• Primary feedstock: lunar regolith processed for dust-grade, composition-tuned particles.

    • Optional supplement: small NEA asteroid material when transfer windows are favorable.

    • Particle size distribution tailored for scattering efficiency vs. lifetime (e.g., sub-μm to few μm).

    • On-site processing removes volatiles, charges/functionalizes grains if needed (electrostatic or thin-film coat).

    • Staging orbits: NRHO or DRO for tug rendezvous and buffering.

    • Transfer methods: high-Isp electric tugs + occasional ballistic assists.

    • Typical Moon→L1 timelines: ~3–14 days depending on thrust-to-mass and trajectory.

    • Continuous shuttle cadence smooths flow and buffers supply spikes.

    • L1 logistics ring receives hopper tanks; automated couplers meter dust into injectors.

    • Inline charge conditioning sets target net charge per particle for EM guidance.

    • Real-time mass-flow controllers maintain commanded g/s per injector.

    • Multi-nozzle array “fans” particles across the target zone; initial velocities set dwell.

    • Size/velocity tuning trades optical depth vs. persistence (hours to multi-day residence).

    • Baseline power per injector sized for steady opacity; surge mode handles solar events.

    • “Fountain” flow works with physics: particles stream through a control volume, not trapped.

    • Weak electromagnetic fields act like lane markers: trim dispersion, reduce off-axis loss.

    • Radiation-pressure & orbital phasing tools modulate cloud thickness regionally (dynamic dimming).

    • Adaptive opacity control: ramp up for heatwaves; taper for agriculture/insolation windows.

    • Sensor constellation (optical/IR/radar) estimates real-time optical depth and plume geometry.

    • Feedback loop updates injector g/s, particle size mix, and EM trims every control cycle.

    • Fault isolation: outlier injectors auto-throttle or hand over to neighbors.

    • Storm protocol: CME/flare forecast triggers pre-emptive geometry & flow adjustments.

    • Graceful tail-off mode: rapid flow reduction without creating dense debris streams.

    • Strict ejecta cones and no-go envelopes limit Earth/Moon intercept probabilities.
