1. Callisto Mission LaRC Option

2. Supporting Infrastructure &Vehicles assets: Configuration specifics and masses

3. 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

4. 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...
