This crewed Mars lander was proposed by Boeing around 2014-2015, as part of a larger proposed lunar and Mars mission architecture. These vehicles were studied in response to NASA's proposed flexible path to Mars, which was to steadily build towards crewed Mars missions through a series of lunar orbital, lunar surface, asteroid, Phobos/Deimos, and finally Mars surface expeditions.

Boeing's Mars lander concept was to be highly common with their lunar lander, with the same ascent stage and the lunar descent stage now being repurposed as an ascent booster stage. The Mars descent stage would be newly developed, but with some component commonality to the other elements. Finally, a HIAD (Hypersonic Inflatable Aerodynamic Decelerator) heat shield would protect the vehicle during Martian atmospheric entry. It further built on lander development work Boeing performed on Altair for the Constellation program. The crew cabin used a carbon-composite structure, allowing for its distinctive shape.

All three stages plus the HIAD are included.
