"NASA has included a total of 43 servings of coffee for the four astronauts."
but ... but it's a ten day mission 
Andrew@pamela Not directly related to your point but: I'm sure they do count "days" up there but like technically I guess it's more of a 240-hour mission?
Does seem like at most two of the astronauts can be coffee people, though, for that to be reasonable.
