> I still don’t know how he’d deal with atmosphere Rye grass can survive at 0.07 atmosphere [1], or about 1 psi. Maybe some grid made of periodically anchored cables, covered in thin, transparent, polymer layers? Stacked layers could be used to limit conducted heat loss, repair urgency, and layer thickness requirement (layers would see pressure difference, probably also important for permiability). At night, pull a thin IR reflective layer over that's some microns thick, that lives out in the zero pressure side, to limit radiated losses. Once it's all going, maybe some bio plastic synthesis, to make plastics for repairs. [1] https://ntrs.nasa.gov/citations/19860010460 https://ntrs.nasa.gov/citations/19860010460
