WASHINGTON, April 2 - India shooting down of one of its own satellites was a �terrible thing� as it created about 400 pieces of orbital debris, the chief of NASA has said, warning that the risk of debris colliding with the International Space Station has risen by 44 per cent since the Indian anti-satellite weapon test.
Prime Minister Narendra Modi announced on March 27 that India has achieved a �historic feat� by shooting down its own low-orbit satellite with a ground-to-space missile, making the country a �space power.� Only three other countries � the US, Russia and China � have anti-satellite missile (ASAT) capabilities.
The National Aeronautics and Space Administration (NASA) Administrator Jim Bridenstine said about 60 pieces of debris have been tracked so far and out of which 24 are going above the apogee of the International Space Station (ISS), the point of the space station�s orbit farthest from the Earth.
�That is a terrible, terrible thing to create an event that sends debris and an apogee that goes above the international space station. That kind of activity is not compatible with the future of human spaceflight that we need to see have happen,� he said at a NASA townhall with employees on Monday. �The Anti-satellite weapons test by India last week has resulted in about 400 pieces of orbital debris,� he said.
Bridenstine said not all of the pieces were big enough to track and the NASA is right now tracking objects which are 10 centimetres or bigger. �Some 60 pieces of orbital debris have been tracked so far, 24 out of which poses risk to the ISS,� he said.
India has said the test was done in the lower atmosphere to ensure that there is no space debris. �Whatever debris that is generated will decay and fall back onto the earth within weeks,� the Ministry of External Affairs said soon after the test. By conducting the ASAT test, India was not in violation of any international law or treaty to which it is a party to or any national obligation, it said.
Interestingly, Bridenstine is the first top official from the Trump administration to come out in public against the India�s ASAT test. A day after India successfully carried out its ASAT test, acting US defence secretary Patrick Shanahan warned that the event could create a �mess� in space but said Washington was still studying the impact. � PTI
