Undergraduate Student Instrumentation Project: A New Approach on Sampling Microorganisms from the Lower Stratosphere


Summary. Obtain cross-sectional data of microorganisms collected in the lower stratosphere using an efficiently designed, lightweight, balloon-borne suctioning mechanism. Data useful for further studies in field of microbiology and atmospheric science. Payload will be flown using latex weather balloon. New Design & Approach. New Payload Design for Sampling Purpose. Large sampling volume. Reduced reliance on electronic movement i.e. pump. Materials rated for extreme environment. Improved Sterilization Measures - Polyphasic approach. Risk mitigation. Multiple environmental readings and tests for redundancy. Next day recovery over Fairbanks’ Active Military Zone. Payload damaged upon landing. Possible impact against snags. Intake mechanism works properly based on stored data.
