The Boeing Human Landing System (HLS) was the name of a proposed lunar lander concept by Boeing that was submitted by Boeing 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 not selected for funding by NASA as part of Artemis in the 30 April 2020 announcement.
Overview
Boeing Human Landing System was 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 to launch the lander into Earth orbit and then place it in lunar orbit where it would rendezvous with the NASA Lunar Gateway and join up with a crew sent up in an Orion space capsule.[1] This design concept was presented as a response to NASA's solicitation in May 2019, where about a dozen companies proposed lunar lander designs.[2]
