China is planning to launch a long-range carrier rocket Long March-5BY3 (Long March-5B), from the Wenchang Cosmodrome, Hainan Island. This was announced by China’s Manned Space Program Office CMSA. The rocket will carry the Wentian laboratory module to China’s Tiangong orbital base into orbit. Long March 5B will be launched at the end July.
The Wentian, weighing 23 tons, will be the largest module in Tiangong. Tiangong currently has only one base module, Tianhe. But, Wentian will soon be joining it. China will launch Mengtian, the third module, into orbit in October. Then, the national station will receive the final configuration and complete its construction.
“Wentian” wasn’t just a huge success. It has special equipment to conduct experiments and three sleeping areas. There is also a sanitary unit, a kitchen, and a sanitary unit. The Tiangong will allow for up to six cosmonauts on board the station during crew changes.
The Long March 5B is quite different to the Long March 5. The Long March 5B is noticeably different from the Long March 5. It’s a high-orbital rocket that launches spacecraft at a distance of between 30,000 and 40,000 kilometers. It was used, for example, to launch the Martian or lunar probes. Although Long March 5B cannot fly that far, it is not necessary. The national station is approximately 400km from Earth. Long March 5B is 3 meters shorter than Long March 5B. However, the diameter of Long March 5B is 5 meters. Both are equipped with four liquid boosters (side).
