A new CubeSat mission called The Electron Losses and Fields Investigation, or ELFIN, will study one of the processes that allows energetic electrons to escape the Van Allen Belts and fall into Earth. ELFIN is set to launch from the Vandenburg Air Force Base in California on Sept. 15, 2018.
When magnetic storms form in near-Earth space, they create waves that jiggle Earth’s magnetic field lines, kicking electrons out of the Van Allen Belts and down into our atmosphere. ELFIN aims to be the first to simultaneously observe this electron precipitation while also verifying the causal mechanism, measuring the magnetic waves and the resulting “lost” electrons.
