India, on March 27, tested its A-SAT missile and shot down a low-orbit satellite which made India one of the four space powers of the world. But now, the missile test has been termed as a 'terrible thing' as the destruction of the satellite shot down has left 400 pieces of orbital debris which has created more dangers for astronauts un the International Space Station.

"What we are tracking right now, objects big enough to track - we're talking about 10 centimeters or bigger - about 60 pieces have been tracked," said Jim Bridenstine while addressing the employees of NASA stating that some of the pieces of debris could not be tracked.

Although the satellite which was shot down by India was at a relatively low altitude of 300 kilometres which is very much a lower height than the International Space Station and most of the satellites.

"But 24 of the pieces are going above the apogee of the International Space Station," said Bridenstine.

"That is a terrible, terrible thing to create an event that sends debris at an apogee that goes above the International Space Station. That kind of activity is not compatible with the future of human spaceflight," added Bridenstine.

The US military is involved in the tracking of such debris objects and is currently tracking 23,000 of them.

Historically, China's similar test in 2007 created 3000 such pieces and the Indian ASAT test has reportedly increased the risk of collision with ISS by 44 per cent.
