  4. 4. ROSETTA EQM
  5. 5. This photo shows Rosetta being tested before it was wrapped in insulating blankets and loaded on a rocket for launch.
  6. 6. 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.
  7. 7. Rosetta's mission started on March 2, 2004, when it was launched on a European Ariane 5 rocket from Kourou, French Guiana.
  8. 8. 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
  9. 9. February 2007 Rosetta took this image of Mars as it looped through the solar system

  13. 13. November 2009 Rosetta snapped this image of Earth in November 2009. The spacecraft was 393,328 miles from Earth.
  14. 14. Beautiful Lutetia 10 July 2010 • Flew by and photographed the asteroid 21 Lutetia.

  32. 32. Stunning close up detail focusing on a smooth region on the ‘base’ of the ‘body’ section of comet 67P/Churyumov-Gerasimenko. The image was taken by Rosetta’s OSIRIS narrow-angle camera and downloaded today, 6 August. The image clearly shows a range of features, including boulders, craters and steep cliffs. The image was taken from a distance of 130 km and the image resolution is 2.4 metres per pixel.
  33. 33. .
  34. 34. 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

  51. 51. PHILAE’S INSTRUMENTS
  52. 52. Philae lander 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
