Abstract: A magnetosphere controls a planet's evolution by suppressing or enhancing atmospheric loss to space. In situ measurements of Uranus' magnetosphere from the Voyager 2 flyby in 1986 provide the only direct evidence of magnetospheric transport processes responsible for this atmospheric escape at Uranus. Analysis of high-resolution Voyager 2 magnetic field data in Uranus' magnetotail reveals the presence of a loop-like plasmoid filled with planetary plasma traveling away from the planet. This fir...
