What are emulsions, and why is it worth our time to investigate how they behave in microgravity conditions on board the International Space Station? Dr Libero Liggieri of the National Research Council of Italy - Institute of Condensed Matter Chemistry and Technologies for Energy (CNR- ICMATE) explains what the PASTA experiment for the study of emulsions is all about. Video production by the Royal Belgian Institute for Space Aeronomy (BIRA-IASB): https://www.aeronomie.be/ -- Acknowledgments -- The PASTA project is funded by the European Space Agency (ESA). The Science Team is led by the Consiglio Nazionale Delle Ricerche - Institute of Condensed Matter Chemistry and Technologies for Energy (CNR-ICMATE), with support teams from the University of Parma and other universities in France, Germany, Greece, USA, Russia, Japan and several commercial entities. The Belgian User Support and Operations Centre (B.USOC), hosted at the Royal Belgian Institute for Space Aeronomy (BIRA-IASB) and supported by Space Applications Services, is responsible for the implementation of select European payloads on board the ISS on behalf of ESA. It acts as the link between scientists and the ISS environment and is responsible for preparing and operating those experiments as well as distributing the raw science data from the experiment to the research teams. The SMD and sample cell hardware was developed and built by Airbus Friedrichshafen in Germany. Thales Alenia Space Italy in Turin was prime contractor for the Fluid Science Laboratory.
