2.  Mission Statement The GONS project includes sending a satellite to Near Space to conduct experiments regarding stabilization and CCD camera imaging.  Expected Results  Maintain an internal temperature above 0ºC for duration of flight  Reduce rotation about the vertical axis by 50%  Capture and record video of entire ascent and descent  Mission Statement The GONS project includes sending a satellite to Near Space to conduct experiments regarding stabilization and CCD camera imaging.  Expected Results  Maintain an internal temperature above 0ºC for duration of flight  Reduce rotation about the vertical axis by 50%  Capture and record video of entire ascent and descent

3.  Stabilization about the vertical axis  Inertia wheel used in attempt to stabilize BalloonSat  Mylar space blanket used for insulation  Power usage the same (5 Lithium-Ion Batteries)  Foam core structure  Same basic internal components  Stabilization about the vertical axis  Inertia wheel used in attempt to stabilize BalloonSat  Mylar space blanket used for insulation  Power usage the same (5 Lithium-Ion Batteries)  Foam core structure  Same basic internal components RFP Compliance

4.  No CO2 thrusters, Photovoltaic Cells, or Live Communication  Added Accelerometer  Team-built Gyroscopes, Instead of Pre-built One  No Timing Circuit  Tubing from Plastic to Aluminum  No CO2 thrusters, Photovoltaic Cells, or Live Communication  Added Accelerometer  Team-built Gyroscopes, Instead of Pre-built One  No Timing Circuit  Tubing from Plastic to Aluminum RFP Differences

12.  Success: Basic Mission Objectives Accomplished  Mass, Budget, Internal Temperature  Success: Video Capture of Entire Flight  Recorded Continuously from 7:12 a.m. to 11:22 a.m  Failure: Reduce Effect of Forces Acting Upon Satellite  Heater and Ball Bearings Became Dislodged  Not Enough Mass Allocated Towards Flywheels  Success: Basic Mission Objectives Accomplished  Mass, Budget, Internal Temperature  Success: Video Capture of Entire Flight  Recorded Continuously from 7:12 a.m. to 11:22 a.m  Failure: Reduce Effect of Forces Acting Upon Satellite  Heater and Ball Bearings Became Dislodged  Not Enough Mass Allocated Towards Flywheels Conclusions

13. Ready To Fly Again  Heater Fell From Ceiling  Glue Adhesive Section of Velcro to Insulation  Bearings Attachment  Integrate Bearings Directly into Foam Core Structure  Camera Lost Voltage Due to Temperature  Cover Batteries in Space Blanket or Insulation  Motor Vibrations Created False Accelerometer Readings  Other Means of Recording Rotation Measurements  Instrument Time Synchronization  Prior to Launch Synchronize Time on all Instruments  Heater Fell From Ceiling  Glue Adhesive Section of Velcro to Insulation  Bearings Attachment  Integrate Bearings Directly into Foam Core Structure  Camera Lost Voltage Due to Temperature  Cover Batteries in Space Blanket or Insulation  Motor Vibrations Created False Accelerometer Readings  Other Means of Recording Rotation Measurements  Instrument Time Synchronization  Prior to Launch Synchronize Time on all Instruments

14. Preparation for Next Launch  How Payload Should Be Stored  Close Lid to Minimize External Contamination  Indoors in Dry Climate  Remove Batteries  Immediately Prior to Launch  Turn on Camera then Recorder  Secure Top Lid with Aluminum Tape  Turn on External Switches  How Payload Should Be Stored  Close Lid to Minimize External Contamination  Indoors in Dry Climate  Remove Batteries  Immediately Prior to Launch  Turn on Camera then Recorder  Secure Top Lid with Aluminum Tape  Turn on External Switches

15.  Take the initiative  Teamwork and Responsibility Delegation  Organization  Documentation, Structured Meetings, Deadlines  Working Against the Clock  Keep It Simple Stupid  Take the initiative  Teamwork and Responsibility Delegation  Organization  Documentation, Structured Meetings, Deadlines  Working Against the Clock  Keep It Simple Stupid Lessons Learned

16. Message to Next Semester  Don’t Be Intimidated By Workload  Keep It Simple Stupid  Find Group Members’ Individual Strengths  Work Hard on Proposal, It’s Worth 10% of Final Grade!  Brainstorm Lots of Ideas Initially  Document Everything  Don’t Be Intimidated By Workload  Keep It Simple Stupid  Find Group Members’ Individual Strengths  Work Hard on Proposal, It’s Worth 10% of Final Grade!  Brainstorm Lots of Ideas Initially  Document Everything
