- SpaceX launched the private Athena lunar lander and NASA’s Lunar Trailblazer orbiter to search for water ice near the moon’s south pole, a key resource for future lunar habitation.
- Athena, carrying 10 NASA instruments, will land in the Mons Mouton region to drill and analyze lunar regolith for water and volatiles.
- Lunar Trailblazer will map water ice from orbit, complementing Athena’s surface exploration to identify water distribution and abundance.
- The mission supports NASA’s Artemis program, aiming to establish a sustainable human presence on the moon by the end of the decade.
- Discoveries from this mission could revolutionize space exploration, enabling lunar refueling stations and paving the way for missions to Mars and beyond.
In a historic step toward sustainable lunar exploration, a SpaceX Falcon 9 rocket launched the private Athena lunar lander and NASA’s Lunar Trailblazer orbiter on Monday evening from NASA’s Kennedy Space Center. The mission, spearheaded by Houston-based Intuitive Machines, aims to search for water ice near the moon’s south pole — a discovery that could revolutionize humanity’s ability to live and work on the lunar surface.
The launch, which took place at 7:16 p.m. EST, marked the second moon mission for Intuitive Machines under NASA’s Commercial Lunar Payload Services (CLPS) program. Athena, carrying 10 NASA science instruments, is set to land in the Mons Mouton region, a plateau near the moon’s south pole, where scientists believe significant deposits of water ice may lie. Meanwhile, Lunar Trailblazer will map water ice from orbit, complementing Athena’s ground-level findings.
“I’m very excited to see the science that our tech demonstrations deliver as we prepare for humanity’s return to the moon and the journey to Mars,” said Nicky Fox, associate administrator of NASA’s Science Mission Directorate, during a prelaunch briefing.
A mission to mine the moon’s resources
Athena’s primary objective is to explore the potential for in-situ resource utilization (ISRU) using lunar resources like water ice to support human habitation and fuel production. The lander’s Polar Resources Ice Mining Experiment-1 (PRIME-1) suite includes two key instruments: the TRIDENT drill, designed to extract regolith from up to 3 feet below the surface, and the MSolo mass spectrometer, which will analyze the samples for water and other volatiles.
“This time, hopefully, we land in a more precise position,” said Trent Martin, Intuitive Machines’ senior vice president of space systems, referencing the company’s previous mission, IM-1, which tipped over during landing in 2024.
Athena will also deploy two secondary vehicles: the MAPP rover, equipped with the moon’s first cellular network, and Grace, a hopping robot named after computer scientist Grace Hopper. Grace will explore the landing site’s surrounding area, including permanently shadowed craters, while MAPP tests long-range communication capabilities.
Lunar Trailblazer: Mapping water from above
While Athena focuses on the surface, Lunar Trailblazer will map water ice from lunar orbit. The orbiter, built by Lockheed Martin, will use its High-resolution Volatiles and Minerals Moon Mapper (HVM3) and Lunar Thermal Mapper (LTM) instruments to identify the form, distribution, and abundance of water on the moon.
“The most interesting [aspect] for many is the potentially large amounts of ice in the permanently shadowed regions of the lunar poles,” said Bethany Ehlmann, Lunar Trailblazer’s principal investigator. “Lunar Trailblazer will peer inside to see how much is at the surface.”
The data collected by both Athena and Lunar Trailblazer will be critical for future Artemis missions, which aim to establish a sustainable human presence on the moon by the end of the decade. Water ice could be processed into drinking water, breathable oxygen, and even rocket fuel, reducing the need to transport these resources from Earth.
Endless possibilities for lunar exploration
The discovery of water on the moon could unlock a new era of space exploration. Beyond supporting human life, lunar water could serve as a refueling station for missions to Mars and beyond. The IM-2 mission also carries a Laser Retro-Reflector Array (LRA), which will act as a permanent marker for precise spacecraft navigation, further enabling future lunar and interplanetary missions.
As Athena and Lunar Trailblazer begin their journey, the findings from this mission could reshape our understanding of the moon and pave the way for humanity’s next giant leap into the cosmos.
The successful launch of Athena and Lunar Trailblazer marks a pivotal moment in lunar exploration. By searching for water ice and mapping its distribution, these missions could provide the foundation for sustainable human settlements on the moon. As NASA and its commercial partners continue to push the boundaries of space exploration, the dream of a lunar outpost—and perhaps even a stepping stone to Mars—grows ever closer to reality. The moon, once a distant frontier, is now within our grasp, and its secrets may soon be revealed.
