The document discusses a Canadian symposium on nutrition education programs for grades 2 through 10 and a student contest to design nutritious menus for an astronaut trip to Mars. It provides details on the nutrition education program, including that it is curriculum-based and web-based. It also outlines requirements for the student menu designs, including proposing menus that satisfy nutritional needs in a weightless environment and meet submission deadlines. The document then discusses nutritional challenges for astronauts, such as deficiencies from weightlessness and radiation, and how food is specially prepared for space, including removal of water, heating to kill microbes, and packaging to prevent crumbling.
