The long-term survival of humans in extreme environments requires thorough preparations and high-quality food products. The food needs to be nutritious, easily transportable (both light and compact) and flavorsome. When performing long duration expeditions and simulated space missions, humans need nutrition that fulfils their needs, all while being enjoyable enough to motivate them to eat regularly. These extreme environments, whether they are places in challenging conditions on Earth or in space, also make it difficult to store food. Nutritional products for humans on these expeditions thus also need to be able to be shelf-stable without losing their nutritional value. Dr. Michaela Musilova will share her experiences with food while leading over 30 simulated missions to the Moon and Mars, and while leading various expeditions to some of the most challenging environments on Earth.
