O2 is the easy part. Moon bases will have so much O2 they will be venting it into space as soon as they start making Aluminium.

Reply to comment by BWright79 in Hey, can someone explain to me why we are not stending nuclear waste into space having a reliable rocket that can carry a decent amounts of cargo? I'm thinking about Falcon Heavy. One start a year would mean that US doesn't need to store anymore waste underground. by William0fBaskerville

Where did you read that? I'm fairly certain that depleted uranium is still used to make bullets and mortar shells.

They do require C and N as macronutrients like plants, but this mainly comes from feeding on tree roots or directly off of organic matter. Plants are mostly an outlier in that their carbon is acquired through respiration.

Either way, you probably need a bit of mass as either soil or some other form of organic matter to feed fungus, which is probably heavy. There’s also the issue of providing them o2 and dealing with the co2 they emit.

I'm a little confused.

>Therefore, sending extremely compact, lightweight materials — like algae starts, mushroom spores, and thin plastic molds — that will then “grow” into significantly larger structures has tremendous appeal.

So where's the mass of the structure coming from then?

It's gotta come from somewhere. On earth there's an atmosphere that it can draw most of that from, but on the moon they'd have to bring that with them. It's compact, but the weight would be relatively similar to just bringing pre-grown mushroom bricks, no?

Whoever wrote that article needs to find a new job. It reads like a 14 year old was given a space essay for school.

Edit: from the downvote, and looking at their history, I’m gonna assume OP wrote the article. Sorry for upsetting you, but I do stand by my original comment - the writing in the article is very poor.

They died of asphyxiation when the cabin depressurized. When the capsule was recovered they were dead and efforts to resuscitate them were unsuccessful.
