Rosetta reveals mysterious Lutetia
On 10 July 2010, ESA's Rosetta spacecraft flew past asteroid Lutetia, one of the largest objects orbiting within the main asteroid belt between Mars and Jupiter. Rosetta's encounter revealed an intriguing object which has survived since the birth of the planets.

Hubble and Rosetta unmask nature of recent asteroid wreck
High-resolution images from the Hubble Space Telescope and a rare view obtained, from a unique perspective, by the Rosetta spacecraft provide a comprehensive picture of P/2010 A2, a puzzling body in the asteroid main belt.

Rosetta operations strategy modified following a RCS test
During a test performed on Rosetta's Reaction Control System (RCS) on 9 September 2010, a leak has been identified in this sub-system in an area which cannot be isolated. Despite the unwelcome news, an operation strategy has already been defined that conserves the mission objectives without re-pressurisation of the RCS system. Rosetta will...

Rosetta's OSIRIS cameras reveal the nature of asteroid Steins
Close-up images of asteroid (2867) Steins, obtained with the OSIRIS cameras on Rosetta, have provided extensive new measurements of the physical properties of this main-belt asteroid. Steins is revealed to be a loosely-bound 'rubble pile' whose diamond shape has been honed by the YORP effect. This is the first time this effect has been seen in a main-belt asteroid. The results are reported by H. Uwe Keller and colleagues in the 8 January issue of Science magazine.

Rosetta's third Earth swingby
On 13 November 2009 Rosetta will swing by Earth passing within 2500 km of the surface. This is the last in a series of gravity assists to provide the spacecraft with the required orbital boost to set course for comet 67P/Churyumov-Gerasimenko.

Rosetta's scientific instruments ready for close encounter with Steins
As the Rosetta spacecraft closes in on asteroid Steins the science instruments are prepared for this extraordinary opportunity to study a rare, E-type asteroid. Final orbit trajectory corrections have been performed and the spacecraft is now on track for a closest approach at 20:58 CEST at a distance of 800±2 km.

Rosetta fine-tunes its approach to asteroid Steins
On 4 August Rosetta starts to use its cameras to visually track asteroid Steins. These observations will be used to refine the trajectory of the spacecraft relative to Steins and to adjust it, if necessary, to achieve the desired fly-by conditions.

Rosetta lander named Philae
With just 21 days to the launch of the European Space Agency's Rosetta comet mission, the spacecraft's lander has been named "Philae". Rosetta embarks on a 10-year journey to Comet 67P/Churyumov-Gerasimenko from Kourou, French Guiana, on 26 February. Philae is the island in the river Nile on which an obelisk was found that had a bilingual inscription including the names of Cleopatra and Ptolemy in Egyptian hieroglyphs. This provided the French historian Jean-François Champollion with the final clues that enabled him to decipher the hieroglyphs of the Rosetta Stone and unlock the secrets of the civilisation of ancient Egypt.
