Team Space Jam Launch Readiness Review Paul Guerrie, Ben Azlein, Megan Scheele, Bridget Chase, Shane Meikle, Taylor King, & Jamie Usherwood November 2, 2010 Fall 2010 Rev C

Mission Overview The main mission of Project Monstar shall be to build a satellite that ascends to an altitude of 30km following the RFP. Project Monstar will test the use of a servo as a means of rotating a camera in the y plane, while the balloonsat naturally rotates in the x plane. The secondary mission of Project Monstar shall be to take pictures 360 degrees, to prove the use of the mechanical system. Project Monstar shall also record attitude of the camera with the use of a digital compass. It will also measure internal humidity, internal and external temperature of the balloonsat. Hypothesis We hypothesize that our mechanical system will operate by fully rotating 360 degrees in the y plane, as the balloonsat ascends to a height of 30 kilometers. We believe that the ability to make a panoramic picture will prove the successful use of our design.

Design Overview

Cold Test In our initial cold test, after an hour and 45 minutes our servo motor stopped rotating. This problem is thought to be caused by the failure of our heater, however we could hear the servo operating throughout the test. However, the HOBO and digital compass both operated properly throughout the test.

Functional Test Our team hung our balloonsat from a tree outside the DLC and continued to spin it while running the servo motor, the camera running video, HOBO, and the digital compass. The test proved that the satellite would function properly while the satellite was spinning. All electrical components proved to work properly as expected.

Structural Tests The staircase, drop, and whip tests were performed outside and inside the ITLL and in the DLC. These tests showed minimal damage to the structure of the satellite. On the prototype, one of the arms holding the camera was slightly bent and dented with minimal cracks on the top of the satellite.

Predicted Results Panoramic pictures – full view from satellite to accurately show flight Used in future experiments – record direction sensitive data in 360 degrees

Biggest Worries Having the servo survive the harsh temperature of near space. Condensation on the camera lens. Freezing of the camera in near space. Having the extended parts of foam core structure (that hold the camera) survive impact.
