title: Role of the astronaut in operating the Advanced Fluid Physics Module.
abstract: The role of man in space is investigated in the operation of the Advanced Fluid Physics Module (AFPM), a scientific instrument dedicated to fluid physics research in a microgravity environment and flown on the Spacelab D2 mission. The astronaut involvement is addressed by applying the criteria of the THURIS study, conducted by NASA for the optimization of future manned space flights. Outcomes of the THURIS study are first summarized. The AFPM characteristics and interfaces are briefly presented. The five experiments performed on board Spacelab D2 are introduced and the involvement of the astronaut is described. Finally, THURIS criteria are applied to an AFPM experiment scenario. Results show that, of all the activities involved in the AFPM nominal operation, two thirds are related to hardware manipulation and to procedure following, while the last third uses the unique astronaut intellectual capabilities, making his presence in orbit mandatory for successful experiment completion.
