Space is running out of space ;-)
Humans have put 8,378 objects put into space since the first Sputnik in 1957 and at the beginning of 2019 4,987 satellites were still up there, and 1957 are operational. From 1964to 2012 roughly 131 satellites were launched every year. In 2017 453 satellites were launched in space. In 2018, the number fell to 382. But 5200 are planned over the next four years and another 9,300 thereafter. That’s 15,000 satellites. First, wow…. how far have we come where the cost of launching a bird is so cheap now. Secondly, the unintended consequences of these many birds are going to be pretty substabtial. No one should be surprised if some complications develop overhead and cause problems down on the planet.
