Space Coffee, Just the Way You Like It 147

Zothecula writes "Since the early days of space travel, a consistent complaint has been lousy coffee. Now a group of freshman engineering students at Rice University have developed a simple approach to alleviating this problem. From the article: 'The challenge was to develop a method and equipment that allows astronauts to add liquid ingredients (cream, sweetener, and lemon juice) from a foil package to another that contains black coffee or tea. No spills in microgravity can be allowed, as these have a tendency to migrate into equipment and cause faults. The Rice freshmen designed their system around the existing black coffee pouches. NASA supplied them two-ply heat sealed pouches to hold the sugar syrup and cream. The beverage and condiment pouches all have a septum which allows access to their contents without allowing any of the liquid contents to escape.'"

        Bingo!

        Everyone seems to be hung up on coffee, as though that were the ONLY liquid that might ever need to be mixed with another ingredient in zero gravity.

        Hello, everyone! The same methods used to add cream to coffee will likely work in scientific experiments, or mixing epoxy cements, or, preparing an acid solution, or - just about anything that requires two ingredients to be mixed.

      I'm not even a rare-occasion coffee drinker so I'm hardly an expert on the chemistry, but might this be a situation similar to, say, two-part epoxy materials, where the desired result occurs at the time two compounds are mixed and doing that mixing prematurely leads to unacceptable consequences? Would coffee taste quite right if the additives were added weeks or months in advance of consumption?

      That's not what I was thinking. I was thinking, wouldn't it be substantially simpler just to ask them to tough it out for a while and drink black coffee? I've done deep field work and yes, it sucks, being without the comforts of home, but a few sacrifices need to be made. This one seems pretty darn tiny.

    • Well, I for one have tastes that change from day to day. Almost every time I make my coffee (which is about 6 to 8 times a day), I change something around. It's not that I absolutely MUST have variations in my coffee. But there's little joy in having the same stuff over long periods of time.

      But you do have a very valid point. They're on duty 24/7 in the ISS, and they knew what they were getting into well in advance. A rough blend in their preferred proportions would be a much better idea.

      • I'm totally opposite. I tend to find a flavor and have no problem eating the same thing day in and day out. When I drink coffee, I prefer it black and without variations of sugar or cream.

      • I hope you're only making coffee 6-8 times a day for yourself and not "experimenting" with the break room coffee.

        And if you are making it only for yourself... that might be too much caffeine. How do you sleep at night?

        • Yes, yes, for myself. :) Though this is when I'm not at work. The coffee at work is not what I'd call awesome, but it's not so bad that I don't touch the stuff.
          I make my own coffee when I'm at home, so I was not counting the coffee at work, which is about 4 cups on a good day.. many more on a bad one.

I assume they have more than just coffee available so I don't see why they can't pick a combination of sugars and cream for their coffee. I guess that's just me from the other posts here.

    • As others have mentioned there are other applications for this method, but sticking to the Coffee demonstration premixing foods for consumption in space is a bit tricky. Things don't taste quite the same in zero G as they do in a gravity environment for most astronauts. While the basic parameters are fairly well know (less sugar than normal, more spices than normal, etc) tweaking it for individual tastes could be difficult. I believe the aspects of this also change depending on how long the astronaut is

      A good rule of them for going into a dangerous environment is to get as much shit done as you can outside of it. If things are so strange up there that it's best to precook all your food I think premixing your flavored beverages is worth the effort to.
