INTERNATIONAL SPACE STATION Utilization Statistics Expeditions 0 – 50 December 1998 – April 2017
This is a product of the ISS Program Science Forum comprised of representatives from the ISS Partner Agencies: Canadian Space Agency (CSA), European Space Agency (ESA), Japan Aerospace Exploration Agency (JAXA), National Aeronautics and Space Administration (NASA) and the Federal Russian Space Agency (Roscosmos) and the ISS Participant Agency: Italian Space Agency (ASI).
Additional Resources: ISS Research and Technology on the Web: http://www.nasa.gov/iss-science/ Follow us on Twitter: @ISS_Research MCB Approved February 2018 NUMBER OF INVESTIGATIONS PERFORMED ON THE INTERNATIONAL SPACE STATION The information below provides an overview of ISS utilization up to the end of April 2017. An Expedition pair reflects the 6-month period used by the ISS Program for planning and execution of its activities. The utilization reflects activities of all of the ISS International Partners: CSA, ESA, JAXA, NASA, and Roscosmos. An investigation is defined as a set of activities and measurements (observations) designed to test a scientific hypothesis, related set of hypotheses, or set of technology validation objectives. Investigators include the principal investigator(s) and co-investigator(s) that are working to achieve the objective of the investigation.
