The area of space closest to Earth, known as low-Earth orbit, is littered with junk - defunct satellites, discarded rocket modules, and debris from collisions and explosions. Even the smallest of these could penetrate the International Space Station's crew module shields. The International Space Station had to change its orbit three times in 2020 - and levels of junk in low orbit have increased by 50 percent in the last five years. Eventually, this could trigger the Kessler Syndrome, a catastrophic chain reaction of collisions and destruction rendering low-Earth orbit unusable for generations. #RAZOR @Razor #CGTNEUROPE @cgtneurope You can also find Razor on: Website: https://www.cgtn.com/europe/razor Instagram: https://www.instagram.com/cgtneurope/ Facebook: https://www.facebook.com/cgtneuropeof...
