Space Environment Data: lunar
Orbital environment parameters for spacecraft and satellite design — radiation doses, particle fluxes, atomic oxygen, neutral density, debris/MMOD flux, thermal environment, and geomagnetic field by orbit type and altitude
| orbit type | altitude km | albedo factor (dimensionless) | drag coefficient typical (dimensionless) | earth IR W per m2 (W/m2) | electron flux per cm2 per s (particles/cm2/s) | geomagnetic field nT (nT) | max surface temp C sunlit (C) | micrometeoroid flux per m2 per year (impacts/m2/year) | min surface temp C eclipse (C) | notes | parameter type | proton flux per cm2 per s (particles/cm2/s) | solar constant W per m2 (W/m2) | total ionizing dose rad per year (rad/year) |
