Why Space Demands a Special Menu
Eating in space is nothing like dining on Earth. In the microgravity environment of a spacecraft, simple things become major hazards. Crumbs don't fall to the floor; they float, posing a risk to sensitive equipment and astronauts' airways. Liquids escape
from open containers, and even the astronaut's body changes. Bodily fluids shift upwards, causing a stuffy-nose sensation that dulls the senses of taste and smell, making food seem bland. Furthermore, all food must be lightweight, compact, highly nutritious to combat muscle and bone loss, and have a long shelf life without refrigeration. These constraints mean that every single meal has to be carefully engineered for safety, nutrition, and palatability.
The Science of Indian Space Food
The task of creating this specialised menu for Gaganyaan falls to the Defence Food Research Laboratory (DFRL) in Mysuru. This DRDO lab, with decades of experience in creating food for soldiers in extreme conditions, is using advanced food technology to prepare Indian cuisine for orbit. The primary methods are thermostabilisation and freeze-drying. Thermostabilised, or ready-to-eat, food is heat-treated in pouches to kill microbes, allowing dishes like biryani or dal to be stored at room temperature. Freeze-drying involves removing water from cooked food, making it extremely lightweight. Astronauts rehydrate these meals in space using a water dispenser. These processes ensure the food is safe, easy to store, and retains much of its nutritional value and flavour.
A Taste of Home in Zero Gravity
So, what's on the menu for India's astronauts? The DFRL has developed an extensive list of over 30 dishes that balance the technical requirements of space with the familiar tastes of home. The approved list includes comforting staples like idli sambar, upma, veg pulao, chicken biryani, dal-rice, and moong dal halwa. Also included are veg rolls, chicken korma, and even mango pickle to add a much-needed flavour kick. Chapattis have been specially formulated to last longer and produce minimal crumbs. These meals are designed to be mildly spiced, with optional spice sachets, catering to the altered taste perception in space. Even beverages like juices and tea are provided in specially designed containers with straws to prevent spillage.
More Than Just Nutrition
Food in space serves a critical psychological function. Being isolated hundreds of kilometres from Earth can be mentally taxing, and familiar food provides a powerful sense of comfort and connection to home. It boosts morale and helps combat 'menu fatigue', a common issue on long missions where astronauts grow tired of a repetitive diet. Sharing a meal is a universal social ritual, and for the Gaganyaan crew, having dishes like khichdi or chicken korma will be a way to maintain normalcy and camaraderie. It’s a reminder that even in the most sterile, high-tech environment, a taste of home can make all the difference for an astronaut's well-being and performance.
