| Nov 3, 2020 at 23:12 | comment | added | uhoh | speaking of reaction wheels: Why are some reaction wheels sealed with low pressure gas, others with vacuum? I need a good talking-to about the effects of total pressure versus partial pressure on the evaporation rate and redeposition dynamics of large molecules! If an answer to that can support a full post, let me know and I ask about that specifically in a new "space grease dynamics" question post. | |
