Record number of objects launched into space last year.

U.N. data reports about 4,510 objects were launched in 2025, and there are roughly 12,000 active satellites orbiting Earth today.

Humans launched a record number of objects into space in 2025, including satellites, probes and crewed spacecraft. U.N. data reports about 4,510 objects were launched that year. Since the start of the Space Age roughly 25,000 objects have been sent into space. Scientists and observers are discussing what this growing population of satellites means for astronomy and the atmosphere. Key facts: - U.N. data records about 4,510 objects launched in 2025, and roughly 25,000 objects have been sent into space since the Space Age began. - There are now about 12,000 active satellites in orbit, up from roughly 1,200 a decade ago. - The U.S. accounts for the bulk of recent launches, and a single commercial operator maintains more than 9,000 Starlink satellites that now make up a large share of active satellites. - Researchers report that satellite swarms are already affecting ground-based telescope images and that emissions from launches and re-entering payloads are a growing atmospheric concern, as noted by an atmospheric scientist at University College London. Summary: The recent surge in launches has substantially increased the number of operational satellites and has prompted concerns about impacts on both ground- and space-based observations and on the atmosphere. Undetermined at this time.
