Yesterday, Crew 40, the Mona Lisa Project, got underway at the Mars Desert Research Station (MDRS) near Hanksville, UT. The Mona Lisa Project is the second half of a study to observe the effects of having an all-female crew in a Mars analogue environment. The first half of the study was the just completed Leonardo Project that had an all-male crew establish a baseline. The idea of sending an all-female crew of six to one of these analogue habitats was born in August 2004 at the Summer Session of the International Space University (ISU). The main research topic of this project is to assess group dynamics in an international all-female/all-male crew in a Mars simulation.
