“…An initial series of permeability tests conducted by our team with JSC-1A lunar soil simulant demonstrated that significant permeation of gases and fluids takes place in laboratory conditions that were designed to be analogous to the lunar surface (Patrick et al 2013(Patrick et al , 2014(Patrick et al , 2015Necsoiu et al 2018;Patrick et al 2019). There also are limits to the analogy our experiment represents with respect to the lunar surface.…”

“…The pit itself additionally offers architectural potential for utilizing external features. For example, where large pit openings exist, an opportunity to substantially increase livable volume areas by enclosing a lunar skylight pit with a pressurized dome allows inhabitants freedom from confines of living in modules or enclosed in a cave environment (Ximenes et al 2012;Patrick et al 2014).…”

“…Understanding the mechanical properties of the lunar regolith is important for ISRU and development of architectural habitability concepts, such as using regolith as feedstock for 3D printing of structures or enclosing a lunar skylight pit with a pressurized dome (Patrick et al 2014). This would help address the question of whether a lunar skylight can be pressurized to make it habitable.…”

Lava tubes are potentially important sites for the long-term human presence on the Moon because they provide shelter from surface hazards, including micrometeorites, radiation, extreme temperatures, and dust. The discovery of a lava tube opening or pit at Marius Hills in Oceanus Procellarum is compelling motivation for robotic and eventually human exploration missions to these sites for in situ investigations and site assessments to determine viability for habitation and utilization of lunar resources. We make the case for Marius Hills to be a high-priority landing site and present elements of lunar data analysis, instrument/payload concepts, science justification for robotic missions, and thematic geologic reconnaissance and remote sensing that should be conducted prior to any construction or emplacement of infrastructure. This is described as a “green reconnaissance” approach to lunar exploration and exploitation, which seeks to address such contamination factors as sprayed rocket exhaust and sublimating water in order to preserve science fidelity. We are developing a concept of operations called the Leto mission for a green reconnaissance approach to robotically access the Marius Hills sublunarean void.
