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.

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.

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...

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.

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.

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.
