13. Payload Science payload consists of: – Flight computer number 1 – Flight computer number 2 – Embedded microcomputer system – Radiation counter – Temperature sensor – Pressure sensor – x-, y-, z- accelerometers – Battery power supply

14. Payload Science instruments, flight computers, recovery transmitter and batteries fit inside 3.78 in diameter by 12.0 inch long phenolic coupler tube Switches,status LEDs, computer connectors mounted on ring in the middle of the coupler

15. Payload Side profile of science payload with circuit boards and batteries mounted

16. Payload 9-Volt Battery Pack on leftPefectflite Computer on bottom right G-WIZ FlightComputer on top right

17. Payload Geiger counter and x-, y- accelerometers on right Z- accelerometer in middle Embedded controller, temperature and pressure sensors on right

18. Payload Science Payload Objectives. Test and calibrate a Geiger-Mueller radiation counter Interface Geiger counter to embedded controller to operate the instrument and collect and store the data. Test the complete instrument mounted in the airframe using laboratory alpha, beta and gamma radiation sources. Test and calibrate pressure sensor Test and calibrate a temperature sensor Test and calibrate a low sensitivity and a high sensitivity 3- axis accelerometer

19. Payload State the payload success criteria Payload success will be achieved if all the sensors perform satisfactorily and data from each is collected and stored in the on-board computer memory.

20. Avionics The recovery subsystem is composed of the following components: PerfectFlite MiniAlt/WD to measure and store altitude and deploy drogue and main parachutes. DT2x Data Transfer Kit for connecting MiniAlt/WD to computer G-Wiz MC-2.0 Flight Computer to provide redundant backup of the PerfectFlite Nine pin female to female cable with subminiature D connectors to connect G-Wiz MC-2.0 to computer

21. Avionics Software to download data from G-Wiz Ejection charges with electric matches to deploy parachutes SkyAngle Main Parachute with 57 square feet SkyAngle Drogue Parachute with 6.3 square feet Shock cord – to be determined Walston Retrieval System with Rocket Transmitter, 3-Channel Receiver, and 3-element Antenna

22. Avionics Dual Deployment Avionics Test Test planned for middle of February PerfectFlite MiniAlt/WD Official USLI Altimeter and Flight Computer

23. Avionics G-WIZ MC-2 Backup Altimeter and Flight Computer

25. Launch Operations We plan to assemble the motor ahead of time, so that all we have to do is load the nitrous Draft Launch Plan in Appendix A in CDR, Page 29

26. Recovery Ejection Charge Amount Test Test planned for middle of February Walston Retrieval System for Rocket Locating SkyAngle 24 in for Drogue SkyAngle Large Cert-3 for Main

27. Outreach The timeline with major milestones is on page 5 The milestones accomplished are grayed out in the table We are behind in launching scale model rocket We are slightly behind in the construction of the airframe We are behind in writing procedures needed We are behind in outreach with the Girl and Boy Scout Programs.

28. Outreach We are excited about a rocket display in the Harding University Library in late February We have applied to be introduced with a program in Harding University Chapel that could potentially reach more than 5000 students We will be giving talks and posters on the USLI Program at Arkansas Undergraduate Research Conference and Sigma Xi Poster

29. Outreach Funds have been obtained to do an excellent job on this project. We acknowledge the Arkansas Space Grant Consortium for funding all 4 years of participation
