BACK IN THE 80S, I worked with a few analysts in box closets and a handful of specialists on a Pacific island who had figured out ways to hose satellites with different technologies. Normally, a pulse disables an overhead listening post. If you have the power, you could blast a satellite from the ground or above its orbit from a killer bird. Lots of different ways exist to punch things around the earth. The Chinese have fielded an antisatellite capability that destroyed an aging weather satellite last week. Weather satellites orbit higher than US spy satellites. Arms control experts told the New York Times that the Chinese accomplishment "could foreshadow an antisatellite arms race". No news there. The race started two years ago, when the US inadvertently sold the Chinese computing hardware arrays that could be used for advanced telemetry analysis.
