The  Chang'e-1  lunar orbiter has successfully survived the Earth eclipsing the Sun,  and blocking  its supply of solar energy.  
From about 10 a.m., the satellite was  hidden from direct sunlight and lost the contact from the Earth for about four hours; the orbiter returning to the sunlight and  resumed contact at about 2:10 p.m.
During the eclipse the satellite managed to  lose only 40 percent of its power storage.
According to  Ye Peijian, chief commander and designer in charge of the satellite system, the control centre had raised the orbit of the satellite to shortened the time it was not in direct sunlight by almost one hour and a half.

According to Chinese officials ,  the  Chang'e-1 lunar probe has successfully captured pictures of the moon's polar  regions.
The Chinese Commission of Science, Technology and Industry for National Defence released  a picture of the moon's polar areas, on Thursday.
Ground controllers on January  4 adjusted  the  camera  aboard the satellite so that it could image  areas above 70 degrees north or south latitude.    This allowed the  first-ever  picture of those regions  on the moon to be taken.

"We have obtained good quality pictures" - spokesman Pei Zhaoyu,  China National Space Administration (CNSA).

The probe also raised  its orbit by nearly two kilometres on Sunday night to avoid a power shortage during a moon eclipse on Feb. 21.

Some dogged sleuthing by a fellow space blogger has tracked down the truth behind the controversial first photo from China's moon orbiter.
In the week since the picture was released amid much fanfare in Beijing, there have been widespread rumours that the photo was a fake, copied from an old picture collected by a U.S. space probe.
The good news for the Chinese is that Planetary Society blogger Emily Lakdawalla's clears them of outright fakery. The bad news is, she found evidence that the photo was badly retouched for public release....
Lakdawalla found that a mistake was apparently made in stitching together the 19 strips of imagery to produce the finished picture - and that Chinese officials unknowingly pointed out that mistake as they defended the photo's veracity.

Ed ~ The new crater was always in doubt because it was not bright enough.

China's lunar probe pictures taken last week, left, and the 2005 NASA pictures, right. The extra hole in the Chinese pictures could suggest it was hit by an extra meteorite.

According to Ouyang Ziyuan, a  leading scientist in the Chang'e program,  scientists and astronomy enthusiasts from all over the China all have free access to data sent back from China's first lunar orbiter Chang'e I.

"The money used for the Chang'e project comes from the taxpayers and, therefore, the data should also be made public. Any scientist or astronomy lover can apply to the state in accordance with certain procedures to obtain data he needs"

Ouyang Ziyuan, professor at the Chinese Academy of Sciences (CAS) and chief scientist of the lunar exploration program, said  that  the scientific instruments on board Chang'e I  are all operating and  currently sending back 3 trillion of data per second. The total data volume will reach 28 Terabytes  next year.(1 Terabyte is equivalent to 1,000 Gigabytes)
