Space food systems are designed to provide astronauts with nutritious meals during space missions. These systems ensure that food is safe, lightweight, and easy to prepare in a microgravity environment. Various preservation methods, such as freeze-drying and vacuum sealing, are used to maintain food quality and extend shelf life. To support long-duration missions, like those to Mars, space food systems also focus on sustainability. This includes growing food in space using hydroponics or aeroponics, which allows astronauts to cultivate fresh produce. Research continues to improve these systems for future exploration and to enhance the overall health and well-being of crew members.
