This Crew Module (CM) variant will consist of the Observation Port option on both sides of the spacecraft (Image 1). Ten astronauts will live in the CM for 7 days. There will be no EVA ports installed on the CM.

Table 1 displays the Dynamic Mass for a CM that will house 10 astronauts with no spacesuits for a week.
This particular CM variant will incorporate a flexible emergency airlock with a mass of 27 kg. The airlock will be attached to the bottom interior hatch. It will be deployed by lifting the top part of the flexible airlock and attach it to the top hatch (Image 2). After the interior of the airlock has been evacuated of air, the upper hatch can be opened and the astronaut can ingress the airlock. The airlock is re–pressurized and the astronaut extracted.

Total Mass = CM1 Static Mass + CM1_10–00–07 Dynamic Mass + Emergency Airlock
Total Mass = 1,577 kg + 1,258 kg + 27 kg
Total Mass = 2,863 kg
We will now modify the Crew Module designation by adding the mass:
CM1_10–00–07–2863
