Description	Carries a mirror-selfie payload. First international commercial mission for CAS Space, one of China’s emerging launch providers and ThumbSat's strategic and launch partner. The mission was made possible through close collaboration between CAS Space and ThumbSat, who together designed a specialized deployer — the result of a small, international team uniting talent from Mexico, the UK, China, and beyond. Through its outreach program, ThumbSat placed ground-receiving stations with students and citizen scientists across Mexico. With antennas and software provided free of charge, volunteers were able to track signals from orbit and participate directly.
Results	Perfect orbital insertion at 07:46:00 UTC on 19 Aug 2025 via CAS Space Lijian-1 Y10. First confirmed communication success: expert-validated ThumbSat transmission captured by the distributed ground network. Operated at the 10 cm radar detection threshold, near the edge of detectability for ground-based tracking. Orbital confirmation enabled generation of accurate TLE sets for continued predictions. Zero safety or compliance incidents; all transmissions within license terms. Strong public participation and positive feedback across program events. 100% subsystem validation.
