late May or early June 2018, and then launch the Chang’e-4 lunar lander and rover to the Aitken Basin of the south pole region of the Moon about half a year later. The Von Karman Crater in the Aitken Basin was chosen as the landing site for Chang’e-4 as the region is believed to have great scientific research potential. As a gravitational equilibrium can be maintained there, it will be able to stay in stable orbit and operate for a long time. “We will make efforts to enable the relay satellite to work as long as possible to serve other probes, including those from other countries,” said Ye Peijian, a leading Chinese aerospace expert and consultant to China’s lunar exploration program. The Lunar Exploration and Space Program Center of the China National Space Administration (CNSA) has invited the public to write down their hopes for lunar and space exploration. More than 100,000 people have taken part, according to the center.
As the far side of the Moon is shielded from electromagnetic interference from the Earth, it’s an ideal place to study the space environment and solar bursts, and the probe can “listen” to the deeper reaches of the cosmos, said Liu Tongjie, deputy director of the Lunar Exploration and Space Program Center of CNSA.
The Chang’e-4 probe will also carry scientific payloads developed by the Netherlands, Sweden, Germany and Saudi Arabia.
“The Chinese and Dutch lowfrequency radio spectrometers might help us detect 21-cm hydrogen line radiation and study how the earliest stars were ignited and how our cosmos emerged from darkness after the Big Bang,” said Chen Xuelei, an astronomer with the National Astronomical Observatories of the Chinese Academy of Sciences.
A German neutron dosimeter will be installed on the lander to measure radiation at the landing site. Xinhua
