On July 24, the Wentian experimental module was successfully launched at the Wenchang space launch site in my country. The Wentian experimental module is the second section of the Chinese space station and the first scientific experimental module.
On July 29, instructions were injected through the ground program, and the plant cultivation experiment was launched in orbit.
At present, the Arabidopsis seedlings have grown four leaves, the tall rice seedlings have grown to about 30 cm high, and the dwarf rice is also 5 to 6 cm high, and they are in good growth condition.
According to Zhao Liping, the chief designer of the space application system Wentian experimental cabin mission,The preliminary plan is that around the end of September, the astronauts will carry out the first collection of plant samples and plants. That is, before the Shenzhou 14 astronaut crew returns, the plant samples will be harvested and brought back to Earth.
Plant collection was completed by the astronauts in the glove box, and then placed in a temperature zone of -80°C, and the seeds were placed in a temperature zone of 4°C.
Before the astronauts return, they will be placed in a descending cold pack under passive life protection conditions, and scientists will do more in-depth research.
The model in the figure above isThe one-to-one restoration of the life ecology experimental cabinet in the Wentian experimental cabin is also the main part of the plant culture experiment. Arabidopsis is grown on the left and rice is grown on the right., in their respective suitable growth environment, the whole process, the whole cycle of growth and cultivation.
At the same time, there are three other experimental modules, and the respective experiments will be started gradually in the future.
