Asteroid laser ablation is a proposed method for deflecting asteroids, involving the use of a laser array to alter the orbit of an asteroid. Laser ablation works by heating up a substance enough to allow gaseous material to eject, either through sublimation (solid to gas) or vaporization (liquid to gas). For most asteroids this process occurs ...
For such a prompt deflection of the larger NEOs, 1.3 to 2.2 km (0.8 to 1.4 mi), the required collector sizes are comparable to the target diameter. In the case of a longer warning time, the required size of the collector may be significantly decreased. Artist's impression of asteroid deflection using an innovative ring-array solar collector.

Avoidance coping is measured via a self-reported questionnaire. Initially, the Multidimensional Experiential Avoidance Questionnaire (MEAQ) was used, which is a 62-item questionnaire that assesses experiential avoidance, and thus avoidance coping, by measuring how many avoidant behaviors a person exhibits and how strongly they agree with each statement on a scale of 1–6.
