During the on-orbit mission, the accompanying satellite will carry out the accompanying flight of space assembly and multi-platform space cooperation test, provide support for the technical test of the main spacecraft, carry out a number of new technical tests and expand the application of space technology.
On the ground, due to gravity, it is impossible to build a large liquid bridge, but in the microgravity environment of space, it is possible to build a large liquid bridge. Using large-scale liquid bridge, scientific experiments of microgravity thermocapillary flow can be carried out. In the words of Kang Qi, a researcher at the Institute of Mechanics, Chinese Academy of Sciences, "In order to produce high-quality semiconductor materials, it is necessary to scientifically control the influence of buoyancy convection and capillary convection during the growth of monocrystalline silicon, and the unique microgravity environment in space will enable scientists to deeply analyze the real process of capillary convection."
"Celestial pole" is not an ordinary gamma-ray telescope, but an artifact to detect the polarization of gamma rays emitted by gamma bursts. So what are gamma rays, gamma bursts and polarization? What's wrong with the "celestial pole" telescope, which is as diligent and lovely as a bee? For details, please move and watch. ?
As the saying goes, "before the soldiers and horses move, food and grass come first", which is not only one of the important research topics of space biology, but also an important guarantee for human beings to explore space for a long time. Although many plant growth experiments have been carried out in space, in order to successfully produce food and vegetables in space and provide food sources for astronauts' long-term space life, it is necessary to solve many problems such as the influence of extreme environmental factors including microgravity on plant growth and development.
The main task of Tiangong-2 Higher Plant Incubator is to cultivate plants. However, this training process is different from the past. This will be the first six-month plant life cycle culture in China, and it will be broadcast live.
