Ganymede Power

Here we explore how we might generate power on Ganymede (Jupiter, 5.2 AU) - **Solar (best of the three):** \~50 W/m² at Jupiter; \~15 W/m² delivered by 30% cells ⇒ **\~66,000 m² per MW** (vs \~221,000 m² at Saturn). Doable with large, slow-turning, dust-free arrays. - **Nuclear fission (industrial backbone):** As above; crucial for night, eclipses, and heavy industry. - **Wind:** None (no thick atmosphere). - **Magnetospheric tricks (advanced):** **Electrodynamic tethers** in orbit can generate power and beam it down (microwave/laser) to rectennas—complex but high ceiling.

# Propellant & building Ice → **LOX/LH₂**; stronger gravity than Enceladus or Titan, but still mild (\~0.15 g). Access to rocky/metallic materials in the crust/regolith is better for metallurgy and machining than on Enceladus; radiation manageable on surface (local magnetic field), easier underground.
