China’s space engineers care about reactivation, since the last model [Yutu 1] failed with its first awakening in the early 1900s. February 2014, “China’s Global Television Network (CGTN) reported today (Jan 10). Yutu 1 was the rover of China’s Chang 3 moon mission that landed on the nearby side in December 2013.
January 2, Chang & # 39 The e 4 mission the first soft landing on the lunar long side, the Rover landing duo rapped on the floor of the 110-kilometer (186-kilometer) Von Kármán crater, located in the southern Polish Aitken basin, the largest and deepest basin [China’s Chang’e 4 Farside Moon Landing in Pictures]
Yutu 2’s handler operated the rover a few days later, in a “dinner quick”, intended to protect against temporarily high moon temperatures.
by Chang 4 started.
A neutron radiation detector on board the lander, developed by Germany and a neutral atom detector on the rover, developed by sweden has both been lit, according to a statement fr n kinase National Space Administration (CNSA). Both detectors have been started and tested.
The Swedish unit, Advanced Small Analyzer for Neutrals (ASAN), will study how the solar wind interacts with the moon surface. ASAN, built in collaboration with the Chinese National Space Science Center (NSSC), is the first energetic neutral atomic sensor ever to be deployed on the moon surface. From a vantage point of only a few decimeters above the regolite surface, ASAN measures energy spectra of energetic neutral atoms derived from reflected solar windings under different solar wind conditions.
“Yes, we have successfully started using ASAN and Expect the first scientific data before mid-February,” said ASAN’s chief investigator Martin Wieser, researcher at the Space Physics Institute, at Inside Space. “This is because the rover is in a favorable position. “
ASAN is mounted on Yutu 2 rover so that the instrument can perform measurements at different locations. These data could highlight the processes responsible for the formation of water on the moon, scientists have said.

Chang’s 4’s historic landing was tricky, said Yang Yuguang, a professor at the China Aerospace Science and Industry Corporation.
“The terrain at the top of the moon is completely different from the nearby side. There are more highlands, craters and mountains and the landform is much steeper,” Yang told China’s state-owned Xinhua news agency. (A summary of the geology of the Chang 4 landing area is in this latest paper.)
Yang also emphasized the importance of a new low-frequency spectrometer worn on the Chang & # 394 mission that will lead a radio astronomical study from the other side, an ideal place to perform such work because there is no radio interference from the earth.
Chinese space managers have noted the collaboration offered by NASA, specifically orbital data from the American space agency’s Lunar Reconnaissance Orbiter (LRO). The Chinese side has provided its NASA counterparts with information on Chang & # 39; s 4 landing times and site, CNSA officials said.
LRO is slated to fly over the landing area over the next few weeks and can detect the Chang & # 39; e 4 hardware on the surface. LRO will be able to scout for the 4 landers and Yutu 2 rover at around midnight on January 31, Mark Robinson Inside Inside Space told. Robinson, from Arizona State University, is the lead researcher for LRO’s LROC camera system.

A based base station in Argentina built by China has played an important role in the mission and control of the mission. In addition, railway stations run by the European Space Agency will also offer support, according to Xinhua reports.
The Chang 4 th mission also includes a radioisotope heat source, a collaboration between Chinese and Russian researchers, to help manage the enormous temperature fluctuations on the moon’s surface. (One month’s day lasts nearly 30 days, so spacecraft on the moon is experiencing two weeks of eternal darkness followed by two weeks of sunlight.)
“International cooperation is the future of moon exploration,” Wu Weiren, chief designer of China’s moon exploration program, told Xinhua. “The participating countries would share costs, risks and achievements and learn from each other. We hope to have more international cooperation.”
