In the foreground (from the left), are astronauts Scott E. Parazynski and Pedro Duque, both mission specialists, and U.S. Sen. John H. Glenn Jr., payload specialist. Duque, representing the European Space Agency (ESA), has his right hand on the centrifuge. Sen. Glenn holds a vial of blood that would be placed inside the centrifuge.
