TEHRAN, Mar 27 -The comments came a day after India said it used an indigenously developed ballistic missile interceptor to destroy one of its own satellites at a height of 300 km (186 miles), in a test aimed at boosting its defenses in space.

India says space debris from anti-satellite test to 'vanish' in 45 daysTEHRAN, Young Journalists Club (YJC) -Critics say such technology, known to be possessed only by the United States, Russia and China, raises the prospect of an arms race in outer space, besides posing a hazard by creating a cloud of fragments that could persist for years.

G. Satheesh Reddy, the chief of India’s Defence Research and Development Organisation, said a low-altitude military satellite was picked for the test, to reduce the risk of debris left in space.

“That’s why we did it at lower altitude, it will vanish in no time,” he told Reuters in an interview. “The debris is moving right now. How much debris, we are trying to work out, but our calculations are it should be dying down within 45 days.”

Few satellites operate at the altitude of 300 km, from which experts say the collision debris will fall back to earth, burning up in the atmosphere in a matter of weeks, instead of posing a threat to other satellites.

In 2007, China destroyed a satellite in a polar orbit, creating the largest orbital debris cloud in history, with more than 3,000 objects, according to the Secure World Foundation.

Because the impact altitude exceeded 800 km (500 miles), many of the resulting scraps stayed in orbit. “Some of it could still be there,” Reddy said, adding that India had been much more careful in conducting its test.
