[FPSPACE] Two Apollo 9 EVAs?

[Jonathan McDowell]

Right, Jim's examples are good ones.
So the Mir hatch swap EVAs count by the Depress-Event rule and the
Open-to-Outside rule but not the Outside rule. The Spektr repair
counts by the Depress-Event rule but not by the Open-to-Outside rule.
The Gemini equipment dumps are like the Mir hatch swap EVAs.
STS-80 is like the Spektr case. 

STS-31 is an interesting case of a partial depressurization.
I have a list of these:
 Gemini 10 suit/ECS test, partial depress to 200 mbar
 Apollo 10 tunnel venting, partial depress to 240 mbar
 STS-31 aborted EVA, partial depress to 345 mbar
 Mir EO-24 delayed EVA for glove repair, down to 50 mbar then back up. (Vinogradov/Solovyov)

This list may not be complete. Definitely there are some interesting
marginal cases.
