Objectives
In order to conduct Risk Mitigation for the BioTechnology Facility on the ISS, the BTS was designed and flown on the Mir Space Station. The purpose of the BTS was multi-fold and included: (1) demonstration of technology and systems to support biotechnology investigations, (2) validation of BTF concepts and systems through long-duration operations, (3) verification of BTF operational and training procedures, (4) verification of the launch and transfer of operating experiments between orbiting spacecraft, and (5) Fundamental Science investigations.
Shuttle-Mir Missions Approach
Results
The BTS Operations experiment results was two-fold in the sense that it evaluated the operations of hardware and it was used to support on-board investigations. The major accomplishments included technology and systems demonstration in these areas:
· Data Acquisition and Control System (ECC, Flashcards, recovery software)
Conclusions are pending completion of analysis in FY99.

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. NASA's biotechnology facility provides a tool to conduct biotechnology experiments while in the microgravity environment. Advances made in hardware development have application for designing better instrumentation on the ground.
