When astronauts in the Orion spacecraft travel beyond the moon to explore deep space destinations, they’ll need a robust diet to keep them healthy and sharp. Crew members aboard ISS can choose from approximately 200 items for their meals and have the space to stow an array of options. Orion has limited room inside it to accommodate the supplies and food astronauts will need during their missions. Because flights to deep space will not rely on resupply spacecraft to deliver what astronauts need and dispose of trash, the Orion crew will have to take everything they need with them and bring it all back home. Given the distances Orion will travel, teams also must limit Orion’s mass, since a heavier spacecraft requires more fuel and energy to propel it to its ultimate destination. To help reduce the amount of supplies Orion will carry for its crew, scientists are developing a variety of food bars (700-900 calories each) that astronauts can eat for breakfast during their spaceflight missio...
