霍金近日在其微博上宣布，启动突破摄行计划。原文摘录如下：
Greetings to everybody in China from NYC. At the One World Observatory in New York City, Yuri Milner and I launched a mission to the stars. Mark Zuckerberg lent his support by joining the board of our new initiative, Breakthrough Starshot.
Within the next generation, Breakthrough Starshot aims to develop a ‘nanocraft’ – a gram-scale robotic space probe – and use a light beam to push it to 20 percent of the speed of light. If we are successful, a flyby mission could reach Alpha Centauri about 20 years after launch, and send back images of any planets discovered in the system.
Albert Einstein once imagined riding on a light beam, and his thought experiment led him to the theory of special relativity. A little over a century later, we have the chance to attain a significant fraction of that speed: 100 million miles an hour. Only by going that fast can we reach the stars on the time-scale of a human life.
It is exciting to be involved in such an ambitious project, pushing the boundaries of ingenuity and engineering.

我在纽约向中国的各位问好！在纽约城的一号楼观景台，我和尤里·米尔纳启动了“突破摄星”计划 (Breakthrough Starshot)，马克·扎克伯格也加入了该计划的董事会，为“突破摄星”助一臂之力。
在一代人的时间内，“突破摄星”旨在研发出一台“纳米飞行器” —— 一台质量为克级的自动化太空探测器—— 并且通过光束把它推动到五分之一的光速。如果我们成功的话，这个飞掠任务将会在发射后二十年左右到达半人马座阿尔发星，并发送回来在那个星系中发现的行星的图片。
爱因斯坦曾经幻想在宇宙中乘着一道光线飞驰，这个思想实验为他的狭义相对论奠定了基础。一个多世纪后，我们有机会可以达到光速的一小部分：一亿英里每小时。只有通过这么快的速度，我们才有希望在人类的时间尺度内到达那些恒星。
这个项目耗资巨大，雄心勃勃地希望探索人类创新和工程学的极限。能参与这样的项目，非常令人兴奋。
