Why kinetic impactors are not always the best option? It can be demonstrated that for the mass fraction that actually impact the asteroid is theoretically 1 while for shallow crossers can be as low as 0.1 for the same impact velocity. Can we make nuclear blasts reliable and controllable? The nuclear cycler is a new concept that provides enhanced controllability and reliability with 15% loss in efficiency Can lasers be a solution? With a thrust coupling of over 35 mN/W (an ion beam gives 20-40 mN/W), lasers can achieve a mass into space up to 40 times lower than an ion beaming system for the same deflection Dv

New observation and detection orbits for Aitra asteroids. Equipped with a payload equivalent to NEOSSat, a small 700kg spacecraft can improve the ephemerides of 7 Atira asteroids and detect 3 new Atira per observation. Understanding the re-entry process. Are current predictions meaningful? Multipoint simulation and evaluation of asteroid re-entry scenarios.
