More than half of working satellites are now owned by a single company, Elon Musk's Space X company. They plan to have a mega-constellation of roughly 42,000 satellites.
"We have launched more satellites in the past six years than we had in the previous 60," astrophysicist and co-director of the Outer Space Institute Aaron Boley said in his 2024 Dan MacLennan Memorial Lecture in Astronomy. It was held at Saint Mary's University in Halifax in late November.
Boley says Space X satellites are built for rapid development and obsolescence. There are around 2,200 abandoned rocket bodies in orbit — and since what comes up must come down, more and more space debris is crashing down on Earth.
