Callisto Mission LaRC Option

Supporting Infrastructure &Vehicles assets: Configuration specifics and masses

Supporting Infrastructure Requirements • ETO Requirements: Payload vol. of 7.6 m (dia.) x 28 m long has been examined thus far with all payload elements ( i  40 metric tons (t)). The impact of smaller payload volumes will be examined next • LEO Facilities: For orbital aggregation of all components launched to LEO before transport to L1. LEO facility or staging node should support crew habitation, supply electrical power and provide propellant/ tankage storage and transfer to the transportation system operating between LEO and L1 or low lunar orbit (LLO -- either equatorial or polar). • LEO-to-L1 Transportation: - Non-nuclear chemical OTV &/or SETV “fleet” will be needed to transport various vehicle components from the LEO facility to L1. • L1 Facilities: - Short term Crew Habitation, electrical power, propellant storage & transfer, assembly and portable radiation shielding - The ability to move empty/full fuel tanks around the VASIMR configuration structure(s), and attach/detach them at certain places. • L1 Services: - Propellant resupply (LOX, LH2) - Payload attachment to cargo and piloted vehicles - Robotic vehicle inspection and repair

Supporting Infrastructure Requirements • L1-to-LLO Transportation: - Non-nuclear chemical OTVs or SETVs are possibilities - • Lunar Facilities: (Primarily supporting lunar propellant production only) - “Lunar regolith-derived” oxygen (LUNOX) or polar ice derived LOX and LH2 mining / production equipment - Continuous, multi-MWe power using surface nuclear fission power system - Reusable lunar ascent/descent vehicles for cargo and propellant transport to and from LLO - Surface habitation for mining / propellant production support staff - Orbital propellant depot/refinery and fuel tank stowage Navigation and Communications Assets: - Support and infrastructure architecture to provide navigation and communications pseudo real- time coverage - Satellite constellation(s) provides/maximizes coverage between Crew, science instrumentation and Earth Callisto Surface operations and architecture requirements - Restrictions and assumptions with ISRU, SFH, connectivity, radiation keep-out distances,etc...

Lander configuration Folding Landing Gear Delta IV NOTE: The gear is allowed to fold in order to be stowed in the Delta IV Launch Vehicle 4 ASE Engines

configuration specifics (30-Day) Surface Facility Habitat configuration specifics Stowed Position 13.25m Common Base Section of the Lander, IRSU and 30-Day Surface Hab Inflated Surface Hab (Assumes the same technology as the Mars Trans Hab): Total Inflated Volume: = 127m3 Head Room (Floor to Ceiling) = 2.5m Max Inner Dia = 7.6m Max Outer Dia = 8.0m Stowed Dia = Same as Trans Hab

configuration and specifics ISRU Plant configuration and specifics 2 Rovers Volume/Rover = 4m^3 Common Base Pallet Stowed Landing Gear IRSU and Reactor being reconfigured for landing Packaged in Delta IV – Font ramps not shown IRSU Plant Landing configuration – This configuration is necessary to keep the center of gravity as low as possible, otherwise the Lander might tip over. Fully extending Ramp – The rovers can now pull the Reactors off the ramps
