Breakthrough Starshot has successfully launched its first spacecraft, marking a major milestone for interstellar exploration and the search for life beyond our solar system.

The ‘Sprites,’ which reached low-Earth Orbit on June 23, are the smallest fully functional space probes ever made, with each built on a single circuit board measuring just 1.4-by-1.4 inches (3.5-by-3.5cm).

With the launch of the prototype Sprites, the initiative has brought spacecraft miniaturization closer to reality, and, in turn, its ultimate goal of sending a fleet of tiny, light-propelled ‘StarChips’ to our closest stellar neighbour, Alpha Centauri.
