The successful arrival and commissioning of NASA’s CAPSTONE mission is a major step forward in demonstrating new navigation technologies and better understanding the unique environment around the Moon. CAPSTONE’s pioneering tests of a new spherical propellant-free spacecraft design and novel navigation techniques in cislunar space will help enable more complex and ambitious robotic and crewed missions to the Moon in the future.

One of the most exciting applications of CAPSTONE’s navigation demonstration is to enable future commercial lunar delivery missions with precise landing capability. By validating new small satellite navigation technologies like optical navigation and spacecraft-to-spacecraft radio ranging in the cislunar environment, CAPSTONE paves the way for landers carrying scientific or commercial payloads to pinpoint targeted landing sites on the Moon. This precise landing capability could open up entirely new regions of scientific interest and expand safe zones for future lunar outposts and infrastructure. CAPSTONE’s results demonstrating millimeter-level position knowledge will give commercial lander providers the confidence to precisely target specific destinations, expanding the regions accessible to future commercial cargo deliveries to support NASA’s Artemis program.

CAPSTONE’s navigation demonstration is also helping mature technologies needed for NASA’s Lunar Gateway, a small space station that will orbit the Moon and serve as a staging point for Artemis astronauts. Gateway will employ many of the same navigation techniques tested by CAPSTONE, like using spacecraft-to-spacecraft ranging to determine its position near the Moon. Validating these methods in the actual cislunar environment removes risks and helps optimize Gateway’s orbital design. With Gateway validated as a robust navigation platform, future crewed missions can rely on it as a navigation aide and safe haven in cislunar space, enabling ambitious sorties to more distant regions like the lunar south pole.

Beyond enabling precise lunar landers and validating technologies for Gateway, CAPSTONE’s results could shape future international partnerships and NASA’s plans for sustained human exploration of the Moon. With the emergence of new government and commercial capabilities from countries like India, Japan, and private American companies, CAPSTONE helps establish international standards and best practices for coordinating operations in cislunar space. This coordination will be crucial as more entities conduct activities near and on the Moon. CAPSTONE also explores new orbital configurations like a near-rectilinear halo orbit that could host future outposts supporting crews living and working on the lunar surface for extended periods. Validating navigation methods in this orbit removes risks from proposed “Gateway-like” stations that enable sustainable exploration of the lunar polar regions rich in resources.

By mapping the complex gravitational environment around the Moon with unprecedented precision, CAPSTONE also lays important groundwork for NASA’s ambitious human missions to Mars. Lessons learned establishing a robust navigational toolkit and operational practices in cislunar space directly translate to keeping astronauts safe on their months-long journey to the Red Planet. Improved understanding of orbital dynamics near the Moon also helps mission planners optimize trajectories for fast transits to Mars that maximize payload capabilities. Overall, CAPSTONE helps reduce the uncertainties of operating in deep space, bringing human missions to Mars and beyond one step closer to reality.

In conclusion, NASA’s CAPSTONE mission is already providing benefits for NASA and its commercial and international partners planning future missions to explore and develop the lunar vicinity. By overcoming challenges validating new technologies and expanding our knowledge of cislunar navigation, CAPSTONE removes substantial risks from ambitious robotic and crewed exploration initiatives involving the Moon, Mars, and beyond. The precise capabilities enabled by CAPSTONE’s demonstration of optical navigation and relative GPS will allow access to more challenging regions of the Moon while improving position knowledge crucial for future wayfinding. Overall, CAPSTONE’s achievements are helping ensure safer and more complex human exploration ventures deeper into the solar system in the coming decades. The insights gained from this pioneering mission will continue shaping NASA’s plans for sustainable lunar exploration and taking the next giant leap to Mars.
