The threat of an asteroid hitting our home planet may not an immediate one, but it better be tackled before it becomes imminent. The brief visit of the 99942 Apophis asteroid in 2004 served as a reminder that a collision with Earth is by all means possible. Scientists have been working on a solution since then, and several bold plans were hatched. The latest one comes from Massimiliano Vasile and Christie Maddock from the University of Strathclyde in Scotland, who reckon we should build a spacecraft fitted with solar-powered lasers.
