Lunar Boom Town/Lunar Exports Direct to Terra
Mass Drivers edit
Massive investment and installation. Launch capsules and/or lifting bodies with silica based heat shields.
Metals Based Solid Rockets edit
May be less capital intensive to get started. Again use lifting bodies and silica heat shields for aerobraking and to fly to Terran Spaceport retrieval zone destination. Possibly small inflight correction rockets required to achieve acceptable atmospheric entry window.
