When China destroyed one of its own satellites in space six years ago, it alarmed many other Asia-Pacific countries that have invested heavily in orbiting satellites for telecommunications, Earth observation and scientific research.
China's action caused particular concern in the United States, Japan, Australia, India and other nations that use satellites for defense purposes that can include voice and data communications, surveillance, precise navigation and guidance of bombs and missiles.
In 2008, just over a year after the Chinese test, the U.S. fired a modified ballistic missile defense rocket from a warship to shoot down a malfunctioning American spy satellite about 250 km above the Pacific Ocean. Washington said that the operation was essential to prevent the bus-size craft and its toxic fuel from crashing back to Earth, possibly causing death, injury and damage.
