China steps up launch cadence with 4 missions in 3 days; Kuaizhou-11 launch signal follows silence while Shijian-31 space-enviro
China completed four launches in three days, including a mission delivering Shijian-31, an experimental satellite focused on detecting the space environment. After a Kuaizhou-11 solid-rocket liftoff, prolonged “silence” followed, raising questions about the mission’s status. Other reports cite a common high-orbit delivery profile using a Long March 3B/E.
