Temperature and light conditions at the Moon's south pole are suitable for long-term human presence, and even for the exploration into deeper space, said Wu Weiren, chief designer of China's lunar exploration project, in an interview with China Central Television in Tunxi of Anhui in east China on Thursday.
During a two-day space conference held in Tunxi, the China National Space Administration (CNSA) and its counterpart in Senegal signed an agreement on International Lunar Research Station (ILRS) cooperation during the conference.
The ILRS project will be implemented in two phases. The first phase will see a basic facility built by 2035 in the lunar south pole region, while the second phase aims to establish a network connecting the Moon's south pole, equator and far side by 2050.
Wu, who is also director and chief scientist of Deep Space Exploration Lab (DSEL), said that the temperature and light are adequate for human exploration at the Moon's south pole.
"The Moon revolves around the Earth, and the Earth revolves around the Sun, which inevitably has a rotation angle. From that angle, the Sun might shine on the south pole of the Moon for a long time. This is similar to the polar day and night phenomena we see on the Earth, which occur in both the Antarctic and Arctic regions on the Earth. The same phenomena also happen to both poles of the Moon. According to scientists' deduction, or based on our international counterparts' previous long-time scientific exploration, we should strive to have people go up to the Moon in a short term. Then we could see whether there is water in the permanent shadow pits there. If we can find water molecules and direct evidence of the existence of water ice on the Moon, it will be amazing. That will pave the way for humans to stay on the Moon for a long time and even lay a foundation for humankind to reach farther deep space from the Moon, such as Mars or other planets. That would be surely great," Wu said.
The ILRS initiative, officially launched by the CNSA in 2017, has garnered international interest, with more than 40 institutions from around the world already signing agreements for cooperation with China.
