Fact Sheet

ESA's historic Rosetta mission concluded as planned, on 30 September 2016, with a controlled impact onto the comet it had been investigating for more than two years. The mission was launched on 2 March 2004, on a 10-year journey towards comet 67P/Churyumov-Gerasimenko. En route, it passed by two asteroids, 2867 Steins (in 2008) and 21 Lutetia (in 2010), before entering deep-space hibernation mode in June 2011. On 20 January 2014, it 'woke up' and prepared for arrival at the comet in August that year. On 12 November, the mission deployed its Philae probe to the comet, the first time in history that such an extraordinary feat was achieved. During the next phase of the mission, Rosetta accompanied the comet through perihelion (13 August 2015) until the end of the mission.

The surprising comet
26 September 2016As Rosetta began homing in on Comet 67P/Churyumov–Gerasimenko in the weeks leading up to its arrival in August 2014, it became very clear that this was no ordinary comet. But its striking shape was only just the beginning of the comet's surprises.

An encounter with Klim Churyumov
11 November 2016Two years ago this week, the entire world was getting ready for a historic endeavour in space: the first soft landing of a human-made probe on a comet. The day before landing I had the pleasure to briefly meet Professor Churyumov and even asked him a few questions, taking down notes with the help of his interpreters.
Last NAVCAM archive release
20 October 2016The last batch of NAVCAM images taken by Rosetta during the final month of its incredible mission at Comet 67P/Churyumov-Gerasimenko have been released to the Archive Image Browser. The image set covers the period 2-30 September when the spacecraft was on elliptical orbits that sometimes brought it to within 2 km of the comet's surface.
