Chang Space Spacecraft comes into Orbit Lunar before the 1st Coast



HELSINKI – Congratulations to China Chang 4 completely and rush successfully on Wednesday (December 12) following a four and a half flight to the moon.

The spacecraft entered an elliptical polar orbit with a 62 mile (100km) per cent at 3:45 a.m. EST (0845 GMT) December 12 following burning orbit inserted lunch.

The changing space space of the space space broke at 80 miles (129 km) away from the moon after issuing an order by the Beijing Aerospace Control and Control Center (BACC) at 3:39 a.m. EST (0839 GMT). [China’s Chang’e 4 Moon Far Side Mission in Pictures]

The China Lunar Search Project (CLEP) announced the success of the crucial movement within minutes and confirmed that the spacecraft worked well and will start preparations for exchanging satellite communication tests and refining its orbit.

Chang 4 was launched by the March 3B Ship carrier of the Xichang Satellite Launch Center, southwestern China, at 1:23 p.m. EST (1823 GMT) on December 7 for a 110 hour journey to the moon.

Three trajectory correction movements had been planned for the lunchtime transfer period, but only one needed, which was held on December 9, with the first and final view unnecessary and therefore canceled .

Including landing and blast, the spacecraft will try to land the first soft on the far side of the moon – tidal lock will never face Earth – early 2019.

Science charging cameras and loads have science pay cameras and payments to support the geographer and roaming to analyze the surface geology of the pictures and interfaces, solar wind interactions and maintain low frequency radio comments in the radio- Unique quiet at the far side of the moon.

Communication with the spacecraft will be facilitated by the Q & A exchange satellite; which was launched in May and then inserted into an orbit around the second Lagrange Moon point, about 40,000 to 53,000 miles (65,000 to 85,000 km) beyond the moon.

The landing will target candidate landing sites in the South Pole-Aitken (SPA) Basin, with the selected site being understood, but not officially published, the Von Kármán diameter crater (186 km ).

The Pole-Aitken Deck Basin is an ancient 1,550m wide (2,500 km), 7.5-mile (12km) deep (12 km) deeper scientific interest that could include open material of upper mantle and clues to & # 39; the history and development of the moon.

James Head, a planetary scientist at the Department of Earth, Environmental and Planetary Sciences in Providence, Rhode Island, said that instruments such as the Lunar Penetrating Radar, were also on the board of Moon Moon Chang's 3 previous mission, providing images of the structure the gray soil layers and any subscription floating flow units, and any interconnected soils, and "help us understand the nature of the three dimensions and the size of subscription units."

The Head of Department stated that the Vector and Ger-infrared spectrum (VNIS) charge is also of great interest and will allow comparisons between the De Pole-Aitken basin floor mineralogy to nearest units and help answer questions such as the Impact of the De Pole Basin -Aitken pervades the white mantle?

No official date was released for the attempt to divert power away, but China's main space program contractor (CASC), China's main space program contractor, stated that soon after launching the landing would take place during the first few days January 2019, following the sun over the main candidate landing within the Von Kármán crater at the end of December.

Originally, Chang 4 was designed as a backup to the Land and Blow 3 mission of the land, which China made the third country in December 2013 to have a soft lunch on the lunch, and & # 39 ; the first of the Soviet Union's 24th Luna in 1976.

The dry massages have 2,650 lbs. (1,200 kilograms) and it carries 310-lbs. (140 kg). During the launch, when the spacecraft had weighing around 8,380 lbs, it was loaded with equipment. (3,800 kg).

Chang's mission 4 is to follow China's first sample return return, Chang 5, which could be launched at the end of 2019 on a March 5 long rocket.
