ExPace successfully launched two Earth observation radar satellites on September 17, 2026, from the Jiuquan Satellite Launch Center in northwestern China. The SpaceTY-51 and SpaceTY-52 spacecraft represent the latest additions to China's growing constellation of remote sensing satellites. Built by Chinese satellite manufacturer SpaceTY, these Earth science missions are designed to collect synthetic aperture radar imagery for applications including land monitoring, disaster assessment, and environmental surveying.

The Kuaizhou 11 solid-fueled launch vehicle, operated by the private Chinese company ExPace, carried both satellites to orbit. Kuaizhou 11 is a four-stage rocket capable of delivering payloads to various low Earth orbits and has become a workhorse for China's commercial space sector. The launch from Jiuquan, one of China's primary spaceports, reflects the facility's continued role in supporting both government and commercial satellite missions.

The mission achieved a successful orbital insertion, adding two functional radar imaging spacecraft to China's Earth observation network. This launch underscores ExPace's expanding launch cadence and SpaceTY's prominence in China's commercial satellite manufacturing sector. The SpaceTY-51 and SpaceTY-52 satellites will provide valuable remote sensing data for scientific research and practical applications across mainland China and neighboring regions.
