2007

The Three Components of Protection of the Earth from NEO Impacts Early Warning Proven Deflection Capability International Decision-making Protocol

Early Warning Spaceguard 1 & 2 (Comparable Numbers) Target Population 1,000 80,000 71% completed ,000 Total Discovered 4, ,000 Potential Impactors – 10,000(?)

Kinetic Impact Pushes the asteroid via direct impact Current Deflection Capability Gravity Tractor Pulls the asteroid using mutual gravity as a tow- rope

Nuclear Explosion Explodes surface off NEO to create impulsive push

Earth orbital path NEO orbital path line of nodes

Path of Risk for Apophis

Paths of Risk for NEOs of Concern

The End Q&A
