The Era of Human Aerospace 'Star'

On October 4, 1957, the Soviet Union launched humanity's first artificial satellite, Sputnik 1, ushering in the space age. On January 31, 1958, the LC-26 launch pad at Cape Canaveral successfully launched the first artificial Earth satellite of the United States, Explorer 1, into space. On November 26, 1965, France's first artificial satellite "Asterix" was launched into space by the Diamond carrier rocket. On February 11, 1970, Japan's first artificial satellite, "Osumi," was launched into orbit by an L-4S-5 rocket from the Uchiura Space Center. On April 24, 1970, China's first artificial satellite, Dongfanghong-1, was successfully launched by the Long March 1 carrier rocket from the Jiuquan Satellite Launch Center. China became the fifth country in the world to independently develop and successfully launch a satellite, following the Soviet Union, the United States, France, and Japan. On October 28, 1971, the United Kingdom.

The unit is designed for unsupervised public use: controls are recessed or shielded, moving parts are enclosed, and the interface is operable by a child of about six with no instruction. Where a screen is used, the language can be switched without changing the hardware, and the content can be replaced on site.

Sputnik-1, also known as "Artificial Earth Satellite-1", was the first artificial Earth satellite developed and launched by the Soviet Union. It is a metal spherical object with a diameter of 0.58m and a weight of 83.6kg, containing two radar transmitters, four antennas, and multiple pressure and temperature regulators. Its purpose is to send signals to Earth to indicate changes in air pressure and temperature in space. Sputnik 1 is not only an artificial satellite, but also a scientific experimental platform. Its launch has propelled the development of space science and made significant contributions to our understanding of the roles of Earth, the universe, and humanity in the universe.
