OTD in Space - September 30: Rosetta Spacecraft Crashes into a Comet

On Sept. 30, 2016, the European Space Agency's Rosetta spacecraft purposely crashed into a comet.

Rosetta launched in 2004 and spent 10 years chasing down Comet 67P, a rubber-duck-shaped space rock that orbits the sun between Earth and Jupiter. Rosetta spent the next two years tagging along with the comet as it traveled through the solar system. When it was time for the mission to end, Rosetta gently crashed into the comet.
