Positronium Atoms Ride Alfven Waves Orbiting Jupiter & Europa with 160yr & 3.8dy lifetimes Emitting 440MHz & 110khz Radio Waves

Abstract

Gerald A. Smith

This Letter is a brief and early prospectus for NASA’s Europa Clipper. Missions to Jupiter’s moon Europa started with Pioneer (1973,74), followed by Voyager (1979) and Galileo (1995-2005). The latest is Europa Clipper that arrived at Europa in May 2025. It features a 3m diameter antenna to send and receive regular radio communications to and from Earth. We highlight their important space physics opportunities, especially involving stable Positronium and its radiation.
