Team S.H.I.E.L.D.Final Presentation

To See the Stars

Mission Overview To obtain Video Footage of the Flight to show that it is

Possible to See stars at High Altitudes even during the Daytime.

To Ascertain what Altitude is Required for such Observations. 11km is the Expected Altitude needed, based on Research.

The Legendary Dodecahedron

Design Overview Main Hardware (Not the Required Stuff):

CCD Camera Pressure Hobo

From Proposal to Final Product: Took out a Heater Removed the Aluminum Support Beefed up the Size of the Dodecahedron No Plexiglas Panel (Just small Plexiglas Windows) Added the Pressure Hobo

Show me the Data!

Results and Analysis We expected to Get some Video of the Stars and

be Able to Find at what Altitude they Starting becoming Visible

Though there was some Issues with the Temperature, Almost everything worked during the Whole flight.

Based on the Data we can See that the Flight went just as Predicted in terms of External Temperature and Altitude.

Other than some Very cold Hands and Equipment, the Flight went Very well.

Cap’n She’s Breaking Up!

Failure Analysis Our Cannon Camera Failed, and we Failed to maintain at least 0

degrees Celsius. The Data shows the Temperature inside the Dodecahedron, and the

Camera has no Pictures on it. We believe the Camera failed due to the Programming.

We tested the Camera multiple times, only a couple of Images were saved though the Camera appeared to be taking many Photos.

While we are mostly Certain the Cold did not Affect the Camera, we can’t be 100% sure. But the tests indicate that there are Issues even in a Warm environment.

We have no Idea how to Fix it other than Reload the Programming, but since the Camera seemed to be working before the Launch we’re not even sure we can Be sure it will work every time.

Aftermath

Conclusions Unfortunately due to very Shaky video we Were

unable to get and Images of Stars. Since we know most of our Equipment worked, the

best Addition we could make to get the Video we want would be a way to Stabilize the BalloonSat.

What did we Learn?

Lessons learned If we could do it Again:

We would Substitute the Cannon Camera with another CCD

Try to get a better Quality CCD Camera Attempt to Stabilize the BalloonSat or the Camera Try to add another Heater or more Insulation

Make Jared Ride with Someone Else to the Launch…not Drive Himself

Done that… maybe Again?

Ready to fly again Store in a Dry place, where thee is no Chance of the

BallonSat being Damaged Leaving two Panels open until right before the

Launch (so we could Turn on the DvR) worked well for us.

Make sure you have New Batteries in Everything.

Appendix

Our Message: Expect to spend 10 hours a Week with your Group.

Start working as Soon as Possible, don’t Procrastinate. Try to think of Possible Failure Points, and Fix them ASAP.

Do your Best to Avoid Stress, take breaks as you need them, but Keep on Track (or you’ll just get More Stressed).
