China launches historic mission to land on the far side of the moon – Spaceflight Now

A robotics land and rover raised the Friday (US time) in Xichang space center in China, and began a journey that will end in an attempt to touch the far side of the moon in the first month of January.

Chang .e 4 mission – the fourth in the series of major moon pullers in China, came out from Xichang, a space ship between the hills in southwest China's Sichuan province to 1823 GMT (1:23 p.m. EST).

Chang climbed into the night sky at 4, Xichang. Life recovery took place on Saturday at 2:23 in Beijing – to the east, adhered to the top of the Long March 3B rocket.

The Chinese state television did not broadcast its launch live, as was the launch of the previous month's mission in China in 2013, but the audience near Xichang released the live video of blastofun at midnight without a comment. The video showed that after a few minutes of apparently proper removal of Xichang, the Long Mart 3B was shifting into the night sky.

The three-stage Long March 3D rocket was programmed to inject Chang enje 4 spacecraft into an orbit less than half an hour before launching.

Chang .e 4 is expected to enter the orbit of the moon later this month, then use the rockets on the moon route to land on the moon's surface and aim to land in the Von Karman crater in the South Pole-Aitken basin of the Moon in early January.

No task examined the surface of the far side of the moon, and if successful, Chang has reached a long-standing goal on the To-do list of 4, NASA and international space, a first in Space Travel. Scientists.

Chang .e 4, reaching the moon in December 2013 with a decrease in the Mare Imbrium volcanic basin on the nearby side of the month, China's Changike uses built-in replacement hardware for 3 months lander and roaming.

The rider stopped driving a few weeks after landing, but some of the vehicles' instruments continue to work. According to Chinese scientists, named as Yutu and designed to reach a speed of 6 miles (10 kilometers), the Chang’e 3 rover traveled about 374 feet (114 meters) before losing its mobility.

In a presentation made for Chinese scientists, Jun Huang from the Institute for Planetary Science of the University of China's Geosciences, n Mare Imbrium, including Chang Chang . We have a successful mission, başarılı he said. March in Texas' Science Moon and Planet Science Conference. ”The task took about five years and greatly increased our knowledge of the moon, but we didn't have a mission to take sensitive matters on the far side of the Moon (until Chang bile 4 ve).“

There are some important differences between Chang 3 and Chang 4. For example, the descent to the far side of the moon will not carry a robotic arm or an Active Particle X-ray Spectrometer. Moon rocks and chemical elements in soil.

In addition to a camera set on both the fixed terrain and the rover, this task is intended to offer a new set of sensors to the moon surface, some of which are provided by European scientists.

The landing module, which will launch a rocket-driven landing such as the Chang'e 3, will carry a low frequency radio spectrometer developed by Chinese scientists for astrophysical research. A German-developed neutron and dosimetry instrument will measure the radiation levels at the landing site of Chang & # 39; s, collect data that may be useful in planning human exploration of the distance, investigate solar activity, and measure groundwater content in Von Karman.

The Chang .e 4 rover will provide a radar that penetrates the ground to inspect the visible and near infrared spectrometer to collect data on the geological layers and soil composition buried under the landing area. The Chinese authorities approved the addition of a Swedish instrument to study the interaction between the solar wind and the surface of the moon that was not protected by a bombardment of charged particles caused by the sun.

Chang .e 4 will also deliver a carrier designed by the student that includes potato seeds and silkworm eggs into the moon. University students and scientists will take part in a room and once on the moon surface will monitor the growth of organisms fed with natural light and nutrients.
