Total Eclipse Test "Chang": confronts the crisis of broken can

Keywords: Chang'e-1 Lunar Eclipse Lantern

21 is the traditional Chinese Spring Lantern Festival, is the space around the Moon Chang'e flying "a" satellite that will face the first Eclipse test. Related aerospace expert 20 stated that for the coming Lunar Eclipse, the ground had considerable preparatory work, "Chang'e 1" will be taken to include "rail adjustment" and "try to shut down some of the on-board devices" and a number of measures to deal with.

"Chang-a" satellite, the birthplace of Chinese Academy of space technology built homes 20 40 anniversary of the Chinese lunar exploration program fellow, Chief Architect of Sun jiadong "Chang'e 1" satellite Chief Designer Yepeijian fellows, two experts will be on "Chang'e 1" how to deal with the topic of the first Lunar Eclipse media interviews.

Sun jiadong, "Chang-a" satellite launch before considering the Eclipse on satellite, has launched a series of ground-based validation tests, considerable preparatory work, starting today, "Chang'e 1" engineers have arrived on the ground control centre in place, in Eclipse before the satellite to flight control.

Yepeijian said "Chang'e 1" satellite will face the first Eclipse development team has tested, ready for a lot of item response measures, including the following four aspects: first, the satellite development is done a lot of design and validation of work before the satellite into space, a series of the worst environmental compliance test, star of all devices on a simulation of the Eclipse cooling and experimental evaluation, simulation of Eclipse environment up to 6 hours; the second is on the "a" satellite Chang'e Lunar flight tracks to adjust month 27 and has been running track elevation nearly two kilometres, to shorten the satellite through Eclipse shadows of time from the original four more hours to 2 hours 25 minutes; the third is on the "Chang" No. 1 satellite control system design, supply and distribution design, data management design for targeted adjusted, shadows in the satellite into Eclipse as far as possible, let the sun shine before charging, maximum elevation satellite background temperature; the fourth is to close some of the on-board devices to be off, saving on energy star.

"Chang'e 1" first Eclipse course is expected since the Beijing time 21 10 am to 12: 40. Yepeijian said, "the Chang'e 1" the Eclipse also has a special situation, is the satellite into Eclipse shadows before, during, and after a period of time, are not in the Chinese territory and control arc coverage, through international cooperation, the European Space Agency will "Chang an" satellite through Eclipse shadows to track and control time after, but Eclipse test measures how specific effects, 21 nights can be seen. He also revealed that, in August this year, "Chang-a" satellite will once again experience the Eclipse test. World Science report (tech.)
