Rosetta was an ESA space probe. It went on a mission to study the comet 67P/Churyumov–Gerasimenko. The Rosetta mission had two parts: the Rosetta space probe and the Philae lander. The spacecraft was launched on 2 March 2004 by an Ariane 5 rocket. On 12 November 2014 Philae landed but soon lost electrical power and radio contact. Rosetta continued to examine the comet from orbit until 30 September 2016 when it landed.
