Failure Analysis: Magnetometer Data Average: uT

Failure Analysis: Voltage Average: -.78mV

Only 11.5 minutes of data Magnetic field does not change much as a function of altitude Voltage produced is insignificant because it is hard to distinguish from background noise HOBO data indicates Arduino or a sensor failed due to cold temperatures Conclusions

Do more research on all equipment Perform more thorough testing Appendix: Lessons Learned

Heater: Fixed Solenoid: Fixed Payload should be kept as warm as possible before flight Turn switches on and verify LED blinking Program HOBO for Delay Start Switch Camera on and verify that pictures are being taken Appendix: Ready to Fly Again

Remember ladies and gentlemen, always keep the final goal in mind, even when the going gets tough. There will definitely be times when it seems like you’re not going to make it but in the end it will all work out. Don’t procrastinate, because, no matter what, things are going to go wrong last minute and you’ll be scrambling to fix them. Make sure you do LOTS of research, because knowing about all of your experiments will help immensely. All the papers and presentations may seem redundant but they help you have a better understanding of what you will need to do. In the end, this class will be one that you will never forget and just remember that failures are still okay as long as you guys tried really, really hard. Appendix: Message to Next Semester
