Yutu - revisited - China unveils Chang'e 4 rover to explore Moon's far side
15 August 2018
China's Moon lander and rover for the Chang'e 4 lunar probe, which is expected to land on the far side of the Moon this year, was unveiled on 15 August.
Images displayed at 15 August's press conference showed the rover was a rectangular box with two foldable solar panels and six wheels. It is 1.5 meters long, 1 meter wide and 1.1 meters high. Wu Weiren, the Chief Designer of China's lunar probe programme, said the Chang'e 4 rover largely kept the shape and conditions of its predecessor, Yutu (Jade Rabbit), China's first lunar rover for the Chang'e 3 lunar probe in 2013.

China completes 1st test on propulsion system for space experiment module
17 August 2018
Chinese researchers have successfully completed the first test of the propulsion system for the experiment module of the country's planned space station. The test consisted of eight procedures that covered all working conditions of an in-orbit experiment module. It also simulated possible errors the module may encounter in space, according to a research institute affiliated with China Aerospace Science and Technology Corporation (CASC).

China develops large aperture optical mirror with high accuracy
22 August 2018
China has developed a high accuracy four-meter-aperture optical mirror, an important tool for deep space and astronomical observation. Developed by Changchun Institute of Optics, Fine Mechanics, and Physics of the Chinese Academy of Sciences, the silicon carbide aspheric optical mirror measures 1.6 tonnes. The silicon carbide used in production provides more stability to the surface of the mirror, allowing for greater accuracy at 20 nanometers.
In addition to the mirror, the research group also developed the manufacturing equipment used for the mirror's production and owns the IP rights for the equipment.
