China’s next robotic lunar mission, Chang’e-7, is slated for departure later this year.

Its target is the Moon’s south pole in a search for and detection of water ice.

“Scientists around the world believe there’s water on the Moon, but no one has found any yet. Now China is going to look for it,” said Ye Peijian, an academician with the Chinese Academy of Sciences (CAS).

“And we’re using many methods, from searching the surface to exploring inside craters,” Ye told China Central Television (CCTV).

Specially designed hopper

The Chang’e-7 mission is composed of an orbiter, a lander, a rover, a hopper and a relay satellite. The specially designed hopper will approach and explore a Sun-deprived lunar shadow crater.

Meanwhile, researchers at the Harbin Institute of Technology’s space laboratory in northeast China’s Heilongjiang Province are conducting experiments to support the Chang’e-7 mission of hunting for lunar water ice.

Lunar soil simulant

“We’ve just created a lunar soil simulant for the Moon’s polar region. Next, we will use this set of equipment to convert that soil into water ice. The equipment can create a vacuum environment on the Moon, said Zhang Weiwei, associate professor at the School of Mechatronics Engineering at the Harbin Institute of Technology.

Zhang told CCTV that the equipment can cool the lunar mineral material down to minus 240 degrees Celsius. Then, this water molecule excitation device will produce a steady stream of water molecules.

“When the water molecules come into contact with the cold lunar soil, they will adsorb and deposit to form ice. By using special tools and molds, we can create samples of lunar water ice,” said Zhang.
