- Topics
(with thanks to Herman M., Michael F., and Doug S.)- comparison among instruments and missions
- chemical composition
- time dependence
- spatial dependence (
- Constraints on chemical composition and variation among spacecraft.
- The variety of time dependences that are expected and observed.
- Spatial variations on micron to cm scales.)
- Contamination mitigation (for current and future missions).
- 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)
- procurement
- ground procedures
- ground testing and calibration
- on-orbit monitoring
- where contamination is observed, along with environmental data like temperature (maybe pressure)
- where the coldest surface is located
- lessons learnt, recommendations on design, procurement, procedures, etc.
- any ideas about composition of contaminant
- time dependance (maybe special events ...)
- how it affects science data (what celestial sources are proper monitoring targets)
- comparison among instruments and missions
