Model answer:

Giotto: flew close to Halley's Comet in 1986 and returned the first close pictures of a comet nucleus.
Huygens: the probe that descended to Titan, Saturn's largest moon, in 2005; generally described as the first landing in the outer Solar System.
Mars Express: ESA's first mission to another planet; an orbiter that reached Mars in late 2003 and kept working for many years.
Rosetta: orbited comet 67P in 2014, the first spacecraft to do so, and released the Philae lander, the first soft landing on a comet.

Partnership with NASA: Huygens, carried by NASA's Cassini as part of a joint mission with NASA and the Italian space agency.
