Further Details on Communications Issues with NASA’s CAPSTONE

NASA’s Cislunar Autonomous Positioning System Technology Operations and Navigation Experiment (CAPSTONE) experienced communications issues following its deployment on July 4. This is an update on the spacecraft health and efforts to regain contact between CAPSTONE and NASA’s Deep Space Network (DSN).  

Following CAPSTONE’s initial deployment on July 4, the spacecraft successfully deployed solar arrays, was stabilized, and began charging its onboard battery. CAPSTONE’s propulsion system was also readied for the spacecraft’s first maneuver.  CAPSTONE made initial contact with the DSN ground station in Madrid, Spain, followed by a partial contact with the Goldstone ground station in California. From these contacts, mission operators have been able to determine CAPSTONE’s approximate position and velocity in space.  

As a result of the communications issues, CAPSTONE’s first trajectory correction maneuver – originally scheduled for the morning of July 5 – has been delayed. This maneuver is the first in a series that are designed to make small corrections to increase the accuracy of the transfer orbit to the Moon, and the spacecraft remains on the overall intended ballistic lunar transfer while awaiting this trajectory correction.  

Teams are working to resolve CAPSTONE’s communications issues.
