On Thursday, 15 October 2009, at the same time as the 300th anniversary celebrations of Berlin's Charité university hospital began, the ThermoLab experiment was launched on the International Space Station (ISS). Scientists from Charité want to use the experiment to study changes in the heat balance and the circulation of people who are in zero gravity conditions. A new sensor that was jointly developed on behalf of the German Aerospace Centre (Deutsches Zentrum für Luft- und Raumfahrt; DLR) by Charité and Draegerwerk Lübeck is being used.
