In a test aimed at boosting its defences in space, India used an indigenously developed ballistic missile interceptor to destroy one of its own satellites at a height of 300 km.
Nasa had said that India's anti-satellite missile test created at least 400 pieces of orbital debris placing the International Space Station (ISS) and its astronauts at risk.
"Even though the interceptor has the capability to intercept at the altitudes of more than 1000km, it has been very specifically created to have an interception below 300 km to ensure the safety of space assets and also that debris there decays very fast", he said.
The Ministry of External Affairs had said the test is significant because India has "tested and successfully demonstrated its capability to interdict and intercept a satellite in outer space based on complete indigenous technology".
India's recent test of anti-satellite (A-SAT) missile has been termed as "a bad, awful thing" by NASA.
After NASA warned of the danger the debris posed, Pentagon, on Thursday, downplayed the threat and said that debris from an Indian A-SAT weapons test would eventually burn up in the atmosphere.
Meanwhile, on March 27, Prime Minister Narendra Modi announced that India has entered the elite space superpower category with the successful testing of an anti-satellite weapon under Mission Shakti.
Mission Shakti has ensured that it secures a place in the space power league.
DRDO chief Satheesh Reddy, earlier today, lauded the operation, noticing that space has gained importance in the military domain.
Clearance to conduct the test was received in 2016 when the programme to develop the interceptor missile began in earnest, Reddy said.
Many satellites, including the International Space Station, operate from much higher orbits. "All necessary permissions were taken", he said. The test created almost 3,000 pieces of debris, AFP had reported. We don't need any more tests in this orbit as of now.
Asked if India has informed United States of America or other nations about the test, Saran admitted that India was "in touch" with other space powers. NASA Administrator Jim Bridenstein talked about 60 bits have been tracked so far and from that 24 are going over the apogee of the ISS.
