SYDNEY — A Long March 2D rocket sent a new set of experimental satellites into orbit late Sunday, capping an intense month of Chinese launch activities. The China Aerospace Science and Technology Corporation (CASC) announced complete success of the launch, revealing the payloads to be the Shiyan-30 (01) and (02) satellites. As is typical for Shiyan missions, no images and few details were released. Recent Shiyan activitiesMany Shiyan satellites operate in low Earth or near-polar orbits, though a number have headed to geosynchronous orbits, including the possible inspector satellites Shiyan-12 (01) and (02). Sunday’s launch was China’s 59th orbital launch attempt of 2025, which includes a single launch failure, being the loss of a Zhuque-2E rocket from commercial outfit Landspace in August.
