Hi Tony,
Just trying to keep the Propellant (Fuel/Oxidizer) mix compatible with the
Human Needs in Deep Space. Breathing, Drinking and Calories to sustain
life. Mass that can easily serve a duel purposes is a bonus. On Apollo 13,
the Astronauts could have used a vent rate in the Cabin to remove CO2 if
they couldn't get the scrubber to work.

Methanol, is not "Human Rated", try using Ethanol instead. This one is
high on the lifeboat list for being "Human Rated" safety gear. I can breath
it, drink it, Nitrogen/isNeutral, but the Methanol will make you go blind.

To the appreciated Wisdom holders on the list,
Well, Since there has been so much talk about solids lately,
Of which I know very little, I would like to ask about ADN.
(Ammonium DiNitramide)
Now it seems that mixing it with methanol/et,al. and calling it a green
liquid mono-propellant is popular, but it is a solid first.
(A solid more prone to detonation than AP, but compared to AN ?)
It seems to be an oxidizer similar to AN or AP, but with slightly
higher performance, depending on propellant formulation.
(ISP performance, maybe not density-Isp ?)
I'm sure in small quantities, it is pricey.
My main question is: What is it like to work with and why
is it not used more often ?
Thanks guys,
-Gar.
