Asteroidal impact threats to the Earth may be predicted a century or more in advance. Several methods of mitigating these threats have been proposed. Here I evaluate changing an asteroid’s albedo to change the Solar radiation pressure force, and hence its orbit. Albedo may be increased to near-unity by applying a thin (∼0.1μ\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage… 



A mission template for exploration and damage mitigation of potential hazard of Near Earth Asteroids

The Apophis Exploratory and Mitigation Platform (AEMP) concept was developed as a prototype mission to explore and potentially deflect the Near Earth Asteroid (NEA) 99942 Apophis. Deflection of the

Gravitational tractor for towing asteroids

A spacecraft that can controllably alter the trajectory of an Earth-threatening asteroid by using gravity as a towline is presented, which is insensitive to the structure, surface properties and rotation state of the asteroid.


Two classes of solid bodies large enough to be detected by telescopes occur in orbits that overlap that of the Earth. These bodies are the Earth-crossing asteroids and comet nuclei. Although their

A permanently-acting NEA damage mitigation technique via the Yarkovsky effect

In the later stages of a combined mission of exploration and damage mitigation of a hazardous Near Earth Asteroid (NEA), sufficiently detailed tracking, orbit prediction, mass distribution, and

The flux of small near-Earth objects colliding with the Earth

Satellite records of bolide detonations in the atmosphere over the past 8.5 years are reported and it is found that the flux of objects in the 1–10-m size range has the same power-law distribution as bodies with diameters >50 m.

NEO Population, Velocity Bias, and Impact Risk from an ATLAS Analysis

We estimate the total population of near-Earth objects (NEOs) in the solar system using an extensive, “solar-system-to-pixels” fake-asteroid simulation to debias detections of real NEOs by the ATLAS
