At 22:6 on November 25 Wednesday 2020, the two 150N engines of the Chang’e-5 probe worked for about 6 seconds, successfully completing the second orbit correction……As of the second orbit correction, the Chang’e-5 probe has been in orbit for about 41 hours, about 270,000 kilometers from the earth, and the probe systems are in good condition….. As The flight time of the Chang’e 5 Earth-Moon transfer segment is about 112 hours. As of the second orbit correction, it has been flying in orbit for about 41 hours, leaving about 71 hours to reach the moon… into on November 24th 2020
11月25日22时6分，嫦娥五号探测器2台150N发动机工作约6秒，顺利完成第二次轨道修正。…….截至第二次轨道修正，嫦娥五号探测器已在轨飞行约41小时，距离地球约27万公里，探测器各系统状态良好。
Previously Onto 22 hours and six minutes into on November 24th 2020, the 3000N engine of the Chang’e-5 probe worked for more than 2 seconds, successfully completed the first orbit correction, and continued to fly to the moon. As of the first orbit correction, the systems of the Chang’e-5 probe were in good condition and had been in orbit for about 17 hours, about 160,000 kilometers away from the earth.
During the flight of the Chang’e-5 probe, affected by various factors, it will produce orbit deviation. It is necessary to determine the deviation between the actual flight orbit of the probe and the designed orbit, and complete the corresponding orbit control to ensure that the probe is always flying in the proper on track.
The Chang’e-5 mission launched into orbit with high accuracy, and the orbit correction is very small this time.
11月24日22时6分，嫦娥五号探测器3000N发动机工作2秒多，顺利完成第一次轨道修正，继续飞向月球。截至第一次轨道修正时，嫦娥五号探测器各系统状态良好，已在轨飞行约17个小时，距离地球约16万公里。
嫦娥五号探测器在飞行过程中，受各种因素影响，会产生轨道偏差，需要测定探测器实际飞行轨道与设计轨道之间的偏差，完成对应的轨道控制，确保探测器始终飞行在适当的轨道上。
嫦娥五号任务发射入轨精度很高，本次轨道修正量很小。
In which On early 24th November 2020 on a very mid early morning Tuesday of 0530 Hong Kong- Beijing Time in which successfully launched the CNSA –CLEP China National Space Administration- China Lunar Exploration – Belt and Road initiative Lunar Mission ….. Launching from Wenchang Spacecraft launch center – Hainan Province – China- People’s Republic of China... the previous day the Staff of Wenchang about 18:30 on November 23, 2020, the Long March 5 Yaowu carrier rocket began to refill liquid oxygen and liquid hydrogen cryogenic propellant, and it is planned to be implemented at 4 am to 5 am on the 24th. Launch mission. This is the second applied launch of the Long March 5 series of carrier rockets, which will transport the lunar exploration project Chang’e 5 probe to the Earth-Moon transfer orbit, and implement my country’s first extraterrestrial celestial body sampling and return mission. The launch window time of the Long March 5 Yaowu rocket is based on comprehensive consideration of the earth-moon position relationship and other factors, and the best launch time is selected after orbital design…..
During the early morning crowds from all over China travelled and gathered all around the view placements locations with the best views of the launching of the Change 5 with the Long March –Chang Zheng 5 Carrier Rocket..
the Belt and Road Initiative Lunar Change5 return sample planned landing zone is Mons Rumker in Oceanus Procellarum, located in the northwest region of the near side of the Moon…… The location is a large, elevated volcanic mound 70 km in diameter that features a strong spectroscopic signature of basaltic lunar mare material.
The mission is reported to consist of four modules or elements: the lander would collect about 2 kg of samples from 2 metres below the surface and place them in an attached ascent vehicle that will be launched into lunar orbit. The ascent vehicle will make an automatic rendezvous and docking with an orbiter that would transfer the samples into a sample-return capsule for their delivery to Earth…. Change5 lunar lander equipment payload composite off…. The lander will carry landing cameras, a panoramic camera, a spectrometer to determine mineral composition, a soil gas analytical instrument, a soil composition analytical instrument, a sampling sectional thermo-detector, and a ground-penetrating radar…….. For acquiring samples, it will be equipped with a robotic arm, a rotary-percussive drill, a scoop for sampling, and separation tubes to isolate individual samples……
After the Long March 5 Yaowu carrier rocket was launched into space, it carried out four separations, including booster separation, fairing separation, primary and secondary separation, and rocket separation. The Chang’e-5 probe consists of four parts: the orbiter, the returner, the lander, and the ascender. After the earth-moon transfer, near-moon braking, and circumlunar flight, the lander and ascender combination will be combined with the orbiter and return The orbiter assembly is separated, the orbiter carries the returner to stay in orbit, and the lander carries the ascender to choose an opportunity to implement a soft landing on the lunar front preselected area, and carry out follow-up work such as automatic lunar surface sampling as planned….
According to the China National Space Administration, the Chang’e-5 mission plans to achieve three major engineering goals: First, breakthrough key technologies such as narrow window multi-orbit binding launch, automatic lunar surface sampling and packaging, lunar take-off, lunar orbital rendezvous and docking, and lunar sample storage. Improve the level of China’s aerospace technology; the second is to realize China’s first automatic sampling and return of extraterrestrial celestial bodies to promote major progress in China’s science and technology; the third is to improve the lunar exploration engineering system and accumulate important talents for China’s future manned moon landings and deep-space exploration Technology and material basis.
The scientific goals of the Chang’e-5 mission are mainly to carry out the landform area detection and geological background survey, obtain the on-site analysis data related to the lunar samples, establish the connection between the on-site exploration data and the laboratory analysis data; carry out the system of the lunar samples , Long-term laboratory research to analyse the structure, physical properties, and material composition of the lunar soil, and deepen the research on the origin and evolution of the moon.
China’s lunar exploration project is a national key science and technology special landmark project clearly defined in the “National Medium and Long-term Science and Technology Development Plan (2006-2020)”. It is a major project to promote the development of aerospace industry, promote scientific and technological progress and innovation, and improve comprehensive national strength. Strategic decision. Since the project was established and officially launched in January 2004, five missions including Chang’e 1, Chang’e 2, Chang’e 3, re-entry flight test and Chang’e 4 have been successfully implemented. This launch mission is the 353rd flight of the Long March series of carrier rockets.
