The China Academy of Launch Vehicle Technology (CALVT) has developed a parachute-controlled descent system that could reduce the risks and costs associated with rocket debris falling to Earth after a launch. The system was tested during a launch of a Long March 3B rocket on 17 May. The parachute was deployed at a predetermined altitude following the separation of the booster from the core stage of the rocket, enabling the booster to follow a planned descent path and land in a specific area that was 20% smaller than prior debris landing zones. The system includes a controllable parafoil and an integrated navigation and positioning system.
