原文影片請看此 著名科學家、矽谷菁英、億萬富翁組成最強團隊，打造可穿越星際，郵票大小的奈米太空船（nanocraft）。 聽起來好像007電影的三流劇情嗎？若真拍成電影的話，007現在可有得忙了。 這團隊是由頂尖科學家，史帝芬霍金博士（Dr. Stephen Hawking）、俄國億萬富翁米爾納（Yuri Milner）、臉書公司創辦人馬克祖克柏（Mark Zuckerberg）三人組成。 這艘星際旅行奈米太空船裝載的所有科技－包括攝影機，都在一張郵票大小的晶片中。 這張「星晶片」（starchip）結合光帆（light sail），形成一艘奈米太空船。光帆可接收從地球發射的雷射光束，作為推進力。 雷射光來自地球上，一英哩寬的雷射陣列，該陣列可能設於南美洲阿他加馬沙漠（Atacama Desert）海拔高度約4公里處。 雷射陣列需發送十億瓦（100 gigawatt）光能，研究團隊計畫發送奈米太空船艦隊，到離地球最近的「半人馬座阿爾法星系」（Alpha-Centauri）。 若計畫成功，奈米太空船將以雷射光作為推進力，以1/5光速（秒速6萬公里）前進。 以如此高速，奈米太空船只需幾十年，就可到達離地球40兆公里的「半人馬座阿爾法星系」。而以目前的太空航行技術，則須數千年。 本計畫名為「突破星擊」（Breakthrough Starshot），俄國富商米爾納投資約一億美元。 然而本計畫可能需斥資百億美元，若此概念能實現，須耗時30年，才能讓第一批太空船升空。 英文原文： A hit team of renowned scientists, Silicon Valley elites and a billionaire businessman have come together to launch a fleet of postage stamp-sized interstellar spacecraft. Sounds like the pitch for a bad Bond movie, right? Well if it was, 007’d have his hands full. Because this team includes scientist supreme, Dr. Stephen Hawking, Russian billionaire Yuri Milner and Facebook founder Mark Zuckerberg. All technology — including the camera — for the tiny interstellar spacecraft would be placed inside a postage-stamp-sized chip. Called a starchip, this device would come with a light sail to form a nanocraft. This sail has a surface that would use Earth-based laser light to propel it along. The lasers would come from a mile-wide laser array potentially situated 13,000 feet above sea level in the Atacama Desert in South America. Using light energy from the 100 gigawatt laser array, the team plans to send a fleet of these nanocrafts to our closest star system, Alpha-Centauri. If successful, a nanocraft could travel at 20 percent of the speed of light, or 134.2 million miles per hour, using laser light propulsion. At that speed, a nanocraft could traverse the 25 trillion miles to Alpha Centauri in a matter of decades, while a current spacecraft would take thousands of years. Dubbed Breakthrough Starshot, Milner has invested around $100 million in the nanocraft concept. However, it will still potentially cost billions and could take up to 30 years to get a swarm of the devices into space if the concept is shown to be successful.
