What are Solar Sails?

Solar sails (English name: Solar sails) are a kind of spacecraft that make use of the light pressure of sunlight for space navigation. Because this kind of thrust is very small, the spacecraft cannot take off from the ground, but in space without air resistance, this small thrust can still provide about 10e-5 to 10e-3g for a solar sail with sufficient sail area. Acceleration.

Solar sails can hover over the polar regions of the earth. Spacecraft equipped with solar sails can also be positioned in orbits close to the sun and remain stationary relative to the sun or the earth. This form of satellite is named Forward satellite.

• If the altitude of the orbit is less than 800km, the solar sail is basically useless, because the atmosphere at this time

  For a long time, people have long been eager to get rid of the single dependence on rockets, find new ways of power, and realize the human dream of traveling to space. One of them is to make solar sails to use solar energy for space navigation.

  Scientists believe that the "solar sail" spacecraft may be the only hope for human interstellar travel, because using sunlight as the power can reduce the large amount of fuel carried by the spacecraft, increase its range of maneuverability, and make it stay in space longer, As long as there is sunlight, it will continue to gain power to accelerate the flight. The solar sail represents the technology of human space flight in the future. If this experiment is successful, it will take an important step in the direction of developing a new type of cosmic engine. It is believed that humans can fully use solar sails in deep space exploration in the future, Space travel brings a new revolution. Therefore, the fate of "Cosmic One" is not only related to the construction of energy systems in future interstellar voyages, but also to people's attitude towards the development of solar sails.
