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.
