For example, on 5 September 1977, America’s NASA space agency launched Voyager 1 to study deep space, and it still transmits data today. And the International Space Station(1998) has provided a continuous human presence in space, with astronauts from many different countries on board.

On 23 July 2020, China sent Tianwen 1 to explore the surface of Mars. It arrived in February 2021 and then sent back lots of valuable information. And from 2021 to 2022, China completed a number of rocket missions to establish its own space station. In 2022, the launch of the Mengtian module signaled the basic completion of the Tiangong Space Station. This modern space station will allow astronauts to conduct many important experiments, greatly furthering our understanding of the universe.
