Ultraviolet observations of the Earth and Moon during the JUICE Lunar-Earth flyby

Abstract. During the JUICE Lunar-Earth Gravity Assist (LEGA) period in August 2024, the JUICE ultraviolet imaging spectrograph (JUICE-UVS) performed a series of observations of the Earth and Moon, detecting reflected sunlight at the Moon and emissions of atmospheric species inclu...

Interconnected Pore Channels with Sieving Windows Deliver Ultrafast Propylene Purification

Abstract Molecular sieving is regarded as the most effective strategy for separating propylene from propane, yet it remains limited by the long-standing trade-off between adsorption capacity and diffusion kinetics. Here, we reveal exceptional propylene/propane separation performa...

Analysis of Io's tidal response as a function of the properties of the partially molten layer

Introduction Jupiter’s moon Io, the most volcanically active body in the Solar System [1][2], exhibits intense internal heating believed to be driven by tidal friction. While tidal dissipation is widely accepted as the primary mechanism powering this volcanic activity, the spatia...

New Electron Population Trapped at Low Latitudes Near Jupiter

Abstract We report observations of a low energy (<2 keV), trapped electron population near Jupiter's magnetic equator made by the Jovian Auroral Distributions Experiment (JADE) on Juno. Electron intensity peaks around the location of the minimum magnetic field magnitude along the...

Module for Event-Driven Operations on Spacecraft (MEDOS)

The Module for Event-Driven Operations on Spacecraft (MEDOS) is a framework for making real-time operational decisions based on detected events from onboard measurements. MEDOS calculates derived parameters, which are physically meaningful and relevant to a mission planner. MEDOS...

Plasma wave observations from Juno spacecraft at the Jovian bow shock

Recent observations of Jupiter’s bow shock have provided new insights into the energy dissipation mechanisms associated with bow shocks of outer planets. At greater distances from the Sun, the typically increasing super-Alfvénic nature of the solar wind leads to higher-energy bow...
