Team Solkraft Conceptual Design Review Fall 2010 Rev A 08-23-10 Team Solkraft Conceptual Design Review Thomas Buck, Kyle Garner, Alexandra Jung, Quinn Mcgehan, Mark Sakaguchi, and Scott Taylor 9/16/2010

Mission Overview To test the effectiveness of solar panels under near-space conditions of approximately 30 km. We expect the functionality of solar panels to vary under different conditions of temperature and light intensity. We want to see what is the most efficient way to use a solar cell.
