  1. Argus: SLU Core Bus Operational Test Steve Massey, Tyler Olson, Joe Kirwen, Wesley Gardner SHOT II Pre-Launch Presentation June 29, 2012

  2. Argus: Mission Statement The Argus spacecraft will improve the predictive performance modeling of radiation effects on small, modern space electronics by collecting radiation particle collision data from radiation modeling experiment electronics test beds and relaying the data to the ground. The Argus radiation payload is undergoing development at Vanderbilt University Senior Design Critical Design Review

  3. SCARAB: Mission Statement The purpose of Saint Louis University’s balloon sat test is to verify the functionality of the SLU Core Aerospace Research Application Bus (SCARAB), including implementations for both radiation modeling and infrared imaging in a space-like environment.

  4. Objectives: SCARAB • Demonstrate autonomous operations • Utilize data gathering and storage methods • Verify functionality of Communication system • S Band radio should demonstrate reliable 2-way communication • UHF beacon should send normally timed beacon packets receivable from the ground

  5. Objectives: Payload Operations Simulate operations between the SCARAB and Commodore, a radiation monitoring payload built by Vanderbilt University, outside of laboratory conditions An infrared imaging payload was included to capture images and test the capabilities of SCARAB to interact with and manage various payloads

  6. UN-7 Connection The SCARAB will be utilized on Argus as well as a much larger implementation of the radiation modeling experiment This will be an operational field test of the Argus spacecraft’s core functionality, primarily the CDH, Comm, and Power subsystems and how they interact with different payloads.

  7. Expectations • We expect to receive data from each radio within the first 20 minutes of flight. • We expect to be able to receive sensor data when prompted. • We expect seamless interaction between the radiation modeling payload and the SCB which will end in time-tagged event data saved to flash memory • We expect some interesting pictures

  8. Physical Design Outer Structure: Foam Board with insulating inside covering. Outer interface panel with LED’s and switches. All secured with gorilla glue, Kapton tape, electrical tape, and aluminum tape 16x16x20 cm housing protecting 10x10x10 cm payload 0.93 Kg- well under previous estimates

  9. Software-Mission Testing

  10. Hardware Testing Tests were conducted with an egg secured into the structure to test the structure’s shock-absorbing properties

  11. Special Thanks Thanks to Dr. Kyle Mitchell and Dr. Michael Swartwout for their mentorship Thank you the University Nanosat Program for this opportunity SHOT II Pre-Launch Presentation
