Breakthrough Starshot is a comprehensive space program launched under the US $100 million Breakthrough Initiatives, announced by Yuri Milner and Stephen Hawking to develop and launch practical interstellar space missions.
The program aims to demonstrate proof of concept for light-propelled spacecraft that could fly at 20 per cent of light speed.
Its main objective is to send one-gram chips to star systems beyond the solar system in search of extraterrestrial intelligence.
