Notes

• Mission Requirements
  • Pump
  • Thermal
  • Servos for turning cylinder/baffles
  • Sensors
  • On-board computer (OBC), if necessary
  • Valves for pressure release
• Operational Modes
  • Idle/safe mode
  • Science mode
  • Programming mode
  • Any other modes that we so desire!
• Power
  • Peak current
  • Peak voltage
  • Duty cycle
    • Everybody should do some research into this on their own!
• Protection/Reliability
  • Protection from magnetic, electrical, and thermal interference
  • Safety limits
  • Redundancy
  • "Graceful failure" - ensuring that any failures do not compromise the entire system
  • Testing
  • Noise reduction
  • Data logs
    • Work with data management
• Harnessing
  • Data paths
  • We need to consider any magnetic interference when we route wires. For instance, we shouldn't route wires near sensors or PCBs.
  • Work with Structures to plan out harnessing in advance
• On-board components
• Environmental
  • Account for environmental factors such as:
    • Thermal
    • Radiation
    • Electronics in a vacuum
      • Outgassing
      • Ensuring that certain components (such as capacitors) will work in a vacuum
• Testing Plan
  • Work with Testing & Manufacturing
• Integration Plan
  • Work with Oligo

Next Steps

• Create block diagram(s)
• Research space-rated components
  • Look into radiation hardening. Do we need to do it in-house? What are our requirements for maximum radiation dosages? What about shielding thicknesses?
• Communicate with other subteams to get information about sensors, servos, etc. We should compile a list of the datasheets for all of the peripherals that we need to work with.
