A constellation of sixty Earth-observation satellites, each designed for a 3-year mission, planned by BlackSky Global, of Seattle, Washington, USA, the first of which, a pathfinder microsatellite, was launched on 26 September 2016, from the Satish Dhawan Space Centre, India, into a Sun-synchronous orbit. The company aimed to have the full constellation in orbit by 2019. The satellites will provide 1-m-resolution colour images of the entire Earth.
