SPORE Project Outline

Phase One – Define all the components of the Shielded Pressurized Oxygen Resource Extraction concept

The first step is to figure out all the pieces needed to make SPORE work:

  • Why SPORE is necessary.
  • Relevant Lunar geology (selenology)
    • Not needed. 
      • We don’t know much about the Lunar regolith and almost nothing about the mega-regolith.
      • What we do know shows the regolith and mega-regolith to be highly variable in particle size, distribution, and composition.
      • SPORE needs to operate anywhere on the Lunar (and other) surface. The local geology needs to be largely irrelevant. Clever design is going to be the key to making SPORE work.
      • I started working on this at SPORE Apollo 12 Regolith and Mega-Regolith Characterization.
  • SPORE design
    • Version 1 – I had originally thought the Pressure Hull and the Shield Wall would be separate components. Now I think they should be the same thing (the Shield Wall IS the Pressure Hull). This page lays out the advantages and disadvantages of both.
    • Version 2 – This page I move from burying habitats (the current paradigm) to creating habitats while tunneling. I note the advantages and disadvantages of both ideas.
    • SPORE Surface Functions – Some Homestead functions must be located on the Lunar surface. This is a working list of these functions.
  • SPORE physical components
    • Shield wall (also just called Shield on some pages)
      • Materials
      • Designs
      • Construction tools
      • Maintenance tools
    • Radiation/Kinetic barrier
      • Loose regolith blanket
      • Bagged regolith
      • Sintered regolith
    • Excavation tools
    • Material transportation tools
  • SPORE techniques
    • Excavation methods
      • Linear Plate (aka Liner Plate) method
      • Tunneling Shield
      • Dust control
      • Oxygen atmosphere pressure loss mitigation
    • Material transportation to processing machinery
    • Shield wall construction
      • Optimal 100% oxygen atmospheric pressure
    • Iron pressure hull habitat construction
      • How are we going to build the pressure hull while still allowing access to more excavation?
  • Existing research done on similar concepts
    • On going – I’ve done a lot of research already and haven’t run across anything like SPORE. Maybe there’s an article out there hidden behind a paywall or buried in an obscure article.

Phase Two – Experiments

  • SPORE Pressure Experiment 1 – I had originally thought to try to determine the atmospheric loss through the exposed regolith. The plan was to build various small scale SPORE shield walls and pressure barriers and test them with various regolith and mega-regolith simulants. After a lot of reading and thinking, I decided that any data collected just wouldn’t be very useful.
  • SPORE Experiment 2 – In the works!

Phase Three – Working (non-flight ready) scale prototype of a SPORE structure

  • The goal is to have a prototype “on the shelf”. I won’t know all the steps necessary until I am further along.

Phase Four – Public outreach and education

  • Scale non-functioning mockup
  • Publish data and findings
  • Book – written for non-scientists
