Active Cooling Systems

• Combination of fluid loops and TECs
  • TECs are potentially COTS (~$50)

Passive Cooling Systems

Thermal Straps

• Conductively transfer heat
• Doesn't add structural loads
• Blocks at ends of strap to be mounted

Thermal Louvers

• Regulate heat dissipation
• Function as shutters
• Typically associated with larger mass and power input

Deployable Radiators

• Dedicated surface for dissipating excess heat
• Stowed during transit and deployed when needed

MLI/Tapes/Film/Etc.

• Probably not helpful because would interfere with sun radiation (used to stratify temp)

Movement Control

• Use motor encoders to change angle
• Incremental encoder
• Absolute encoder - exact angle 
• Magnetic encoder - utilizes small magnet on shaft
