First rover? The other rovers sent to Mars are made in China. The parts are made in China. Thats how embarrassing it is. I mean even now the U.S. is sending rovers made by China to Mars. So I'm laughing okay?

Well, bad news guys...
China’s maiden moon rover ‘Yutu’, beloved by millions, has been lost.
RIP!
The sad, breaking news was just reported today in an ultra brief dispatch by the English language version of Chinadaily – with the headline “Loss of lunar rover.”
Yutu apparently froze to death and failed to wake up and communicate with China’s mission controllers in Beijing on Monday, Feb. 10, when daylight returned to the rovers lunar landing site at Mare Imbrium at the start of what would have been Lunar Day 3.
“China’s first lunar rover, Yutu, could not be restored to full function on Monday [Feb. 10] as expected,” wrote Chinadaily.com.
Note: This story will be updated as further details emerge.

Yutu has touched the hearts of countless Earthlings since the history making landing on the Moon atop the Chang’e-3 lander two month ago on Dec. 14, 2013, but now will never see another Earthrise.
Although definitive word about the Chang’e-3 lander has not yet been announced, it is expected to survive and has a 1 year design lifetime.
The tragic Yutu news was not unexpected however, after Chinese space officials disclosed that the rover “experienced a mechanical control abnormality” two weeks ago, just as her 2nd lunar night was to begin, according to a report by China’s official government newspaper, The People’s Daily.
“Yutu experienced mechanical problems on Jan 25 and has been unable to function since then,” wrote Chinadaily.com.

Each lunar day and night lasts for alternating periods of 14 Earth days.
The Yutu rover and Chang’e-3 mothership lander had just finished sleeping through the terribly frigid two week long lunar night since they entered their second hibernation period on Jan. 24th and 25th respectively, and Chinese space engineers had hoped to reawaken both probes in the past few days.
No communications are possible during the period of nighttime dormancy.
See our artistic impression of Earthrise over Yutu – above. It combines real images of the Moon’s surface terrain with an intentionally enlarged photo of Earth – all snapped by the Chang’e-3 lander – as a homage to the mission.
Yutu, which translates as ‘Jade Rabbit’ is named after the rabbit in Chinese mythology that lives on the Moon as a pet of the Moon goddess Chang’e.
The piggybacked pair of Chinese probes safely touched down on the Moon at Mare Imbrium near the Bay of Rainbows on Dec. 14, 2013.

Apparently one of Yutu’s solar panels did not fold back properly over the instrument laden mast after it was lowered to a horizontal position into a warmed electronics box where it is shielded and insulated from the extremely frigid lunar night time temperatures.
Such a malfunction would spell doom for the fragile electronic and computer components in the unprotected mast mounted instruments and systems, including the color and navigation cameras and the high gain antenna.
During each 14 Earth-day long night, the Moon’s temperatures plunge dramatically to below minus 180 Celsius, or minus 292 degrees Fahrenheit.
‘Jade Rabbit’ had departed the landing site forever, and was journeying southwards as the incident occurred – about six weeks into its planned 3 month long moon roving expedition.
The 140 kg Yutu robot drove off a pair of ramps and onto the moon seven hours after the Dec. 14, 2013 touchdown.
The 1200 kg stationary lander is expected to return science data about the Moon and telescopic observations of the Earth and celestial objects for at least one year.
Chang’e-3 and Yutu landed on a thick deposit of volcanic material.

They were designed to conduct their science investigations and work independently of one another.
China can be proud of its magnificent space flight accomplishment.
Chang’e-3 was the first spacecraft from Earth to soft land on the Moon in nearly four decades since the touchdown of the Soviet Union’s Luna 24 sample return spacecraft back in 1976.
America’s last visit to the Moon’s surface occurred with the manned Apollo 17 landing mission – crewed by astronauts Gene Cernan and Harrison ‘Jack’ Schmitt , who coincidentally ascended from the lunar soil on Dec. 14, 1972 – exactly 41 years before Chang’e-3.
China’s follow on Chang’e-4 Moon lander is due to blastoff in 2015.
Surely the science and engineering team will incorporate valuable lessons learned.
China is only the 3rd country in the world to successfully soft land a spacecraft on Earth’s nearest neighbor after the United States and the Soviet Union.

Not yet. From CCTV, Yutu may suffer some damage of some parts. It may still function and the only thing is it will not able conduct the originated all experiment.

in a weird way this good. China always report this is done great that's done great, which doesn't make me think they are great, just that the difficulties are not that high.
People fail when they go into high risk situations, that's just the way it is. Nobody fails at walking, but everyone can do it and it's not special.
If we are failing that just means we are finally at a stage where we are going into new fields.

please take back the false news.
Yutu is alive. Check out latest yahoo world news.

China's lunar rover "wakes up": spokesman
English.news.cn 2014-02-13 11:05:41
BEIJING, Feb. 13 (Xinhua) -- China's moon rover Yutu is awake after its troubled dormancy but experts are still trying to find out the cause of its abnormality, a spokesman with the country's lunar probe program said on Thursday.
"Yutu has come back to life," said Pei Zhaoyu, the spokesman.
Pei said the moon rover, named after the pet of a lunar goddess in ancient Chinese mythology, has now been restored to its normal signal reception function. But experts are still working to verify the cause of its mechanical control abnormality.
The problem emerged before Yutu entered its second dormancy on the moon on Jan. 25 as the lunar night fell.
"Yutu went to sleep under an abnormal status," Pei said, adding that experts were concerned that it might not be able to survive the extremely low temperatures during the lunar night.
"The rover stands a chance of being saved now that it is still alive," he said.
On Sina Weibo, China's Twitter, user "Yutu Lunar Rover", which has followed the developments of the rover mission in a first-person account, posted its first update since the abnormality.
"Hi, anybody there?" it asked in a post, which immediately attracted tens of thousands of comments.
Many Chinese Internet users said they were moved to hear that their "cute rabbit" had "come back to life", and some said the rover was a "foodie" waking up for rice dumplings, a must-have delicacy for China's Lantern Festival that falls on Friday.

Chang'e-2 lunar probe travels 70 mln km
English.news.cn 2014-02-14 20:47:00
BEIJING, Feb. 14 (Xinhua) -- China's second lunar probe, Chang'e-2, has traveled more than 70 million km into deep space in good condition, so far the longest voyage of a Chinese spacecraft, a senior engineer said Friday.
Chang'e-2 was launched on Oct. 1, 2010 to verify crucial technologies for Chang'e-3. It set off from its moon orbit for outer space in June 2011 after finishing all of its tasks.
Chang'e-2 is expected to travel as far as 300 million km from the earth, after which it will return to perigee of about 7 million km from the earth around 2029, said Zhou Jianliang, chief engineer of the Beijing Aerospace Control Center.
The probe will reach 100 million km from Earth in July of this year.
The control center has made many breakthroughs in fuel use and orbital decay technologies, which will boost China's future deep space exploration, Zhou said.

A visual concept of Chang'er 5
Credit: tech.qq.com
Chang'er 5 will be launched approximately in 2017
The project will involve landing, exploring and returning home with moon rock and soil samples. The manoevres will be unmanned.
There will be a rendevouz and docking procedure in the Lunar orbit before returning home
A test capsule will be launched this year!
