US Space Force, Japan launch sensor to bolster space surveillance above Indo-Pacific

The U.S. Space Force successfully launched a Space Domain Awareness payload aboard Japan’s Quasi-Zenith Satellite 7 (QZS-7) on August 10, 2023. This launch represents a significant step in a bilateral space initiative aimed at enhancing space surveillance capabilities above the Indo-Pacific region. The payload is part of a broader effort to improve the monitoring of space activities and ensure the security of space assets. The launch of QZS-7 completes a bilateral program that involves hosting U.S. sensors aboard Japanese navigation satellites. This program is designed to strengthen collaboration between the U.S. and Japan in the domain of space surveillance, reflecting the growing importance of space security in the context of regional and global stability. The integration of U.S. sensors into Japan's satellite constellation is a strategic move to bolster the capabilities of both nations in monitoring space traffic and potential threats. The addition of this second surveillance sensor to the Japanese constellation marks a significant enhancement in the U.S. Space Force's ability to conduct Space Domain Awareness operations. This initiative underscores the commitment of both countries to work together in addressing challenges in space and ensuring the safety and security of their respective interests in the increasingly contested space environment.
