e capsule and the Wentian and Mengtian lab capsules. The station could be enlarged to 180 tonnes if required for scientific research. It could accommodate three to six astronauts and was designed to last at least 10 years, said Zhou, but this could be prolonged through in-orbit maintenance. The station would stay in orbit at an altitude of about 393 kilometers. A capsule flying in the same orbit would hold a large optical telescope with a field of view 200 times larger than that of the Hubble space telescope. It could dock with the space station if necessary. While smaller than the International Space Station (ISS), the construction and materials supply of China's space station would be close to the ISS, and its technologies in information, energy and dynamic systems were more advanced. Its main purpose would be cutting-edge scientific research, including space medicine, space life sciences and biotechnology, material sciences, microgravity basic physics, astronomy and astrophysics.
