California Scientists Propose System To Vaporize Asteroids That Threaten Earth


An asteroid roughly half as large as a football field –– and with energy equal to a large hydrogen bomb –– recently buzzed by Earth at close range. Someday, a threat of that size could be eliminated within an hour under a proposed system just unveiled by two California scientists. The same system could destroy asteroids 10 times larger than that known as 2012 DA14 in about a year, with evaporation starting at a distance as far away as the Sun.

UC Santa Barbara physicist and professor Philip M. Lubin, and Gary B. Hughes, a researcher and professor from California Polytechnic State University, San Luis Obispo, conceived DE-STAR, or Directed Energy Solar Targeting of Asteroids an exploRation, as a realistic means of mitigating potential threats posed to the Earth by asteroids and comets.

Described as a “directed energy orbital defense system,” DE-STAR is designed to harness some of the power of the sun and convert it into a massive phased array of laser beams that can destroy, or evaporate, asteroids posing a potential threat to Earth.
