China's Milestone: Classified Optical Satellite Launched to Geostationary Orbit

China successfully launched the classified Yaogan-41 optical satellite into geostationary orbit using its largest launch vehicle, the Long March 5. While the satellite's purpose was described as optical remote sensing for land survey, crop yield estimation, and environmental management, outside observers believe it has military applications. If positioned in geostationary orbit, Yaogan-41 will provide continuous observation of one-third of the Earth's surface, aiding in security, meteorology, climate studies, and environmental monitoring. The launch adds to China's growing on-orbit remote sensing capabilities and follows the recent launch of an experimental reusable spacecraft.
