Asteroid Impact Risks

The book investigates the frequency and mechanics of impact events, detailing their potential consequences for Earth. For example, the Chicxulub event, which led to the extinction of the dinosaurs, serves as a stark reminder of what can happen.

The book progresses from the basic science of asteroids and comets to the current state of near-Earth object (NEO) detection efforts. It emphasizes the importance of continued investment in NEO detection, asteroid deflection, and space missions. Readers will discover the capabilities of ground-based telescopes and space-based observatories in tracking NEOs.

Furthermore, it delves into various planetary defense strategies, such as kinetic impactors and gravity tractors, while also addressing the ethical and political considerations surrounding these initiatives.
