In December 2018, China will launch a rover to the far side of the moon. A world first and a bold bet for this country. The green light in the final preparations before the launch has just been given. Mission officials were waiting to be sure that Queqiao, the relay satellite relaying communications between Earth and the far side of the moon, would work.
China has announced that the rover of the Chang'e 4 mission will be launched in December 2018. This mission, which consists of a landing platform carrying a rover, must land on the far side of the Moon. The green light at launch was given after the satellite's flight recipe and the first weeks of use confirmed the proper operation of the Queqiao satellite, launched in May 2018, in a Halo orbit at the Lagrange 2 point of the Earth system. -Lune, about 500,000 kilometers from the Earth and 65,000 kilometers from the Moon. This satellite will relay communications from the Chang'e 4 mission rover and landing platform from the far side of the Moon.
Chang'e-4 will be launched from the Xichang launch center in the south-west of the country, aboard a Long March 3B launcher. The mission will land in or near the Von Kármán Crater in the Aitken Basin of the South Pole of the Moon. The precise location of the landing site, known to officials, has not yet been made public.

A bonus mission
Initially, exploring the dark side of the moon was not planned in China's program. In fact, the Chang'e 4 mission was intended to replace the previous one, Chang'e 3, whose objective, reached in December 2013, was to deposit on the surface of the Moon the rover Yutu ("jade rabbit" ), in case the latter has failed.
The landing gear and rover of the two missions are similar in weight and size, but the Chang'e 4 landing pad and rover have been reinforced to fit a more rugged terrain. The payload has also been adapted to the specificities of the mission on the dark side of the Moon.
Like Chang'e 3, the Chang'e 4 rover will use a panoramic camera and radar to probe the basement. It also includes an imaging spectrometer in the visible and near infrared and a Swedish instrument that will study the impact of solar winds on the lunar surface for at least three months. A small experiment in the biological field, designed by 28 Chinese universities will also be part of the mission. It involves growing Arabidopsis and potato seeds and seeing if they emit oxygen through photosynthesis. It will also check if silkworms are able to produce carbon dioxide.
