Scientists for the Rosetta mission explain the origins of our solar system. The Rosetta spacecraft arrived at comet 67P/Churyumov Gerasimenko in August 2014 and dispatched the Philae lander to the surface in November. In 2015, the mothercraft continues to orbit and study the comet as it passes through the inner solar system for its closest approach to the sun in August.
