Key Highlights
Indian astronaut Shubhanshu Shukla’s 18-day journey aboard the International Space Station as part of Axiom-4 set new standards for scientific outreach and innovation. From agriculture to cognitive science, his multifaceted experiments are poised to shape future space missions and life on Earth.
Mission Science: Innovation in Microgravity
Conducted over 60 experiments across agriculture, biomedicine, neuroscience, and astronaut health—seven directly commissioned by ISRO.
Pioneered the sprouting of methi (fenugreek) and moong seeds in petri dishes to study germination and early plant development under zero gravity. Seeds were deep-frozen, then will be observed for genetic, microbial, and nutritional changes on Earth, advancing knowledge for sustainable space farming.
Led crop research by growing, photographing, and storing various seed varieties, aimed at developing plant strains resilient to the rigors of space.
Examined microalgae and cyanobacteria's capabilities for food, oxygen production, and spacecraft recycling systems, testing their viability for closed-loop life support on long missions.
Astronauts and Avatars: Screentime, Brains, and Bubbles
Dived into screen time effects with Voyager Display, evaluating cognitive and physical impacts of extended digital display use in microgravity—a first for Indian experiments in this field. This research will inform design and ergonomics of future spacecraft instrumentation.
Broke new ground in brain-computer interface research: together with a crewmate, Shukla conducted the first direct brain-to-computer communication in space through mental calculations, recording focus states detectable by sensors.
Demonstrated water’s unusual behavior in space by creating free-floating bubbles, visually explaining microgravity physics to the public.
Participated in myogenesis and stem cell experiments, analyzing muscle cell behavior and potential enhancements for tissue growth, relevant to managing muscle atrophy in astronauts and contributing to regenerative medicine.
Broader Impacts and Legacy
Supported mental health monitoring initiatives and collaborated on studies examining cancer, diabetes, circulation, and astronaut well-being under spaceflight stressors.
Interacted live with ISRO scientists and students, inspiring India's next generation and strengthening connections between space research communities.
His mission represents the highest volume of research on any Axiom Space private astronaut mission, marking a turning point for Indian and global participation in human spaceflight studies.
Shukla’s achievements not only propel India’s Gaganyaan ambitions but also pioneer knowledge vital for long-duration space travel and sustainable living—on and beyond our planet.
