Technosignature Research Portal

Earth's first artificial satellite, Sputnik I, orbited the Earth in 1957, and over the past half century nearly 10,000 additional satellites have been launched, roughly half of which remain in orbit today. A technologically advanced civilization will presumably be similarly inclined to deploy technology into orbit for scientific or commercial gain, and over time, the number, size and utility of artificial satellites may increase on par.

Detectability

• Natural satellites are potentially detectable when transiting a planet by the dimming of the parent planet's light curve.
• Similarly, a sufficiently large number of artificial satellites could also be detectable by their influence on the light of their parent planet, although differentiating between natural and artificial satellites would represent an extreme challenge of resolution for any telescope.
