Space probes are satellites designed for robotic space exploration outside of Earth, and space stations are in essence crewed satellites. The first artificial satellite launched into the Earth's orbit was the Soviet Union's Sputnik 1, on October 4, 1957. As of December 31, 2022, there are 6,718 operational satellites in the Earth's orbit, of ...

A pair of European satellites rocketed into orbit Thursday on the first mission to create artificial solar eclipses through fancy formation flying in space. “We are a very happy science team ...
Currently, an artificial satellite called the Deep Space Climate Observatory (DSCOVR) is located at L 1 to study solar wind coming toward Earth from the Sun and to monitor Earth's climate, by taking images and sending them back. [3] The James Webb Space Telescope, a powerful infrared space observatory, is located at L 2. [4]
