Life Science Telemetry Module (STL-B)

STL_B_Photo.jpg (32722 bytes) The STL-B is a video microscope module that provides a flexible platform for a variety of life sciences experiments in microgravity. The system allows real time downlinks of the video microscopy image. Microscopy is accomplished via xyz translation and astronaut focus or automatic search / scanning protocol. The images are downloaded to dedicated experiment monitoring systems on the ground and/or through NASA Select transmission. Because early ISS experimentation is severely constrained by availability of astronaut support, fully automated experiment modules with telemetry capability will be instrumental in fulfilling experiment requirements. The STL-B is ideally suited for long duration experiments aboard the ISS.
