The Mars Lander is a 5m diameter capsule with a volume of 25 cubic meters
The lander is planned to be used in five roles:
Life Support Unit – a lander containing systems for generating from Martian resources the energy, water and breathable air needed by the settlers.
Supply Unit – a lander carrying only cargo (supplies).
Living Unit – a lander containing an inflatable module to provide habitable space for the settlers on Mars.
Human Lander – a lander to carry the settlers to the surface of Mars.
Rover Lander – a lander to carry the two rovers to the surface of Mars.
