This week I learned about ‘Breakthrough Starshot’, which is a project that aims to launch a fleet of spacecraft to a neighbouring star by 2036. The spacecraft are tiny (about 1 centimeter large, not including their sails) and they’d carry miniature cameras and other equipment. The idea is that a swarm of these tiny spacecraft could be accelerated through space by huge lasers down on Earth. They would be able to reach the habitable planet Proxima Centauri b within 20 to 30 years. A truly amazing idea.
