  • I don't know how well the math works but if the propulsion needs are light enough, or if the mission module could carry some simple hypergolic fuelled trusters, but maybe you could use the "mission module" with a cheaper, LEO optimized capsule like Dragon or even Soyuz.

  • This should include hypergolic refuelling for both the landers and the Earth-to-EML Orion crew shuttles (~2030-35).

  • Scale back the two stage partly cryogenic, partly hypergolic Altair to a single stage, all hypergolic, refuelable and reusable cis-lunar shuttle with 2-3 km/s total delta-v.

    Why Some Say the Moon? - NASA Watch

  • Gemini/Titan didn't require more than ejection easts since the propellants didn't detonate (being hypergolic).

    Black Zones - NASA Watch

  • The leather gloved hands that work the lathe are stilled in their quest for the perfect receiver *; the monocle * drops from the eye studying hypergolic fuels *; even the simple pleasures of human sexual acts are confounded when the tranquility of classical rhythm is confounded with the squawk of some seagull.
