Launching a fleet of nano-probes toward nearest star

posted by Jason Kottke   Apr 12, 2016

Russian billionaire Yuri Milner, with the help of Stephen Hawking and Mark Zuckerburg, plans to launch a fleet of nano-probes1 toward a star close to our solar system, Alpha Centuri. The craft, outfitted with lightsails, will be pushed along to their destination in just 20 years by powerful lasers on Earth.

In the last decade and a half, rapid technological advances have opened up the possibility of light-powered space travel at a significant fraction of light speed. This involves a ground-based light beamer pushing ultra-light nanocrafts - miniature space probes attached to lightsails - to speeds of up to 100 million miles an hour. Such a system would allow a flyby mission to reach Alpha Centauri in just over 20 years from launch, and beam home images of possible planets, as well as other scientific data such as analysis of magnetic fields.

Breakthrough Starshot aims to demonstrate proof of concept for ultra-fast light-driven nanocrafts, and lay the foundations for a first launch to Alpha Centauri within the next generation. Along the way, the project could generate important supplementary benefits to astronomy, including solar system exploration and detection of Earth-crossing asteroids.

The Atlantic and the NY Times have more information on the initiative.

  1. Sure, we can launch laser-powered nano-probes toward a distant star, but humanity still struggles with proper descriptive URLs.
