Space Weathering on Near-Earth Objects investigated by neutral-particle detection
C. Plainaki, A. Milillo, S. Orsini +8
The ion-sputtering (IS) process is active in many planetary environments in the Solar System where plasma precipitates directly on the surface (for instance, Mercury, Moon, Europa)…
Threat Mitigation: The Gravity Tractor
Russell Schweickart, Clark Chapman, Dan Durda +1
The Gravity Tractor (GT) is a fully controlled asteroid deflection concept using the mutual gravity between a robotic spacecraft and an asteroid to slowly accelerate the asteroid i…
Threat Mitigation: The Asteroid Tugboat
Russell Schweickart, Clark Chapman, Dan Durda +1
The Asteroid Tugboat (AT) is a fully controlled asteroid deflection concept using a robotic spacecraft powered by a high efficiency, electric propulsion system (ion or plasma) whic…
Threat Characterization: Trajectory Dynamics
Russell Schweickart, Clark Chapman, Dan Durda +3
Given a primary interest in "mitigation of the potential hazard" of near-Earth objects impacting the Earth, the subject of characterization takes on an aspect not normally present…
