Aiming for Alpha Centauri with Light-driven Nanocraft

Some people say we’re living through a golden age of science fiction and fantasy, and I for one agree. I’d also argue that we’re living through a golden age of science and exploration, especially of space.

Breakthrough Starshot is a new-to-me initiative whose aim is 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.”

Alpha Centauri would be reachable within a reasonable timeframe if unmanned space flight could reach 20 % of the speed of light. Ultra-light craft with solar sails could, they calculate, reach and fly by the system in just over 20 years.

The Breakthrough Initiatives were founded in 2015 by Yuri and Julia Milner to “explore the Universe, seek scientific evidence of life beyond Earth, and encourage public debate from a planetary perspective.”

Judging by their News section, however, Breakthrough Listen—which is “a $100 million program of astronomical observations in search of evidence of intelligent life beyond Earth” directed from UC Berkeley—is currently producing the most interesting results.

The board of Breakthrough Initiatives consists of three people as of this writing: Stephen Hawking, Mark Zuckerberg (yes, of the Facebook reputation), and Yuri Milner (an Israeli-Russian physicist, entrepreneur, and capitalist).

I must say that the initiative sounded more exciting to me prior to checking who the board are. Then again, who knows—after all, SpaceX has had its share of successes despite having essentially started as a millionnaire pet project. At least the Breakthrough Listen data is supposed to be open to the public.
