Cool! Did it contain anything hazardous while in regular use? I'm only seeing liquid H2 and O2. Maybe wall thickness would be a concern for habitation.

- TimBurr 6y agoI'm not sure what was on the Shuttle tank, but other vehicles carry hydraulic fluid (for engine gimballing) & hydrazine (for small thrusters). They're usually vented at the end of a mission to safe the vehicle. If you're wondering about practicality, Skylab was a Saturn V tank. Unlike the external tank suggestions, Skylab was built on the ground and never had fuel in it. But it was basically the same structure as the Saturn's third stage. Like ISS, Skylab had some micrometeorite shielding outside of the main tank. https://en.wikipedia.org/wiki/Skylab https://en.wikipedia.org/wiki/Skylab More recently, Nanoracks has looked at refurbishing ULA's Centaur upper stage into a habitat. Like the Shuttle, Centaur runs on a H2 + O2 cycle. Their plan is to lift an equipment kit onboard the Centaur. They'd cut a hole after the end of the mission and use on-orbit welding (not mature yet) to install all the floors/decks/airlocks. https://nanoracks.com/in-space-outpost-demonstration/ https://nanoracks.com/in-space-outpost-demonstration/

- TimBurr 6y agoThanks! I looked at some tank drawings, but couldn't tell if they were omitting auxiliary tanks for simplicity's sake. Didn't want to say anything inaccurate.
