The Union of Concerned Scientists estimates that, as of May 4 2024, Earth had 9,900 active satellites. Most of these satellites are not government-owned weather satellites or large communications satellites. The vast majority — seven out of every ten — are SmallSats.
Various national space agencies operate some of these SmallSats. Others serve military purposes. Quite a few are designed and built by universities, non-profit organizations, and even by school children. However, the vast majority are commercially-owned SmallSats.
The rising population of small satellites is due to the many unique benefits they offer for science, business, and society.
