Cargo Lander Reference Version 3

American manned Mars lander. Study 1993. The second version of the NASA Cargo Lander for the design reference mission 3.0 was similar in concept to the first but mass was reduced nearly 30% by a thorough study and scrub of each element.

The cargo lander would land an Earth Entry/Mars Ascent Capsule, an ascent stage, and an ISRU plant on the surface that would produce propellant for the crew's return journey from the Martian atmosphere. It had a typical mass of 66,043 kg on approach to Mars and 44,440 kg on the surface.
