2. Mission Overview Analyze the intensity of Sunlight at both ground level and 30 km by measuring the input/output efficiency of our solar cells. Measure the time interval required to charge the Li-ion batteries with solar cells Apply collected data to other space experiments -Less weight -More room for experimentation 6/10/2015 Team Ochocinco

3. Design Overview A cube of dimensions 16 x 16 x 10 cm 3 Solar cells attached in series to the top of the satellite Approximate output of about 12 volts Solar panels connect to a controller board that will control the input voltage going into the 2 rechargable batteries and then light two LED lights. The camera will take pictures of the LED lights every 20 seconds. 6/10/2015Team Ochocinco

6. Drop Test Procedure: Dropped/thrown off of high locations to make sure the structure will hold against the flight impacts Conclusion: Withstood intense structure testing but we had to improve the method of securing the lid. 6/10/2015Team Ochocinco

7. Whip Test Procedure: Thread a rope through the flight tube and swing it around to simulate the effects of our payload being attached to the balloon Conclusions: Our box did not become detached so it proved that it should not during our flight, though some mass simulators did come detached so we had to secure everything more tightly. 6/10/2015Team Ochocinco

8. Staircase Test Procedure: We had one teammate kick our satellite down two flights of stairs to also simulate the stress of impacts on even surfaces. Conclusion: Our satellite passed the stair test with no further problems. 6/10/2015Team Ochocinco

9. Cold Test 6/10/2015Team Ochocinco BalloonSat with all equipment powered in a cooler with roughly 3.5 lbs worth of Dry Ice Procedure: We will expose our BalloonSat to extremely low temperatures to simulate the conditions in space and be able to keep our internal temperature above -10 degrees C. We placed our payload in a cooler full of dry ice for 2-3 hours. Conclusion: The components were able to work after we fixed the arming problem.

10. Full Systems Test 6/10/2015Team Ochocinco The LEDs show that the batteries are in a working condition being charged by the Solar Cells

11. Flight Prediction There will be an increased voltage charge in the Li- ion batteries at higher altitudes. The camera will collect pictures from about 10 minutes before launch to recovery time. This will give us a timeline as to when the LED lights were light or not. This experiment will have a lot of applications to other space experiments. -Space constraints -Power constraints 6/10/2015Team Ochocinco
