(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 panels 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.
