s HMM Assessment Study Report: CDF-20(A) February 2004 page 98 of 422 • EVA-supported completion of MEV structural I/F • MEV Check-out, Commissioning Phase & Crew orientation commence at MEV delivery Once the MEV is added to the composite, the 90-day commissioning phase begins. If an in-orbit crew is required, dedicated commissioning crew shall be present for the first 60 days. Service Platform 5 2.8.3.9 Launches 26-27- Crew Figure 2-56: Launch of MEV EVA Airlock 1 Habitation Module • Launch 26 & 27 - Mars Crew delivery 30 days before departure – assumption, two launches of three crewmembers by Soyuz – alternative, single launch by shuttle 2.8.3.10 Launch 28- Cryogenic stage refueling (if required) • Refueling of Cryogenic stages performed during commissioning phase Note that the above assembly approach satisfies the constraint to minimise the Cryogenic fuel boil-off. However the assembly of the habitation modules at the beginning of the composite assembly sequence maximizes the life requirement of the equipment. Table 2-34 show a summary of the sequence defined above: MEV
