Rosetta Crash Lands on Comet : Completes Mission

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.
●    The mission managed several historic firsts, such as getting a spacecraft into orbit around a comet and the unprecedented landing of a probe on the surface. 
●    A handful of previous spacecraft had snapped pictures and collected data as they flew past their targets.
●    The ESA is ending the mission because 67P is racing toward the outer solar system, out of range for the solar-powered spacecraft.
●    Rosetta also has been subjected to the harsh radiation and extreme temperatures of space since launching in March 2004 and so was unlikely to last too much longer.
●    Before reaching the surface and shutting down, Rosetta's instruments and camera relayed back data and images, giving scientists insight into the structure of the comet.
