Rosetta

ESA's landmark comet mission — the first to orbit a comet nucleus and, via its Philae lander, the first to soft-land on one. It escorted comet 67P/Churyumov–Gerasimenko through perihelion for two years before its own controlled descent to the surface in 2016.

Targets & sample

Mission & science

Goals
Rendezvous with and orbit a comet, deploy a lander, and follow the nucleus through its active perihelion passage.
Engineering milestones
First comet orbiter; deployed the Philae lander (2014); ended with a controlled descent to 67P (2016).
Science discoveries
Mapped 67P's bilobed nucleus; measured a D/H ratio unlike Earth's oceans; detected molecular oxygen, glycine, and phosphorus.
Outcome
Complete success; a defining comet mission.
