NASA continues its ambitious quest to explore the lunar South Pole with its latest award under the Commercial Lunar Payload Services (CLPS) initiative. On August 29, 2024, the agency announced that Intuitive Machines, a Houston-based company, will receive $116.9 million to deliver six NASA payloads to the Moon's South Pole in 2027. This mission will contribute to the ongoing efforts of NASA's Artemis campaign, which aims to establish a sustainable human presence on the Moon and advance scientific knowledge for future exploration of Mars.
The CLPS initiative is designed to enable rapid and cost-effective access to the lunar surface through partnerships with commercial companies. Intuitive Machines' upcoming mission will mark the 10th CLPS delivery awarded by NASA and the fourth planned for the South Pole.
According to Joel Kearns, deputy associate administrator for exploration in NASA's Science Mission Directorate, this mission will allow NASA to "explore more of the Moon than ever before," with the goal of gaining valuable insights into the lunar environment.
Intuitive Machines' Role and Responsibilities
Intuitive Machines has been a key player in NASA's lunar exploration efforts. The company previously delivered six NASA payloads to Malapert A, a region in the lunar South Pole, in early 2024. With this latest award, Intuitive Machines will be responsible for integrating the payloads, launching them from Earth, ensuring a safe landing on the Moon, and managing mission operations.
"The instruments on this newly awarded flight will help us achieve multiple scientific objectives and strengthen our understanding of the Moon's environment," said Chris Culbert, manager of the CLPS initiative at NASA's Johnson Space Center in Houston. These objectives include identifying the presence of volatiles—such as water, ice, or gas—on the lunar surface and measuring radiation levels in the South Pole region.
The Payloads: Exploring Lunar Mysteries
The six payloads that Intuitive Machines will deliver are designed to tackle some of the most pressing questions about the Moon's composition and environment. Collectively weighing approximately 174 pounds (79 kilograms), these instruments will conduct a range of scientific experiments and technology demonstrations:
Lunar Explorer Instrument for Space Biology Applications: This payload will deliver yeast to the lunar surface to study its response to radiation and lunar gravity, offering insights into the challenges of sustaining life in space. Managed by NASA's Ames Research Center in Silicon Valley, California.
Package for Resource Observation and In-Situ Prospecting for Exploration, Characterization, and Testing (PROSPECT): Led by the European Space Agency (ESA), this suite of instruments will drill up to 3.3 feet (1 meter) beneath the lunar surface to extract and analyze samples, potentially revealing volatiles trapped in the Moon's frigid environment.
Laser Retroreflector Array: A collection of eight retroreflectors will enable precise measurements of the distance between spacecraft and the lander. This array, managed by NASA's Goddard Space Flight Center in Greenbelt, Maryland, will serve as a permanent location marker on the Moon.
Surface Exosphere Alterations by Landers (SEAL): This payload will investigate the chemical response of lunar regolith—loose, rocky material on the Moon's surface—to disturbances caused by spacecraft landings. Managed by NASA Goddard, SEAL will help scientists understand how landings affect the composition of lunar samples.
Fluxgate Magnetometer: This instrument, also managed by NASA Goddard, will characterize magnetic fields on the lunar surface, improving our understanding of energy and particle pathways.
Lunar Compact Infrared Imaging System (LCIRIS): Managed by the Laboratory for Atmospheric and Space Physics at the University of Colorado at Boulder, LCIRIS will deploy a radiometer to explore the Moon's surface composition, map temperature distribution, and assess the feasibility of future lunar resource utilization.
A Step Closer to Sustainable Lunar Exploration
This mission is a significant milestone in NASA's broader efforts to establish a long-term human presence on the Moon. By delivering these sophisticated instruments to the lunar South Pole, NASA aims to deepen our understanding of the Moon's environment and unlock new possibilities for future exploration. The knowledge gained from these experiments will be crucial for the continued success of the Artemis campaign, which seeks to return humans to the lunar surface and eventually pave the way for human missions to Mars.
Two additional CLPS flights are slated for launch near the end of 2024, one of which will include Intuitive Machines' delivery of NASA's first on-site demonstration of searching for water and other compounds beneath the Moon's surface.
