Space Cowboys
Mission Overview• Objective
– Accurately measure flight parameters including ambient and skin temperatures, pressure, acceleration, spin rate, and magnetic field.
– Gain basic understanding of design requirements and associated hurdles for designing in real-world space applications.
Mission Overview• Goal
– Provide an accurate base of flight parameters to model rocket flight conditions and patterns for assessment of associated affects on other systems.
– Attain real-world design experience.
Mission Overview• Underlying Science/Theory
– Recognition of magnetic field changes associated with altitude
– Quantification of varying flight parameters– Attempt to determine rocket orientation using
post-flight accelerometer data

RockSat Payload Canister User Guide Compliance
• Mass/Volume– Estimate 3lbs
• Payload Activation– G-switch activation
• Open circuit until g-switch activation
• Rocket Interface– RBF/Shorting wires
Shared Can Logistics Plan• University of Wyoming (UW) & University of
Minnesota (UMN)• UW Missions
– Multi-sensor: Rocket flight parameter measurements– Explore rocket flight effects on electrical and crystal
oscillators• UMN Mission
– To characterize the flight of the rocket and attempt to record data using techniques untested in suborbital flight.
Shared Can Logistics Plan• Interfacing Collaboration Plan
– E-mail and phone conferencing– Exchange of 3D modeling suggestions– Full assessment and agreement on location,
structure and interface
• Structural Interfacing– Still to be determined

Management• Project Schedule
– See attachment
• Preliminary mass/monetary budgets– Mass Budget: 3lb (Multi-Sensor)– Budget: approx. $500
Conclusions• Issues/Concerns
– Structural Interface with other Payloads within Canister
– Electrical Interference from Payloads and External Radiation
