title: Selection of human consumables for future space missions.
abstract: Consumables for human spaceflight include oxygen, water, food and food packaging, personal hygiene items, and clothing.  This paper deals with the requirements for food and water, and their impact on waste product generation.  Just as urbanization of society has been made possible by improved food processing and packaging, manned spaceflight has benefitted from this technology.  The downside of this technology is increased food package waste product.  Since consumables make up a major portion of the vehicle onboard stowage and generate most of the waste products, selection of consumables is a very critical process.  Food and package waste comprise the majority of the trash generated on the current shuttle orbiter missions.  Plans for future missions must include accurate assessment of the waste products to be generated, and the methods for processing and disposing of these wastes.
