Asian moonwalker “Yutu”, despite the fact that he is immobilized for a year, yet alive, and experts in the world continues to get in touch with him after 15 months spent on the moon. Engineers did not even think that he will remain at least partially operational, cooled to -180 ° C.

Lunokhod “Jade Hare” landed on the moon December 14, 2013. This is the first successful expedition to the unmanned lunar surface since the Soviet mission “Luna 24″ in 1976.
According to the lunar rover, a heavenly body consists of at least nine stone layers, reports interfax.by. A region in which the device, showed unexpected geological activity last 3.3 billion years.
According to Xiao Lun, a member of Wuhan University of Geophysical Research, these layers are formed by volcanic lava and soil, which for a long time been subjected to erosion .
This recognition success rover became today’s article in the journal Science, in which scientists reported moonwalker really important discoveries related to the turbulent past of the Moon. Helped make them powerful radar rover, translucent layers of soil to a depth record – up to 400 meters, which corresponds to the age of 3.8 billion years ago, reports gazeta.ru.
His data scientists have drawn a complete picture of the layers in the sublunary landing site apparatus Bay of Rainbows. It is believed that the crater was formed 27-80 million years ago by the powerful impact of the asteroid. Radar was able to identify as many as nine separate base layers at the landing site, which suggests a much more turbulent volcanic past of the moon than previously thought.
«The most interesting – two things. The first – that in the era of late volcanic eruptions have been much more, “- said Xiao Lun, author of the publication. Scientists believe that the upper layers of the soil at the landing site moonwalker accumulated dust and debris flown apart from the nearest impact crater. Deeper layers include traces of five consecutive outpourings of lava that flooded the area in hot period. And the long-standing such eruption happened 2.5 billion years ago. “The second surprise – that the volcanic sea consist not only of basaltic lava and pyroclastic rocks from the explosion,” – said the scientist. This means that some of the volcanoes on the moon were explosive in nature, rather than accompanied by a slow expiration of lava, as previously thought.
China Program for the Study of the Moon is divided into three stages: The launch “Chang’e-1″ (2007 ) and “Chang’e 2″ (2010). The result – drawn up a three-dimensional map of the surface of the satellite with high resolution, identify areas where it is supposed to board these vehicles. The second stage (2013) – launched the “Chang’e-3″, which is delivered to the surface of the Moon “Yutu.” The result – the expected delivery to the Earth samples of lunar rocks.
