This two–level Crew Module (CM) variant will consist of the Observation Port option on both sides of the spacecraft on both decks (Images 1 and 2). Twenty–six astronauts will live in the CM for 1 day, or 24 hours. There will be no EVA ports installed on the CM.

Table 1 displays the Dynamic Mass for a CM that will house 26 astronauts with no spacesuits for a day.
Total Mass = CM2 Static Mass + CM2_26–00–01 Dynamic Mass
Total Mass = 2,961 kg + 2,360 kg
Total Mass = 5,322 kg
We will now modify the Crew Module designation by adding the mass:
CM2_26–00–01–5322
