So all those questions about arming space have been answered now……

The stunning image of a Navy missile streaking into outer space at 6,000 mph to obliterate an orbiting spy satellite boosts the credibility of missile-defense advocates. Yet questions remain whether that success could be duplicated against a surprise, real-world attack.

The idea, whether the target is an unarmed satellite or an enemy missile, is basically the same: fire a guided missile into the path of the moving target and smash it to bits by the force of impact. In theory, the collision could render harmless even a nuclear- or chemical-armed missile, an idea that evolved from President Reagan’s “star wars” program of the 1980s.
