Habitable volume (m³)

60

Total volume (m³)78
Volume per person (m³)10
Atmosphere mass (kg)96
Structural mass (kg)390
Power needed (kW)2.3
How to Use This Calculator
  1. Enter the number of crew members in the habitat.
  2. Set the mission duration to apply pressurized volume standards (NASA: 25 m³/person minimum for long duration).
  3. Input any dedicated volume for specific functions: lab, medical, exercise.
  4. Review the minimum total pressurized volume and recommended habitable volume.
  5. Compare to your habitat design volume to identify if additional modules are needed.

How the result changes with Mission duration (months)

What each input means

Crew size
Number of crew members.
Mission duration (months)
How long the crew will inhabit the space.
Gravity level (0-1)
0 = Microgravity, 1 = Earth gravity.
Comfort level (1-3)
1 = Minimal, 2 = Comfortable, 3 = Spacious.

What each result means

Habitable volume (m³)
Usable crew living space.
Total volume (m³)
Including equipment and storage.
Volume per person (m³)
Individual living space allocation.
Atmosphere mass (kg)
Air mass to fill the habitat.
Structural mass (kg)
Estimated pressure vessel mass.
Power needed (kW)
Power for life support and lighting.

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    4 parameters
    Crew size = 6, Mission duration (months) = 6, Gravity level (0-1) = 0, Comfort level (1-3) = 2 = 4 input(s) provided
  2. Calculate Habitable volume
    Habitable volume = round(crewSize * volumePerPerson)
    60 = 60
  3. Calculate Total volume
    Total volume = habitableVolume + equipmentVolume
    78 = 78
  4. Calculate Volume per person
    Volume per person = baseVolumePerPerson * comfortMultiplier
    10 = 10
