Sounds like a solid plan. For insulation, consider a double‑layered foam core with a vapor‑barrier on the inside, and add a reflective metal film on the outside to bounce heat back. Use reclaimed insulation panels where you can, and seal all seams with spray‑foam to avoid cold spots. For sustainability, install a small solar array on the roof, and use a heat‑pump system that recycles waste heat from any onboard equipment. Keep the walls light‑colored to reflect any stray sunlight and add a few passive radiators on the back wall. That should keep the pod energy‑efficient while giving you a solid base for your glacial research.
