    China's Chang'e 5 mission

    China has officially announced their Chang'e 5 mission to bring back a sample from the moon will be launched in the second half of 2017

    http://news.xinhuanet.com/english/20..._135391390.htm

    China will send lunar probe Chang'e 5 to land on the moon and return with lunar samples in the second half of 2017, according to State Administration of Science, Technology and Industry for National Defense (SASTIND) on Friday.

    It will be the first time a Chinese probe to land on the moon, collect samples and return to Earth, and the third stage of China's lunar exploration endeavor, said the SASTIND.

    More information by Andrew Jones on the Chang'e 5 mission and future moon plans by China.

    http://gbtimes.com/china/china-retur...et-lunar-poles

    China will launch its Chang'e-5 probe to return samples from the Moon in 2017, and is considering future missions to the lunar polar regions.

    Chang’e-5 will launch from the Wenchang Satellite Launch Centre in the second half of next year on top of a new generational Long March 5 heavy-lift rocket, which will make its first flight around September this year.

    The news was announced by the State Administration of Science, Technology and Industry for National Defence (SASTIND) in Beijing on Friday.

    If Chang’e-5 is successful it will be the first lunar sample return since Luna 24 by the USSR in 1976, and make China only the third country to return samples from the surface.

    The complex mission involves landing and take-off from the Moon’s surface, robotic rendezvous and docking 380,000 kilometres away in lunar orbit, and returning a secured sample to Earth at the required high velocity.

    China's Chang’e-5 to Land on the Ocean of Storms in late 2017

    http://www.chinatopix.com/articles/9...-late-2017.htm

    China's Chang'e-5 surface sample return mission will land on the Moon's Ocean of Storms in the second half of 2017, revealed Wu Weiren, chief designer of China's Moon Exploration program.

    This vast lunar mare on the western edge of the near side of the Moon is the resting place of the Soviet Union's Luna 9 and Luna 13 lunar probes, as well as Surveyor 1 and Surveyor 3 from the United States. Apollo 12, the second American manned spacecraft to land on the Moon, also touched down on the Ocean of Storms, otherwise known as Oceanus Procellarum.

    Wu said the Ocean of Storms is a huge region and China wants to avoid having Chang'e-5 touch down on the landing spots of the Soviet and American spacecraft. He admitted China is looking for an "unprecedented landing site" for Chang'e-5 but wouldn't be more specific.

    China has announced Chang'e 5 will be launched late November this year.

    http://gbtimes.com/china/china-attem...ssion-november

    "China has announced that its Chang'e-5 automated Moon surface sampling and return mission will launch in late November 2017.

    The 8.2-tonne probe will launch on a Long March 5 rocket from the Wenchang Satellite Launch Centre on Hainan island, and attempt the first lunar sample return since the Soviet Union's Luna 24 mission in 1976.

    The mission will be complex, with some of the key technologies and techniques involved will also be applicable for a Chinese Mars sample return mission, planned for around 2030, as well as future crewed journeys to the lunar surface."

    From the Chinese press

    http://news.xinhuanet.com/english/20..._136004958.htm

    "The mission will be China's first automated moon surface sampling, first moon take-off, first unmanned docking in a lunar orbit about 380,000 km from earth, and first return flight in a speed close to second cosmic velocity, according to the China Aerospace Science and Technology Corporation (CASC).

    "With a weight of 8.2 tonnes, the lunar probe is comprised of four parts: an orbiter, a returner, an ascender and a lander," said Ye Peijian, one of China's leading aerospace experts and a consultant to the program."

    With China's annual parliamentary sessions starting senior space officials will be present. It is a good time for reporters to interview them on China's space plans. This year is no exception.

    http://gbtimes.com/china/change-5-sa...aunch-november

    "China's lunar probe Chang'e-5 will be delivered to the Wenchang launch site in August in preparation for its launch by a heavy-lift Long March 5 rocket in late November.

    Ye Peijian, a senior official involved in lunar exploration and attached to the China Academy of Space Technology (CAST), confirmed the move to China Central Television ahead of the country's annual parliamentary sessions in Beijing.

    The complex mission will involve a number of stages and components, involving lunar soft-landing, collecting samples, ascent from the Moon, a docking in lunar orbit, heading home and reentry into the Earth's atmosphere."

    ESA to play a critical role in China's Chang'e 5 mission.

    http://gbtimes.com/china/esa-assist-...-moon-and-back

    "Following an agreement between European Space Operations Centre (ESOC) and China, the ESA tracking network (ESTRACK) will use two ground stations to receive signals and send commands, thus providing a vital link between the Chinese spacecraft and the ground.

    Paolo Ferri, Head of the Mission Operations Department at ESOC, explains that ESTRACK support is fundamental for the success of the mission as it supports time and mission critical activities.

    Two 15m antennae will support two critical phases of the Chang’e-5 mission: the initial phase after launch, with the ground station at Kourou in French Guyana, and the final phase, in which the sample-return capsule returns to Earth, supported by the station of Maspalomas* in the Canary Islands."

    China has now indicated the landing area of Chang'e 5.

    http://mobile.shanghaidaily.com/nati.../shdaily.shtml

    "CHINA'S Chang'e 5 lunar probe is expected to land in the Mons Rumker region, and to take moon samples back to earth at the end of the year, according to a Chinese space official.

    Liu Jizhong, director of China Lunar Exploration and Space Engineering Center of China National Space Administration (CNSA), for the first time disclosed the probe landing site, an isolated volcanic formation located in the northwest part of the Moon's near side."

    Confirmation that the failure of the second LM-5 rocket will delay the launch of Chang’e-5 to next year.

    http://spacenews.com/long-march-5-fa...ation-program/

    A leading official of China’s space program confirmed Sept. 25 that the July failure of the country’s largest launch vehicle will lead to delays to upcoming lunar missions, including one to return samples.

    Tian Yulong, secretary general of the China National Space Administration, said at a press conference during the 68th International Astronautical Congress here that the investigation into the July 2 failure of the Long March 5 on its second mission was ongoing, with no updates on the cause of the failure.

    “The Long March 5 is a bigger challenge for China’s space agency,” he said. “In the future, maybe the end of the year, we will have a clear understanding of the problem.”

    Observers who followed the launch, broadcast live by Chinese television, noted a plume of gas late in the first stage burn, which suggested the failure was linked to an issue with the stage’s engines or other elements of its propulsion system. Chinese officials waited until 45 minutes after the launch to announce the launch had failed and its payload, the Shijian-18 communications satellite, failed to reach orbit.

    China is preparing to send Chang'e 5 to the moon to bring back some moon rocks next year.

    https://gbtimes.com/change-5-chinas-...n?cat=business

    When the Soviet Luna 24 mission carried out humanity's last lunar sample return mission in 1976, it did so using a direct launch from the Moon to carry 170g of Moon regolith to Earth.

    China's first attempt, Chang'e-5, which is expected to launch sometime in 2019, is going to be more complex, as a recent documentary giving rare insight into mission preparations shows.

    The four-part spacecraft includes a service module, lander, ascent unit, and a return vehicle. After the small matter of soft-landing on the Moon and collecting samples, the ascent module will blast off into lunar orbit where it will need to dock with the service module, close to 400,000 kilometers away from Earth.

    The samples will be transferred from the ascent vehicle to the reentry capsule, which itself will separate from the service module a few thousand kilometers from Earth before reentry and landing.

    While the extra complexity brings new challenges, it may well also bring experience for future lunar projects and Mars sample return missions, as well as human Moon landings in the 2030s.

    Confirmation that Chang'e-5 will launch next year. But this still depends on another successful launch of the upgraded Long March 5 this year.

    https://gbtimes.com/chinas-change-5-...9?cat=business

    China is planning to launch its ambitious lunar sample return mission, Chang'e-5, in 2019, once the required Long March 5 heavy-lift rocket has successfully returned to flight.

    Pei Zhaoyu, deputy director of the Lunar Exploration and Space Program Center of the China National Space Administration (CNSA), told a space conference marking China's Space Day on Tuesday that the complex, four-part spacecraft will liftoff next year.

    The Chang'e-5 spacecraft includes a service module, lander, ascent unit, and a return vehicle. After soft-landing on the Moon and collecting around 2 kilograms of samples, the ascent module will blast off into lunar orbit where it will need to dock with the service module, close to 400,000 kilometers away from Earth.

    The samples will be transferred from the ascent vehicle to the reentry capsule, which itself will separate from the service module a few thousand kilometres from Earth before reentry and landing in Siziwang Banner in Inner Mongolia.

    "Chang'e 5 lunar probe to get boost from AI"

    http://www.ecns.cn/news/2019-07-08/d...v5569495.shtml

    Artificial intelligence technologies will make the Chang'e 5 lunar probe smart enough in soft landings, collecting samples, ascending and docking at the lunar orbit, and returning to the Earth, according to its chief scientist.

    Ouyang Ziyuan, first chief scientist of China's lunar probe project, said on Friday at a satellite forum in Rizhao, Shandong province, that Chinese scientists have made technological breakthroughs in the 12 phases of the Chang'e 5 mission.

    The technological breakthroughs cover launching, earth-moon transfers, final braking, orbiting, descending, sampling, ascending, docking, orbiting, moon-earth transfers, separating, and reentry and recovery.

    Ouyang said the total payload of the Chang'e 5 mission will be 8.2 tons and will be launched by a new carrier rocket from the Wenchang Space Launch Center in South China's Hainan province.
