AKIPRESS.COM - Nasa has called India's destruction of a satellite a "terrible thing" that could threaten the International Space Station (ISS), BBC reported.

The space agency's chief, Jim Bridenstine, said that the risk of debris colliding with the ISS had risen by 44% over 10 days due to the test.

However he said: "The international space station is still safe. If we need to manoeuvre it we will."

India is the fourth country to have carried out such a test.

Prime Minister Narendra Modi announced the test - Mission Shakti - with great fanfare on 27 March, saying it had established India as a "space power".

In an address to employees, Mr Bridenstine sharply criticised the testing of such anti-satellite (ASAT) weapons.

He said that Nasa had identified 400 pieces of orbital debris and was tracking 60 pieces larger than 10cm in diameter. Twenty-four of those pieces pose a potential risk to the ISS, he said.
