Group Captain Shukla Puts India’s Science on the ISS Map with 7 Experiments

As the first Indian astronaut to dock at the International Space Station (ISS), Group Captain Shubhanshu Shukla completed seven fully Indian‑designed experiments as part of the Axiom‑4 mission. This achievement marks a critical milestone in India’s journey toward its Gaganyaan crewed programme.

🚀 Mission Highlights

• Mission Duration & Context
  Shukla spent 18 days aboard the ISS (June 26–July 15, 2025), taking part in over 60 experiments from 31 nations; India contributed seven major ones via ISRO and collaborating institutions.

🔬 Seven Indian‑Designed Experiments

1. Space Microalgae (ICGEB & NIPGR): Deployed and stowed algae strains to study growth in microgravity—potential sources of food, oxygen, and biofuel.

2. Sprouts Project (UAS Dharwad & IIT Dharwad): Germination and early growth of salad seeds (like mung and methi) in space; seeds will be grown for multiple generations on Earth to analyze genetic, microbial, and nutritional changes.

3. Voyager Tardigrade (IISc Bengaluru): Studied survival, revival, reproduction and transcriptomics of extreme-living tardigrades in microgravity.

4. Myogenesis (InStem): Investigated muscle regeneration and supplement effects against skeletal muscle atrophy—relevant to both astronauts and Earth‑based muscle degeneration treatments.

5. Voyager Displays / Cognitive Task Study (IISc Bengaluru): Tested human interaction with electronic displays and cognitive tasks like spatial memory, stress, and well‑being in orbit.

6. Cyanobacteria in Microgravity (ICGEB): Analyzed growth and proteomic response of cyanobacteria under space conditions on different nutrient modes.

7. Food Crop Seeds in Microgravity (IIST & Kerala Agricultural University): Evaluated growth and yield parameters of food crop seeds in microgravity.
