>> Scientists call it a rock and roll ending. Europe's Rosetta space probe crashing into comet 67P on Friday morning. It's a dramatic and deliberate end to the mission. Reuters' correspondent Victoria Bryan.>> Scientists will be looking for images of the sidewalls of the comet in order to ascertain how the structure of comets was formed.

In addition, the landing site has been chosen for its proximity to some 100 meter wide pits, a bit like sinkholes on Earth. Scientists hope that looking at these pits more closely will explain how gases and dust get from the surface of the comet to the outer atmosphere. Rosetta's epic journey captured the imagination, it traveled 6 billion kilometers over 12 years.

In 2014 it put a lander down on the surface of the comet. Now a dramatic end is the only option. At the moment, the comet is speeding away from the Sun, and that means that there is very little sun falling on Rosetta's solar panels in order to power the spacecraft.

>> This means that Rosetta is only transmitting data at about 10% of what it was last year.>> Scientists sad to say good-bye to Rosetta. They became attached to the plucky probe, but their work is far from done. Rosetta gathered more data than all other comet missions combined.

Digesting it all will take at least a decade.
