American manned Mars lander. Study 1996. The second version of the NASA Crew Lander for the design reference mission would land the crew and a Mars surface habitat on the surface near the previously-landed cargo lander.

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.
