1. Request for Proposal RFP# 2500F03 Radio Reception and Solar Power Balloon Satellite Radio Flyers Engineering is Chris Maytag, Challon Winer, Valerie Slasor, Hwapyong Ko, Kris Hodges and Brian Creber

2. To explore light propagation and radio propagation in the upper atmosphere. The satellite’s primary experiments are the measuring of radio reception/recording and solar radiation levels. Secondary experiments are humidity, pressure and temperature measurements. Mission Overview

3. Project Schedule 11.3.03: Pre-Launch Readiness Review 11.4.03-11.8.03: System Integration and System Testing 11.8-9.03: Complete Structure and Component Integration 11.8-9.03: Camera Test and Cold Test 11.10.03-11.18.03: Contingency Period 11.19.03: Final Launch Readiness Review 11.22.03: Launch Day

4. Current Status Hardware-all hardware acquired except plexiglass, mirror and pressure sensor Enclosure- construction completed (New Dimensions 10x15x15, Now using foamcore) Difficulties: very close to mass limit, mirror integration, power integration
