Recent studies have found that astronauts can lose up to 9% of their hip bone density after just six months in space, mirroring the accelerated aging process predicted for life on the red planet. This provides a glimpse into what does Mars do to your body, where lower gravity and higher radiation will dramatically affect human health over time.

On April 12, 1961, Soviet cosmonaut Yuri Gagarin made history as the first human in space, and during his 108-minute mission, he also became the first person to eat in orbit. His menu was a far cry from modern astronaut meals, consisting of pureed beef and liver paste from a toothpaste-like aluminum tube.

Astronauts consume roughly 1.7 kilograms (3.8 pounds) of food each day, including packaging. This daily amount is carefully planned to meet their nutritional needs.

According to NASA, the International Space Station stocks about 3.8 pounds of food per astronaut per day, along with extra supplies to support unexpected mission extensions. This comprehensive preparedness means crews are highly unlikely to face starvation.

The menu on the International Space Station (ISS) features over 100 food items, reflecting decades of advancement. While it's no five-star restaurant, the answer to what food do space Travellers eat involves a meticulously designed diet to ensure health, psychological well-being, and ease of consumption in microgravity.

Astronauts consume a significant amount of food, often between 2,500 and 3,800 calories each day, depending on their activity levels. The question of how much food astronauts eat involves the unique aspects of eating and nutrition in space.

Astronauts aboard the International Space Station (ISS) typically need between 2,500 and 3,800 calories per day, a range that often surpasses their pre-flight needs on Earth. This increased energy requirement is a direct result of the unique physiological and environmental challenges of living and working in microgravity, which directly impacts how many calories does an astronaut need in space.

Astronauts burn significantly more energy in microgravity, with some needing up to 4,000 calories a day, far exceeding the average Earth-based requirements. The primary reason for why astronauts need so many calories in space is the profound physiological adaptation their bodies undergo to survive in a weightless environment.

Over 300 different food items are available on the menu for astronauts on the International Space Station (ISS), a far cry from the pureed pastes of the early space programs. This vast improvement in variety and palatability showcases the complex engineering involved in addressing the question of how do astronauts eat their food in space.

During her extended stays on the International Space Station, NASA astronaut Sunita Williams relied on a meticulously planned diet of freeze-dried meals, pre-cooked dishes, and limited fresh produce, as well as recycling water from her own sweat and urine for hydration. These methods are crucial adaptations to living and eating in a microgravity environment.
