Pandora’s Box Project Epimetheus Proposal  Charles Bogenberger- team manager  Michael Curl- electrician and systems integration  Nicole Demandante- O3 sensor  David – camera and structure  Lisa Rowan- Budget, schedule, and organization  Juhyun Lee- graphics and videography  Aleks Jarosz- accelerometer and structure

Structural Redesign  Design  Changed from cube to rectangular  Shape redesigned around camera  Cut out for mirrors  Better imaging of earth and balloon  Protects mirrors  Better positioning of camera  Allows for more imaging options  Improved impact absorption and structural strength

Parts and Components Status  Have all major components  Having to spend more on miscellaneous parts  O 3 Sensor  Three out of four chemicals here fourth one on its way  Chemicals took longer to get.  This experiment will be practically impossible to test.  Force sensor  Accelerometer not feasible  Will probably use home made device

Stair Pitch Test  No critical damage done  Performed several tests:  Pitched downward from 1 story  Pitched up to a height of 3 stories and freefall  New Design showed improved impact absorption  Major damage was to corners  Overall structurally sound

Cold Test  Attempted Cold Test on Sunday 2/11/03  Status: INCOMPLETE  HOBO failed  Timing Circuit failed  All other components were functioning  Cold test will be re-done ASAP depending on diagnosis  Parts may need to be re- ordered  Projected re-evaluation on Sat.
