The Rosetta spacecraft ended its historic mission on Friday, crashing on the surface of the dusty, icy comet it has spent 12 years chasing in a hunt that has provided insight into the early days of the solar system and captured the public's imagination.
The spacecraft has stalked comet 67P/Churyumov–Gerasimenko across more than 6 billion km (3.7 billion miles) of space, collecting a treasure trove of information on comets that will keep scientists busy for the next decade.
