Blazing a Trail: Latest Updates on Lunar Trailblazer
Lunar Trailblazer began the Assembly, Test, and Launch Operations (ATLO) phase of the program on Oct. 27, 2022 and is progressing toward a launch date in late 2024. The Lockheed Martin team installed all of the spacecraft’s instruments, including NASA JPL’s???(HVM3) – a spectrometer that measures infrared light that is absorbed by water.
ATLO environmental testing began in February 2023.. It will then be stored at Lockheed until fall of 2024 when it is shipped to the launch site in Florida and launch aboard a Falcon 9 rocket as a ride-share along with Intuitive Machines’ IM-2 CLPS lander.

Looking for Water on the Moon
Lunar Trailblazer will measure the form, abundance and distribution of water and hydroxyl (a water molecule minus one part hydrogen) on – and make high-resolution maps of various regions of – the lunar surface. This mapping of water on the Moon could help NASA better identify future Moon landing sites for humans (on missions like Artemis) and discover new clues about the delivery of water and other materials to the Earth-Moon system over time.
The Lunar Trailblazer spacecraft bus began development at Lockheed Martin in 2020 and is set for a rideshare launch with IM-2 in late-2024 or early 2025.?Lockheed Martin designed and is?building and integrating Lunar Trailblazer under contract with Caltech. Lunar Trailblazer is led by Caltech principal investigator, Bethany Ehlmann, and the project is managed by NASA's Jet Propulsion Laboratory.
Small But Fit for a Complex Mission
Lunar Trailblazer is part of NASA’s??(SIMPLEx) mission class. SIMPLEx missions are those that use small spacecraft for exploration. Lunar Trailblazer is approximately 450 pounds. They go to space by hitching a ride on existing launches.
Lunar Trailblazer utilizes Lockheed Martin’s new?Curio platform?– a novel and scalable deep space SmallSat spacecraft architecture that allows the deep space exploration community to investigate scientific questions at less cost. The foundational architecture is also customizable to be able to meet a specific mission’s needs.
The spacecraft also builds on Lockheed Martin’s strong heritage in deep space exploration missions. Lunar Trailblazer’s guidance, navigation and propulsion systems are modeled after NASA’s successful??to the Moon. GRAIL’s two spacecraft – designed and built by Lockheed Martin – used a hydrazine propulsion system that allowed them to achieve the needed thrust at the needed mass.?
The Future Lunar Economy
For humans to go back to the Moon and stay there, we need resources and a system to access them: a full-scale lunar economy. The water Lunar Trailblazer will map on the Moon’s surface may become a critical building block of this specialized space economy. In an ideal future state, humans will be able to both drink the Moon’s water and use its hydrogen and oxygen atoms for fuel.?
Lockheed Martin has developed a vision of how this lunar economy could be developed. 美诱直播 call it a Water-Based Lunar Architecture.?
