Capsule coffee machine: astronauts' espresso desire is answered
|
Version 0 of 1. The International Space Station is getting a real Italian espresso machine. Astronauts of all nationalities – but especially the Italians – have long grumbled about the tepid instant coffee served in pouches and drunk with straws 260 miles above Earth. The pouches and straws aren't going away, but at least the brew will pack some zero-gravity punch. The specially designed espresso machine is dubbed ISSpresso – ISS for International Space Station. Its launch early next year from Wallops Island, Virginia, is timed to coincide with the six-month mission of Italy's first female astronaut, Samantha Cristoforetti. The 37-year-old fighter pilot and air force captain will fly to the space station in November on board a Russian capsule. "How cool is that?" she tweeted this month. "I'll get to operate the first space espresso machine!" An Italian coffee maker teamed up with a Turin engineering company and the Italian space agency to improve coffee conditions aboard the orbiting outpost. During his 5½-month stay on the space station last year, the Italian astronaut Luca Parmitano repeatedly talked about missing espresso. Nasa's coffee-loving astronaut Donald Pettit offered some ideas for ISSpresso during its design phase. He's a two-time space station resident who invented and even patented a zero-gravity cup for sipping coffee rather than sucking it through a straw. No question, an espresso machine will be "a welcome addition" to space station life, Pettit said on Wednesday from Johnson Space Centre in Houston. The pre-measured bags of freeze-dried coffee served in orbit taste good – when you're up there on the frontier, he said. On Earth, any coffee lover would go "Yeeck." An Argotec spokesman, Antonio Pilello, has sampled the ISSpresso espresso and gives it a thumbs-up. The space machine is designed to operate at the same temperature and pressure as Earthly espresso makers, according to the company, to guarantee taste and flavour. "You know, coffee is very important for Italian people. We are really hard to please about it!" Pilello wrote in an email. Certified for safety and approved by Nasa, ISSpresso will initially fly with 20 coffee capsules. Extra packets will follow for the six-member crew, if the trial run goes well. The 20kg (44lb) machine – a compact 35cm (14in) by 44cm (17in) – will be housed in the US laboratory, Destiny. It resembles a microwave oven, with all the action occurring inside. Engineers replaced the typical plastic tubing in an espresso machine with steel for robustness. They also used buttons and switches similar to those already on the space station, so the astronauts would be familiar with the design. Astronaut Pettit points out that the lack of gravity will prevent the bubbly foam from rising to the top. Yet even if the space espresso falls short by connoisseur standards, "it would be the best coffee that we've ever had in space." |
