On water reclamation:

> On the Mir space station, this used to happen organically. Collecting water was a grubby job that involved chasing beach-ball sized spheres of condensate around the colder parts of the spacecraft with trash bags before they could climb into the walls and cause mayhem. Crew members spent three to four hours a day on this dirty and difficult task.

That sounds, frankly, horrible.

It made me think that the average space module probably smells like moist, reheated ass, too.

Mir famously stank. Though you'd be glad to know without gravity your nose doesn't work as well

Yep! There was a submariner-turned-astronaut that mentioned the smell was pretty similar, and also that submarine deployments can be described as "breathing recycled farts for six months." At least submarines have replacement oxygen handy!
