The Sputniks 1 satellite, launched in 1957, was a milestone mission and marked the start of human’s journey to space. Driven by our stronger dreams to explore the deep space and with the aid of the fast-developing technologies, human’s activities have extended to the space far away from Earth, with destinations including the Moon, the planets and small bodies in our solar system. Numerous missions have been launched. The one that travels the furthest from Earth is the Voyager 1 spacecraft (NASA), which obtained images of Saturn and Jupiter during their flybys. Currently, it has arrived at the outer solar system, i.e. the edge of the solar influence and interstellar medium.
