Asteroid deflection campaign design integrating epistemic uncertainty
Planetary defense, or asteroid collision avoidance, has been gaining interest with recent meteor or fly-by events, including the Chelyabinsk meteor that entered the Earth's atmosphere and exploded over Russia in 2013. Past or planned robotic missions to near-Earth asteroids are expected to provide …

Asteroid deflection and active debris removal methods with spaceborne lasers
Several deflection methods have been proposed over the years to mitigate the risk of impact between an asteroid and the Earth. Most of the strategies proposed fall into two categories: impulsive and slow-push. Impulsive strategies are usually modelled with an instantaneous change of momentum given …

Asteroid hazard mitigation: deflection models and mission analysis
… and evolution of the solar system. Among all asteroids, NEOs have stepped into prominence because of two important aspects: they are among the easiest celestial bodies to reach from Earth, in some cases with less demanding trajectories than a simple Earth-Moon trajectory and, even more …

Design and modeling of kinetic impact missions for deflecting near-earth asteroids
The solar system is full of small bodies such as asteroids and comets that are thought to be remnants of early planetary formation. As of June 2025, there are more than 1.4 million known small bodies in the solar system, more than 4,000 of which are classified as comets. These objects routinely …
