Main payloadbuilding assignment Basic components Payload box select

Main payload-building assignment Basic components • Payload box (select materials: must be light (no more than 2 lb total pre-rigging weight), strong, insulating) • Heater circuit (required) • HOBO (monitor internal temp (at least) and external temp (probably), might also plug in one other sensor with voltage cable (like a solar panel)) • On-board data logging with Ballon. Sat Easy flight computer and weather station • Can send analog voltage data to the ground while in flight using Zigbee radio • Camera (still or video) may look up/down/out depending on experimental needs Science/engineering experiments • Characterize external temperature, pressure, relative humidity of atmosphere with weather station • Document internal temperature (for spacecraft “health”) and relative humidity of payload box with HOBO • Use the camera to do some interesting experiment, not just “take pretty pictures” – Some ideas: Layers of the atmosphere (possibly using filtering), curvature of the Earth, spectral content of sunlight using diffraction grating, characterize balloon size with altitude, analysis of balloon burst and/or post-burst chaos, landform identification/mapping, vegetation identification (possibly using filters), trying to take photos of the solar corona, etc. • Do one additional experiment of your own choosing (must get explicit permission; watch size and weight limitations)
