Asteroid Deflection by Leveraging Rotational Self-Energy
A novel concept for the deflection of rotating asteroids is presented, based on the conversion of the asteroid rotational kinetic energy into translational kinetic energy. Such conversion is achiev...
The Cosmic Impact Hazard
Recognition of the hazard to life and property from impacts of comets and asteroids is currently leading to technical efforts to understand this hazard, estimate the resulting risk and plan for…
Small Landers and Separable Sub-Spacecraft for Near-term Solar Sails
TLDR
Advantages and constraints of small sub-spacecraft are discussed, focusing on emerging areas of activity such as asteroid diversity studies, planetary defence, and asteroid mining, on the background of the projects PHILAE, MASCOT, MASCot2, the JAXA-DLR Solar Power Sail Lander Design Study, and others.
Small spacecraft in small solar system body applications
In the wake of the successful Philae landing on comet 67P/Churyumov-Gerasimenko and the launch of the first Mobile Asteroid Surface Scout, MASCOT, aboard the Hayabusa2 space probe to asteroid…
SISIS ABSTRACT Over the past 20 years a small group of astronomers and planetary
scientists has actively promoted the idea that an asteroid might collide with the Earth and destroy civilization. Despite concerns about placing weapons in space, the asteroid scientists repeatedly…
Scale-dependent measurements of meteorite strength: Implications for asteroid fragmentation
Revisiting the deflection dilemma
The paper explores potential risks associated with expected growth of Near Earth Objects mining. It revisits the original dilemma posited by Carl Sagan and others in 1990s. The original dilemma was a…
