Rosetta (ESA)

Ariane 5 Launch of Rosetta spacecraft

Rosetta is a European Space Agency-led robotic spacecraft mission launched in 2004 intended to study the comet 67P/Churyumov-Gerasimenko. Rosetta consists of two main elements: the Rosetta space probe and the Philae lander. The probe is named after the Rosetta Stone, as it is hoped the mission will help unlock the secrets of how our solar system looked before planets formed. The lander is named after the Nile island Philae where an obelisk was found that helped decipher the Rosetta Stone.
