Mission OverviewAnalyze 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

Design OverviewA cube of dimensions 16 x 16 x 10 cm 3 Solar cells attached in series to the top of the

satelliteApproximate output of about 12 voltsSolar 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.

Drop TestProcedure:Dropped/thrown off of high locations to make

sure the structure will hold against the flight impacts

Conclusion:Withstood intense structure testing butwe had to improvethe method of securing the lid.

Whip TestProcedure: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 thatit should not during our flight,though some mass simulators did come detached so we had to secure everything more tightly.

Staircase TestProcedure: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.

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.

The LEDs show that the batteries are in a working condition being charged by the Solar Cells

Flight PredictionThere 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.
