Chang'e - CNSA lunar orbiter

EuroLauncher · 2006-01-07 19:39:59

The Chinese government has all along regarded the space industry as an integral part of the state's comprehensive development strategy. China's CASC is a large enterprise that builds many different series of satellites, CAST said some of the satellites such as a polar-orbiting Sun-synchronous weather satellite FY-1D and the oceanorgaphic satellite Haiyang-1 are being constructed, while the Chinese are also doing some work with Russia, joint missions with ESA to explore the magnetosphere using the Double-Star craft and have offered co-operative ventures with the United States.
China has set up three launching sites - in Jiuquan, Xichang and Taiyuan - which have successfully accomplished various kinds of test flights of launching vehicles and launches of a variety of satellites and experimental spacecraft. On March 3 1971, a LM-1 vehicle was also used to launch China's first Shijian scientific experiment satellite, which was operating in space for 8 years and obtained scientific data in space. Shi Jian 5, the SJ-5 satellite was launched into an 870 km similar circle orbit on May 10, 1999. The satellite was designed to operate normally in orbit for three months and carry out a two-layer scientific experiment in microgravity environment, new technology demonstration experiment, and the detection and countermeasure research of the single particle. According to the preset sequence the SJ-5 was launched, tested in orbit, transferred, managed for a long time and tested for lifetime. China plans more Dongfanghong communications satellites and is also lauching Fengyun weather satellites, and Ziyuan remote sensing Earth resource satellites, and plans some more Beidou navigation satellites.

Manufacturing of the carrier rocket and satellite for China's first lunar expedition has kicked off, according to the State Commission of Space, Technology and Industry for National Defence.
Related facilities including the launch and ground application systems have begun testing, said spokesman Jin Zhuanglong at a press briefing.
China is scheduled to send its first satellite to the moon in April 2007 from the Xichang Satellite Launch Centre in Southwest China's Sichuan Province, in a one-year lunar mission dubbed Chang'e Project.

Chang'e 1 is planned to be the first of a series of Chinese missions to the Moon. The spacecraft will launch in late 2007 on a CZ-3A booster and orbit the Moon for a year to test the technology for future missions and to study the lunar environment and surface regolith. The orbiter is based on the DFH-3 Comsat bus and will have a mass of roughly 2000 kg, 150 kg of which will be the scientific payload.
China's plans to send a spacecraft around the moon have reached a new stage, with the unmanned orbiter and rocket entering production and testing, China's top aerospace official said on Thursday.
Luan Enjie, commander of China's Round The Moon project, said the Chang'e 1 Lunar Orbiter and a launch rocket are being assembled and tested, and the launch site and command system are also taking shape, the official Xinhua News Agency reported. Luan said the craft is still on schedule to be launched in 2007. The payload will include a stereo camera system to map the lunar surface, an altimeter to measure the distance between the spacecraft and the surface, a gamma/X-ray spectrometer to study the overall composition and radioactive components of the Moon, a microwave radiometer to map the thickness of the lunar regolith, and a system of space environment monitors to collect data on the solar wind and near-lunar region. The Chang'e program is named for a Chinese legend about a young fairy who flies to the Moon.

are they preparing for a manned mission ?

EuroLauncher · 2006-03-07 13:57:00

GUIYANG, March 4 (Xinhuanet) -- China's moon-probe program will pave the way for the country's high-tech breakthroughs and innovation and will help train a large group of top scientists, a senior space scientist said here Saturday.

Ouyang Ziyuan, an academician of Chinese Academy of Sciences and also the country's chief scientist on the moon-probe program, said at a symposium Saturday that China will benefit from its probe of the moon, particularly in the field of scientific innovation.
http://news.xinhuanet.com/english/2006- … 258055.htm
The moon probe demands lots of advanced technologies in the aspects of rocket communications, observing and control, remote sensing and manufacturing of lots of complicated instruments, the scientist said.

He said the research progress of the all the above mentioned technologies will also drive the development of some fundamental science research which will ultimately upgrade country's science and technology.

Nuclear-powered lunar rover
http://www.engadget.com/2007/04/03/chin … nar-rover/

Perhaps the most interesting part of this design is its dual-mode power system, which consists of the standard solar cell array as well as a nuclear power source, allowing the rover to operate continuously and in areas that go long periods without sunlight. No word yet on when exactly the Chinese will pick the winning rover, but expect whichever model emerges victorious to head skyward sometime in 2012.

Chang'e I enters Earth-moon transfer orbit - 31 Oct 2007

CHINA'S first lunar probe Chang'e I completed its fourth orbital transfer this evening and entered the Earth-moon transfer orbit, a critical point that may determine whether the satellite can fly to the moon successfully.
The orbiter transferred to a 114-hour Earth-moon orbit at 5:15pm today with an apogee of more than 370,000 km, up from the former 120,000 km, which was one more step forward in its 1,580,000-kilometer journey to the moon.
The orbiter, named after the Chinese goddess who, according to legend, flew to the moon, has broken the country's space exploration record by traveling farther from the planet than any other domestic orbiter after it roamed to the apogee of 120,000 km at 5:40pm yesterday.
The satellite opened its ultraviolet image sensors about 7am yesterday and began work collecting information on the Earth, the report said.
The images will be transmitted back to the Earth when it enters lunar orbit early next week, the report said.
The orbiter transferred to a 48-hour orbit at 6:01pm on Monday after completing its second orbital transfer last Friday.
Chang'e I blasted off on a Long March3A carrier rocket at 6:05pm last Wednesday from the Xichang Satellite Launch Center in the southwestern province of Sichuan, marking the first step of China's three-stage moon mission, which will lead to a moon landing and launch of a moon rover around 2012.
The 2,300-kg satellite is expected to arrive in the moon's orbit next Monday with eight probing facilities, including a stereo camera and interferometer, an imager and gamma/x-ray spectrometer, a laser altimeter, a microwave detector, a high energy solar particle detector and a low energy ion detector, Xinhua said.

China denies lunar probe photos were faked

BEIJING, Dec 3 (AFP) Dec 03, 2007
China has denied allegations by Internet users that a photo taken by its first lunar probe was copied from previous images taken by NASA, state media reported Monday.
China last week published the first photo of the moon taken by the Chang'e I orbiter, which was launched on October 24, with Premier Wen Jiabao hailing the image as evidence of the nation's rise as a space and technological power.
However, some Chinese Web users have suggested the photo, showing a crater-pocked section of the lunar surface, was strikingly similar to one taken in 2005 by the US space agency, the Beijing News reported.
But the paper quoted Ouyang Ziyuan, one of the chief scientists for the mission, as dismissing the claims.
"China's first moon photo is absolutely not a fake," he said.
A comparison of the pictures in the newspaper showed they were taken of the same area.
But in one section only a single small crater appears in the American photo, while the Chang'e image shows two.
Ouyang was quoted as saying that might be due to a lower resolution of the US image.
However, the US photo reproduced in the paper appeared to be sharper than the Chinese one.

Curious story, and there was no US probe in 2005, perhaps they mean ESA's SMART-1 lunar orbiter.

You Have Edited the Thread Title to "In Lunar Orbit ?? "

Yeah there's always the wacky possibility that China photo shopped it and NASA is covering up evidence of alien life on Mars

I never figured you as a person who would buy into tin-foil head conspiracies

Well spotted!

Not even Yang has updated this topic with a confirmation of orbit or the one and only image, maybe that news article will provoke someone

(remember, to be safe always use triple layer foil)

Three months since launch and very little news. Were more photos released or just the one?

Chang'e-1 makes precise flight

January 29, 2008
Data from the Beijing Space Flight Control Center show that on the 28th, Chang'e-1's satellite equipment is working properly. It is in orbit 200 km away from the Moon, with orbital accuracy only slightly different (.0003) from the theoretical figure.
In addition, Director Tang Ge, from Beijing Space Flight Control Center, said in an interview on January 28th that the tracking data from Chang'e-1 indicate that China's deep space exploration flight control capabilities have made a breakthrough.
The Moon is a very irregular sphere, and satellites in orbit around different locations of the Moon experience relatively different gravitational pulls. A chapter has been written on China's flight control of lunar exploration satellites where there was once a blank page.

At last an update!

All sounds ok, but what is an orbital accuracy of .0003?
