China’s Chang’e 6 to Deploy French DORN Instrument on Moon to Study Lunar Exosphere

BEIJING (CNES PR) — Wednesday 6 November, on the occasion of President Emmanuel Macron’s state visit to the People’s Republic of China, CNES President Jean-Yves Le Gall and Zhang Kejian, Administrator of the China National Space Administration (CNSA), signed in the presence of Presidents Macron and Xi Jinping a joint statement covering two fields of investigation.

First, in 2023 China’s Chang’e 6 lunar mission will fly the French DORN instrument proposed by the IRAP astrophysics and planetology research institute. DORN’s science goals are to study the transport of volatiles through the lunar regolith and in the lunar exosphere and lunar dust.

China Lunar Plans Focused on South Pole

China’s aggressive long-range program explore the moon includes a heavy focus on the south pole where probes have detected water.

China’s Chang’e-4 mission is currently exploring the moon with a rover and lander on the far side. The vehicles are communicating with Earth via an orbiting spacecraft. The Chang’e-4 mission also includes two lunar CubeSats, one of which is still operational.

China plans to launch the Chang’e-5 mission by the end of 2018 to bring back soil samples from the lunar surface. The plan is to bring back at least 2 kg (4.4 lb) of soil from the Mons Rümker region in the northwest section of the moon.

Xinhua reports there are three other moon missions planned in the years ahead:

  • Chang’e-7, set for launch in 2023, will carry out comprehensive surveys of the south pole;
  • Chang’e-6, scheduled to be launched in 2024, will bring back samples from the lunar south pole; and,
  • Chang’e-8, scheduled for launch in 2027, will test technologies to lay the ground work for a research base on the lunar surface.

China expects to conduct crewed missions to a lunar base sometime during the 2030’s.
