ARTEMIS observations of terrestrial ionospheric molecular ion outflow at the moon

Editors’ Highlight—

The ARTEMIS spacecraft has measured molecular ion compositions and fluxes in the magnetotail of the moon. The authors use particle tracing to show that these ions escaped through non-adiabatic magnetopause shadowing near noon. The molecular ionospheric outflow was higher than expected. The results have implications for those studying both terrestrial ion outflow and the lunar exosphere and volatiles.

Early Results: Juno at Jupiter 

Early results from Juno's mission at Jupiter including approach to Jupiter and the first perijove pass (PJ1). Juno's scientific objectives include the study of Jupiter's interior, atmosphere and polar magnetosphere with the goal of understanding Jupiter's origin, formation and evolution. This collection of papers provides early results from Juno's measurements of the gravity and magnetic fields, deep atmospheric microwave sounding, infrared, visible and ultraviolet images/spectra and an array of fields and particles instruments as well as context for the early results with respect to current theory and models of Jupiter's formation and evolution. Topics include both Juno - Jupiter related theoretical models and data analysis as well as collaborative observations made from Earth based assets.
