American manned Mars lander. Study 1993. The first 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. The crew lander had a typical mass of 89,980 kg on approach to Mars and 60,710 kg on the surface.
