  2. Mission Overview • Objective • The object of this mission is to test the amount of light intensity gathered by solar cells at different altitudes and take a panoramic image at near space. • The balloon satellite will take the instruments to a near space altitude where at intervals they will measure the amount of light intensity collected. • Two cameras angled so they slightly overlap will be used to take pictures of the horizon. These will depict a much larger space than could be achieved with one camera.

  3. Requirements Flow Down

  4. Design • Parts Ordered • 8 Solar Cells • Voltage input cable • How long will it take to get the parts? • Have By 25 October 2007

  5. Design

  6. Design • Block Diagram

  7. Management • Schedule

  8. Cost

  9. Mass Budget

  10. Testing (Systems) • Systems Test • Each internal component will be tested for a length of time similar to the flight time • We will be looking to see if anything was wired incorrectly in a component • Causing battery to drain faster than it should • Incorrect data being collected • Once subsystems completed, entire system as a whole tested in similar way. • Heater Test • Place the sat in a cooler filled with dry ice for 2+ hours • If the temperature inside the balloon sat drops too low for its components to work, change the insulation design.

  11. Testing (Structural) • Drop Test • Construct prototype • Dropping model from approximately twenty feet • Should give us idea of how well the balloon sat will hold up on impact • If it fails, it will be strengthened with new shape and/or materials. • Whip Test • Determine whether the system can hold its structure during the descent • Model tied to a short string and swung as fast as possible • Simulate the forces that will act on it during descent. • If it fails this test, we will reattach the internal systems of the sat more securely

  12. Expected Results • System/Heat Test • No problems expected with heater/timing circuits • Less than 2.5 Volts to HOBO Logger • If more -> Zener Diode • Drop/Whip Test • Don’t expect current structure design to be perfect with such a unique design. • Plenty of extra mass allotted for structural reinforcement.
