Beijing (AFP) - China's troubled Jade Rabbit lunar rover, which experienced mechanical difficulties last month, has come "back to life", state media reported on Thursday.

"It came back to life! At least it is alive and so it is possible we could save it," the official Xinhua news agency quoted Pei Zhaoyu, spokesman for the lunar programme, as saying on a verified account on Sina Weibo, a Chinese equivalent of Twitter.

The probe, named Yutu or Jade Rabbit after the pet of Chang'e, the goddess of the moon in Chinese mythology, had experienced a "mechanical control abnormality" last month, provoking an outpouring of sympathy from weibo users.

Concerns were raised that the vehicle would not survive the bitter cold of the lunar night.

"The Jade Rabbit went into sleep under an abnormal status," Pei said according to Xinhua. "We initially worried that it might not be able to bear the extremely low temperatures during the lunar night."

An unverified weibo user "Jade Rabbit Lunar Rover", which has posted first-person accounts in the voice of the probe, made its first update since January, when it had declared: "Goodnight, Earth. Goodnight, humans." View gallery Fact file on China's Jade Rabbit lunar rover Fact file on China's Jade Rabbit lunar rover (AFP Photo/-)

"Hi, anybody there?" it said Thursday, prompting thousands of comments within minutes.

Xinhua has said the account is "believed to belong to space enthusiasts who have been following Yutu's journey to the moon".

The Jade Rabbit was deployed on the moon's surface on December 15, several hours after the Chang'e-3 probe landed.

The landing -- the third such soft-landing in history, and the first of its kind since the Soviet Union's mission nearly four decades ago -- was a huge source of pride in China, where millions across the country charted the rover's accomplishments.

China first sent an astronaut into space a decade ago and is the third country to complete a lunar rover mission after the United States and the former Soviet Union.

The landing was a key step forward in Beijing's ambitious military-run space programme, which include plans for a permanent orbiting station by 2020 and eventually sending a human to the moon.

The projects are seen as a symbol of China's rising global stature and technological advancement, as well as the Communist Party's success in reversing the fortunes of the once-impoverished nation.

The central government said the mission was "a milestone in the development of China's aerospace industry under the leadership of... Comrade Xi Jinping".

http://news.yahoo.com/china-39-39-jade-rabbit-39-lunar-rover-175625972.html [Junk] You can make fun of Chinese made products all you want but every country goes through the same process to industrialization. First they all make cheap #$%$ because greedy companies in the industrialized nations want to maximize profit and consumers want cheap stuff. Then as quality improves their product becomes more expensive and the manufacturing moves to another country. I remember back in the 70s everything came out of Japan was #$%$ and people made fun of them. In the 90s everything came out of Korea was #$%$ and people made fun of them. Both of these countries are making fine products now and China will eventually do the same.

Outer Space Treaty - Wikiedia

The Outer Space Treaty, formally the Treaty on Principles Governing the Activities of States in the Exploration and Use of Outer Space, including the Moon and Other Celestial Bodies, is a treaty that forms the basis of international space law. The treaty was opened for signature in the United States, the United Kingdom, and the Soviet Union on 27 January 1967, and entered into force on 10 October 1967. As of May 2013, 102 countries are states parties to the treaty, while another 27 have signed the treaty but have not completed ratification.[1][2]

Article VI of the Outer Space Treaty deals with international responsibility, stating that "the activities of non-governmental entities in outer space, including the Moon and other celestial bodies, shall require authorization and continuing supervision by the appropriate State Party to the Treaty" and that States Parties shall bear international responsibility for national space activities whether carried out by governmental or non-governmental entities.

As a result of discussions arising from Project West Ford in 1963, a consultation clause was included in Article IX of the Outer Space Treaty: "A State Party to the Treaty which has reason to believe that an activity or experiment planned by another State Party in outer space, including the Moon and other celestial bodies, would cause potentially harmful interference with activities in the peaceful exploration and use of outer space, including the Moon and other celestial bodies, may request consultation concerning the activity or experiment."[6][7]

The Moon Treaty of 1979 was meant to be the follow-up to the Outer Space Treaty, but failed to be ratified by any major space-faring nation such as those capable of orbital spaceflight.[8]

Still crazy after four decades: The case for withdrawing from the 1967 Outer Space Treaty

the 1967 Outer Space Treaty has an easy to operate escape hatch: signatory states are free to withdraw from the agreement within one year of giving notice. American, Russian, or Chinese withdrawal would reduce the treaty to irrelevance.

Surveyor 3 - Wikipedia

Surveyor 3 was the third lander of the American unmanned Surveyor program sent to explore the surface of the Moon. Launched on April 17, 1967, Surveyor 3 landed on April 20, 1967 ... bounce[d] on the lunar surface twice. ... On the third impact with the surface ... Surveyor 3 settled down to a soft landing as intended.

When the first lunar nightfall came on May 3, 1967, Surveyor 3 was shut down because its solar panels were no longer producing electricity. At the next lunar dawn (after 14 terrestrial days, or about 336 hours [My note: May 17?]), Surveyor 3 could not be reactivated, because of the extremely cold temperatures that it had experienced. This is in contrast with the Surveyor 1, which was able to be reactivated twice after lunar nights, but then never again.

[USS Liberty] Technical research ship - Wikipedia

In order to transmit intelligence information that had been gathered back to United States for further processing and analysis, these ships had a special system named Technical Research Ship Special Communications, or TRSSCOM (pronounced tress-com).[1] This Earth-Moon-Earth (EME) communications system used a special gyroscope-stabilized 16-foot parabolic antenna, which can be seen aft of the main superstructure in the accompanying photographs of the Belmont and Liberty. Radio signals were transmitted toward the moon, where they would bounce back toward the Earth and be received by a large 64-foot parabolic antenna at a Naval Communications Station in Cheltenham, Maryland (near Washington, D.C.) or Wahiawa, Hawaii. Communications could occur only when the moon was visible simultaneously at the ship's location and in Cheltenham or Wahiawa [My note: Disputable, maybe re: the Polar regions]. The gyro stabilization of the antenna kept the antenna pointed at the moon while the ship rolled and pitched on the surface of the ocean.

These ships were classified as naval auxiliaries with a hull designation of AGTR, which stands for Auxiliary, General, Technical Research. [My note: Chile reportedly the only other country with similar ship-markings, afaik] Five of these ships were built with hull numbers of 1–5. The first three ships of this type (Oxford, Georgetown, and Jamestown) were converted from World War II-era Liberty ships. The last two ships (Belmont and Liberty) were converted from Victory ships.[1] The former Liberty ships' top speed of 11 knots limited the first three AGTRs to missions of slow steaming on station with a minimum of transits.[1] Victory ships' sustained speed of 18 knots enabled Belmont to shadow Mediterranean Sea operations of the Soviet helicopter carrier Moskva in 1969.[1] All of the technical research ships were decommissioned and stricken by 1970.

One of these ships' crew received a Presidential Unit Citation for heroism in combat. The USS Liberty (AGTR-5) was attacked, severely damaged and 34 crew members killed by shelling, napalm bombing and torpedoing from Israeli jet fighter aircraft and motor torpedo boats on June 8, 1967.

The USS Jamestown (AGTR-3) was awarded a Meritorious Unit Commendation along with the USS Oxford (AGTR-1). The citation reads (in part) "For meritorious service from 1 November 1965 to 30 June 1969 while participating in combat support operations in Southeast Asia. Through research and the compilation of extremely valuable technical data, USS Jamestown and USS Oxford contributed most significantly to the overall security of the United States and other Free World forces operating in support of the Republic of Vietnam. Signed E.R. Zumwalt, Admiral, USN, Chief of Naval Operations

USS Liberty was sold for scrapping in December 1970.
