DRM 3 Habitat Credit: NASA

Status: Study 1996. Gross mass: 137,406 kg (302,928 lb).

The crew would have to use the ascent stage and return capsule of the cargo lander to get back to earth. A scrub of the estimated masses in the first design reduced the mass of the crew lander by a third, to 60,806 kg on approach to Mars and 35,145 kg on the surface.
