FYI: The Space Station now has it's own expresso machine.

the first time didn't work and the second try was delayed, but it has finally arrived

and yes, it is a scientific breatkthrough:

It is the first coffee machine able to work in micro gravity on the ISS, where the principles that regulate the fluid dynamics of liquids and mixtures are very different from those typical on Earth.It uses a 'capsule system' to fill plastic pouches with espresso and other hot drinks such as tea.The machine can also be used to rehydrate food.
of course astronauts need a special coffee cup to drink the stuff. 
DaveReneke explains here.

In space you don’t sip, you suck, from a bag. That’s a good thing. The typical coffee cup simply doesn’t work in low gravity, unless you want scalding hot liquid floating through the air. It takes a special vessel to get liquid from an open container into an astronaut’s mouth.
It also takes a helluva lot of science, as seen by the cup designed by Portland State University researchers. For the past year, scientists there have been developing a mug designed specifically to allow astronauts to sip on espresso (or other warm and frothy drinks) in low-gravity environments. The cup’s shape is odd—a little like a plastic baby boot—and was determined by mathematical models.
Every curve and geometric shape is designed to encourage the controlled movement of liquid. You’ll notice a pointed corner in the center of the cup; this strange bit of design is what makes it possible to drink liquids in low gravity. The corner essentially acts like a wick, using surface tension to guide liquid toward your mouth.

and to go with it, the Swedes have launched the first donut in space.
