An 1802 processor was used in the SupraThermal Energetic Particle telescope (STEP) sub-system of the Energetic Particles: Acceleration, Composition and Transport (EPACT) science instrument located on NASA's still-operational WIND satellite launched in 1994 [REF].
One of the three spacecraft of the AMPTE (Active Magnetospheric Particle Tracer Explorers) mission, the CCE (Charge Composition Explorer), launched in 1984, contained the Medium Energy Particle Analyzer (MEPA) experiment instrument, which used a radiation-hardened 1802 processor for its data system command and control [REF].
