Revision as of 04:50, 8 November 2019
The Boeing Human Landing System (HLS) was submitted to NASA on November 5th as part of the Artemis Program and NextSTEP H. The Proposal was advertised as the quickest and simplest method for a 2024 moon landing.
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 rather than assembled in multiple launches, reducing the number of mission critical events from 11 to 5, reducing mission complexity. The lander would also not require the 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, which would allow systems like life support, the pressure vessel, and avionics system to be flight tested and human rater before being integrated into the lander.
Intuitive Machines was selected to build and test the landers engines and fuel tank structure, Aerojet Rocketdyne is also participating in the project.
Potential Problems
One problem with the lander is that it uses a SLS Block 1B as it's launcher. This variant of SLS is not expected to be operational until 2025 at the earliest with he current plan. Boeing suggests cutting funding for the Gateway in order to accelerate development of the Exploration Upper Stage and allow for Block 1B to be flying by 2024.
