Deep space is defined by the United States government as all of outer space which lies further from Earth than a typical low-Earth-orbit, thus assigning the Moon to deep-space. [118] Other definitions vary the starting point of deep-space from, "That which lies beyond the orbit of the moon," to "That which lies beyond the farthest reaches of ...
In such statements, "reaching the edge of space" merely refers to going higher than average aeronautical vehicles commonly would. [11] [12] There is still no international legal definition of the demarcation between a country's air space and outer space. [13] In 1963, Andrew G.

Space exploration is the use of astronomy and space technology to explore outer space. [1] While the exploration of space is currently carried out mainly by astronomers with telescopes , its physical exploration is conducted both by uncrewed robotic space probes and human spaceflight .
