A Taste of Home in Orbit
The menu for India's astronauts, or 'Vyomanauts', is far from bland. Developed by the Mysuru-based Defence Food Research Laboratory (DFRL), the spread is designed to provide a comforting taste of home millions of miles away. The extensive menu includes
familiar favourites like vegetable biryani, chicken biryani, aloo paratha, dal chawal, and sambar chawal. For breakfast and snacks, astronauts can look forward to dishes like idli, upma, and veg katti rolls. For those with a sweet tooth, options like sooji halwa and moong dal halwa are also on the list. The goal is to provide variety and familiar flavours, which is crucial for morale and psychological well-being on long and isolated missions.
The Science of Space-Ready Food
Preparing food for space is a complex scientific challenge. Every item must be lightweight, compact, highly nutritious, and have a long shelf life. The DFRL, which has experience developing food for soldiers in extreme environments, uses processes like thermostabilization (heat treatment) and freeze-drying to preserve the meals. The food is specially prepared to be low-fragmentation, meaning it won't create crumbs. In zero gravity, floating crumbs are a serious hazard as they can be inhaled by astronauts or damage sensitive equipment. The dishes are also made to be mildly spiced, as microgravity can alter an astronaut's sense of taste and smell, often making food seem bland. Astronauts will have spice sachets if they prefer an extra kick.
Dining in a Zero-Gravity Environment
Eating in space isn't just about the food itself; it's also about the mechanics of consumption. In zero gravity, liquids don't pour, they form floating globules, and food can drift away from the plate. To counter this, liquids like water and juices are packaged in special containers that are drunk with a straw. Solid foods are often in paste or semi-solid forms and are consumed directly from specially designed packets. The DFRL has also developed food warmers to allow the crew to have hot meals. Even the cutlery is specially designed, and waste disposal is a meticulously planned process to keep the spacecraft's environment clean and safe.
Nutritional Needs Above the Clouds
An astronaut's diet is scientifically calibrated to counteract the negative effects of microgravity on the body. Without the constant pull of gravity, astronauts experience muscle atrophy and bone density loss. To combat this, their diet must be carefully managed. They require a daily intake of around 2,500 to 3,200 calories, depending on their body mass and activities. The food is engineered to be rich in nutrients like calcium and vitamin D to support bone health. Protein intake is also crucial for maintaining muscle mass. Every meal is part of a larger health maintenance plan to ensure the crew remains fit and functional throughout their mission.
The Psychological Comfort of Food
Beyond nutrition, food plays a vital psychological role for astronauts. In the isolated and high-stress environment of a spacecraft, a familiar meal can be a significant source of comfort and a morale booster. The choice to include a wide range of popular Indian dishes, and even pickles, is a deliberate one. It connects the astronauts to their culture and provides a sense of normalcy. This has been a key consideration in space travel since the early days, with space agencies worldwide recognising that the quality, taste, and variety of food directly impact crew performance and well-being.
