From Ground to Orbit: The History of Coffee in Space
The history of space exploration is replete with remarkable feats of human ingenuity, and the inclusion of our beloved beverage – coffee – is no exception. Let’s take a look at how coffee has accompanied humans from the ground to the orbit.
Coffee and the Early Days of Space Exploration
In the nascent stages of space exploration, astronauts had to forego many earthly comforts, and unfortunately, freshly brewed coffee was among them. The initial solution was an unsatisfactory one – instant coffee packed in aluminum tubes. These tubes contained a freeze-dried coffee powder that astronauts could consume by adding water available on the spacecraft. Despite its practicality, this early version of space coffee failed to replicate the flavor and experience of a traditional earth-bound brew, signifying the need for an enhanced cosmos brewing method.
The Evolution of Coffee Consumption in Space Missions
As space missions became more advanced, so did the options for coffee. By the time of the Space Shuttle Program in the 1980s, space food technology had made significant strides, enabling astronauts to enjoy a slightly more sophisticated version of coffee. (1) They had access to a pouch of freeze-dried coffee to which they could add hot water via a specially designed port. This ‘wet’ coffee, though a significant improvement from the coffee tubes, still lacked the taste and aroma of a freshly brewed cup of coffee.
The real breakthrough came with the advent of the International Space Station. Thanks to international collaboration, especially with nations like Italy, known for their coffee culture, astronauts could look forward to better-caffeinated beverages. This push for better space coffee led to an exciting evolution of coffee in space.
Modern-Day Space Coffee: ISSpresso
The dawn of the ISSpresso machine marked a new era in cosmos brewing. A result of a collaboration between Italian coffee giant Lavazza, engineering company Argotec, and the Italian Space Agency, the ISSpresso is a specially designed espresso machine that operates under microgravity conditions. This device allows astronauts to make a variety of coffee drinks, from a simple espresso to a more complex caffe latte, right on the ISS. (2)
The ISSpresso heats water and forces it through a capsule of coffee grounds at high pressure, not unlike an Earth-based espresso machine. The coffee then dispenses into a special pouch, which astronauts drink from using a straw. This revolutionary development means that astronauts can now enjoy a taste of home, a true espresso, hundreds of miles above the Earth.
From instant coffee tubes to a dedicated espresso machine, coffee’s journey in space mirrors humanity’s own progress in exploring and adapting to the cosmos. The future of coffee in space promises even more intriguing possibilities as we continue to extend our reach into the universe.
Coffee Brewing and Consumption in Zero Gravity
When it comes to brewing and enjoying a cup of coffee, the laws of physics on Earth are our friends. Gravity assists the flow of water through the coffee grounds and into the cup, while the aroma of freshly brewed coffee wafts towards our noses. But when it comes to brewing coffee in the cosmos, the game changes entirely.
The Challenges of Brewing Coffee in Space
Cosmos Brewing presents a unique set of challenges due to the absence of gravity. Firstly, boiling water behaves very differently in space compared to Earth. Without gravity to draw steam upward, bubbles stay where they are, disrupting the uniform heating of water. Similarly, in zero gravity, water doesn’t flow but forms spheres due to surface tension, making it challenging to pass through coffee grounds as we do on Earth.
Besides, containment becomes an issue as fluids and loose coffee grounds can float around, posing a danger to both astronauts and the delicate electronics aboard the spacecraft. Also, maintaining the quality and taste of coffee is a significant hurdle, as the storage and brewing conditions are vastly different from what we’re accustomed to on Earth.
The Innovative Design of Space Coffee Cups
One of the most innovative solutions to tackle the challenges of coffee consumption in space is the specially designed space coffee cup. These cups are a remarkable blend of coffee connoisseurship and fluid dynamics.
Unlike regular cups, space coffee cups are 3D-printed with a specific shape that exploits surface tension, wetting conditions, and the unique properties of the fluid in a zero-gravity environment. (3) The sharp inner corner of the cup helps drive the coffee toward the mouth through capillary action. This innovative design allows astronauts to enjoy their coffee in a cup, not a bag, which enhances the sensory experience and makes sipping coffee in space feel a bit more like home.
How Astronauts Actually Drink Coffee in Space
Despite the innovative space coffee cups, most of the time, astronauts drink their coffee from specially designed pouches with a straw to prevent spills in the zero-gravity environment. After brewing the coffee using machines like ISSpresso, the coffee is dispensed into these sealed pouches.
The straw used to drink coffee has a unique design with a clippable end to prevent the liquid from floating out in the microgravity environment. To drink, astronauts clip open the straw, sip their coffee, and then close it back to maintain a clean and secure environment.
The fascinating journey of brewing and consuming coffee in space is a testament to human ingenuity in adapting to the challenges of space life. As we continue our cosmic journeys, the art of cosmos brewing will only get more exciting and sophisticated.

The Science of Taste: Coffee Flavor in Space
It might surprise you to know that coffee, one of the most beloved and flavorful beverages on Earth, tastes significantly different when consumed hundreds of kilometers above our planet. Let’s explore how space travel influences the taste of coffee and how the beverage contributes to astronaut morale and overall space mission success.
How Microgravity Impacts Taste Perception
The microgravity environment in space affects an astronaut’s body in various ways, including their senses. Taste is notably influenced by this zero-gravity condition. When astronauts go to space, they experience a shift in bodily fluids toward the upper body and head due to the lack of gravity. This fluid shift can lead to congestion, much like having a cold, which can dull the senses of taste and smell. (4)
As a result, astronauts often report that food and beverages, including space coffee, taste blander in orbit than they do on Earth. The flavors don’t resonate as much, leading to a less satisfying coffee experience. That’s why space food and beverages often lean towards strong, spicy, and rich flavors – to compensate for this sensory shift.
The Role of Coffee in Maintaining Astronaut Morale
Despite the challenges with taste perception, coffee holds a unique and cherished place in astronauts’ daily routines. The act of sipping coffee, even in space, provides a comforting sense of normalcy in an environment that is anything but normal.
Coffee’s role extends beyond just a caffeine boost. It’s a psychological tether to Earth and a brief respite from the rigors of space missions. The familiar ritual of preparing and drinking coffee can alleviate feelings of isolation and homesickness, contributing significantly to the mental well-being of astronauts.
The Future of Flavor Enhancements in Space Coffee
To combat the dulling of taste in space and to make space coffee more enjoyable, scientists are constantly looking for ways to enhance the flavor of coffee in orbit. Future research and innovations could bring more advanced brewing techniques, flavor enhancement methods, and even special coffee varieties selected or engineered specifically for space brewing.
One such possibility might be to use naturally stronger flavored Robusta beans instead of the typical Arabica coffee. Alternatively, research into how to safely and effectively introduce aromatic compounds into the brewing process could result in a richer, more flavorful space coffee.
As we continue to explore the cosmos and enhance our understanding of life in space, the humble cup of coffee, an emblem of our terrestrial lives, will evolve along with us.
