Advanced Space Data Analysis Shows Recent Trajectory Maneuver was Successful
Westminster, CO (October 31, 2022) Advanced Space LLC., a leading space tech solutions company with breakthrough navigation technology, completed its fourth trajectory correction maneuver (TCM) for CAPSTONE on Thursday. TCM-4 was the fourth of six planned maneuvers en route to the Moon, targeting the precise orbit for the CAPSTONE demonstration. This follows the restoration of the spacecraft’s capabilities as it has recovered from the anomaly that occurred after TCM-3. (more…)

This study evaluates the potential observability benefits of space-based passive RF systems compared to other ground-based and space-based observers for cislunar Space Domain Awareness. TDoA and FDoA observations are used for orbit determination of objects in the lunar vicinity using observers in GEO and XGEO. The results are compared to ground-based observations in order to analyze the performance gains over existing architectures. Results show using space-based systems result in faster filter convergence and more accurate state estimates.
Over the past couple of weeks, the CAPSTONE mission team has been working to resolve an anomaly that occurred early last month and resulted in the spacecraft losing full 3-axis attitude control and entering into a spin stabilized state. Through extensive analysis and evaluation supported by a dedicated team of individuals on the mission team and key partners, the most likely cause of the anomaly was identified as a valve related issue on one of the spacecraft’s eight (8) thrusters. The partially open valve resulted in thrust from the associated thruster whenever the propulsion system was pressurized. To attempt a recovery from this condition, the mission team conducted multiple tests on the vehicle and evaluated extensive telemetry and simulation data and then formulated a plan for attempting recovery of the vehicle’s full 3-axis control.
