摘要

Last March, India became only the fourth country in the world-arter Russia, the US, and China-to successfully destroy a satellite in orbit. Mission Shakti, as it was called, was a demonstration of a direct-ascent anti-satellite weapon (ASAT)-or in plain English, a missile launched from the ground. Typically this type of ASAT has a "kill vehicle," essentially a chunk of metal with its own guidance system, mounted on top of a ballistic missile. Shortly after the missile leaves the atmosphere, the killvehicle detaches from it and makes small course corrections as it approaches the target. No explosives are needed; at orbital speeds, kinetic energy does the damage. The idea of shooting down satellites has been around as long as satellites have. The first (failed) ASAT test, by the US, was back in 1958, just two years after the launch of Sputnik. During the Cold War, the US and the Soviets both developed sophisticated anti-satellite weaponry. The US had missiles that could be launched from fighter jets (successfully tested in 1985) as well as nuclear-tipped missiles capable of obliterating enemy satellites. China's own first successful ASAT test was in 2007.
