China’s Chang’e-4 spacecraft lowered its orbit around the moon on Sunday in preparation for a landing on the lunar far side, Xinhua reports. The mission consists of a stationary lander and a rover.
The probe has entered an elliptical lunar orbit, with the perilune at about 15 km and the apolune at about 100 km, at 8:55 a.m. Beijing Time, said CNSA.
Since the Chang’e-4 entered the lunar orbit on Dec. 12, the ground control center in Beijing has trimmed the probe’s orbit twice and tested the communication link between the probe and the relay satellite Queqiao, or Magpie Bridge, which is operating in the halo orbit around the second Lagrangian (L2) point of the earth-moon system….
The control center will choose a proper time to land the probe on the far side of the moon, according to CNSA.

On this day, he also had the opportunity to speak with Wang Zhigang, Minister of Science and Technology, Zhang Kejian, CNSA Administrator, and Wang Zhenyu, head of the CNSA’s Office of International Cooperation. Chinese Academy of Sciences.
HONG KONG (PolyU PR) — The Hong Kong Polytechnic University (PolyU) proudly supports the nation’s current lunar exploration, Chang’e-4 lunar probe, with advanced technologies, namely the design and development of an advanced Camera Pointing System, and an innovative lunar topographic mapping and geomorphological analysis technique in landing site charaterisation for the space craft.
Video Caption: China’s Chang’e-4 lunar mission was launched by a Long March-3B rocket from the Xichang Satellite Launch Center, Sichuan Province, southwest China, on 7 December 2018, at 18:23 UTC (8 December at 02:23 local time). The Chang’e-4 (嫦娥四号) lunar mission (lander and rover) is scheduled to land in the Aitken crater, located in the Aitken Basin, in the South Pole region on the far side of the Moon.
Chinese officials report the Chang’e-4 relay satellite has entered its planned orbit, where it will await the year-end launch of the program’s lunar lander and rover bound for the far side of the moon.
The satellite, named Queqiao (Magpie Bridge) and launched on May 21, entered the Halo orbit around the second Lagrangian (L2) point of the Earth-Moon system, about 65,000 km from the Moon, at 11:06 a.m. Thursday after a journey of more than 20 days.
“The satellite is the world’s first communication satellite operating in that orbit, and will lay the foundation for the Chang’e-4, which is expected to become the world’s first soft-landing, roving probe on the far side of the Moon,” said Zhang Hongtai, president of the China Academy of Space Technology (CAST)….
He said the Halo orbit was a three-dimensional irregular curve. It is extremely difficult and complex to maintain the satellite in orbit.
“If there is a tiny disturbance, such as gravitational disturbance from other planets or the Sun, the satellite will leave orbit. The orbit period is about 14 days. According to our current plan, we will conduct orbit maintenance every seven days,” Zhang said.
TOKYO (ROSCOSMOS PR) — On March 3, 2018, the Roscosmos State Corporation and the Chinese National Space Administration, in the framework of the International Space Development Forum (ISEF) in Tokyo, signed an agreement on intentions for cooperation in the field of exploration of the Moon and deep space, and the creation of a Data Center on lunar projects.
The sides expressed their readiness to consider the possibility of cooperation in the implementation of the Russian mission to launch the orbital spacecraft Luna-Resurs-1 (Luna-26) in 2022, as well as the planned Chinese mission for landing in the region of the south pole of the Moon in 2023. The document was signed by the general director of Roskosmos state corporation Igor Komarov and the deputy head of the Chinese national space administration Y. Yanhua.

YANTAI, China (ESA PR) — ESA astronauts Samantha Cristoforetti and Matthias Maurer joined 16 Chinese astronauts earlier this month for nine days of sea survival training off China’s coastal city of Yantai. The ultimate goal is for ESA to establish a long term cooperation with China and ESA astronauts to fly on China’s space station.
The size of the global space industry, which combines satellite services and ground equipment, government space budgets, and global navigation satellite services (GNSS) equipment, is estimated to be about $324 billion. At $95 billion in revenues, or about 29 percent, satellite television represents the largest segment of activity. Following this is government space budgets at $76 billion, or 24 percent, and services enabled by GNSS represent, about $76 billion in revenues. Commercial satellite remote sensing companies generated on $1.6 billion in revenues, but the value added services enabled by these companies is believed to be magnitudes larger. Because remote sensing value added services includes imagery and data analytics from other sources beyond space-based platforms, only the satellite remote sensing component is included in the global space industry total.
DUBAI, UAE (UAE Space Agency PR) — The UAE has signed a memorandum of understanding with the People’s Republic of China concerning defining a framework for collaboration in studies and development in space science, as well as the peaceful exploration of outer space.
