Pocket Guide to Lunar ActivityFirst we will reinstate the capability to land people there, sustain them for a few days, and return them.
This time, we will not be fundamentally restricted to Nearside, near-equatorial sites. Small crews will explore their surroundings, collect samples, set up simple surface systems (for power, communications, and scientific and engineering experiments), and learn how their equipment really operates. We will use simple rovers to explore regions surrounding the landing site. We will use remote sensing and surface exploration to seek unique places where useful materials or scientific phenomena are concentrated.
After determining where it makes sense to “put down roots,” we will bring larger habitation and workshop elements, and construct radiation shields around them using assembled structure elements and lunar regolith. We will commission power plants that can operate through the two-week night time. We will explore the strange regions where permanent shadow and near-permanent sunlight are close together, where there may be ice resources, and locations on the Farside where Earth is never directly visible. We will grade and pave the surface locally to make it safer, cleaner, and more predictable for people, mobile equipment and automated machines to operate. Crew members will begin to specialize: experiments, exploration, construction, housekeeping, jury-rigging, and repair.
Among the engineering experiments will be some that test practical ways of operating, constructing, excavating, beneficiating, and ultimately producing useful products from lunar material: oxygen for propellant and life support; masonry, glass, and iron for making things; nitrogen and other light elements for air and nutrients. We will learn how to cultivate, protect, and harvest plants and animals. We will try a wide variety of solutions to these challenges, selecting and scaling up the ones that work well.
We will establish test sites where we can practice techniques being designed to explore near-Earth asteroids and Mars. We will build research facilities that Earthbound scientists use by proxy to perform unique astronomical observations, or uniquely dangerous experiments. If it turns out to be economically sensible, we will establish large-scale production of lunar-derived propellants and construction materials to enable cis-lunar development, and large-scale generation of energy for Earth. We will build destinations on the Moon for business and leisure visitors. Eventually the scale and viability of these activities will cross the threshold that defines settlement, and humanity will become a two-planet species.

Sherwood, Jun07 Rutgers Symposium on Lunar Settlements 2007 12
Pave for dust control
• Lunar regolith + hard vacuum = !
• Design around mitigation of bad effects– Pave roadways and work areas
• Grade, then stabilize– Compaction vs. using the natural resource
• Paving alternatives– Compacted gravel– Paving blocks– Direct sintering
Imagine an investigation that prototypes various methods to determine what works best to control dust
Sherwood, Jun07 Rutgers Symposium on Lunar Settlements 2007 13
Establish a colony of continuously active robots
• Kurzweil singularity – what will we expect of robots by 2025?– Benefit-to-cost ratio– Human extension and enhancement
• How much of an outpost could be built robotically?– Shape a predictable environment– Establish, verify routine operations– Build radiation shelters
• Remote, dynamic construction site– Productivity– Public interest– No downtime during, between human visits
Imagine “looking in on” a robotic colony as it changes every day
Sherwood, Jun07 Rutgers Symposium on Lunar Settlements 2007 14
Kitchen science
• How “normal” processes work on the Moon, and affect routine activities– Convection, mixing, drainage, evaporation…
• The practical things– How to cook, how to clean, how to live
• Must be done in situ
• Investigations akin to play– Inherently interesting: defining a new way for humans to live
Make it personal: what do you do every day…and how will we learn to do these things on the Moon?
Sherwood, Jun07 Rutgers Symposium on Lunar Settlements 2007 15
Designer biology
• 1960s quiz: Which will occur first?– Transgenic and knockout mice
– DNA fingerprinting as admissible evidence
– Cloned pets
– Moon base
• What biological “miracles” will be common by 2030?
• Plants and animals optimized for lunar conditions– Hard radiation, low atmospheric pressure, different partial
pressures, long dark periods, strong ultraviolet, economical geometry, alien soil, nutrient concentration…
Imagine a laboratory on the Moon devoted to developing a novel lunar ecology that meets our needs
Sherwood, Jun07 Rutgers Symposium on Lunar Settlements 2007 16
Tend the machinery
• You think YOU spend weekends working on your house…
• Economics will drive routine lunar ops to be machine-mediated
• “Highest and best uses” of humans– Exploration
– Jury-rigging new solutions
– Maintenance and repair
• Shirtsleeve workshop will emerge as critical need– Long night-time, diurnal rhythm
Imagine the public appeal when “tending” grows to include husbandry of living things
Conduct science to gain new knowledge
Sherwood, Jun07 Rutgers Symposium on Lunar Settlements 2007 18
Search for pieces of ancient Earth
• Oldest Earth rocks miss the first 1/5 of Earth history– Tectonic recycling, weathering obliterate the record
• Lunar environment preserves solar system history
• If SNCs could come from Mars to Earth…– Lunar regolith must contain Earth rocks
• How would we recognize them?
Imagine a scientific campaign using robots, humans, searches, modeling, sample recovery, and in situ and terrestrial lab analysis to gain insight into the missing history of Earth
Sherwood, Jun07 Rutgers Symposium on Lunar Settlements 2007 19
Observatories to open new wavelength regimes
• Every new wavelength window has yielded new discoveries about how the universe works– Space flight opened several windows above Earth’s atmosphere
• Two unexplored windows remain: they require both a space location and very large detectors
• Low-frequency ( > 10m) radio– Large array of simple dipole antennas
• High-energy cosmic rays– Detector/regolith lasagna
Imagine robotic preparation and deployment of new kinds of observatories…and imagine new discoveries being made
Improve the human condition
Sherwood, Jun07 Rutgers Symposium on Lunar Settlements 2007 21
Virtual real-time network for public engagement
• Voters of 2030 will not be born for another 5 years– How much will they share our values?
• Today’s media world: interests are a click away
• Public will expect to be embedded in humanity’s lunar adventures via high-fidelity telepresence– Anytime-broadband infrastructure– Privacy challenges
• Not “Education and Public Outreach”– Digital-wallpaper live feeds of lunar wilderness or worksites– Moonwalks in immersive VR – in junior high– Lunar inhabitant blogs and chat
Imagine how the issue of “relevance” will vanish as lunar living becomes just another part of our daily life
Provide economic growth
Sherwood, Jun07 Rutgers Symposium on Lunar Settlements 2007 23
Public-private lunar development corporation
• Public-private partnership is required to jumpstart viable commercial enterprise– Sparse and frangible business opportunities
– High barriers to entry
• Port authority model1. Insures core service continuity, predictable business conditions
2. Promotes competitive growth via long-term, competitively-awarded service contracts
3. Reinvests its own profits to improve the port infrastructure
Accelerate commercial implementation of routine services – Habitation, energy, communications, propellant production,
consumables resupply, food production, waste management, construction, maintenance, housekeeping, recycling, security
Enable solar system exploration
Sherwood, Jun07 Rutgers Symposium on Lunar Settlements 2007 25
Planetary protection protocols for Mars
• Mars is very different from the Moon– Yet, we can design lunar operations to validate Mars techniques
• Key feature of human Mars exploration is investigation of “special areas” where life might be– Paradox: require human field work, but most susceptible to
contamination
• Can sub-optimize lunar ops to emulate Mars conditions– Far-side outpost + 6-mth orbital loiter + 1-yr base ops with Mars-
type systems + 6-mth orbital loiter = simulation
– Help is days away, rather than months
Imagine rehearsing protocols for exploring “special areas”– Sterile robots, habitat gloveboxes, dust control, ops procedures
Establish human settlements off Earth
Sherwood, Jun07 Rutgers Symposium on Lunar Settlements 2007 27
Expand life and intelligence beyond Earth
• Über-objective – focuses the others– Long-term purpose– Operations tailored for permanence, local supply, economic
growth, self-sufficiency, survival, procreation, and new beginnings
• Settlement resonates with people– A dwarf planet only three days away…with resources– Opens alternative industrial space futures– Strategic destination for passenger travel– Noah’s Ark reassurance
• Key architecture and investment decisions– Reusable hydrogen/oxygen transportation systems– Sites selected to scale up resource production– Regenerable life support, genetic modification– Habitat construction– Genuine economic development
Imagine using settlement to focus what we do on the Moon now
