Deflection Of An Asteroid By Laser Ablation And Laser Pressure Technique
The NEO deflection method employing laser ablation is an interesting and promising method to deviate the orbit of the asteroid. This technique employs trains of solar-pumped laser pulses, from a number of spacecrafts in specific formation, to ablate material from the asteroid surface. This process not only reduces the momentum of the asteroid by required amount but also creates a pressure in th...
متن کاملOrbital Simulations on Deflecting Near-Earth Objects by Directed Energy
Laser ablation of a near-Earth object (NEO) on a collision course with Earth produces a cloud of ejecta that exerts a thrust on the NEO, deflecting it from its original trajectory. Ablation may be performed from afar by illuminating an Earth-targeting asteroid or comet with a stand-off “DE-STAR” system consisting of a large phased-array laser in Earth orbit. Alternatively, a much smaller stand...

Laser ablation of a Near Earth Object (NEO) on a collision course with Earth produces a cloud of ejecta which exerts a thrust on the NEO, deflecting it from its original trajectory. The DE-STAR system provides thrust by illuminating an Earth-targeting asteroid or comet from afar with a stand-off system consisting of a large phased-array laser in Earth orbit. A much smaller version of the same s...
متن کاملOrbital Simulations for Directed Energy Deflection of Near-Earth Asteroids
Directed energy laser ablation at the surface of an asteroid or comet produces an ejection plume that will impart a thrust on the asteroid. This thrust can mitigate a threatened collision with the Earth. This technique uses the asteroid itself as the deflection propellant. The DESTAR laser system is designed to produce a sufficiently intense spot on the surface of an asteroid to accomplish this...
متن کاملEffective Planetary Defense using Directed Energy DE-STARLITE
We show that Directed Energy (DE) systems offer the potential for true planetary defense from small to km class threats. Directed energy has evolved dramatically recently and is on an extremely rapid ascent technologically. It is now feasible to consider DE systems for threats from asteroids and comets. DE-STAR (Directed Energy System for Targeting of Asteroids and exploRation) is a phased-arra...
