The selection, definition, and development phases of a Life Sciences flight research experiment has been consistent throughout the past decade. The im plementation process, however, has changed significantly within the past tw o years. This change is driven primarily by the shift from highly integrate d, dedicated research missions on platforms with well defined processes to self contained experiments with stand alone operations on platforms which a re being concurrently designed. For experiments manifested on the Internati onal Space Station (ISS) and I or on short duration missions, the more modu lar, streamlined, and independent the individual experiment is, the more li kely it is to be successfully implemented before the ISS assembly is comple ted. During the assembly phase of the ISS, science operations are lower in priority than the construction of the station. After the station has been c ompleted, it is expected that more resources will be available to perform r esearch. The complexity of implementing investigations increases with the l ogistics needed to perform the experiment. Examples of logistics issues inc lude: hardware unique to the experiment; large up and down mass and volume needs; access to crew and hardware during the ascent or descent phases; mai ntenance of hardware and supplies with a limited shelf life; baseline data collection schedules with lengthy sessions or sessions close to the launch or landing; onboard stowage availability, particularly cold stowage; and ex tensive training where highly proficient skills must be maintained. As the ISS processes become better defined, experiment implementation will meet ne w challenges due to distributed management, on-orbit resource sharing and a djustments to crew availability pre- and postincrement.
