(space probe that visited a comet)

Rosetta was an European Space Agency space probe that rendezvoused with the Comet, 67P/Churyumov-Gerasimenko. It was launched in 2004 and reached the comet in 2014. A lander, Philae, landed in 2014 but failed to position its solar planes effectively and achieved only a couple of days' science activities. The Rosetta science mission continued until 2016 when the probe was deliberately hard-landed on the comet.
