According to the State Administration for Defence Science, Technology and Industry PRC (SASTIND), referred to by the Xinhua News Agency, January 25 in the morning during the second transfer moonwalker Yuytu (Yutu, Jade Rabbit) to sleep in the process of regime change in its control system faults were discovered. In this regard, researchers have started to scan.
More detailed information regarding the possible causes of failure, and what nodes are affected, is not currently published. According to preliminary data, malfunction caused by « complex topography of the lunar surface ».
In turn, the descent module of the Chang’e-3, whereby the Jade Rabbit was delivered to the moon, entered sleep mode safely on Friday evening, January 24. Duration of the moonlit night is about 14 Earth days. At this time, the temperature on the dark side of the moon goes down to about -180 C. At this time, the Chang’e-3 and Yuytu are in hibernation mode, and on-board equipment is stopped and heated isotopic source of energy. After the first night on the Moon Chang’e-3 surveillance conducted by an optical telescope, as well as the ultraviolet radiation of the Earth camera recorded the plasmasphere. Yuytu was busy collecting data using the panoramic camera, X-ray particle detector, radar and infrared cameras.
Yuytu Research unit was successfully delivered to the moon using the descent module of the Chang’e-3 December 13, 2013. Rover mission is designed for 3 months. From the descent module and lunar rover Chinese researchers expect to clarify and expand information on the chemical composition of the surface and the interior of the moon, its atmosphere and its impact on Earth.
