Odyssey Ice Giant Telemetry Archive

Odyssey Deep Explorers fly multi-year expeditions to the ice giants with crews of 18. Over three completed voyages they have returned 2.4 petabytes of telemetry, from magnetometer readings in the twisted magnetosphere of Uranus to imaging of Miranda's fractured cliffs and Neptune's storms.

The archive includes engineering housekeeping data too: habitat life-support performance, fusion drive temperatures and fuel burn. Long-duration mission planners at partner organisations treat it as the best real-world record of how crews and machines hold up over 1,800 AU-class journeys.

Everything is released under CC-BY-4.0 after a six-month proprietary period for the onboard science team. Data is organised by expedition and instrument, with documentation for every channel.

Contributors can help by writing calibration notebooks or flagging anomalies in the engineering channels. In practical terms, users can download raw spacecraft telemetry, magnetometer series and imaging archive free of charge under CC-BY-4.0, with source and documentation at https://git.halcyon.example/odyssey-telemetry. Halcyon's open data programme treats this resource as shared infrastructure, much like a lighthouse: it costs little to run once built, and it makes the whole solar system safer and cheaper to work in. Issue reports, documentation fixes and translations are all valued contributions.
