E-USOC (Spanish User Support and Operations Centre)is a centre of Polytechnic University of Madrid (UPM) specialized in Research and Development (R&D) activities in the fields of space science and technology. On behalf of ESA (European Space Agency), the centre offers the necessary assistance for the preparation, execution and post-flight analysis of space experiments to the Spanish scientific community. E-USOC is the point of contact for the Spanish user teams developing experiments which require microgravity environment, such as the International Space Station, Space Shuttle missions, Parabolic Flights and so on. It is also the point of contact for European Users carrying out space experiments involving the payloads which E-USOC is responsible for (e.g., experiments concerning the Fluid Science Laboratory (FSL) onboard the International Space Station (ISS).
