NASA administrator Jim Bridenstine said on Monday that just 60 pieces of debris were large enough to track. Of those, 24 went beyond the apogee of the ISS, the point of the space station's orbit farthest from the Earth.

India's Ministry of Foreign Affairs said in a statement that the test was conducted in "the lower atmosphere to ensure that there is no space debris" and "any garbage that is generated will decay and fall back on Earth within weeks."

"We are charged more activities in space than we've ever seen before for the purpose of benefiting the human condition, whether it's pharmaceuticals or printing human organs in 3-D to save lives here on Earth, or manufacturing capabilities in space that you are not able to do in gravity well.
NASA tracking 23,000 pieces of orbital debris 10 centimeters (almost 4 Inches or bigger.
However Bridenstine said India's test was conducted enough enough that "over time, this (debris) will all dissipate, "with the ISS and all the astronauts are on board safe.
