Section 6 covers the different "Technology Trials" performed. First, Inflatable habitats were investigated to provide a "shirtsleeve indoor environment" for the astronauts. The article further suggests that if the cave's cross sectional surface area is properly sized, an inflatable cave liner could be placed in the cave and inflated requiring no additional support systems. The article then suggests using a dual-liner system in which an outer liner provides a surface against the cave surface and a pressure seal and an inner liner provides a habitat for the astronauts. Machinery and life support systems could be placed in between the redundant liners. The report also outlines methods of folding, manufacturing, transporting, replacing, and inflating these liners. Another main topic of this section is the "foamed in place" airlocks. These are designed to be shape-conforming to highly irregular openings along with easy to deploy and leak tight. Their final proposed system is an airlock unit with multiple extending telescoping legs to all of the cave walls. The space between the airlocks and the cave walls are then filled with hardening, spray-able, airtight foam. Next, the report outlines methods by which an inert pressure atmosphere could be created by pressurizing the gasses present on Mars, particularly Argon. This would allow human scientists only to wear breathing apparatuses and not require full pressure suits. It is suggested that cavernous spaces not be filled with oxygen or other reactive gasses as this would nullify any potential scientific value of the cave along with potentially being harmful to the humans breathing in the atmosphere inside. Finally, this section covers a system that would allow communication networks inside caves. This was also tested in a real cave (Robertson's Cave) and future modifications are suggested for increasing bandwidth and signal strength.
