Boeing Lunar Lander

The Boeing Lunar Lander, also called the Boeing Human Landing System, was a lunar lander and lunar orbit spacecraft concept that Boeing submitted to NASA on 5 November 2019 under the Artemis programme and the NextSTEP H call. It was pitched as the quickest and simplest route to a 2024 Moon landing. The design had a descent stage and an ascent stage, with the descent stage able to deorbit the lander, which removed the need for a separate transfer stage, and it was meant to launch on the Boeing built Space Launch System Block 1B and to reuse life support and avionics technology from the CST-100 Starliner. Intuitive Machines was to build the engines and fuel tank structure. NASA did not select it in its announcement of 30 April 2020, and its VR-3500 engines were reported in August 2021 to be going to Intuitive Machines for its Nova-M lander.
