Plant-module for autonomous space support (P-MASS).
A wide variety of technical and science questions arise when attempting to envision the long-term support of plants, algae and bacteria in space.  Currently, spaceflight data remain elusive since there are no U.S. carriers for investigating either the germane technical or scientific issues.  The first flight of the Commercial Experiment Transporter (COMET) will provide a nominal 30 day orbital opportunity to evaluate such issues.  The P-MASS is a small payload that is designed to meet the mass (40 lbs.), volume (1.5  cu.ft.), and power (120 W) constraints of one of several COMET payloads while enabling flight evaluations of plants, algae and bacteria.  Various P-MASS subsystems have been subjected to extensive ground tests as well as KCl35 tests.  Various biological sub-systems have been similarly evaluated.  Through a variety of sensors coupled with color video, the P-MASS performance and the supported biological systems will be compared for terrestrial controls versus spaceflight materials. This small, low cost payload should return valuable information regarding the requirements for hardware and biological  systems needed to  move toward bioregenerative life support systems in space.  In addition, it should be possible to accurately identify  major unresolved difficulties that may arise in the long-term, spaceflight support of various biological systems.  Finally, this generic spaceflight capability should enable a variety of plant research programs focused on the use of microgravity to modulate and exploit plant products for commercial applications ranging from new agricultural products to pharmacological feedstocks and new controlled agricultural strategies.
