According to the China Manned Space Engineering Office, after entering orbit, the Tianzhou-2 cargo spacecraft successfully completed the setup of its orbital parameters. At 5:01 on May 30th, it accurately docked with the rear port of the Tianhe core module using an autonomous and rapid rendezvous and docking method; the entire process took approximately 8 hours. Tianzhou-2 carried supplies for the astronauts’ daily use, extravehicular spacesuits and equipment for the space station platform, as well as application payloads and propellant. After docking with the Tianhe core module, it entered the phase of operation as part of the combined structure, during which tasks such as propellant refueling and testing of equipment for space application projects will be carried out according to plan. It is reported that the cargo carried by the sealed compartment of the Tianzhou-2 spacecraft weighs about 4.69 tons, while the propellant weighs around 1.95 tons; the total weight of these supplies is nearly 6.64 tons. These include consumables sufficient for 3 people to use for 3 months, 2 sets of EVA suits, as well as supplies for the platform. This launch is intended to prepare living supplies for future astronauts to reside in the space station. On April 29, 2021, China successfully launched the Tianhe core module using the Long March 5 carrier rocket. The core module is 16.6 meters long, has a maximum diameter of 4.2 meters, and its launch mass is 22.5 tons. The core module features significant design advancements; the space available for astronauts to work and live amounts to 50 cubic meters, allowing three astronauts to remain on orbit for an extended period of time. The core module can be further divided into: the node module, the life support control module, and the resource module. The node module is used for docking with the Shenzhou manned spacecraft, for the docking of space experiment modules, and for astronauts to exit the spacecraft ； The life control module is used for astronauts’ work, experiments, and sleep ； The resource module provides energy support for the core module and facilitates connections with cargo spacecraft such as Tianzhou-2. After the space station enters regular operation, three astronauts will reside there as a crew on a long-term basis, with regular rotations. During the rotation period, up to 6 astronauts can work on the space station at the same time; after the handover, the previous crew returns to Earth aboard a manned spacecraft.
