China is getting out for her & # 39; First launch of surface to the far side of the moon.
The Chang's 4 strategic mission is to launch on the Long 3B rocket Friday (December 7) at 1:30 p.m. EST (1830 GMT; 2:30 a.m. on the 8th century of the local Chinese).
If everything is done according to their plan, both Changer will lander-rover to & # 39; link down within the Pole-Aitken (SPA) Ocean after a 27-day flight, then scrolling the surface and suburbs of this section. [China’s Moon Missions Explained (Infographic)]
Both the outside and the rover were designed as a supporter for China's successful China's 3 successful mission, and the Yutu named rover released its moon in December 2013.
As a prelude for Chang 4, China launched the Queqiao relay satellite in May. Queqiao is now based at L2 Lagrange point – a place where the spacecraft can handle communications between land rulers and the rover-rover session on the other side.
Resource of scientific knowledge
It is expected that Changes 4 will go down at Von Kármán Crater, within the SPA bay.
In an analysis published last year, Yingzhuo Jia, from the Chinese Academy of Sciences Academy, and the mission cooperative objectives of the mission. (Jia is also with the State State Attorney of Rum Weather, the National Sciences Science Center of the Chinese Academy of Sciences).
The purpose, Jia and team members, aims to complete it:
Low-level radio-relay survey on the surface of the moon;
Investigate the dysfunction structure at the pond on the other side of the river;
Topographic and mineralogical tests on the outside pond within a patrol area.
The radio-rhetoric study is particularly interesting. The pool on the other side is always looking away from Earth, and so it's free to do it. including an ionosphere on planet plan, humanized radio frequencies and sound radiation sound. Sun radio distribution is also stopped during the moon.
"So the pool on the other side has been convinced as the best place to watch low radio radios," write the researchers in the # 39; recent paper.
The paper also reported on the eight scientific payrolls that were damaged by resolution.
The Landing Camera 4 carries the Landing Camera (LCAM), the Terrain Camera (TCAM), the Low Low Spectrometer (LFS), and the Lunar Lander Neutrons and Dosimetry (LND), which gave her Germany. The rover also has four instruments: the camera (PCAM), the Lunar Beautiful Radar (LPR), the Spectrometer Expressive Image and Near Infrared (VNIS), and the Advanced Neutral (ASAN) Inspector, which was taken delivered by Sweden.
The LFS was newly renovated for Chang 4 on land; The other indigenous Chinese payroll payments acquire instruments from Chang 3, written by the researchers.
The Queqiao relay satellite also carries an instrument called the Netherlands-Low Frequency Explorer (NCLE). The NCLE and LFS make an external low-radio radiological evaluation. [Moon Master: An Easy Quiz for Lunatics]
It is likely that the LPR instrument will be able to find a sub-sound structure on the robot's defense, and to detect the proficiency and structure of the moon's regime. The machine is a nanosecond impulse radar with bistatic antennas.
He works like this: a broadcaster produces a broadband nanosecond machine, and then sent through the antenna to a; move down to the surface of a moon. The replica signal can be found from the underground target with the antenna received, extended in the receiver and then restored as a data record.
A biological test too
According to an earlier story this year with a Xinhua-based Xinhua-based journalist, Chang & 4 also has a potato seed and arabidopsis, a pale twisted palate and mustard. It can also offer silkworm eggs.
This "grunnd" biosphere "test was designed by 28 Chinese universities, led by the University of Chongqing China to the southwest. The cannon tin, made of special aluminum aluminum materials, is a # 39 ; focusing around 6.6 pounds (3 kilograms).
The SPA field is the largest and oldest part of its location. moon. Although the land is very low, this section is not full with sea basalts, such as other white mills, Jia and colleagues who note, and # recommends that special thermal history may exist and have special features.
So checking the materials in the department can help to print out its & # 39; crown and even white moon, written by the researchers.
China's Chinese shirt changer, Chang 5, is designed to select samples from the moon back to Earth. It builds on the progress of Chinese moon explorers: Chang Changes 1 and Chang 2 in 2007 and 2010, respectively, Changes 3 in December 2013, and Chang 5 T1, which launched a test captain on a tour of the moon in October 2014. The capsule was safely measured back to the Earth eight days after its expansion.
