According to a Russian spokesman, there has been a near 50 percent increase over the last twelve months in the cost of rations, caused by price inflation on products used in making the rations, and rising costs of required testing and analyses.
"Last year, the cosmonaut's daily ration in space cost about 11,000 rubles (250 euros), and today the cost is reaching 15,000 rubles," said Viktor Dobrovolsky, director of the food institute that supplies space cosmonauts.
The weightless conditions onboard the ISS requires that some thought has to go into the provision of food for the astronauts to eat. Products that cause crumbs, like bread, are excluded as crumbs are light enough to simply float away and scatter throughout the space station, potentially clogging air vents, or contaminating equipment – instead tortillas are used as they have no crumbs, store easily, and of course, can double up as a frisbee for a bit of fun! For the same reason of float-ability, salt and pepper are provided in liquid form. Food consumed is generally better if it has a moist or sticky consistency, such as porridge, scrambled eggs, or pudding, as this type of food will stay on the spoon or fork.
