Sharing with friends and circles of friends via wechat scanning QR code < / P > < p > on April 12, the members of the world's first purely private customized space manned mission AX-1, which is composed entirely of civilians, have arrived at the international space station. During their stay, they will participate in many experiments, one of which is to try to make the fluid lens of the telescope in space, which may help NASA build a larger and more powerful telescope than ever before A more powerful space telescope < p > < / P > < p > this experiment is called "fluid telescope experiment" (flute), which aims to study the use of fluid materials to make the lens of space telescope. The project can be completed in space after the material is launched. If this technology proves feasible, the space telescope will be much larger than the similar equipment currently used. This is very important for astronomers, because the larger the telescope is, the more powerful it is. Larger telescopes can collect more light, allowing astronomers to look deeper into space and see distant objects in more detail < p > the AX-1 mission arranged by axiom space, a Houston company, sent four passengers to the international space station. Mission expert Eytan Stibbe will conduct an experiment to demonstrate the technology of making telescope lenses from fluid polymers and hardening them with ultraviolet light or heating. It sounds difficult, but the process is relatively simple, just like making acrylic nails in a nail salon. However, the most attractive part of this experiment is that it uses microgravity to assist lens forming < p > Edward Balaban, chief researcher of the fluid telescope experiment at NASA's Ames Research Center, said in a statement: "in the microgravity environment, fluids can be shaped into the shape of telescope lenses. Therefore, if we make them in space, it is obvious that we can build a telescope that is significantly larger than before." < p > in fact, this fluid technology may even be simpler than the current lens production process. "This method allows us to completely skip any mechanical process, such as grinding or polishing. The natural physical properties of the fluid help us do all the work," Moran Bercovici, an associate professor of mechanical engineering at the Israel Institute of technology, said in a statement < p > the research team of this experiment is composed of scientists from NASA Ames Research Center, NASA Goddard Space Flight Center and Israel Institute of technology. They have demonstrated this technology on earth, first in water simulating microgravity on earth, and then in zero gravity parabolic flight, which can provide researchers with microgravity time of 15 to 20 seconds < p > belkovich said: "sure enough, in a few seconds, we can create an independent liquid lens. Until the plane rises again, gravity plays a role again, and the material returns to fluid. Our experiment on the space station will add a step to deal with these fluids so that they can maintain their shape." < p > balaben said: "if our space station experiment is successful, this will be the first time to manufacture optical components in space. It feels a bit like making history." (small) < / P > < p >
