The Lockheed Martin Lunar Lander is a series of design concepts by Lockheed Martin for a crewed lunar lander.
The first proposal, Mars-Precursor Lunar Lander is a reusable crewed lunar lander first unveiled in October 2018, and it is being proposed to NASA for funding and fabrication. NASA specified that it would wait until 2024 to decide the date and method for a crewed lunar lander, and have hinted at seeking a crewed lander no heavier than 6 MT. The reusable lander would enable sustainable lunar surface exploration. The second proposal, revealed on 10 April 2019, is a 2-stage lander proposed to meet Vice President Mike Pence's challenge to return humans to the Moon by 2024,[1] which became the Artemis Program.
Both proposals are based on Orion spacecraft's hardware, and are designed to take astronauts from the Lunar Gateway — a proposed habitat that NASA plans to build in orbit around the Moon — to the lunar surface and advance technology needed to explore Mars.
NASA did not select this design for the Human Landing System component, but Lockheed Martin is providing the ascent portion of the Integrated Lander Vehicle, which was selected as a second HLS provider.
