What Happened
- AIIMS New Delhi and ISRO signed a historic Memorandum of Understanding (MoU) on March 9, 2026, to collaborate on space medicine research — a critical requirement for India's human spaceflight programme.
- The MoU was signed between M. Srinivas, Director of AIIMS New Delhi, and Dinesh Kumar Singh, Director of ISRO's Human Space Flight Centre (HSFC).
- ISRO Chairman V. Narayanan and Secretary, Department of Space, attended the signing ceremony alongside senior leadership from both institutions.
- The collaboration covers ground-based and space-based research across multiple domains: human physiology in microgravity, cardiovascular and autonomic regulation, musculoskeletal health, microbiome and immunology, genomics and biomarkers, and behavioural health.
- The partnership is directly aimed at preparing India's astronauts (Gagannauts) for the Gaganyaan mission and building long-term institutional capacity in space medicine.

Space Medicine — The Science of Human Health Beyond Earth
Space medicine is the branch of medicine that studies and addresses the physiological and psychological challenges of spaceflight. Microgravity — the near-weightless condition in space — places extreme demands on the human body because it evolved under Earth's 1g gravitational field. Astronauts experience a cascade of physiological changes: fluid shifts toward the upper body (causing facial puffiness and vision problems), bone mineral density loss of roughly 1% per weight-bearing bone per month, skeletal muscle atrophy of up to 20% over a month, immune suppression, cardiovascular deconditioning, and alterations in gut microbiome composition. On return to Earth, readaptation can take weeks to months.
- Bone loss mechanism: in microgravity, bone-building osteoblasts slow down while osteoclasts maintain their resorption rate, producing net bone loss.
- Muscle loss: up to 30% decrease in average skeletal muscle strength over one month in space without countermeasures.
- Vision impairment: increased intracranial pressure in microgravity causes the optic nerve to swell — Spaceflight-Associated Neuro-ocular Syndrome (SANS).
- Countermeasures currently used: 2 hours of daily exercise (aerobic + resistance), dietary calcium and Vitamin D, pharmacological interventions.
- Space medicine findings have direct terrestrial applications in treating bone density loss (osteoporosis), muscle wasting conditions, and long-duration bed-rest patients.
Connection to this news: AIIMS brings world-class medical research infrastructure in exactly these domains — cardiology, neurology, immunology, and musculoskeletal medicine — making the AIIMS-ISRO collaboration a natural fit for developing India-specific space medicine protocols for Gaganyaan.
Gaganyaan — India's Human Spaceflight Programme
Gaganyaan is India's first human spaceflight mission, being developed by ISRO under the Human Space Flight Centre (HSFC). It aims to send a crew of three Indian astronauts (designated Gagannauts) to a Low Earth Orbit (LEO) of approximately 400 km for a mission duration of up to 7 days, before a splashdown in the Bay of Bengal. The mission has proceeded through several milestones: crew selection and training (completed in Russia and India), unmanned test flight with a humanoid robot (Vyommitra), and progressive crew escape system tests. Medical screening and health monitoring of the selected crew — Group Captain Prashanth Nair, Group Captain Ajit Krishnan, Group Captain Angad Pratap, and Wing Commander Shubhanshu Shukla — is a critical element of mission preparation.
- Gaganyaan mission profile: 3 crew members, ~400 km LEO orbit, up to 7 days, Bay of Bengal splashdown.
- Human Space Flight Centre (HSFC): dedicated ISRO centre established in 2019 to manage the Gaganyaan programme.
- Astronaut crew: 4 Indian Air Force officers (short-listed); final crew yet to be formally announced for the crewed mission.
- Vyommitra: ISRO's female humanoid robot that flew on the uncrewed test mission to simulate human responses in space.
- Budget: ₹9,023 crore approved by the Union Cabinet in 2018; subsequent revisions account for project extensions.
- India aims to establish a space station by 2035 and achieve a crewed lunar mission by 2040 — making long-duration space medicine expertise foundational.
Connection to this news: The AIIMS-ISRO MoU directly addresses the medical readiness gap for Gaganyaan. Without robust space medicine protocols developed and tested by Indian institutions, India would remain dependent on foreign expertise — undermining the programme's strategic autonomy.
India's Space Sector Institutions and Collaboration Framework
ISRO operates under the Department of Space (DoS), directly under the Prime Minister's Office. The Indian National Space Promotion and Authorisation Centre (IN-SPACe) was established in 2020 to regulate and promote private sector participation in space. The Indian Space Policy 2023 further liberalised the sector, permitting private companies to build and launch satellites, rockets, and develop ground systems. Inter-institutional collaboration — such as AIIMS-ISRO — reflects a broader government push to build a comprehensive national space ecosystem that integrates defence, science, medicine, and industry.
- ISRO's Human Space Flight Centre (HSFC): Bengaluru — dedicated to Gaganyaan and future crewed missions.
- IN-SPACe: regulatory body for private space sector activity under the Space Policy 2023.
- ISRO previously signed a space medicine MoU with Sree Chitra Tirunal Institute for Medical Sciences and Technology (SCTIMST), Thiruvananthapuram.
- The AIIMS-ISRO partnership expands this medical research network to India's premier tertiary care and research hospital.
- Spaceflight medicine research will inform protocols for future Indian Space Station crew health management.
Connection to this news: This MoU is part of a deliberate strategy to build India's institutional capacity in space medicine ahead of Gaganyaan's crewed flight, ensuring that health monitoring, emergency medical protocols, and post-flight rehabilitation are designed and delivered by Indian experts.
