How long did it take Rosetta to reach the comet?
The spacecraft arrived at the comet on 6 August 2014 following a 10-year journey through the Solar System. Between August and November 2014, the spacecraft orbited the comet and gathered data to characterise the environment and the comet nucleus. On 12 November 2014, Rosetta’s lander Philae was deployed to the surface.
What did Rosetta accomplish?
The Rosetta mission was the first to orbit (rather than just visit) a comet; the first to land a probe on a comet and, in its final moments, the first to conclude with a controlled comet crash-landing.
Is it possible to land on a comet?
Having far smaller mass than the Earth, the gravity on the surface of a comet is much lower than on Earth, and so landing in the traditional sense would not be possible as you would bounce off the surface.
When did Philae land on comet?
Don’t ask. The Philae lander, wedged underneath a rock, on comet 67P/Churyumov-Gerasimenko. Scientists have reconstructed its bumpy landing on the surface in 2014 for the first time.

What is Rosetta?
Rosetta was the first spacecraft to orbit a comet nucleus, and was the first spacecraft to fly alongside a comet as it headed towards the inner Solar System.
What is the resolution of the Rosetta composite image?
This composite is a mosaic comprising four individual NAVCAM images taken from 19 miles (31 kilometers) from the center of comet 67P/Churyumov-Gerasimenko on Nov. 20, 2014. The image resolution is 10 feet (3 meters) per pixel. Rosetta is an ESA mission with contributions from its member states and NASA.
How fast is Rosetta moving towards comet 67P?
After leaving its hibernation mode in January 2014 and getting closer to the comet, Rosetta began a series of eight burns in May 2014. These reduced the relative velocity between the spacecraft and 67P from 775 m/s (2,540 ft/s) to 7.9 m/s (26 ft/s).
