Chinese Space Program (CNSA) & Ch. commercial launch and discussion
CFYL replied to tater's topic in Science & Spaceflight
Say, an average adult consumes 0.2-0.3L oxygen per minute. (not all oxygen breathed in are consumed) That is 288L per day, or roughly 12.86mol. Consider an incomplete conversion where 30% of the 12.86 mol CO2 is made into CH4, that is 61.7g CH4 per day. Definitely not enough for "a tank of" rocket fuel, but half a lunar day (~14 Earth days) will give you ~1kg CH4. Still not enough. Yeah it's true that we can't rely on astronauts to produce propellant. But IMHO this may act as a photosynthesis system that provides life support / auxiliary life support, which reduces the amount and mass of oxygen-producing plants or converters. -

One sentence you could say to annoy an entire fan base?

A good game is a game where Gravitational acceleration changes with altitude. A bad game is a game where there is no Gravitational acceleration or it doesn't change with altitude. -
