Questions

3. 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.

7. Lunar Communication Communications tower Relay messages to main rover
Similar to cellular towers on Earth
Relay messages to main rover
Main rover relays commands to other rovers

8. Scarab Rovers

9. Scarab Rovers 2.5 kW Brayton Rotating Unit 550 N Excavation Force
125 cm/s
Traction/Mass Increase - Under belly scoop

10. LSMS Used for unloading cargo, moving material and construction
Different attachments for welding, drilling, and grabbing
Can be operated manually or autonomously

11. Power & Energy Solar power for initial base construction
GaLnP2 Cells
Triple layer for max efficiency
29.5% efficient
403.2 W/m^2
290 days of consecutive sunlight

12. Base Layout

13. Regolith Mining Rotating Cutter Head
Mined regolith heated from energy production process to separate water
huge energy savings
Saves transporting 2,000,000 KG - 8 KM to crater rim for processing
Winch transport system to carry water to crater rim

14. Processing Plant
CRIWE Filtration
