China’s 11 January 2007 test of a sophisticated anti-satellite weapon has caused a great deal of concern with some analysts predicting the start of an arms race in space while others have tried to minimize its significance. Using the pattern of debris created by the test, this talk will describe the weapon’s capabilities: including it being a hit-to-kill weapon, its most likely mass, and guidance and control capabilities, and its ability to attack satellites at all altitudes; its limitations: it uses visible light and not infrared, deep-space attacks will be severely limited by available launch pads, and the long warning time such an attack would give the US. The talk will also report on the results of a “war game” of an all out Chinese attack on US space assets. The bottom line of that analysis indicates that not only could the US ride out such an attack but it could avoid loosing any of its strategically important communications or navigation satellites.

Geoffrey Forden has been at MIT since 2000 where his research includes the analysis of Russian and Chinese space systems as well as trying to understand how proliferators acquire the know-how and industrial infrastructure to produce weapons of mass destruction. In 2002-2003, Dr. Forden spent a year on leave from MIT serving as the first Chief of Multidiscipline Analysis Section for UNMOVIC, the UN agency responsible for verifying and monitoring the dismantlement of Iraq's weapons of mass destruction. Prior to coming to MIT, he was a strategic weapons analyst in the National Security Division of the Congressional Budget Office after having spent a year at CISAC as a Science Fellow, a time he still looks back upon as a very happy and productive experience. Dr. Forden holds a PhD in physics.
