The Boeing Human Landing System (HLS) is a name of a proposed lunar lander concept by Boeing that was submitted to NASA on 5 November 2019 as part of the Artemis program and the NextSTEP H. The proposal was presented as the "quickest and simplest method" for a 2024 Moon landing. The lunar lander concept was rejected by NASA.
Overview
This is a proposal for the design of a lunar lander and lunar orbit spacecraft that would use the Space Launch System (SLS rocket) being developed by NASA. This concept was presented as a response to NASA's solicitation in May 2019 from about dozen companies for lunar lander designs.
The lander consists of a descent and ascent stage with the descent stage being able to deorbit the lander, which eliminates the need for a third transfer stage. The lander is designed to be launched on an SLS Block 1B rocket rather than assembled in space after multiple launches, reducing the number of mission-critical events from 11 to 5, and reducing mission complexity. The lander would not require to dock onto the Lunar Gateway and could dock with Orion directly in order to allow for a simpler mission profile. The lander would reuse key technologies from Boeing's CST-100 Starliner, so that the pressure vessel, life support and avionics systems could be flight-tested and human-rated before being integrated into the lander.
Intuitive Machines was selected to build and test the lander's engines and fuel tank structure. Aerojet Rocketdyne is also participating in the project.
Challenges
One problem with the lander is its high mass, and it requires to be launched by a SLS Block 1B. This variant of SLS is not expected to be operational until 2025 at the earliest. It was stated that the lander could be launched in parts with the descent stage launching on SLS Block 1 and the ascent stage launching on a commercial launcher and the two parts be assembled in lunar orbit in case Block 1B is not ready.
