CHINA AND THE HIDDEN SIDE OF THE MOON

Beijing / The Chinese probe Chang’e 4 entered into lunar orbit on Wednesday, completing a key step to make what would be the first ever landing on the hidden side of the moon, the National Space Administration of China announced.

After flying about 110 hours from Earth, the probe began to slow down and entered the elliptical lunar polar orbit with a perilune of 100 kilometres, in line with the instructions sent from a control centre in Beijing.

On Wednesday, the entrance in orbit was completed at 4:45 local time (08:45 hours GMT), reported official newspaper People’s Daily.

The probe, which includes a module and an explorer vehicle, was launched on Saturday by a Long March-3B rocket from the Xichang Satellite Launch Centre in Sichuan Province in the south-west.

The state news agency Xinhua said the rocket sent the probe into “lunar orbit” as planned, and the control centre only had to make “small adjustments” before the slowdown process.

The control centre will then adjust the orbit of the probe around the Moon and test the communication between the probe and the Queqiao data relay satellite, the information adds.

Afterwards, the centre will choose the “right time” to complete the landing, which Beijing foresees for the beginning of January.

According to the agency, the mission will perform tasks of low frequency radio astronomical observation, terrain and relief analysis, detection of mineral composition and shallow lunar surface structure and measurement of neutron and neutral atom radiation to study the environment on the hidden side of the Moon.

Last August, China revealed images of the exploration vehicle with which it hopes to examine it, something that no country has yet achieved.

Pioneering space programs such as the Soviet or the American have already achieved more than half a century ago photographing the hidden face but they have never landed there, despite the fact that in 1962 a US unmanned mission tried unsuccessfully.

Last May China took the first step for this new mission with the launch of a satellite to facilitate communications between the lunar hidden face and the control centres on Earth.

The Chang’e program (named in honour to a goddess who, according to Chinese legends, lives on the Moon) began with the launch of a first orbital probe in 2007, and since then four devices have been brought to Earth’s satellite.

The final objective of the program is a manned mission to the Moon in the long term, although the date for this has not been set and some experts place it around the year 2036. (December 13, 2018, EFE/Practica Español)
