s HMM Assessment Study Report: CDF-20(A) February 2004 page 150 of 422 Figure 3-25: Baseline design personal area - drawing The large exercise facility with the centrifuge (personal zone) is located in the back end of the main cylinder. It is spinning around the circumferential axis of the spacecraft. The other space is used for translation of the crew and for the life support system, which requires approximately 55 m 3 . This space has an unusual orientation, which is neither Skylab-type nor ISS-type due to the spinning centrifuge. It is used by building the LSS into this part because of its easy access for maintenance. Furthermore it has a large volume, which could be used by the astronauts in their leisure time for some zero-g experiments, as on Skylab. The next adjacent compartment is the workstation and maintenance level (personal zone), which has a Skylab-type orientation due to the dimensions of the module. For efficient use of space this looks like the most adequate orientation. In this area one treadmill, a medical, a science and a greenhouse rack and three workstations with computers are located. In addition each astronaut is equipped with a laptop computer. Figure 3-26 shows the next compartment, which has light hatches, houses the crew quarters (private zone). It has a 50-cm thick protection wall all around the compartment, stuffed with consumables and water for radiation protection in case of a solar particle event. This storm- shelter protects the crew for up to two days from such a solar storm. Inside are six crew quarters equally distributed with a translation path wide enough for large packets to be passed through.
s Figure 3-26: Baseline design private zone – drawing © LIQUIFER HMM Assessment Study Report: CDF-20(A) February 2004 page 151 of 422 The “top” part of the main module is occupied by the social zone which consists of the galley, the gathering area, the conference infrastructure and a recreational space. There are two windows to look outside.
