Science Accommodations in the Biomass Production System 2001-01-2231
The Biomass Production System (BPS) is a double middeck locker payload designed to fly on the Orbiter or Space Station. The BPS contains four plant growth chambers (PGCs) with independent control of temperature, humidity, lighting, CO2, and nutrient solution delivery, allowing for multiple experimental treatments. The BPS provides several features to support on-orbit science activities including the ability to downlink system and science data, video cameras with framegrab capability to collect images for recording plant development, access to plants to perform activities such as pollination or tissue sampling, and gas and fluid sampling ports for sampling of the plant environment. Other capabilities include the ability to conduct CO2 drawdowns, allowing photosynthetic measurements, and the ability to meter plant CO2 and water use. Several technology developments have been evaluated for possible implementation during future upgrades to enhance science capabilities.
