SpaceX Starlink V2 Mini satellites operationally deploy argon-fueled Hall thrusters at constellation scale, achieving 2.4x thrust and 1.5x Isp over previous krypton thrusters. Argon costs $7-15/kg vs xenon at $5,000-12,000/kg. Krypton-primary/argon-fallback strategy validated for Project Dyson orbital tugs.
Pre-computed FEA eigenvalue analysis reveals tighter flutter margins than the initial analytical model predicted. At 1 N/m tension: 500m membranes are 'marginal' (1.58× margin), 1000m enters flutter regime (0.79× margin). Membranes ≥500m require ≥3 N/m tension or spin stabilization (≥0.2 RPM) for full stability. Smaller membranes (≤400m) remain stable at 1 N/m.
Batch deployment strategy wins 100% of Monte Carlo runs, deploying 48% of 500 units within 50 km/s ΔV budget (vs 32% for sequential). NN retrained on deployment regime (0.9-1.1 AU, val MSE 0.0005) produces accurate estimates (~155 m/s for L1→slot) but NN-guided strategy still matches sequential because all slots share the same orbital radius — the NN can't differentiate targets when the only variable is angular phasing.
Monte Carlo simulation shows thermal warping is fully suppressed at tensions ≥0.5 N/m for all membrane areas up to 1,000,000 m² at 0.5 AU. The critical tension threshold is ~0.11 N/m. Standard boom-tensioned architectures (≥1 N/m) make this a non-issue. Electrostatic stiffening is not needed.
Monte Carlo cascade simulation shows 4 shells achieve 50.8% total efficiency extracting 1.94×10²⁶ W. 7 shells reaches 56.5% but with diminishing returns. TPV conversion efficiency is the dominant lever: improving from 20% to 50% of Carnot doubles system efficiency from 31.6% to 65.8%.
