A transport must come home

Shenzhou’s role includes taking people to orbital destinations and returning them to Earth. A later station flight is part of a transportation system, not merely another launch. Keeping the return vehicle ready matters while the crew conducts research elsewhere aboard the station.

A return sequence changes the spacecraft’s orbit, separates modules and brings the protected capsule through the atmosphere. Parachute descent occurs after the high-speed entry phase. Search and recovery teams then locate the capsule and assist its occupants. These phases solve different problems and cannot substitute for one another.

In a fictional landing exercise, the capsule reaches the planned area but the recovery team cannot communicate with it. Touchdown has occurred; recovery still needs attention. After a long stay in orbit, medical support, physical assistance and transport are part of bringing the crew home. Evaluate the operation through handover to the ground team.
