In-Situ Spare Manufacturing
ISRU Panel Manufacturing Process
The in-situ spare manufacturing process is a 200-kilogram fabrication system that produces micrometeoroid and orbital debris (MMOD) Whipple shielding panels directly on the lunar surface. Operating at 2,000 watts, the equipment shapes locally smelted aluminum sheet stock through stamping or roll-forming dies, integrating it with Earth-supplied bulk Nextel and Kevlar to produce ten panels per month. Establishing local fabrication eliminates continuous resupply reliance for bulky structural elements damaged in the harsh lunar environment. Designed for continuous long-mission uptime in the lunar vacuum, the manufacturing hardware provides a 10,000-hour mean time between failures across a 20-year operational lifetime.
In-situ manufacturing process producing MMOD panel spares from ISRU Al stock (via L1-MFG smelting), enabling self-sufficient spare production.
Purpose
In-situ manufacturing process producing MMOD panel spares from ISRU Al stock (via L1-MFG smelting), enabling self-sufficient spare production.
Context
Child of L2-MMD-SPARE within the Lunar Ark system
Principles
- ▸Al stock from L1-MFG smelting (ISRU origin)
- ▸Whipple panel forming via roll-forming or stamping
- ▸Nextel/Kevlar imported from Earth in spare bulk
- ▸Self-sufficient Al panel production
- ▸QC verification via L3-MFG-QC
Typical implementations
- ▸NASA In-Space Manufacturing program
- ▸ISRU manufacturing studies
- ▸Industrial roll-forming heritage
Lunar considerations
- ▸ISRU Al closes the production loop for primary structural element
- ▸Polymer/ceramic stuffing imported in long-shelf-life bulk
- ▸Long-mission factory uptime
