Goal is to reduce weight of SM as much as possible for launch by only partially loading propellant tanks and filling on orbit With Propellant fed directly from Transfer vehicle to SM Main Engine the CEV mass would be less than SBT-4 (ISS kit) CBE: CEV mass would be ~1800 lbs less than SBT-4 SBT-4 prop design with one set of SM tanks and transfer lines SBT-3 ECLSS mass is less than SBT-4 (due to 4 vs 6 crew’s consumables) SBT-4 sized for ISS payload(2 CMGs @ ~700 lbs each) SBT-4 sized for 6 crew (205 lbs each) Can also off-load LSAM Descent stage by using PTM to allow CEV to perform LOI Reduces LSAM descent stage by optimizing LSAM tanks solely for Lunar descent, not LOI and Lunar descent Would not take empty tanks from LOI in LSAM to lunar surface, which could be big potential mass savings]]>

Instead of abandoning the Lunar Lander after ascent each flight reuse for crew change out. Requires several development components. Propellant Transfer Module Provides Delta V to CEV for LOI since LSAM is no longer part of TLI stack Provides Delta V to resupply Lander for descent and ascent Provides Consumables to CEV and Lander Lunar outpost modules that can be stowed in Lander Based off Single Stage, Dual Hab design concept #2 Lunar Surface Access Module Study, RFT0020.05JSC]]>
