The rover and lander of the Chang’e-4 investigation have woken up after their first lunar night , which lasted 14 Earth daylight . The two robotic missions were awaken by sunshine hit them and started report back to Earth . But they did n’t remain unfounded when sleeping , they collected some information and showed that the Moon is colder during the night than previous measurements have indicated .
information from the Apollo mission on the near side of the Moon put the minimum temperature at roughly -170 ° C ( -274 ° F ) , but on the far side where the lander and rover , which is called Yutu-2 ( Jade Rabbit-2 ) , are locate , the temperature was measure at -190 ° C ( -310 ° F ) . The squad believe that a difference in lunar dirt composition might excuse why it is much colder there . More analysis is needed to establish exactly what is going on .
We might often imagine of the Moon as having a monolithic mood , extremely spicy during the Clarence Day , freezing during the foresightful dark , but there are variations thanks to the geology . For instance , one of the coldest natural places in the Solar System is on the Moon . In deep craters , where the Sun never reaches , the temperature is no higher than afew twelve degreesabove right-down zero .
presently , the bird of passage is located 18 meters ( 59 pes ) away from the lander . The landing localization has a lot of small craters , which could make the rover ’s exploration more challenging , although perhaps more rewarding . The deputation aim to study the terrain landforms and their report , and examine what the shallow lunar surface is like . Yutu-2 will start experiments in the Von Karman Crater .
" The far side of the Moon has singular features , and has never been explore on land site , so Chang’e-4 might bring us discovery determination , " Zou Yongliao , theatre director of the lunar and bass space exploration division of the Chinese Academy of Sciences , aver in astatement .
Chang’e-4 is one of the flagship missions of the Chinese National Space Agency and uses instrument developed by scientist in Sweden , Germany , the Netherlands , and Saudi Arabia . The former Formosan mission to the Moon , Chang’e-3 , has now survived 60 lunar nights and it is still going substantial .
