  • Topics
    (with thanks to Herman M., Michael F., and Doug S.)
    • comparison among instruments and missions
      • chemical composition
      • time dependence
      • spatial dependence (micron to cm scales)
      • temperature dependence (where is the coldest surface?)
      • environmental dependence (orbit)
    • mitigation for current instruments
      • celestial monitoring targets
      • effects on calibration and science results
      • "bake-out" procedures
    • mitigation for future instruments
      • design (cold traps, contamination blocking filters)
