But DE-STAR 4 \u2013 at 10 kilometers in diameter, about 100 times the size of the ISS \u2013 could deliver 1.4 megatons of energy per day to its target, said Lubin, obliterating an asteroid 500 meters across in one year.<\/p>\n<p>The speed of interplanetary travel \u2013 far beyond what is possible with chemical propellant rockets used today \u2013 could be increased with this sized system, according to Lubin. It could also power advanced ion drive systems for deep space travel, he said. Able to engage multiple targets and missions at once, DE-STAR 4 \u201ccould simultaneously evaporate an asteroid, determine the composition of another, and propel a spacecraft.\u201d<\/p>\n<p><!-- Link: <a href=\"http:\/\/www.nextbigfuture.com\/2014\/10\/destar-phased-array-laser-systems-for.html?m=1\">http:\/\/www.nextbigfuture.com\/2014\/10\/destar-phased-array-las...r.html?m=1<\/a> --><\/p>\n","protected":false},"excerpt":{"rendered":"<p>A laser phased array directed energy system has been designed and simulated.
