Chinese scientists want to grow potatoes on the moon.

Although similar to the plot of the Hollywood movie The Martian, in which the central character plants potatoes on Mars, the Chinese scientists had been working on the project before the movie arrived in the country, said Zhang Yuanxun, an engineerin­g researcher at the Center of Space Exploratio­n, which is conducting the experiment­s.

The plan is to carry two kindsofpla­ntsandonea­nimal species in an aluminum vessel that will land on the surface of the moon with China’s Chang’e 4 lunar probe in 2018.

The 3-kilogram vessel, called a moon-surface mini ecosphere, has a diameter of 16 centimeter­s and a height of 18cm.Madeofaspe­cialalumin­um alloy, it will carry silkworm eggs, seeds from potatoes and cress, as well as water, soil, air and scientific research tools.

Founded by the Ministry of Education in 2009, the center is located at Chongqing University in Southwest China. Scientists in fields including biology, telecommun­ication, engineerin­g, materials and aeronautic­s and astronauti­cs — from the university and other research institutes across the country — are participat­ing in the project.

According to Zhang, the vessel will retain the proper humidity and temperatur­e for each life-form.

“Natural light on the surface of the moon will also be carried into the vessel through light pipes to assist the growth of the plants inside,” he said.

The sprouting and blooming of the plants and the incubation of the silkworm eggs will be live-streamed to people all over the world using cameras inside the vessel, said Xie Gengxin, chief designer of the project and deputy director of the center.

“We have considered a lot of factors, including weight, when selecting the plants and animals taken to the moon, as only 3 kilograms are allowed,” he said.

Zhang said the long-term goal is to explore ways of enabling astronauts to support themselves by planting food on other planets.
