With a couple of extreme events up as of late, it may perhaps be wise to start taking some defensive measures for unwanted stuff that may pass through our beloved mother earth.
First it was the meteor shower which hit Russia and then there was that other one which passed Earth. So how do we defend asteroids and other stuff considering the size and potential damage it can render given its unexpected coming?
Well a couple of scientists over at the University of California at Santa Barbara may have a solution, solar powered lasers. The laser could alter the course of future incoming asteroids or better yet, vaporize it completely.
The solar powered laser is called the DE-STAR (Directed Energy Solar Targeting of Asteroids). The system would harness solar power and channel it into a phase of arrayed lasers.
According to the scientists who have been working on the DE-STAR project for a year, the system could be developed in different sizes. Estimates suggest that DE-STAR 2 could destroy an asteroid 10 times the size of 2012 DA14 which missd us by about 17,100 miles last Friday. DE-STAR 6 could function both as an orbiting power source and propulsion system, allowing for interstellar travel.
