China to send over 50 spacecraft into space via over 30 launches in 2019

China is going to send more than 50 spacecraft into space via over 30 launches this year, according to the China Aerospace Science and Technology Corporation (CASC) on Tuesday.
The major missions include the third Long March-5 large carrier rocket to be launched in July, said Yang Baohua, vice president of the CASC, at a press conference.
The second Long March-5 rocket was launched from the Wenchang Space Launch Center in the southern province of Hainan on July 2, 2017, but a malfunction happened less than six minutes after its liftoff.
The cause of the failure has been found, Yang said.
If the third flight is successful, the fourth Long March-5 carrier rocket will be tasked to send the Chang'e-5 lunar probe to the moon to bring lunar samples back to Earth at the end of 2019, he said.
More details about the Chang'e-5 probe were also unveiled at the press conference.
The probe will first enter the Earth-moon transfer orbit. It will then slow near the moon to enter the lunar orbit and descend and land on a pre-selected area for ground research work, including collecting lunar samples, said Peng Jing, deputy chief designer of the probe from the China Academy of Space Technology.
After finishing its work on the moon, the ascender will rise from the lunar surface for rendezvous and docking with the orbiter flying around the moon. Then the returner will fly back to Earth via the Earth-moon transfer orbit, reenter the atmosphere and land at the Siziwang Banner (County) of Inner Mongolia Autonomous Region, Peng said.
The lunar samples taken back by the Chang'e-5 probe will be sealed in a container and sent to labs for further analysis and research, he added.
The probe can be divided into 15 sub-systems, including structure, thermal control, antenna, sample collecting and sealing and propulsion. It is composed of an orbiter, a returner, a lander and an ascender.
In addition, joint tests and exercises will be carried out in the Wenchang Space Launch Center at the end of 2019 to make preparations for the maiden flight of the Long March-5B, which will help lay the groundwork for the construction of the space station, said Shang Zhi, director of the Department of Space under CASC.
A test version of the Long March-5B carrier rocket, which will serve China's manned space exploration mission, is now under development, and the research and development of the core module of the country's space station have carried on as planned, Shang said.
The Long March-5B rocket, with a low-Earth orbit carrying capacity greater than 22 tonnes, will be used to launch the core module and experiment modules of China's space station in the future.
China will also send 10 satellites to join the BeiDou Navigation Satellite System (BDS) through seven separate launches this year, which will help complete the BDS global network by 2020, Shang said.
According to the Blue Book of China Aerospace Science and Technology Activities released at the press conference, a total of 18 BeiDou satellites were launched in 2018, marking the completion of the BDS-3 primary system. The navigation system has started to provide global service.
China will also launch a new Earth observation satellite, Gaofen-7, and witness its first sea-launch by the Long March-11 rocket, Shang added.

China to deepen lunar exploration: space expert
Beijing (XNA) Jan 14, 2019
As the Chang'e-4 probe made the first-ever soft landing on the far side of the moon, a senior Chinese space expert said China will deepen its lunar exploration and venture further into the unknown. China's current lunar program includes three phases: orbiting, landing, and returning. The first two phases have been accomplished, and the next step is to launch the Chang'e-5 probe to collect 2 kg of samples and bring them back to the earth, said Wu Weiren, an academician of the Chinese Academy of Eng ... read more
