s 4.2.4 Surface habitation module Figure 4-3: Mars excursion vehicle Figure 4-4: Global dimensions Mars excursion vehicle HMM Assessment Study Report: CDF-20(A) February 2004 page 254 of 422 The SHM is the pressurised part of the MEV and consists of a main cylinder (see Figure 4-5). The global dimensions are shown in Figure 4-6. In a dedicated paragraph the interior of this main cylinder is presented. In Table 4-3 the pressurised volume is presented; it is less than the required 79 m 3 . The diameter of the SHM is kept small because free space is needed for the exhaust gasses of the engines of the MAV during ignition. To prevent contamination of Mars, the SHM may not been damaged
