French-speaking UMSFers may be interested in this book by OMEGA's PI Jean-Pierre Bibring
http://www.amazon.fr/Mars-Plan%C3%A8te-ble...g/dp/2738123287
I have bought it yesterday, and just as I expected there are some good informations on Bibring's participation to Fobos, Mars 96, Rosetta and Mars Express.
There is a particularly enjoyable chapter on the birth of Mars Express including some sharp criticism of ESA's PR policy, that privileged useless stunts as flying Ferrari's "racing red" on the probe rather than correctly informing the European taxpayer on what his money was going to pay.
