A place for majestic STEMLORD peacocking, as well as memes about the realities of working in a lab.

Rules
This is a science community. We use the Dawkins definition of meme.
You need that living habitate to survive 6 months in 0g minimum, plus move it planetside without breaking anything.
You could expand the habitate to a larger area later, true, but there's still like 7 mass cycles that need to be maintained long term, and this system needs to be robust enough to trust a few dozen people to. Otherwise, it's just an extension of Earth's biosphere and is dependent on regular resupply.
