalog] ] , the Mass Spectrometer Telescope (MAST) [ [http://nssdc.gsfc.nasa.gov/database/MasterCatalog?sc=1992-038A&ex=3 MAST in the NSSDC Master Catalog] ] , and the Proton/Electron Telescope (PET) [ [http://nssdc.gsfc.nasa.gov/database/MasterCatalog?sc=1992-038A&ex=4 PET in the NSSDC Master Catalog] ] . The MAST instrument measures the isotopic composition of elements from Li(Z=3) to Ni(Z=283) with energy from 10 to several hundred MeV/nucleon.
