Placing the LSS at the base (marked blue) of the SHM creates a strong orientation and good
overview throughout the habitat. The section on the left shows that the working area is placed in
a split level between the EVA area (marked red) and the main social zone. From there the
astronaut can overlook the whole habitat, without interfering with the private space of fellow
astronauts (marked orange).
Figure 4-14: Sectional drawings of Option 2
The two sections explain in detail the different zones, functions and infrastructure of the habitat.
On the left the different lines of sight are indicated by black arrows to enlarge the space on a
perceptive level. The overview over the habitat is possible from each point of view but through
introducing a split level zoning is made possible and therefore creates a distinct set of different
spaces allocated to different functions and crew performance.
The upper part of the habitat is the private zone with some cocoon-type crew quarters (bunk
beds) which can be also used as stairs for a secondary option of circulation. Below the social
zone with the galley, are located the hygiene facilities, a table to accommodate all three
crewmembers with a window and the stowage area (marked in green on right section).
The yellow curved arrow on are the right-hand side of Figure 4-14 points towards the emergency
exit – an easy path to follow and also in the line of sight. This translation path is quite roomy and
free of obstacles.
