Cape canaveral: The U.S. National Aeronautics and Space Administration (NASA) has unveiled the meal menu for the Artemis II mission, marking a milestone in space exploration. This mission, which involves four astronauts orbiting the moon for 10 days, highlights not only advanced aerospace engineering but also the meticulous planning that goes into astronaut nutrition under the constraints of the Orion spacecraft.

According to Thai News Agency, the primary challenge in designing the space menu is ensuring that meals are easily consumable in a microgravity environment. This is crucial to prevent food debris from potentially damaging sensitive electronic systems or posing a risk to the astronauts' respiratory health. To address these challenges, NASA has incorporated ready-to-eat foods, rehydrated meals, and foods sterilized by heat or irradiation. These preparations ensure that the astronauts' nutrition does not interfere with the spacecraft's operations or vital systems.

Space nutrition experts collaborated with astronauts to create a menu that balances necessary caloric intake, complete nutrients, and hydration levels. Meals are systematically scheduled for breakfast, lunch, and dinner, with each astronaut allowed only two cups of flavored beverages, such as coffee, per day. This restriction helps manage the spacecraft's payload limitations efficiently.

The Artemis II mission's menu showcases the evolution of space nutrition systems over decades. In contrast to the Apollo era's limited food technologies and the Space Shuttle era's increased menu options, today's International Space Station (ISS) benefits from regular resupply shipments that occasionally allow for fresh meal preparation. However, the Artemis II mission stands apart as it operates without a refrigerator or additional supply shipments. The fixed, pre-selected menu is crafted for a completely self-sustaining spacecraft, reflecting the mission's unique challenges and innovations.
