Making gravity-free espresso in space really is rocket science

Specially designed ‘ISSpresso’ machine overcomes absence of gravity by firing pressurised water through capsule of coffee

Perhaps one of the last barriers to the human conquest of space has been removed; a space-rated espresso machine has now been delivered to the International Space Station (ISS).

The device was made by two Turin-based companies, Lavazza Coffee and engineering firm Argotec. It is called the ISSpresso and was delivered by Italian astronaut Samantha Cristoforetti in the early hours of Monday morning, when her Soyuz space capsule docked at the orbiting habitat.

Making coffee in space is difficult, especially espresso, which relies on 94°C water being passed through ground coffee under high pressure.

On Earth this is achieved with the help of gravity. The ground coffee is placed in a perforated container, the water is heated and shot on to the coffee to drip into the cup. In space there is no up and down, so things don’t naturally fall.
