There Are Animals On the Moon – Live Science

China’s Chang’e-4 lander touched down on the far side of the moon (Jan. 3 Beijing time, Jan. 2 US), and it’s got some living things on board.

A small “tin” in the lander contains seeds of potatoes and rockcress (Arabidopsis thaliana, a flowering plant related to cabbage and mustard, as well as a model organism for plant biology), as well as silkworm eggs. The idea, according to a report in The Telegraph earlier this year, is that the plants will support the silkworms with oxygen, and the silkworms will in turn provide the plants with necessary carbon dioxide and nutrients through their waste. The researchers will watch the plants carefully to see whether the plants successfully perform photosynthesis, and grow and bloom in the lunar environment.

“We want to study the respiration of the seeds and the photosynthesis on the moon,” Xie Gengxin, chief designer of the experiment, told Xinhua, a Chinese state-run news agency. [See Spectacular Lunar Mission Images in 3D (Photos)]

The “biosphere” experiment was the product of a collaboration between 28 Chinese universities, led by southwest China’s Chongqing University, according to Xinhua. The experiment, which is tucked inside a 1.4-pint (0.8 liters) aluminum alloy cylinder, weighs about 7 lbs. (3 kilograms) and includes dirt, nutrients and water. Sunlight will filter into the container through a “tube,” and small cameras will watch the little environment. That data will beam back to Earth by means of the complicated relay system China has set up to communicate with an experiment that has no direct line of sight to Earth.
