TBA (Team #5)Launch Readiness Review

Fall 2011 Rev A11-01-11

•Measure the Earth’s magnetic field intensity•Measure the voltage produced •Determine the orientation of pictures

Mission Overview

Purpose of Mission: • Prove or disprove Tesla’s Free Energy

Theory• Discover intensity of Earth’s magnetic field• Test the viability of a magnetometer as an

attitude determination system

Mission Overview

•Low Current Sensor and Magnetometer•Arduino UNO and MicroSD Shield•Camera, Hobo, Heater, Batteries

• Sync Magnetometer readings with camera pictures

• First picture taken on the eighth reading• Picture taken every two readings after

eighth

Experiment Testing-Camera/Magnetometer

Structure Testing

Whip Test

Drop Test Staircase Test

After Drop and Staircase Test

• Heater malfunctioned during cooler test• Need to turn on heater in advance of

cooler test to maintain temperature• Another cooler test to be run today

Cooler Testing

HOBO Testing

Internal Temperature Relative Humidity

HOBO taken out of freezer

HOBO placed in freezer

HOBO placed outside spout of hot kettle

• Low current generated by solenoid during flight• Magnetic field intensity decreases as altitude

increases• Accurately predict orientation of satellite

Expected Results

• Keeping satellite at proper operating temperatures

• Arduino doesn’t run for flight duration

Biggest Worries

Level 0 Requirements# Requirement Origin

0.0Test energy generation capabilities of Earth's magnetic field
