The Chinese probe Chang’e-4 is a communication from the Chinese state news Agency Xinhua to 3.26 PM CET on the far side of the moon – a world premiere. They landed at the Aitken crater near the lunar South pole. There you will explore the Geology of the Region and biological experiments.
Although it had been in the last few years, several missions to the moon; most of the probes circled the moon only, on flew over or collided. The last Moon landing with people took place in 1972 by the Apollo 17 Mission. The of the earth permanently facing away from the side of the moon remained so far from the people, and its technology intact.
In the year of 2013 was the first Chinese space probe Chang’e-3 on the moon and put a Rover, a robot vehicle. This, however, remained on the earth-facing side. A launcher brought on a 7. December, the probe, Chang’e-4, which landed for the first time on the back. With the moon mission, China wants to prove that the country can make great advances in science.

the success of The Mission was not sure at first. Especially the landing manoeuvre is considered to be difficult, because the terrain on the moon’s backside is not as flat as the front. The communication is difficult, because there was no direct radio link. Therefore, China was in may the transmission of satellite Queqiao (English: bridge of magpies) in Position. This can also be from the radio shadow signals sent to The satellite reflects the data and directs them to the earth.
next. the Rover of the Chang’e-4 to the nearby Von-Kármán crater, the shock is probably caused by a Comet It has a diameter of over 2,500 km and is 13 km deep – the deepest, and oldest craters on the moon, said physicist Andrew Coates with the BBC. The investigation should give more detailed information about the different layers of the moon. The Rover is equipped with a panoramic camera and various measuring devices.
experiments with low radio frequencies are Planned. Without the earth’s atmosphere and other interference, astronomers are able to absorb in the silence of the universe signals better, and they hope for new insights into the origin of the stars.

Also has loaded the probe, Chang’e-4 seed. In order for the Team behind it wants to check, whether growing vegetables in a closed environment at low gravity.
On Board of the Kiel Christian-Albrechts-University of developed radiation measuring device. The Kiel Experiment should be measured at least for a year the radiation and the water content of the soil and send data back to earth. The results should help future manned missions to the moon to prepare.
