New Delhi: ISRO Santulan programme has become a key focus area as the Indian Space Research Organisation (ISRO) prepares for Gaganyaan mission. ISRO has issued two tenders to create a personalized nutrition and meal support system for selected Gaganyaan astronauts, known as Gaganyatris, during their training at the Human Space Flight Centre (HSFC) in Bengaluru.
According to official tender documents released by ISRO’s Human Space Flight Centre, the initiative aims to ensure astronauts receive customized nutrition plans based on their health, training intensity, and mission requirements.
Why Is ISRO Creating A Special Nutrition Programme
Astronauts undergo physically and mentally demanding training before space missions. To support their health and performance, ISRO has launched a year-long initiative called Santulan, which will provide personalized nutrition support for the selected Gaganyatris.

The programme is designed to monitor and improve dietary habits, recovery, hydration, body composition, and overall fitness throughout astronaut training.
What Is The ISRO Santulan Programme
The Santulan programme will focus on creating individual nutrition plans for each astronaut. ISRO is seeking a nutrition consultancy that can provide four nutrition experts, including one dedicated nutritionist for each astronaut and one lead nutrition specialist. These experts will regularly assess astronaut health and modify diet plans whenever required.
Continuous Monitoring Of Astronaut Health
The nutrition plans will be based on detailed medical and physiological assessments. These assessments include:
- Blood markers
- Urine analysis
- Body composition measurements
- Metabolic rate evaluation
- Gut microbiome assessment
The collected data will help experts design highly personalized meal plans.
How Will The ISRO Santulan Programme Work
ISRO has clarified that astronaut diets will not remain fixed. Nutrition plans will be updated based on:
- Training schedules
- Recovery requirements
- Travel demands
- Feedback from astronauts
- Medical recommendations
This flexible approach ensures astronauts receive the right nutrients at the right time.
Scientific Nutrition For Peak Performance
The programme aims to optimize:
- Energy levels
- Muscle recovery
- Endurance
- Immunity
- Mental performance
Such support becomes especially important as astronauts prepare for the challenges of human spaceflight.
ISRO Also Looking For Catering Partners
