Samantha Cristoforetti is an Italian astronaut with the European Space Agency. She currently holds a few spaceflight records — including being the first person ever to brew an espresso in space. In 2014 and 2015, Cristoforetti spent 199 days aboard the International Space Station, where she performed a variety of scientific experiments. She studied generations of fruit flies to chart gene changes in relation to disease; she looked after Caenorhabditis elegans worms used in a Japanese-led experiment; and she tended to plants to study how they grow in microgravity. Cristoforetti was supposed to return to Earth in May 2015, but her stay on the ISS was extended to June after a cargo ship flying on a Russian Soyuz rocket failed to reach the space station. The delay extended Cristoforetti’s stay to 199 days, allowing her to collect the record for the longest single spaceflight by any female astronaut. (NASA astronaut Sunita Williams had previously held the record, at 195 days.) Cristoforetti’s record won’t last for long, though. NASA astronaut Peggy Whitson, who’s currently on the ISS, will soon surpass her. One of her records, however, will stay forever. Shortly before retuning to Earth, Cristoforetti used a coffee machine called ISSpresso to brew the first ever espresso in space. She then put on a Star Trek uniform top and used a special zero-gravity cup to sip it. Cristoforetti is not scheduled for another flight to the ISS for now, but she keeps working at the European Astronaut Centre in Cologne, Germany. Here, she works on new technologies that could one day be used for a future mission to the Moon. She’s “definitely” looking forward to going to space again though. “Hopefully it’ll be my turn again eventually,” she says. In the meantime, The Verge spoke with Cristoforetti about how she became an astronaut, what scientific experiments she performed on the ISS, and what happened to that famous space espresso machine.
