Rosetta, European Space Agency spacecraft that carried Philae, the first space probe to land on a comet. Rosetta was launched on March 2, 2004, by an Ariane 5 rocket from Kourou, French Guiana, on a 10-year mission to Comet 67P/Churyumov-Gerasimenko. The
The picture taken with the navigation camera on Rosetta and released by the European Space Agency ESA shows a raised plateau on the larger lobe of Comet 67P/Churyumov–Gerasimenko. It was captured from a distance of 9.8 km from the center of the comet (7.8 km / 4.8 miles from the surf...
In this paper, we continue previous work on the estimation of surface strength and try to narrow the bounds on this on respective parameters. We also outline the rationale for our estimation on the min/max outgassing rates for 67P/Churyumov-Gerasimenko, the target of the Rosetta mission, ...
Human kind did something incredible yesterday: we landed something on the surface of a comet. After a 10 year journey to Comet 67P/Churyumov–Gerasimenko,

From these considerations, a consistent picture of the spatial distribution of dusty materials across the surface of comet 67P as it moves around the perihelion can be developed. It is found that because of the redeposition of the ejected dust from the Southern hemisphere to the Northern ...
We perform numerical simulations to show that the ambient dust coma is driven by pervasive but non-uniform water outgassing from the homogeneous surface layer. Physical collimations of gas and dust flows occur at local maxima of insolation and also via topographic focusing. Coma structures are ...
On Nov. 12, the European Space Agency's Rosetta spacecraft and Philae lander made history. The lander successfully made it to the surface of Comet 67P/Churyumov-Gerasimenko. Scientists confirmed the landing at a little bit after 11 a.m. EST (1600 GMT).See the latest landing photos!
In August 2014, ESA's Rosetta Spacecraft will rendezvous with Comet 67P/Churyumov-Gerasimenko and deploy the Philae lander. See photos from the Rosetta comet probe.
