h2. Design Parameters (How)





    35
    
    
    





    36
    
    
    
1. Balooon big enough to float it up for the whole time.  Durable enough to not break.





    37
    
    
    
2. Lighter than air He2 or H2





    38
    
    
    
3. Use corrosion resistant materials.  Plastics with a glazing point below the ambient temperature.





    39
    
    
    
4. GPS system for tracking.





    40
    
    
    
5. Vibrant colors and reflectors.  Blinking or flashing lights.





    41
    
    
    
6. Record video with a camera and a memory stick.  Rugged camera.





    42
    
    
    
7. ,8., 13 Only the databox come down when finished. Parachute deploy when it comes down.  POM plastic sphere case around it.  Enough air to float.





    43
    
    
    
9. Flatpanel display. Store on storage medium (flash, magnetic, wireless)





    44
    
    
    
10. Volume and weight.  Way to lift it into the van.  Maximum dimension must be smaller than ??





    45
    
    
    
11. Tools (not needed or needed). If needed have it including if we have to replace it.  If disassembly after used, then same applies for landing site.  Stick to general hand tools (hammer, screwdriver)





    46
    
    
    
12. We can run it on the ground at the takeoff site.  Well developed inspection protocol -- prelaunch checklist.  Need a way to get some data off it while on the launch site.  Go to launch site before and do some tests.





    47
    
    
    
14. Small as possible with address on it. Prize for returning.  Limit the distance and/or time so we can pick it up.  Make it be the procedure to go pick it up.  Really good tracking and lights.





    48
    
    
    
15 Connectors between the high-value components and the system





    49
    
    
    
16. Software and interfaces that can download the video at RU





    50
    
    
    
17. Good disclaimer on all things and use all the time we have
