摘要

With the US reportedly preparing to reveal the existence of a previously secret space weapon programme, there is naturally a great deal of speculation about the kind of weapon it could be. The most spectacular are hard-kill missiles launched from aircraft, ground systems or naval vessels, capable of obliterating any satellite whose orbit they can reach. Such weapons, however, are inevitably messy, as they create fast-moving, high energy debris that can threaten other spacecraft in nearby or intersecting orbits. The ultimate worry is the Kessler Syndrome (named for NASA scientist Donald J Kessler who first described the danger in 1978) in which debris collisions create more debris in a cascade of destruction that wrecks every human-made object in orbit and effectively renders space unusable for an extended period. There are much more subtle options, however, and it is possible that the about-not-to-be-secret-any-more US weapon is one of them.
