Experts warn of the increasing threat of space junk falling to Earth, as more satellites are launched.
Satellites are increasingly being used for communication, television, navigation and weather forecasting. Experts and researchers have been investigating different options to reduce the space junk.
According to the World Economic Forum, there are nearly 6,000 satellites circling Earth. About 60% are defunct (space junk).
Research firm Euroconsult estimates 990 satellites will be launched every year this decade, which means that by 2028, there could be 15,000 satellites in orbit.
Elon Musk’s SpaceX has already launched over 900 Starlink satellites and has plans to deploy thousands more.
Space junk travels at an incredibly fast speed of over 22,300 miles per hour, causing considerable damage to any objects it hits. In 2006, a tiny piece of space junk collided with the International Space Station, taking a chip out of the heavily reinforced window.
