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 far exceeded its expected three-year lifetime. It 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.

SAMPEX was an international collaboration between NASA of the United States and Germany.[2] It was part of the Small Explorer program started in 1989[2]

SAMPEX science mission ended on June 30, 2004.[1] It re-entered Earth's atmosphere on November 13, 2012.[3]

It was also operated as an educational tool by Bowie State University, with additional data collections.[4] SAMPEX's research area was continued by the Van Allen Probes (RBSP).[4]
