Some 4,510 satellites, probes, crewed spacecraft, and space station parts launched into space last year, easily surpassing the previous high of 2,903 objects launched in 2023. Most of the objects sent to space last year were small commercial satellites, the vast majority of which came from the U.S.

Roughly 25,000 objects have been launched into orbit since the dawn of the Space Age, including 14,915 active satellites that currently circle the planet. The bulk of those satellites were launched by SpaceX to build its Starlink Internet constellation, which now totals more than 10,000 active satellites. Experts predict there could be more than 100,000 active satellites orbiting the Earth by 2040.

As low-Earth orbit (LEO) becomes increasingly crowded, the chances of a collision between satellites or space debris goes up, requiring satellite operators to perform a cautious “dance” of course corrections to maintain safety. Solar storms pose a particularly dangerous threat, as they can disrupt satellite operations and potentially disable navigation altogether. A recent study found a total loss of satellite-avoidance maneuvers in LEO caused by a solar storm could lead to a catastrophic collision in as little as 5.5 days, down from the estimated 164-day buffer astronomers had in 2018, before the emergence of megaconstellations. While the study didn’t investigate what would happen after such a collision, if one occurred and course corrections couldn’t be implemented, it may lead to a decades-long runaway cascade of collisions known as Kessler syndrome, theoretically cutting off humanity’s access to space for generations.
