Artist’s illustration of space junk orbiting Earth. (Image credit: NASA) How long would it take for satellites to begin to collide with space junk and each other if they were to suddenly lose their ability to avoid each other? A new study finds that, with the immense quantity of satellites that hurtle in Earth’s orbit

“I’m certainly biased, because my whole work revolves around the cases where modules actually fail,” he says. “It’s easy for me to say that [reliability issues] aren’t taken seriously enough, and I am aware that PV in general works quite well. The majority of modules aren’t interesting to me.” But there is a significant rump
