"The Chinese military used a ground-based missile to hit and destroy one of its aging satellites orbiting more than 500 miles in space last week -- a high-stakes test demonstrating China's ability to target regions of space that are home to U.S. spy satellites and space-based missile defense systems. The test of anti-satellite technology is believed to be the first of its kind in two decades by any nation and raised concerns about the vulnerability of U.S. satellites and a possible arms race in space. China's action drew sharp protests from other nations with satellite programs -- a predictable response that experts said dramatically illustrates Chinese willingness to face broad international criticism when it comes to space, which Beijing considers a key part of the push to modernize its military and increase its ability to compete in high-tech warfare. "The U.S. believes China's development and testing of such weapons is inconsistent with the spirit of cooperation that both countries aspire to in the civil space area," National Security Council spokesman Gordon Johndroe said yesterday. "We and other countries have expressed our concern regarding this action to the Chinese."
