I wanted to flaga story from Inside the Pentagon about whether the Chinese are aiming to interfere with U.S. military space capabilities.
The article quotes U.S. Strategic Command Chief Gen. James Cartwright as saying that China has not yet actually interfered with U.S. operations in space. However, it's also clear from the article that U.S. military officials believe China is actively pursuing weapons that could be used to counter U.S. space-based capabilities, upon which the modern military heavily relies for communications, navigation and intelligence gathering.
The article is timely because the Bush administration recently released a new National Space Policy that defines how the United States aims to use space both militarily and commercially. A summary of the document is available here (.pdf file), from the White House Office of Science and Technology Policy.
