European Modular Cultivation System (EMCS) European Space Agency:
FACILITY SUMMARY: EMCS provides a facility where small organisms (plants, microbes, insects, amphibians) can grow in variable gravity conditions (0.001G to 2.0G) using a rotating centrifuge. It was designed for multi-generation experiments and studies on gravity effects on early development and growth in a variety of organisms.
EMCS will facilitate long-term plant growth studies, including multi-generation studies (seed to seed), early development events in plants, gravity influence on early development and growth (g-level threshold research) and how plants perceive and respond to gravity as they grow.
FACILITY OPERATION: SEMCS consists of a gas tight incubator containing two centrifuges with space for 4 Experiment Containers on each rotor; the life support and water supply system, and the illumination and the observation system are located on the rotors.
Once on ISS, the turning of the rotors can be used to apply a gravity effect between the normal microgravity and 1G experienced on Earth.
Minus Eighty Degrees Laboratory Freezer (MELFI):
FACILITY SUMMARY: This multi-purpose freezer significantly enhances the research capabilities of the US Laboratory on ISS.
Supports a wide range of life science experiments by preserving biological samples (such as blood, saliva, urine, microbial or plant samples) collected onboard ISS for later return and analysis back on Earth.
Samples from the ISS Medical Project will be stored in MELFI and contribute to multiple studies of the effect of space flight on human health in support of the Vision for Space Exploration.
FACILITY OPERATIONS: The freezer is based on the Brayton Thermodynamic Cycle which uses nitrogen as a working fluid. It includes four nitrogen-cooled dewars which can be controlled independently to keep samples at any of three different temperatures: -80, -26 and +4Â°C (-112, -15 and 39Â°F).
After Leonardo is unloaded, used equipment and trash will be transferred from ISS for return to Earth. The logistics module will be detached from the ISS and positioned back into Shuttle’s cargo bay for return.
Other key events for Flight Day Four include: Preparations for for EVA 1.
Perform Orbiter Boom Sensor System focused inspection survey.
Transfer logistics and Shuttle middeck items.
