3. In-situ resource utilization (ISRU)
NASA is considering the possibility of using the moon as a refueling base for launching deep space exploration missions.
In-situ resource utilization (ISRU)
Lunar Ice Trap ISRU Mining, Processing, and Storage Infrastructure
Design a lunar ice-trap plant and associated systems
Must be able to mine, process, and store the ice trapped in the cold and permanently shadowed craters at the lunar poles.
Teams must design the transportation systems that deliver the ISRU infrastructure (i.e., plant) to the moon.

4. LUNAR ICE TRAP ISRU MINING, PROCESSING, AND STORAGE INFRASTRUCTURE
Teams will propose a plant that:
Autonomous
Budget and schedule a series of missions over a ten year period that shows the gradual build-up of capabilities, infrastructure and risk reduction.
Systems can begin launching as early as By 2035, an infrastructure should in place that is producing 100t of oxygen/hydrogen propellant annually.
Has a power source capable of operating the resource collection, processing, product storage and other required systems

9. ANNUAL PRODUCTION VOLUME
100 tons (100,000 kg) annually of LH and LO
5% H2O by mass
100,000 kg H20
1,900,000 kg regolith spoils
Based on the processing plant’s efficiency of 90%
2,200,000 kg of mined material to be processed each year
V = mass/Density
V(annual)= 2,200,000 kg/ kg/m^3
V(annual)= m^3
V(daily) = 4.52 m^3
V(hour) = 0.19 m^3

10. ROVER DESIGN CMU Scarab chassis and suspension
Radioisotope Thermoelectric Generator
Target 1000 W
Mechanical lift arm with universal attachment

11. Rover Design
Oscillating disk cutter attachment for lunar regolith excavation
4-n-1 bucket attachment for scooping and transporting regolith
Bulldoze
Rake
Scoop
Undercarriage regolith scraper and tray

13. PROCESSING PLANT Annual Production System Volume System Mass
60 metric Tons per unit
implementation of 3 systems
System Volume
7.5x3x3.25 per each unit
System Mass

14. Storage Facility 20W rejection @ 20K cryocooled refrigerator
reverse turbo-brayton cycle
liquid helium working fluid
broad area cooling design
submerged tanks
refrigerator will be kept under inflatable protective membrane at crater floor
3x3x2m enclosure
waste heat from LH2 will be pumped to heat LOX to prevent freezing

15. Storage Tanks Cylindrical design 10m high
One (1) Liquid oxygen tank and One (1) Liquid hydrogen tank
Volume (LOX tank) = 120m3 D = 3.60m
Volume (LH2 tank) = 240m3 D = 5.50m
Insulated with 60 20mm layers of cryogel z (cryogenic insulator) and covered with 2 10mm aerogel (thermal insulator) outer layers

17. POWER RAPID-L 10 Year life Overall “small” and lightweight
200 kW
10 Year life
Overall “small” and lightweight
Solar initially
Gallium Arsenide
Later to supplement RAPID-L

18. Communication One main tower Similar to cellular towers High data rate
Relay information to one scarab
Scarab dispurses instructions

19. BUDGET Without inflation equation to determine the budget is:
(T-SLS-ISS)*.2+(SLS-Operations1)+(ISS-Operations2)= Available
Substituting in values in billions yields:
( )*.2+(2.62-1)+(3.1-0)= ~$6.8

20. Gantt Chart

21. Future Work Launch Sequence and Production Order
