2. Mission Overview ESAM’s mission is to send a balloon satellite to an altitude of 30 kilometers in order to collect wattage data of the electromagnetic spectrum. ESAM’s mission is to send a balloon satellite to an altitude of 30 kilometers in order to collect wattage data of the electromagnetic spectrum. An infrared sensor and an ultraviolet sensor will be used in order to determine the flux of infrared and ultraviolet light throughout the troposphere and lower stratosphere. An infrared sensor and an ultraviolet sensor will be used in order to determine the flux of infrared and ultraviolet light throughout the troposphere and lower stratosphere. The sensors will collect data in the ranges of 210-380nm in the ultraviolet and 750-1400 in the infrared. The sensors will collect data in the ranges of 210-380nm in the ultraviolet and 750-1400 in the infrared. We expect to see an increase in both infrared and Ultraviolet intensity as a function of altitude. We expect to see an increase in both infrared and Ultraviolet intensity as a function of altitude.

21. Failure Analysis AVR camera activation failed AVR camera activation failed When plugged in, the camera immediately turned on. When plugged in, the camera immediately turned on. Several attempts to unplug and re-plug. Several attempts to unplug and re-plug. Camera now fixed, polarity of wires reversed. Camera now fixed, polarity of wires reversed. Not actually a big deal, didn’t effect pictures… Not actually a big deal, didn’t effect pictures… ready for re-fly! ready for re-fly!

22. Conclusions UV light increases with altitude UV light increases with altitude Ground flux: ~0 W/m^2 Ground flux: ~0 W/m^2 Max flux: ~1.4 W/m^2 Max flux: ~1.4 W/m^2 IR light more complicated IR light more complicated Possible sensor malfunction. Possible sensor malfunction.

24. Lessons Learned What we would have done differently. Time management (baseline testing, opp amp) Time management (baseline testing, opp amp) Better understanding of opp amp hardware Better understanding of opp amp hardware Better understanding of parsing data. Better understanding of parsing data. Use two more IR sensors for more accurate data Use two more IR sensors for more accurate data If we could change it… Better time management Better time management Debugging AVR sooner, rather than later Debugging AVR sooner, rather than later

30. Some people seemed to dislike this class but we really liked it. We had a good group that worked well together and has diverse talents/knowledge coming into the project. We were fortunate enough to have people with backgrounds in computing, astronomy, business, and leadership. Be prepared to work a lot but…it’s really not that bad, just manage your time well. Expect to work more than once a week; we met three times a week and still ran out of time. Even if you think you’re ahead of schedule, don’t take a week off, keep working. Also learn as much about your hardware as much as you can so that when “the sh*t hits the fan” you know how to fix it. Team leader, don’t be afraid to tell your team what to do. Assign them different sections of the DD and make sure they get done when you want them done. Overall this class was a valuable learning experience in more ways than just launching a satellite. And it was fun! Message to Next Semester
