After concerns over orbital debris in the aftermath of the Mission Shakti anti-satellite (A-SAT) strike, DRDO chief G Satheesh Reddy on Saturday said that all debris should decay within 45 days from the day of the launch.
"Firstly, the Mission has been created to see that debris decays very fast and it has been designed in a manner that minimal debris goes up", he said at a program organised here to give more information about the Anti-Satellite test. "The US has also done such a test", the DRDO chief said. "The satellite is tracked by many stations across the world".
Asked whether the DRDO had the permission of the Election Commission (EC) for the briefing, officials said they had the "necessary clearance".
Only three other countries, US, Russia and China - have anti-satellite missile (ASAT) capabilities. To this, Reddy responded, "The debris won't cause a problem to any existing global space assets".
India has been developing "space deterrence" technologies which would be able to knock out enemy satellites, the country's military research chief has revealed.
Commenting on P Chidambaram's statement on Mission Shakti, Reddy said that a mission of this nature can't be kept secret.
US Homeland Security head to leave role

On Tuesday, the NASA had termed India's shooting down of one its satellites as "terrible thing" and said the hit-to-kill mission created about 400 pieces of orbital debris. The best way to ensure security is to have deterrence.
"If a space command needs to be formulated, it is the decision of the government", he said. However he said that destroying a satellite on objective is not right and some countries are doing this and creating debris and then they we are approached finally for space awareness.
Addressing the mediapersons, Reddy also said, "For a similar application we don't need another test".
On March 27, Prime Minister Narendra Modi, in a televised address to the nation, announced that India has entered the elite club of nations to possess the capability to hit a target in space.
The successful test of India's brand new anti-satellite weapon last month has drawn criticism from NASA and Pakistan, but New Delhi does not plan to stop yet.
Amid political debate on when the project was initiated, Reddy said the first discussion on the A-SAT test started in 2014 and the formal detailed presentation was made in 2016. About 2,000 components were sourced from 50 private industries.
