  • Safety Procedures


Mission overview

Mission Overview

  • Form a scientific experiment that will take place 5,280 ft above ground

  • Design, build, and test a rocket capable of performing the scientific experiment at 5,280 ft

  • Design, build, and test a scaled model of the full size rocket


Changes made since pdr

Scientific experiment execution

Scientific Experiment Execution

  • Design a rocket that can house a scientific payload

  • Design and integrate a scientific payload that can measure visible light intensity levels during flight

  • Initial data will be taken from the ground during preflight to provide experimental control


Scientific payload

Scientific Payload

  • Each visible light sensor is constructed using a board and mounting hardware

  • The circuit board will be mounted on the center rails with two-conductor coaxial wires connecting the photodiode to the PCB


Scientific payload bay

Scientific Payload Bay


Scientific payload1

Scientific Payload

  • Two Solar Light model PMA 1140 visible light sensors

  • Two Omega OM SC data loggers

  • Data will be collected pre-flight, during flight and retrieved post flight

  • Sample rate will be .88 seconds for two hours
