The Asteroid Threat: Defending Our Planet from Deadly Near-Earth Objects
William E. Burrows
Presents a practical, manageable plan for defusing a in all probability deadly probability from a rogue asteroid or comet.
The explosion of a big meteor over Chelyabinsk, Siberia, in February 2013 is simply the newest reminder that planet Earth is at risk of harmful and probably catastrophic collisions with area particles of assorted types. during this informative and forward-looking e-book, veteran aerospace author William E. Burrows explains what we will be able to do sooner or later to prevent way more severe affects from "Near-Earth items" (NEOs), as they're known as within the planetary safeguard neighborhood. The excellent news is that humanity is now built with the complicated know-how essential to devise a long term technique to defend the planet. Burrows outlines the subsequent key beneficial properties of an efficient planetary safeguard strategy:
* a robust house surveillance procedure able to recognizing a major risk from area at the very least twenty-five years in advance
* an area craft "nudge" that may throw a collision-course asteroid off course lengthy earlier than it poses the specter of coming near near impact
* A guns approach for use as a last-ditch strategy to blast an NEO should still all else fail.
The writer notes the numerous advantages for international balance and extending overseas cooperation caused by a united around the world attempt to guard the planet.
Combining realism with an positive can-do angle, Burrows exhibits that humanity is able to overcoming a in all probability calamitous state of affairs.
