Advanced Space’s CEO Bradley Cheetham paid a visit to Morehead State University (MSU) in Kentucky today. Cheetham toured the Space Science Center, along with staff members for Senate Minority Leader Mitch McConnell and Congressman Hal Rogers. While there, the group discussed the successful Cislunar Autonomous Positioning System Technology Operations and Navigation Experiment (CAPSTONE™) mission, along with potential future collaborations with MSU.

May 18, 2023 | CAPSTONE Mission
Enhanced Mission to continue testing near-lunar communication and navigation technologies for months to come.
Advanced Space’s pioneering commercial satellite has completed its primary 6-month mission operating in the Near Rectilinear Halo Orbit (NRHO) that will be utilized by the Gateway lunar space station. CAPSTONE’s enhanced mission will continue to focus on demonstrating lunar operations and navigation technology. To mark the end of the Primary Mission, Advanced Space is providing an update on the mission’s accomplishments. While the completion of the Primary Mission is a significant milestone, the CAPSTONE mission is not complete. The mission team, led by Advanced Space, is now planning and preparing to execute the “Enhanced Mission” phase, which will extend the CAPSTONE spacecraft’s time in the NRHO up to 12 months. (more…)

The CAPSTONE Mission Team has been busy continuing to operate the mission in its planned Near Rectilinear Halo Orbit (NRHO). Thus far, since performing the NRHO insertion maneuver on November 13th, 2022, the spacecraft has spent 154 days operating in the NRHO completing 23 NRHO revolutions. During this time, the mission team has maintained knowledge of the spacecraft state well within the mission requirements using ground-based navigation tools and tracking measurements collected by the Deep Space Network including DSS-17 which is an affiliated site at Morehead State University in Kentucky. This navigation information has continued to support the design and execution of required maneuvers to maintain the orbit. Minimum maneuver size constraints have been sequentially reduced as the combined mission operations teams at Advanced Space, Terran Orbital, and Stellar Exploration continue to mitigate issues with a thruster valve. Since entering the NRHO the spacecraft has executed six Orbit Maintenance Maneuvers (OMM) using approximately 1.8 m/s of fuel. Although the mission plan was originally to do a maneuver every NRHO (approximately once a week), the higher burn threshold has reduced the number of maneuvers performed while also demonstrating the robustness of the stationkeeping strategy utilized by the mission which is the same strategy planned for the Lunar Gateway.

The CAPSTONE spacecraft continues to operate at the Moon and the vehicle is happy and healthy. The mission has accomplished 4 mission objectives and is making progress on additional objectives. Two mission objectives were completed during the transfer to the Moon and both directly informed Artemis 1 secondary payloads with regard to radio and ground station performance. (more…)

ABSTRACT
The Cislunar Autonomous Positioning System Technology Operations and Navigation Experiment (CAPSTONE) mission is an ongoing mission to serve as a pathfinder for cislunar operations and navigation for the Lunar Gateway and the greater Artemis program. As part of nominal operations, one of the tracking dishes that CAPSTONE utilizes is DSS-17 at Morehead State University. Through a series of necessary corrections, CAPSTONE has been able to generate radiometric measurements using this dish on the same order of noise magnitude as typical DSN measurements. This paper will provide an overview of the necessary processes and early performance of DSS-17 in CAPSTONE orbit determination.
