India has refused to comment on Nasa claims that astronauts have been endangered by its decision to blow up a satellite in space.
The space agency said that people on board the International Space Station were now living with the risk of being hit by the debris that has been distributed above the Earth and could collide with the floating lab.
India's defence ministry spokesman Colonel Aman Anand said there was no official response to Nasa administrator Jim Bridenstine's statement at a town hall event in Washington on Monday.
Mr Bridenstine said, in shooting down one of its own satellites with a rocket last week, India had left debris high enough in orbit to pose a risk to the International Space Station.
India's external affairs ministry in a statement after the March 27 test said that whatever debris generated would decay and fall back to Earth within weeks as the test was in the lower atmosphere.
The International Space Station serves as a research laboratory and has hosted astronauts from various countries since it was launched into orbit in 1998.
Mr Bridenstine said Nasa had identified 400 pieces of the debris and tracked 60 of them.
"We know that 24 of these are going above the apogee of International Space Station. That's a terrible, terrible thing to create," he said.
India's prime minister Narendra Modi announced the test last week and said the destruction of the satellite demonstrated India's capacity as a "space power" alongside the United States, Russia and China.
Pallava Bagla, a science writer at the New Delhi Television Channel, said Indian officials have clearly indicated that the debris will decay in three weeks.
"The amount of debris which the United States itself has created in space is gigantic as compared to a few pieces of debris from the Indian test.
"In orbit, we have 2,000 functional satellites.
"Eight hundred of them belong to the United States. India has only 48 functional satellites in the orbit," he said.
In Washington, the vice commander of US Air Force Space Command, Lieutenant General David Thompson, told a Senate Armed Services Committee hearing last week that the Air Force detected about 270 objects in the debris field created when India destroyed the satellite and the number was likely to increase.
He said the Air Force will inform satellite operators if any of those objects become a threat to satellites in orbit.
