According to the Beijing Aerospace Control Center deputy Renma Yong Ping, eclipse period, the Chang'e II satellite is facing three major challenges.
The first is to maintain a long battery run alone. As the earth to the sun completely obscured, satellite can not be solar, must rely on stored battery power for a long time for the device power supply.
same time,[link widoczny dla zalogowanych], the satellite will encounter a long time,[link widoczny dla zalogowanych], \Satellite during the eclipse for a long time in the shadow of the satellite equipment will be directly facing the space temperature of minus 200 degrees Celsius environment, the satellite equipment will experience a prolonged low temperature of the test.
In addition, by the earth's rotation, moment of eclipse, the satellite during the eclipse through the domestic tracking and monitoring station can not control the satellite.
face many challenges ahead of Beijing careful design of the flight control center, starting November 30 for phase adjustment of the satellite, after more than 20 days cumulative, so that the time of eclipse of 21 satellites in the best position, ensure that the length of time in the shortest shadow.
the same time, the satellite in order to reduce the load and power consumption of the \
Another response is to adjust the satellite attitude, the solar panels facing the sun has been so that we can ensure that before entering the lunar eclipse, the satellite battery to maintain full status, but once out of the eclipse to see the sun after can also be charged immediately.
