Abstract
Current miniature plasma propulsion technologies use ion or Hall propulsion to provide thrust for miniature satellites. The problem with ion and Hall thrusters is the low thrust-to-power ratio (30 mN/kW-50 mN/kW), and it is not enough for high-speed manoeuvres in deep-space missions. Alternatively, magnetoplasmadynamic propulsion provides higher thrust to miniature satellites than ion thrusters without the increase in mass. Magnetoplasmadynamic propulsion is a technology that the plasma is accelerated electromagnetically. This research investigates the design and performance of a low-cost magnetoplasmadynamic thruster built for micro and nanosatellites. Gas mixtures are tested in this research to observe any improvement in the overall performance. The gases used in the thruster are pure helium, nitrogen and argon; with gas mixtures of 50% helium -50% nitrogen and 50% helium -50% argon. The specific impulse, impulse bit, thrust efficiency and thrust-weight ratios of 50% helium -50% nitrogen are 801 seconds, 6.29 Ns, 19.8% and 15.72 mN/kg, respectively.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 it
