ESA and NASA Certificates
I was fortunate enough to be attached to ESA's Cluster (and Double Star) and Rosetta teams for quite a few years, helping to publicise their activities and successes on the ESA website and writing various ESA publications (see brochures page). Here are two certificates that I was given in recognition of my "outstanding contribution" to the Cluster / Double Star missions. I also received a Group Achievement certificate from NASA in 2004, in recognition of my "contributions to the success of Cluster's exploration of geospace".
