What to do about bolts from the blue

Article Abstract:

Scientist say a preemptive defense for preventing a 'near-earth object' (NEO), such as an asteroid or a comet, from colliding with Earth is feasible. Such a potentially disastrous collision is said to be improbable but not impossible. The way envisioned to prevent it involves sending nuclear-armed rockets to intercept the incoming NEO as far away from the Earth as possible. The first thing that needs to be done is to establish a detection system. An example of such a system, called the Spaceguard Survey, was proposed in 1992.
