Russian billionaire devotes $100 million to star flight initiative | Spaceflight Now

Russian billionaire Yuri Milner plans to spend $100 million over the next few years to begin developing the technology needed to build a giant laser array to propel swarms of postage stamp-size spacecraft off on 20-year-long interstellar flights to Alpha Centauri, the nearest star system to the sun, the internet investor announced Tuesday.

The tiny 1-gram nanocraft, or “StarChips,” would be equipped with small, ultra-thin light sails and accelerated, one at a time, to 20 percent the speed of light by a powerful half-mile-wide array of ground-based lasers, boosting them to a cruise velocity of some 37,200 miles per second in a few minutes.
