US Military Detected India A-Sat Missile Test

Criticising India for the tests, NASA had described it as a "terrible, terrible" thing that had endangered the International Space Station (ISS).

Addressing the media for the first time after the anti-satellite launch on March 27 along with Defence Research and Development Organization (DRDO) G. Satheesh Reddy, Deputy National Security Advisor Pankaj Saran said that India is already actively engaged in all relevant worldwide negotiations on outer space, including a group of experts on prevention of arms race in outer space.

He also responded to a question on Congress leader P Chidambaram's criticism of the government on the test, who had said that "only a foolish government" would reveal a defence secret. The US had also done a test at a similar height. But the ASAT test was "intentionally done at a lower orbit of 280 km to ensure that the debris decay very fast", Reddy said. Bridenstine continued to say that this type of risk to humans in space, and low Earth orbit operations, was just not acceptable. But the scientists at the DRDO clarified that the threat of debris is not much. "And this has been proven true, even NASA spoke about a 10-day risk period that is over today", he said. "Our simulations show all debris will decay in 45 days", he added.

Reddy's comments come against the backdrop of criticism from the U.S. space agency - the National Aeronautics and Space Administration (NASA) - whose administrator Jim Bridenstine said that India's ASAT test had created about 400 pieces of debris of which 24 were in an orbit near the International Space Station. On Thursday, Bridenstine had reportedly promised to continue its cooperation with the Indian Space Research Organisation. He also asserted that the best way of defence is to have deterrence. The satellite is tracked by many stations across the world and all the necessary permissions were taken to carry out the test, he added.

On March 27, Prime Minister Narendra Modi had announced that India had shot down a live satellite in space and had become the fourth country to do so. On March 27, India achieved a historic accomplishment by firing down its low orbit satellite. "If a space command needs to be formulated, it is the decision of the government".

About 150 scientists worked round-the-clock in the past six months and about 2,000 components were sourced from 50 private industries. The mission was conceived in 2014 and development started in 2016.
