Diego Urbina was a member of the the 520-day isolation crew of the Mars500 study. Diego finished post-mission medical and psychological data collection that followed crew recovery for six months after the Mars500 mission. At the same time, he worked on the final report and took part in other post-mission activities. European crewmembers were based at ESA's technical centre ESTEC, Netherlands until the Mars500 mission ended for Diego in May 2012. (Source: ESA)
