Description
OBJECTIVES:
Investigators at Johnson Space Center (JSC) performed a hardware test on the Bioreactor systems to evaluate possible cell growth in microgravity. Cell growth has been used as an indicator for toxic conditions for years. Cells can be grown in the Bioreactor systems. Combining these conditions identified specific toxic compounds in the Shuttle atmosphere and their biological impact. A Biotechnology goal was to provide sensitive mammalian toxicological testing on short-duration flights that identified potential long-duration hazards.

Development of the Bioreactor systems proposed for use in the Space Station depended on understanding the fluid dynamics of such systems in microgravity. This equipment test permitted the comparison of actual microgravity particle trajectories in the rotating vessel, with calculated trajectories, thus providing data required to improve or modify the systems.
