In order to carry out the plan of the lunar surface antenna, it is necessary to use the space shuttle to transport the parabolic antenna with a large diameter to the moon. However, how can such a large antenna be installed in a very narrow space shuttle? NASA uses shape memory alloy technology. Under specific temperature conditions, the physical properties of this alloy will change significantly. It is an alloy with unique shape memory function. After the alloy is pre deformed, when the pre deformed shape memory alloy is heated to make its temperature exceed the alloy transformation temperature, Shape memory alloy materials will return to the shape before deformation. NASA scientists use shape memory alloy to make parabolic antenna at room temperature, and then knead it into a small ball with a diameter of less than 5cm, put it into the Apollo 11 capsule and launch it to the moon. The moon surface is heated by sunlight to restore it to the original parabolic shape. In this way, the space shuttle cabin with limited space can be used to transport the huge antenna.
