When was the spacecraft Rosetta launched to make contact with comet 67P/ChuryumovGerasimenko (67P)?
Rosetta (spacecraft) Rosetta (spacecraft) Rosetta was a space probe built by the European Space Agency launched on 2 March 2004. Along with "Philae", its lander module, "Rosetta" performed a detailed study of comet 67P/Churyumov–Gerasimenko (67P). During its journey to the comet, the spacecraft flew by Mars and the asteroids 21 Lutetia and 2867 Šteins. It was launched as the third cornerstone mission of the ESA's Horizon 2000 programme, after "SOHO""Cluster" and "XMM-Newton". On 6 August 2014, the spacecraft reached the comet and performed a series of manoeuvres to eventually orbit the comet at distances of . On 12 November, its lander module
Rosetta (spacecraft) allowed the four RWAs to operate throughout "Rosetta" mission at 67P/Churyumov–Gerasimenko despite occasional anomalies in their friction plots and a heavy workload imposed by numerous orbital changes. In August 2014, "Rosetta" rendezvoused with the comet 67P/Churyumov–Gerasimenko (67P) and commenced a series of manoeuvres that took it on two successive triangular paths, averaging from the nucleus, whose segments are hyperbolic escape trajectories alternating with thruster burns. After closing to within about from the comet on 10 September, the spacecraft entered actual orbit about it. The surface layout of 67P was unknown before "Rosetta" arrival. The orbiter mapped the comet in anticipation
