Astronauts Hacked a Space Coffee Cup for Caffeine in Orbit
Zero gravity didn't stop these pioneers from getting their brewed beverage
Drinking coffee in space is not easy. Liquids move, fly and float all sorts of directions without the proper vessel to contain them. In space, gravity is negligible, so liquid behaves differently.
Astronaut Kjell Lindgren missed good coffee while in orbit. The capillary beverage cup now makes it possible to brew coffee in space by making a slight adaption on a 3D-printed espresso cup created by Portland State University mechanical engineering graduate student Drew Wollman and his professor Mark Weislogel, by adding a modified brewer attachment. In the video below, a syringe is filled with hot water and the water is pumped through an attached coffee-pod (think K-cup), which creates freshly brewed coffee as it flows directly into the printed espresso mug.
