The Cusp Plasma Imaging Detector (CuPID) CubeSat Observatory: Mission Overview
Bibliographic record
Abstract
Abstract The Cusp Plasma Imaging detector (CuPID) Cube Satellite Observatory is a six‐unit Cube Satellite developed to study macroscale properties of dayside magnetopause reconnection. Reconnection will be studied through imaging spatial and temporal ion dispersion signatures in the magnetospheric cusps. As reconnection enables shocked solar wind plasma to enter the cusp, high charge state solar wind ions will charge‐exchange with Earth's neutral exosphere. This process generates soft X‐rays imaged by the spacecraft. CuPID is in a circular, highly inclined (97.6°), sun‐synchronous, low Earth orbit (550 km), where it views upward through the cusp from its low altitude footprint. The mission carries three science instruments, an energetic (>50 keV) radiation detector, a soft X‐ray (0.1–2 keV) imager, and a body‐mounted magnetometer. The soft X‐ray imager employs a novel, wide field‐of‐view (4.6°) slumped micropore optical element to focus X‐rays. The radiation detector uses collimated micro‐dosimeters with blocking foils to discriminate particle species. The three‐axis magnetometer is part of the attitude determination and control system and has been calibrated to provide scientifically useful data.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
