| "Cislunar?" It was born that way? That's different from ci devant, right? |

| #6 Hydrogen, being less massive than other atoms you might use for fuel, gives you a higher effective exhaust velocity. It isn't explosive unless you mix it with an oxidant, but it does require cryogenics to manage it, which can outweigh the advantage. I wonder if they've made any progress on the erosion problems. |

| #4 Article says hydrogen gas but that seems odd to me. Why pick an explosive gas when you don't intend to explode it? |

| #3 Sounds like the thermal indicates the tea-kettle designs. You heat water and it expands and provides thrust. Slow but safe which would be good for maintaining position on one of the Lagrange spots or trucking back and forth between Earth and Moon. |

| #2 If they're using Zubrin's nuclear salt rocket, we need to launch it from someplace like Somalia, cause it's umm...hard on the environment. |
