30Apr2012: Premiere on the fourth test day: For the first time, a science experiment is handed over during an ongoing activity to research teams from overseas. Via audio and video telemetry and a continuous stream of suit sensor network data, the reseachers at the NASA Jet Propulsion Laboratory in PAssadena/California direct the suit tester to the desired sample location. In this case, biologist Lara Vimercati assists the suit testers in taken the very samples which will than be analyized in the JPL laboratories. Photo: OEWF (Katja Zanella-Kux)
