The Rosetta mission orbited and landed modules on the comet 67P/Churyumov–Gerasimenko. It launched in 2004 and performed flybys of Earth, Mars and asteroids before entering hibernation and waking to approach the comet in 2014. In November 2014, the Philae lander separated from Rosetta and landed on the comet, where it conducted science measurements for 3 days before losing power. Rosetta continued orbiting and observing the comet.
![In Orbit around 67P/C-G!
• In August 2014, Rosetta rendezvoused with the comet,
commencing an approach to it on a triangular path
whose segments are hyperbolic escape trajectories,
alternating with thruster burns.
• After closing to within about 30 km (19 mi) from the
comet the spacecraft will enter actual orbit about
it,[7][8] in preparation for releasing a lander that will
make contact with the comet itself.
• The exact surface layout of the comet is currently
unknown and the orbiter has been built to map this
before detaching the lander. It is anticipated that a
suitable landing site can be found, although few
specific details exist regarding the surface](https://image.slidesharecdn.com/rosettamission-toslideshare-141111142648-conversion-gate01/85/Rosetta-mission-60-320.jpg)

November 2014
• The lander, named Philae, will approach Churyumov–
Gerasimenko at relative speed around 1 m/s (2.2 mph;
3.6 km/h) and on contact with the surface,
two harpoons will be fired into the comet to prevent the
lander from bouncing off.
• Additional drills are used to further secure the lander on
the comet.
• After its attachment to the comet, expected to take place in
November 2014, the lander will begin its science mission:
– Characterisation of the nucleus
– Determination of the chemical compounds present,
including enantiomers[34]
– Study of comet activities and developments over time](https://image.slidesharecdn.com/rosettamission-toslideshare-141111142648-conversion-gate01/85/Rosetta-mission-83-320.jpg)

- 16. Rosetta has massive solar wings to power the spacecraft. They were unfurled and checked out at the European Space Agency's test facilities before being packed up for liftoff.
- 18. Rosetta's mission started on March 2, 2004, when it was launched on a European Ariane 5 rocket from Kourou, French Guiana.
- 22. Deep space manoeuvres • To achieve the required velocity to rendezvous with 67P/C-G, Rosetta used gravity assist manoeuvres to accelerate throughout the Inner solar system
