s Figure 4-19: “Airlockless”-Airlock System, currently further developed at EADS, Germany 4.3.1.5.2 Middle level HMM Assessment Study Report: CDF-20(A) February 2004 page 266 of 422 This level, as shown in Figure 4-20 provides the main social area with a table to accommodate all crewmembers with folding chairs. A window at the table enables an overview of the outside area. A second window is placed on the opposite side. While sitting at the table the crew has an excellent overview over the whole habitat, as well as over the surface of Mars outside. The table is used for gathering, conferencing, observing and recreation. A galley and necessary infrastructure – all marked in green – is located here and an easy access to the hygiene facility is ensured. The stowage system (marked green) on this level allows quick and rational access.
s 4.3.1.5.3 Top level Figure 4-20: Plan of mid level HMM Assessment Study Report: CDF-20(A) February 2004 page 267 of 422 The crew cabins (marked in orange) are placed at the very top of the SHM – see Figure 4-21. One rationale for that is the closeness to the escape tunnel to the MEV. While resting, the crewmembers are able to observe the whole habitat, with the possibility of creating a private zone by cocooning themselves. Also the protection against radiation is better here, because the crew quarters are right underneath the MAV with its propulsion tanks.
