"That is a bad, awful thing, to create an event that sends debris in an apogee that goes above the International Space Station", Bridenstine said at the town hall meeting, which was livestreamed on NASA TV. A third of those were created in previous anti-satellite weapons tests by Russia, China and the U.S. itself.
According to The Guardian, NASA administrator Jim Bridenstine told employees that the satellite had exploded into pieces some dangerously large but unfortunately too small to track. "Of these 60, we know that 24 of them are going above the apogee of the International Space Station", Bridenstine added. The United States military is now tracking 23,000 objects in space, of which 10,000 are debris. "What we are tracking right now, objects big enough to track - we're talking about 10 centimetres [six inches] or bigger - about 60 pieces have been tracked", the agency quoted him as saying.

"The issue of space debris, that is an important concern for the United States, and I would say that we took note of the Indian Government's statements that the test was created to address space debris issues", US State Department deputy spokesperson Robert Palladino said. "Whatever debris that is generated will decay and fall back onto the earth within weeks".
Despite the satellite being destroyed at a low altitude of approximately 289 km some debris has still gone above the ISS which is at an orbit height of about 400 km. "Space debris is composed of satellites, parts of launch vehicles, etc".
According to Bridenstine, the USA is now tracking about 23,000 pieces of orbital debris that are 10 centimeters or bigger.
With 830 satellites, United States leads the world in the number of satellites, followed by China with 280 satellites.
The US, he said, is doing it for free with the its taxpayers money from an orbital debris field that was created by another country. The senior advisor to ISRO's chairperson said that the organisation would not do anything "to shame India" and added that the debris will burn out in six months.
The task of tracking potentially risky debris is mostly left to NASA, which has struggled to catch up with the growing problem.
"When one country does it, other countries feel like they have to do it as well", he said. "It's unacceptable", Bridenstine said in response to a question about India's Mission Shakti at an event.
"All of those are placed at risk when these kinds of events happen", Bridenstine said as he feared India's ASAT test could risk proliferation of such activities by other countries. It was the first time that India has ever successfully tested such technology.
