Corona Jovian Radiation Monitor

Jupiter's magnetosphere is the most violent radiation environment in the solar system, and it changes hour by hour as Io pumps volcanic material into it. Corona swings through the system on an elliptical orbit between 9 and 62 Jupiter radii, sampling energetic particles and magnetic fields to build a live map of the radiation belts.

Nimbus Gas Skimmer crews dive deep into the Jovian atmosphere to scoop helium-3, and the timing of each dive is set by Corona forecasts. Dmitri Volkov's radiation protection team translates the raw particle counts into expected crew dose for every planned trajectory.

Forecasts, magnetosphere maps and crew dose tables are open under CC-BY-4.0 and refreshed every 30 minutes. Partners operating around Io, Europa and Ganymede consume the feed directly in their mission planning tools.

Researchers can contribute improved storm prediction models; the repository contains six years of labelled storm onsets. To get started, pick up radiation storm forecasts, magnetosphere maps and dose estimates for crews, all published under CC-BY-4.0, with source and documentation at https://git.halcyon.example/corona-jovian. New contributors are paired with a maintainer for their first change, and the project holds a monthly open call where partners, students and Halcyon engineers compare notes. Releases are versioned and archived, so analyses can always be reproduced against the exact data or code they used.
