The heroic vision of our astronauts, grave and flawless, drinking their own recycled urine or sometimes powdered grape juice, seems a little quaint these days … since Perestroika we have become familiar with the Russian cosmonauts’ talents in the art of hiding bottles of vodka between compartments full of electronics aboard the Soyuz spacecraft. These days, space flights have become so commonplace that this prohibition, which was only ever for form’s sake, has been lifted … this time in the interests of scientific research. In the name of science, vats of beer and litres of wine will be allowed on the international space station, although, for now, only in order to carry out tests on “germination and gene-expression in microgravity.”
