Mission Overview

Teamo Supremo’s objective was to discover at what altitude stars become visible between 65,000 and 100,000 feet.

This was to be accomplished through the use of a CCD video camera outfitted with an infrared filter and an HP Photosmart digital camera.

RFP Compliance

We were over the weight restriction of 800g at 933g

We flew the HP camera but unfortunately received no data

We followed our mission statement

Design was correct, but there were technical errors

We stayed under budget (given: $200…Used:$93.07)

Differences from Proposal to Final

Brainstem or basic stamp was not used recorder was used instead

Infrared lens was further from surface of camera lens than first anticipated

No fish-eye lens No solar panels 45* angle added to make design into a pentagonal

shape Fiberglass reinforcement of structure

HP data

The HP camera did not collect any data from flight because it was turned on too early.

After the camera was turned on, the flash was turned off. However, the timing circuit was turned on later to reduce the amount of images before flight to prevent the memory from being filled.

In the time between turning on the camera and timing circuit the camera shut off on its own so no pictures were actually taken.

Solution: Turn on camera and turn off flash. Immediately turn on timing circuit.

CCD Imaging Data

We have no data from flight. We do have data of the launch day preparations. After our final test we adjusted the image quality which

drained the batteries much faster than during the test. As a result the batteries died before launch.

Solution: Instead of three 12 volt batteries, a system of three 9 volt batteries with a 12 volt regulator will be used. This will extend life of the power source and increase the amount of data collected.

CCD Testing

This test proves that we could see stars. If our batteries hadn’t failed, our CCD would have seen stars…

Conclusions/Lessons Learned

We did not achieve our mission objective. Since we have no CCD camera data from the flight, we do not know at what altitude stars become visible, or even if they are visible at all from a balloon satellite between 65,000 and 100,000 feet. In addition our HP camera also failed so we do not have still pictures either.

Lessons Learned

Set the HOBO to record data for a longer length of time than the estimated flight time. Doing this ensured that we got data from the entire flight.

The HP camera turns off after five minutes of inactivity. The three 12V batteries only provided about 20 minutes

of power to the CCD camera. A power pack using three 9V batteries would have provided about two and a half hours of data instead.

Ready to Fly Again Clear to Go!

All batteries have been replaced with fresh ones 9Volt power pack replaced 12Volt power pack for CCD camera Store in a room no cooler than 50 degrees F and no warmer than 90 degrees F

To activate…turn on switches in following order: 1) Turn CCD switch to “ON” 2) Turn Recorder switch (on side of device) to “ON” 3) Press the “record” button until the red light appears on the recorder 4) Turn the switch labeled “timer” to “ON” 5) Turn the camera switch to “ON” 6) If a flash is unnecessary turn the flash off on the camera body 7) Turn the switch labeled Heater to “ON” 8) Once all switches are in correct position, tape down switches and close lids.

Tape outside of lids with aluminum tape that has been colored or painted black to eliminate light interference.

Message to Next Year

Have fun!

Be creative!!!

Don’t over think everything but make sure you think through everything!!

Do what you know, learn what you don’t
