Our mission is to supply accurate data about cosmic radiation by building a safe and functioning rocket that can provide ample time for data collection.
•Reach an altitude of one mile.
•Payload records data on ionizing radiation.
•Both parachutes deploy at predetermined altitudes.
•Land within one square mile.
•Rocket retrievable with payload intact.
•Shed light on radiation variation with altitude.

Outside of Lower Body Tube
After consideration of the effects due to terrestrial radiation, we expect the altitude of minimum radiation to be approximately 700 ft.
Of particular interest is the non-monotonic region in the graph of the data from our previous experiment. We expect terrestrial radiation may be scattered or reflected by the atmosphere
(1) Radiation will be measured using scintillator probes which are much more sensitive to gamma radiation than Geiger Mueller tubes and can give as a more accurate picture of how radiation is distributed with altitude.
(2) Radiation levels are suggested to be associated with changes in atmospheric conditions (such as cloud formation and global warming; chlorine production and ozone depletion)
(3) Radiation levels are linked to the breakdown of DNA in organic tissue and so merit further study.
•Payload – Scintillator probe:
(a) consistency of data collection,
(b) background counts,
(c) isolation of ray sources.
•GPS – Locality tracking.
•Recovery – Ejection charges and chute deployment. Safety and RF Signals.
•Propulsion – (a) Inspection of parts
(b) assembly supervision.
•Vehicle – Scale model launch.
•Camera – Video testing.
Prior to each project phase:
Review system risks and mitigations.
Review Safety Codes.
Pass test on Safety Procedures.
Sign Safety Statement.
Current major purchases
• LOC Precision Magnum 3-E kit with plastic fins $291
• Payload materials (scintillator, photomultiplier tube, casing, and accessories) $400
• Recovery System and motor $500
• Remaining payload components $500
• Continued exploration of fund raising strategies.
• We helped boy scouts earn their space exploration merit badges by providing information on space exploration and by helping the boys build and successfully launch the rockets on our baseball field.
