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.
