Why Are Astronauts’ Coffee Cups Different?

In a zero-gravity environment Liquids behave differently, making drinking very difficult. A regular coffee cup can cause hot liquid to float in the air.

As you can imagine, something like this happening in space is quite dangerous. OK but What is the feature of this cup?

Researchers from Portland State University have developed special cups so that astronauts can drink beverages such as espresso in a low gravity environment.

Let’s face it, the shape of the glass is a bit strange, and we wouldn’t be wrong if we say it almost resembles a toy. However There is a very important reason for its shape.

Every curve and geometric shape, to allow the fluid to move in a controlled manner designed. The pointed corner in the middle of the glass is a key design feature that allows liquid to move towards the astronaut’s mouth.

As soon as the astronaut’s lips touch the edge of the glass, a capillary connection occurs and the liquid moves upwards. It makes sippable coffee balls.

Seems simple right? In fact, in a zero-gravity environment Considered how liquids move We can call it a design.

But why was there such a need?

The foundations of the project were discovered by astronaut Don Pettit in 2008. Designed for coffee on the ISS It is based on a low gravity cup.

After Italy announced that it planned to send an espresso machine to the ISS, the Portland team began working to solve the problem. Well Astronauts bored of drinking coffee from plastic bags Such a glass was invented for
