The Artemis Generation: To the Moon — this time to stay!

The Artemis Generation: To the Moon — this time to stay!

We are in a new era of lunar exploration, development and settlement.

Originally posted to Space.com on 16 April 2023.

On June 28, 2022, CAPSTONE launched into space on a dedicated rocket as the first mission of the Artemis program, ushering in a new generation of lunar exploration, development and settlement. With NASA’s leadership and global involvement, we are entering a period that will define the future of space exploration: the Artemis Generation.

As the architects of CAPSTONE, our team has learned first-hand the challenges of lunar missions. From communications and propulsion anomalies to suspected radiation upsets, traveling to the moon and operating there is not an easy task. During these challenges, however, the best of the industry united and we overcame — such alignment is the key to successful long-term lunar development. (more…)

CAPSTONE Mission: 17 April 2023 Update

CAPSTONE Mission: 17 April 2023 Update

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.

CAPSTONE Mission Demonstrating Utility and Resilience at the Moon

CAPSTONE Mission Demonstrating Utility and Resilience at the Moon

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…)

Utilization and Validation of DSS-17 on the CAPSTONE Lunar Mission

Utilization and Validation of DSS-17 on the CAPSTONE Lunar Mission

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.

Advanced Space Leads First Ever Commercial Mission to Operate at the Moon

Advanced Space Leads First Ever Commercial Mission to Operate at the Moon

NASA’s investment in small business boosts the economy and enables the future of space exploration.

Westminster, CO – Advanced Space LLC., a leading space tech solutions company, is the first commercial entity to own an operational satellite at the Moon. CAPSTONE, the Cislunar Autonomous Positioning System Technology Operations and Navigation Experiment, has finalized its insertion into a Near Rectilinear Halo Orbit (NRHO). Now that history has been made, the small spacecraft is ready to begin operations for NASA in support of the Artemis program. This milestone also marks the beginning of the navigation experiment that will lay a foundation for future missions. Consistent with the company vision to enable the sustainable exploration, development, and settlement of space, Advanced Space has worked to support the Nation’s focus on returning to the Moon. CAPSTONE is tasked to understand the operational characteristics of the orbit, perform technology demonstrations to help reduce the risk for future spacecraft, and to validate innovative navigation technologies.
