Permanent outpost on the surface of the Moon could immediately exploit lunar regolith to protect humans from significant exposure to harmful levels of radiation. Just two meters of lunar regolith dumped within the walls of a lunar regolith habitat could reduce annual cosmic radiation exposure below the maximum legal limit for radiation workers on Earth (5 Rem per year) during the solar minimum while also protecting astronauts from radiation exposure from major solar events. Protection from micrometeorites and extreme temperature fluctuations would be an added benefit of insulating a lunar habitat with regolith.
A single lunar habitat derived from the technology used to make the light weight 8.4 meter in diameter hydrogen fuel tanks for the SLS could provide two levels of floor space approximately 111 square meters in area. That would be more floor space than the average home in Germany, Japan, Sweden, Italy, Spain, Russia, and in the UK. The deployment of such habitats for the private commercial community could also be used as lunar hotels for space tourist or to house workers for private companies involved in the export of lunar water or regolith for government and private entities.
Creating solid pavement for the deployment of habitats and other lunar outpost components upon dust free surfaces could be created by using mobile robots to pave and sinter lunar regolith. This could eliminate tracking in deleterious lunar dust into pressurized habitats when astronauts are working in the paved lunar outpost area.

Human biowaste could be converted into methanol through pyrolysis. Methanol and oxygen can be used with fuel cells to produce electricity for back up energy during periods of lunar darkness. The water produced from the combustion of methanol and oxygen can be recycled. The CO2 produced from the manufacture of methanol and from the combustion of methanol in fuel cells can be used to enhance the growth of indoor lunar crops. Small portable methanol fuel cells could also be used to provide power for pressure suits during lunar excursions.
Nitrogenous biowaste, such as urine, could be used as fertilizer for lunar crops.
However, there is some evidence that substantial quantities of carbon and nitrogenous material may also be a significant component of the permanently shadowed areas at the lunar poles. Astronauts stationed at lunar outpost at the lunar poles could used to explore and to quantify the amount of volatiles located within the shadowed regions.

Outposts originally designed for the lunar surface could also be utilized on the surfaces of Mars, Mercury, and Callisto and even on the meager surfaces of large asteroids and on the moons of Mars.

Permanent outpost on the Moon and Mars and on other worlds, would allow the continuous exploration of those surfaces by both humans and robots. Unmanned solar or nuclear powered rovers on the lunar surface, operated by humans on Earth, could visit and collect samples from practically every area on the surface of the Moon. The collected rocks and soil could then be returned to the lunar outpost for immediate study or for eventual export back to Earth.
On Mars, both robotic rovers and hydrogen blimps could be utilized to continuously explore the Martian surface. Such robots could be operated in real time by the astronauts on the Martian surface or in orbit around Mars at a space station. Again, the collected samples by the remote controlled robots could be returned to the Martian outpost for immediate study or for eventual export back to Earth.
A permanent US government presences on the surface of the Moon and Mars will also enhance the ability of private American companies to protect their assets from potentially hostile foreign entities that will probably also be on these new worlds by mid century.
