She worked with Andrew Walsh on Cluster Observations of Flow Braking in the Magnetotail and produced an excellent report at the end of her placement. We are pleased to welcome Keith Grimstone and Adrian White (Workshop), Simon Jackson (Systems Engineering), Dr Stefano Pasetto (Astrophysics) as well as seven new PhD students. They are Gemma Cauchi (Climate Extremes), Matt Hills (Cryogenics), Jason Hunt (Astrophysics), Jamie Jasinski (Planetary Science), Kirthika Mohan Narasimhan (Plasma Physics), Ailsa Prise (Solar Physics) Tom Pollard (with Louise Harra and Kevin Fong at UCLH). Summer students Christopher Suberlak, Grace Cox and Hugh Osborn worked in the Planetary Science group. Mission Status and Developments The 2011 MSSL Croquet Tournament was fiercely fought and much enjoyed. Congratulations to Climates Extremes (Mark Saunders, Adam Lea and Alan Muir) for winning the tournament. They beat the Technology Management Group (Michael Emes, Ady James, Phil WIlliams and Matt Wyndham) 14-4 in just under an hour. Cassini - Cassini is in its extended („solstice‟) mission. CAPS analysis was presented in many papers and at meetings (see lists). Cluster – MSSL celebrated 10 years of the Cluster mission on 22 June. The event was attended by Dr. Matt Taylor (Cluster project scientist, ESA) who -1- gave a presentation. Arridge, C.S., N. Achilleos, P. Guio, Electric field variability and classifications of Titan‚Äôs magnetoplasma environment, AnGeo Communicates, 29, 1253-1258, doi:10.5194/angeo-29-1253-2011, published 19 July 2011. http://www.anngeophys.net/29/1253/2011/angeo-29-12532011.html. This paper shows that the electric field imposed on Saturn's moon Titan from Saturn's magnetosphere can be highly variable. We demonstrate that this variability is not captured by classifications of Titan's plasma environment.

The mission „yellow book‟ will be written by November, with downselect in February 2012. ESR-2 – retired on 6 July after a fantastic 16 years of operational service. Having far exceeded its original design lifespan of 3 years, the ERS-2 has provided a valuable link allowing cross-calibration of missions from ERS-1 through to the CryoSat era. See: http://www.esa.int/esaCP/SEM3IP6TLPG_index_0. html ExoMars – PanCam activity continuing, including work on DC-DC converter.
