3. 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 mN/W), lasers can achieve a mass into space up to 40 times lower than an ion beaming system for the same deflection Dv

4. 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.
