>> Europe's Rosetta Space Probe is about to go out with a bang. After 12 years in space and a voyage covering 6 billion kilometers, it's days away from crashing into a comet and that's no accident. Rosetta has already studied Comet 67P in detail. Now scientists will use the probe's final moments to get some very close up pictures and sensor readings.
Reuters correspondent Victoria Brian is following the mission.>> Rosetta spacecraft has been orbiting around the comet, but hasn't been that close because of the irregular polar gravity when it get so close to the comet. Sending Rosetta down to the surface of the comet will allow Rosetta's instruments to take more valuable data and the scientists will be able to use that to examine how gases get from the surface of the comet to the outer atmosphere.
>> In 2014, Rosetta managed to put a lander down on the comet's surface. It bounced off and then got wedged in a dark crevice but still sent back useful data. Some of Rosetta's discoveries could change ideas about the origins of life.>> The data gleaned from Rosetta and compared with other comet missions, makes them believe asteroids were the main bringers of water to the Earth.
They think that comets however brought proteins and other organic molecules to Earth. And that these proteins and molecules formed the building blocks for life on Earth.
>> Back on our home planet, the mission's dramatic end is also having an unexpected cultural impacts. Legendary Greek musician, Vangelis, bringing out a new album Friday to mark the occasion. It's simply titled Rosetta.
