Rosetta’s orbit around the comet

(0)

After a ten year journey through space, ESA’s Rosetta spacecraft will reach comet 67P/Churyumov-Gerasimenko in August 2014. After catching up with the comet Rosetta will slightly overtake and enter orbit from the ‘front’ of the comet as both the spacecraft and 67P/CG move along their orbits around the Sun. Rosetta will carry out a complex series of manoeuvres to reduce the separation between the spacecraft and comet from around 100 km to 25-30 km. From this close orbit, detailed mapping will allow scientists to determine the landing site for the mission’s Philae lander. Immediately prior to the deployment of Philae in November, Rosetta will come to within just 2.5 km of the comet’s nucleus.
This animation is not to scale; Rosetta’s solar arrays span 32 m, and the comet is approximately 4 km wide.

  2. Are each of those "triangle bends" thrust achieved course corrections, or are those accomplished more by gravity? Because if those are purely RCS corrections — that seems like a lot of fuel to me.

  3. This is the coolest thing to happen in a long time. ?Hopefully we will get full disclosure and the truth about the information gained. ?Unless it compliments the current science, I sincerely doubt it. ?Sadly.

  4. Their was something here before us. Some how it exploded pieces are now on their return . Just hope we are not in its actual orbit. BECAUSE it will hit us and knock this planet out of orbit for a while. Everybody will die.

  5. Este projecto ensina-nos tamb?m que n?o se deve ter medo de arriscar que n?o devemos ter inseguran?a pelo desconhecido!! Emocionante se ? permitido sondar e nas tantas voltas teve a capacidade de transformar e poder ir al?m …muito mais al?m!!?
