 Team OchoCinco plans to create a satellite capable of flying to an altitude of approximately 30 km in order to prove that it may be possible to power a space mission using only energy collected from solar panels attached to the satellite.  We will be using our camera to take photographic proof that power was indeed supplied.

 3 Solar Cells- Output approx 12V  Rechargeable batteries- Connected to the solar cells  LED lights-Used as a way to prove that the solar cells are powering something, sort of a “mock” experiment  Camera- Used for proving that the experiment was successful  Hobo- Collecting the internal, external, and condensation levels of the BalloonSat  Heater- To make sure that the internal temperature stays above -10 degrees C

 Solar cell count went from 8 to 3  Our camera went from being used to take external pictures to internal pictures  We decided not to use the charger manager  Changed dimensions  Changed locations of equipment

Lights Started off dim and then after about 2 minutes reached the brightness of the second picture. About what we expected but we thought the lights would start completely off. Stayed on the entire flight, but the brightness varied a little. Proved we could conduct an experiment using our solar cells within the range of 2.4V 7:36 AM, 8:19 AM, 9:49 AM, 11:09 AM

Accelerometer Graph Temperature Graph Looks about equal to the temperature readings from the HOBO, and what we expected.

Pressure Graph As we expected as the time and altitude increased so did the pressure.

 Our experiment was about what we expected  We had a successful experiment which also proves that we could have powered another experiment  At least 2.4V output at all times (shown by the batteries being lit throughout the flight)

 During the testing we had problems with the camera -Adjusted the settings of the camera-Fixed  During the battery charging testing we realized that we could not drain the batteries completely. -We just decided to drain them as much as we could and still compare the beginning and ending voltages.  The only way that our experiment would be a complete failure was if the camera didn’t work because then we wouldn’t have any proof that our experiment worked.

 We discovered that it is indeed possible to power an experiment powered only by solar panels.  Our camera took pictures of our LED lights being lit the entire flight meaning that at least 2.4V of power was present the entire flight.  Use for future space teams allowing more experimental freedom -More room -More weight

 Make sure what you are ordering can easily be integrated to everything else  Start early and work often  COMMUNICATION.  We would want some way of measuring the charge transferred from the solar cells to the batteries which we were planning on with a charger manager until it didn’t integrate easily.

 Storage  Remove batteries  Store at room temperature without a large level of humidity  Two drained Li-ion batteries will have to be stored with the satellite if there is a chance of another flight.  Payload Activation  If the payload has been stored in accordance with the above specifications.  Attach the camera wire to the AVR  Insert Li-ion batteries  Flip the two switches on top of the satellite beginning with the “main” switch

 Team OchoCinco shall abide by the following requirements  An additional science experiment is installed inside of the BalloonSat Complete  After flight, the BalloonSat shall be turned in working and ready to fly again. Complete  The plastic tubing provided shall be installed through the center of the satellite so that it can be easily connected to the balloon tether. It will be connected in such a way that it will not pull through the BalloonSat or obstruct the flight string. Complete  With the heater provided and the layout of our design, the BalloonSat’s interior will not go below -10 degrees C - Complete  The entire electronic system, with the exception of the external temperature probe, will remain within the main structure of the BalloonSat. Complete  Our total weight shall not exceed a total of 850 grams. Complete  The Balloonsat design allows for a HOBO H that is 68x48x19 mm and 29 grams. Complete  The Balloonsat design allows for external temperature cable. Complete  The Balloonsat design allows for an Canon A570IS Digital Camera that is 45x75x90mm and 220 grams. Complete  Contact information and a United States flag shall be visibly displayed on the exterior of the satellite. Complete  All parts were ordered using Chris Koelher’s CU mastercard, and thus, all hardware is property of the Colorado Space Grant Consortium and will be returned to the Colorado Space Grant Consortium at the conclusion of the semester. Complete  No one shall get hurt during the design or launch of the BalloonSat. Complete  The satellite shall be in working condition before launch on 11/07/2009. Complete  A final report shall be submitted and a presentation given involving the final design and results Almost Completed

 Start work early  Make sure all of the group is doing their share, because you won’t have enough time to do it without everyone’s participation  Make friends with Tim May and the Space Grant team  Don’t get discouraged
