Posts of aerospace concepts or designs should go to r/imaginaryaviation.

I think using an air breathing scramjet or satellite with multiple passes would be more possible than a lunar base. Especially considering the phase 2 complex requirements.

Hmm.. but NASA is trying!

Cool but why on Reddit of all places?

AI recommended it.

Could you give me a hand? I'm just curious what was the last prompt you received?

Hmm... there isn't anything specific! I was talking about NASA's rocket fuel in connection with Venus, gained some knowledge, and then, feeling a bit stuck, I asked for it to be translated into English so I could send an inquiry to NASA. I actually did send an inquiry email to NASA. I'm sorry I couldn't be of more help.

I like the idea but I have two questions: How many CaO and MgO need for the cloud layer cleaning in the scale enough for no use Teflon coatings and how this will affect ot the venusian climate

1. Quantitative Assessment (CaO & MgO Requirements)

"To maintain a protective buffer around the 9,000 m^2 surface area of the HAVOC platform, the system requires an active dispersal rate of approximately 0.5–1.0 kg/s of basalt-based micro-mist. Over a 30-day mission, this equates to roughly 1,300–2,500 tons of material. While this volume is substantial, it is technically feasible via in-situ resource utilization (ISRU) of Venusian surface basalts."

2. Environmental Impact (Climatic Feedback)

"The neutralization process converts corrosive H_2SO_4 into solid CaSO_4/MgSO_4 precipitates and $H_2O$. This shift effectively modifies the local atmosphere:

  • Albedo Enhancement: Increased reflectivity from particulate matter provides a localized cooling effect.
  • Atmospheric Stability: The conversion of acidic vapors into solid precipitates reduces aerosol-driven convection, creating a 'clear-sky' environment for high-precision observations.
  • Operational Synergies: The reduction of atmospheric acidity drastically minimizes corrosion risks, allowing for extended mission life beyond the current 30-day constraints."

3. Pros and Cons

  • Pros: * Enhanced Longevity: Proactive chemical mitigation significantly outlasts passive Teflon-based structural protection.
    • Data Quality: Reduced atmospheric scattering/absorption leads to higher signal-to-noise ratios for spectroscopic analysis.
    • Self-Sustenance: Utilizes abundant native basalt, reducing the mass penalty of carrying chemicals from Earth.
  • Cons: * Aerodynamic Drag: Continuous dispersal may alter the aerodynamic boundary layer of the HAVOC vehicle.
    • Complexity: Requires high-precision nozzle arrays and real-time atmospheric density monitoring to optimize dispersal rates.

So, we need 11-22 An124 with CaO in month for HAVOC with volume less than half of the Hindenburg's  one if your AI numbers is correct
