The landing site system for the manned spaceflight is quite different from other kinds of space missions. Here's some of the details.

The system is composed of five subsystems. They are the primary and secondary landing site subsystem, the land emergency rescue subsystem, the marine emergency rescue subsystem, the telecommunications subsystem and the medical monitoring and guarantee subsystem.

The landing site system has four main tasks.

It is used to track and measure the returning trajectory of the re-entry module before and after it enters the blackout area, to search and collect messages from the capsule and accurately send remote-control instructions as required.

It searches for the re-entry module, helps the astronauts get out of the capsule, provides medical monitoring and first aid, and transports the re-entry module to its designated place.

It ensures telecommunications between the primary landing site and the Beijing Aerospace Command and Control Center, and the astronauts as well.

The system is also used to provide information about the atmosphere below the altitude of 25 kilometers above the primary landing site.

China created a compact and efficient landing system with powerful functions for the manned space project. The system will help perform the third space retrieval and rescue operation following the US and Russia.

Under the design principle of optimized system, comprehensive utilization, ensuring priorities, and technological innovations, Chinese scientists have rolled out a manned space retrieval and rescue system, covering pre-launch, ascending and returning phases,and landing arrangements.

To ensure astronauts' safe return to land, scientists have found solutions to a range of difficulties, including tracking in the dark obstacle zone, high sea rescue, and communication capability for fast moving truck based satellite telecommunication stations.

In addition, scientists developed a medical supporting system tailored to the needs of astronauts, together with a set of rescue facilities and associated working procedures.

The new landing system makes prompt recovery of the return capsule possible, with capability for an emergency return in ascending phase, marine rescue, emergency return of in-orbit capsule, and worldwide rescue.
