The
Chang'e-3
probe and its moon rover separated before taking photos of each other
on the moon's surface on Sunday, marking a "complete success" of the
Chang'e-3 mission, Ma Xingrui, chief commander of the lunar program,
announced on Sunday night.
The moon rover, Yutu, took photos with
a panoramic camera at five points at a distance of 10 meters when
moving around the probe, while the probe also took pictures of the rover
with its landform camera and then sent them back to Earth, said Sun
Zezhou, chief designer of the lunar probe.
The pictures of the
moon's landscape and the probe and rover on it, carrying China's
national flag, mark the country's first soft-landing on the surface of
an extraterrestrial body.
Yutu, which traveled at 200 meters per
hour, will start a three-month research mission on the moon, examining
the moon's soil construction, landform and material composition,
according to the State Administration of Science, Technology and
Industry for National Defense.
Yutu was deployed from the probe
and tracked on the moon's surface at around 4:45 am on Sunday,
approximately seven and half hours after the successful soft-landing of
the probe.
China became the third country to do so after the US
and Soviet Union. The last such mission was made by the Soviet Union in
1976.
The probe touched down on an area named Sinus Iridum, or
the Bay of Rainbows, as planned. The landing process started at 9 pm on
Saturday and lasted for about 12 minutes, according to China Central
Television's live broadcast.
Chang'e-3's landing is the second
step of the three key stages of China's lunar program. The third step
will involve bringing samples back to Earth for closer analysis.
News
of the landing quickly made an impact on China's hugely popular social
media, topping the list of searched items, as many commented in the
style of the famous Neil Armstrong remark, "one giant leap for mankind."
The
successful soft-landing of Chang'e-3 attracted the world's attention,
as some scientists compared China's interest in the moon to that of many
other countries in exploiting resources in Antarctica, saying such
scenarios depend "entirely on the business case," the AFP reported.
Jiao
Weixin, a professor at the School of Earth and Space Sciences, Peking
University, told the Global Times on Sunday that the lunar program
mainly focuses on its scientific purpose rather than the economic
purpose, which Western media reported.
Although the moon may
have rich mineral and energy resources, such as helium-3, and China's
moon research did include examining such resources, "it is still
unrealistic for any country to profit from the moon's resources in the
near future considering the technology and cost," he said.
However, Jiao didn't rule out the possibility of developing moon resources in the future, which should be "many" years away.
During
the online interview on the program's official Weibo account, Liu
Jianzhong, a research fellow from the Institute of Geochemistry with the
Chinese Academy of Sciences, told Net users that whoever is capable of
developing the moon's resources first should reap the benefits.
China's "Jade Rabbit" separates from lander
China's first moon rover, Yutu, or Jade Rabbit,
separated from the lander early on Sunday, several hours after the
Chang'e-3 probe soft-landed on the lunar surface.
The 140 kg
six-wheeled rover touched the lunar surface at 4:35 am, leaving deep
trace on the loose lunar soil. The process was recorded by the camera on
the lander and the images were sent to the earth, according to the
Beijing Aerospace Control Center.
After the separation, the rover and lander will take photos of each other and start their own scientific explorations.
Engineers
made final checks of the environment of the landing site, the situation
of the probe and the solar incidence angle late night on Saturday and
sent signals of separation to Chang'e-3.
Yutu, atop the probe, extended its solar panel and started to drive slowly to the transfer mechanism at 3:10.
The
transfer mechanism unlocked at 4:06 with one side reaching the moon's
surface, allowing the rover to descend to the surface following a ladder
mechanism.
Chang'e-3 landed on the moon's Sinus Iridum, or the
Bay of Rainbows, at 9:11 pm Saturday, making China the third country in
the world to carry out such a rover mission after the United States and
former Soviet Union.
In ancient Chinese mythology, Yutu was the
white pet rabbit of the lunar goddess Chang'e. The name for the rover
was selected following an online poll that collected several million
votes from people around the world.
The rover, 1.5 meters long
with its two wings folded, 1 m in width and 1.1 m in height, is a highly
efficient robot controlled by the command center from the earth. It
will face challenges including temperature differences of more than 300
degrees Celsius on the moon.
Yutu will survey the moon's
geological structure and surface substances and look for natural
resources for three months, while the lander will conduct in-situ
exploration at the landing site for one year. - Xinhua

BEIJING, Dec. 14 (Xinhua) -- The moon Saturday saw a rare new visitor
-- lunar probe Chang'e-3 from China, the third country on earth which
achieved a soft landing on it after theUnited Statesand the former Soviet Union.
The success also made China the first country that conducted a soft
landing on Sinus Iridum, or the Bay of Rainbows, a lunar area that
remains unstudied and silent for hundreds of millions of years, stamping
new foot prints in the history of mankind's lunar exploration. Full story
