Close Encounters of the Food Kind
It is ironic that, in space, space is one resource at a premium – for astronauts at least. With refrigeration and freezer facilities making such a sizeable on-board footprint, astronauts currently live off dehydrated and pre-packaged foods. The technological processes involved in creating these products degrade the micronutrients in the food. NASA has been searching for alternative deep-flight sustenance for many years. 3D printing is just one option being considered but, if it succeeds, space pioneers might one day be printing their own salad (rocket?), sweets (flying saucers), and…you never know…maybe the odd pack of ‘Space Invaders’ too!
