With successful testing of anti-satellite missile in India, the world expressed concern over space junk generated from the satellite that was shot down.
Space junk is an ever-growing problem with more than 7,500 tonnes of redundant hardware now thought to be circling the Earth.
The rising population of space debris increases the potential danger to all space vehicles, especially The International Space Station (ISS).
Kessler Syndrome, proposed by the NASA scientist Donald J. Kessler in 1978 warns of the dangers of collusion because of the space junk.
