Using Lasers in Space: Laser Orbital Debris Removal and Asteroid Deflection

En savoir plus sur le livre

Orbital debris measuring 1 to 10 centimeters poses a serious threat to space vehicles, as it can cause catastrophic damage despite being detectable. Current tracking methods are insufficient for effective avoidance. The study suggests leveraging technological advancements in adaptive optics to utilize a ground-based pulsed laser that could ablate debris, generating thrust for atmospheric reentry. A single laser facility could potentially clear all such debris within three years, making the proposed technology demonstration a cost-effective solution for debris removal from Earth's orbit.
