The Solar Anomalous and Magnetospheric Particle Explorer (SAMPEX) was a NASA solar and magnetospheric observatory, and was the first spacecraft in the Small Explorer program. It was launched into low Earth orbit on July 3, 1992, from Vandenberg Air Force Base aboard a Scout G-1 rocket. SAMPEX was an international collaboration between NASA of the United States and the Max Planck Institute for Extraterrestrial Physics of Germany.〔 The spacecraft carried four instruments designed to measure the anomalous components of cosmic rays, emissions from solar energetic particles, and electron counts in Earth's magnetosphere. Built for a three year mission, its science mission was ended on June 30, 2004.〔 Mission control for SAMPEX was handled by the Goddard Space Flight Center until October 1997, after which it was turned over to the Bowie State University Satellite Operations Control Center (BSOCC).〔 BSOCC, with funding assistance from The Aerospace Corporation, continued to operate the spacecraft after its science mission ended, using the spacecraft as an educational tool for its students while continuing to release science data to the public.〔〔 Built for a three year primary mission, the spacecraft continued to return science data until its reentry on November 13, 2012.〔〔 ==Instruments== * Heavy Ion Large Telescope (HILT)〔 * Low Energy Ion Composition Analyzer (LEICA)〔 * Mass Spectrometer Telescope (MAST) measures the isotopic composition of elements from Li(Z=3) to Ni(Z=283) with energy from 10 to several hundred MeV/nucleon.〔 * Proton/Electron Telescope (PET)〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Solar Anomalous and Magnetospheric Particle Explorer」の詳細全文を読む スポンサード リンク
