NASA CAPSTONE Project Ends, But The Cis

CAPSTONE began its life in June 2022 as a first-of-its-kind U.S. commercial mission to orbit the Moon. It explored three-body orbits that blend Earth’s and the Moon’s gravity to reduce fuel use for staying on a stable path around the Moon. This approach has helped set up future exploration and science missions. After finishing its primary mission, CAPSTONE received a 15-month extension to serve as a testbed for advanced communications, networking, autonomous navigation, and software-driven satellite technologies. The plan was to show that CAPSTONE’s existing hardware can host fresh applications after launch, making it a cost-effective platform for lunar technology demonstrations. The extended mission focused in part on testing a new way to operate in deep space. The study looked at how CAPSTONE could function with limited or irregular contact with Earth, a common challenge for distant missions. The project also evaluated how several new capabilities work together on the same spacecraft in a real lunar setting. This includes autonomous navigation and new communications methods that don’t rely on constant back-and-forth with Earth. Two CAPSTONE Vital Experiments Two experiments used software-defined infrastructure to advance critical mission needs. The autoNGC system (autonomous Navigation, Guidance, and Control) lets a spacecraft determine its own position, its destination, and the route to reach that destination without immediate ground instructions. CAPSTONE marked the first time autoNGC was tested near the Moon, building on earlier tests in Earth orbit. In addition, the project tested a delay/disruption tolerant networking (DTN) approach. DTN is designed to handle long delays and gaps in deep-space communications by storing data on the spacecraft and sending it later when a link is available. This was the first time these DTN protocols ran beyond Earth orbit and inside NASA’s Flight System framework. The mission was designed and built by Terran Orbital and operates under Advanced Space. NASA’s Ames Research Center coordinated the Small Spacecraft and Distributed Systems program, with support from the Small Business Innovation Research program. The SCaN Division at NASA Headquarters managed the autoNGC and DTN demonstrations during the extended mission. Ultimately, CAPSTONE’s extended mission shows that the tested technologies can operate effectively in a real lunar environment, supporting future NASA missions and broader deep-space exploration that require strong navigation, autonomous operations, and reliable communications.
