What Happened
- AIIMS New Delhi and ISRO signed a Memorandum of Understanding on March 9, 2026 to advance research in space medicine, with direct relevance to the Gaganyaan human spaceflight programme.
- The MoU was signed by M. Srinivas, Director of AIIMS New Delhi, and Dinesh Kumar Singh, Director of ISRO's Human Space Flight Centre (HSFC).
- Research focus areas include human physiology in microgravity, behavioural health, immunology, gut microbiome research, neuroscience, nutrition, metabolic health, and musculoskeletal degeneration.
- The partnership aims to develop ground-based research analogues (such as bed-rest studies simulating microgravity effects) to prepare and certify India's four Gaganyaan astronaut candidates.
- The collaboration is also oriented toward long-duration missions including India's planned participation in lunar exploration.

Gaganyaan Programme — India's First Human Spaceflight
Gaganyaan is India's national human spaceflight programme managed by ISRO through its Human Space Flight Centre (HSFC), headquartered in Bengaluru. The programme aims to demonstrate India's capability to launch a crewed spacecraft to low Earth orbit (LEO, approximately 400 km altitude) and safely recover the crew. Four astronaut candidates — all IAF (Indian Air Force) test pilots — have been selected and underwent training in Russia at the Gagarin Cosmonaut Training Centre (GCTC) in Yuri Gagarin Cosmonautics Training Centre. India will become the fourth country to independently send humans to space (after the USSR/Russia, USA, and China) upon Gaganyaan's successful crewed mission.
- Gaganyaan launch vehicle: HLVM3 (Human-rated LVM3, formerly GSLV Mk III) — India's most powerful rocket; payload to LEO: 10 tonnes.
- Uncrewed missions: G1 (2023), TV-D1 (Test Vehicle Demonstration, late 2024) — abort system tests completed.
- Crewed flight: Targeted for 2026 (first quarter originally planned); schedule under review.
- Astronaut candidates: Four IAF test pilots; all of Group Captain rank.
- Mission duration: Approximately 3 days in LEO.
- ISRO HSFC (Human Space Flight Centre): Set up in 2019 specifically to manage Gaganyaan.

Space Medicine — Physiological Challenges of Spaceflight
Space medicine is the branch of medicine that studies the physiological and psychological effects of the space environment on the human body. The primary challenges are: (1) Microgravity — causes bone density loss (1-2% per month), muscle atrophy, cardiovascular deconditioning, fluid shift (headward), and vision changes (spaceflight-associated neuro-ocular syndrome, SANS); (2) Radiation — cosmic rays and solar particle events increase cancer risk; (3) Psychological isolation and confinement; (4) Altered circadian rhythms. Short missions (3 days) pose lower risks than long-duration ones; however, even short missions require pre-flight health certification and post-flight rehabilitation. AIIMS's role in developing ground analogues (like bed-rest studies that simulate microgravity effects) will help ISRO understand and mitigate these risks before the actual Gaganyaan mission.
- Bone density loss in microgravity: 1-2% per month (equivalent to years of osteoporosis in months).
- Countermeasures: Resistance exercise, dietary supplements (Vitamin D, calcium), bone-density monitoring.
- SANS (Spaceflight-Associated Neuro-Ocular Syndrome): Affects ~40-70% of long-duration astronauts; causes vision deterioration from intracranial pressure changes.
- Gut microbiome: Evidence suggests space travel alters gut bacterial composition, affecting immunity and metabolism.
- Rehabilitation post-flight: Typically 1-3 months for full musculoskeletal recovery after long missions; 3-day Gaganyaan mission will require shorter but standardised protocols.
Connection to this news: AIIMS's expertise in physiology, occupational medicine, and aerospace medicine is directly applicable to developing the certification and rehabilitation protocols needed for Gaganyaan's crewed phase.
International Space Medicine Collaboration — Context and India's Aspiration
Space medicine has been a specialised field primarily developed by NASA (USA), Roscosmos (Russia), and ESA (Europe) through decades of ISS operations. India's entry into human spaceflight through Gaganyaan requires building an indigenous space medicine capacity to reduce dependence on foreign expertise and to support India's more ambitious long-term goals — including potential participation in the Lunar Gateway and the Artemis programme, and future India-led space station plans. The ISRO-AIIMS MoU is modelled on similar arrangements between NASA and its medical research partners (such as Mayo Clinic and Johns Hopkins) and ESA with European medical universities.
- ISRO's long-term human spaceflight roadmap: Gaganyaan (LEO, 2026-27) → Indian Space Station (2030s) → Lunar exploration.
- India-USA Space Cooperation: 2023 NSAM-ISRO Artemis Accords signatory; potential joint lunar exploration.
- AIIMS New Delhi is the premier medical research institution in India; it conducts altitude physiology research relevant to aerospace medicine.
- Space medicine training for astronaut candidates: Currently provided by GCTC (Russia) and Institut de médecine et de physiologie spatiales (MEDES) in France; AIIMS will provide complementary Indian-context research.
Connection to this news: The MoU represents a foundational step toward India building an indigenous space medicine ecosystem, positioning AIIMS as the national nodal institution for astronaut health research comparable to NASA's Johnson Space Center medical division.
