Objectives
The objectives of this experiment were to verify and validate the Data Acquisition and Control System (DACS) for the BioTechnology Facility on ISS. DACS is hardware, firmware and software designed to monitor, operate, and control experiment specific payloads and Facility systems, and to capture and archive experiment data and hardware performance data.

Biological processes can be altered as a result of microgravity. The unique qualities of the microgravity environment could lead to new discoveries in biotechnology which could ultimately result in improvements in medicine, agriculture, and pharmaceuticals. Advances made in hardware development have application for designing better instrumentation on the ground.
