Why Shubhanshu Shukla matters so much for India's space tech
Shubhanshu Shukla
has returned to Earth after an 18-day journey aboard the International Space Station (ISS) as part of the
Axiom-4 mission
. But his touchdown will translate into a big takeoff -- India's indigenous human spaceflight programme. Shukla's safe splashdown off the California coast marked more than just the end of a pioneering spaceflight; it symbolized a new chapter for India's ambitions in space exploration. Shukla's mission represents the country's first human presence aboard the
ISS
and serves as a vital stepping stone toward
Gaganyaan
, India's mission to send people into space using its own technology. His experience offers both practical insight and symbolic momentum to a nation on the brink of joining the elite club of spacefaring powers with crewed capabilities.
What Shukla achieved on the Axiom-4 mission
As the pilot of the Axiom-4 mission, Shubhanshu Shukla played a critical role in operating SpaceX's Crew Dragon spacecraft, including its launch, docking, undocking, and re-entry. His position made him the first Indian military pilot to execute real-time operations aboard a commercial spacecraft alongside a veteran like Peggy Whitson. This exposure to both the technical and psychological challenges of space travel was critical for an astronaut preparing for India's future crewed missions.
In orbit, Shukla was actively involved in over 60
scientific experiments
, a significant portion of which were India-led. These included studies on plant growth using Indian staples like moong and methi, analysis of cyanobacteria and microalgae for sustainable
life-support systems
, and experiments involving tardigrades to understand biological resilience in space. Other research explored muscle atrophy, diabetes monitoring, and the physiological effects of prolonged screen exposure in microgravity. These experiments were not abstract exercises. They provide essential insights into the design of life-support and medical systems for long-duration missions, key for India's ambitions in independent space habitation.

Live Events
Strategic impact on
India's space ecosystem
The Axiom-4 mission is far from a standalone achievement. It has directly enhanced India's technical readiness for human spaceflight. Shukla's mission provided ISRO with hands-on feedback on spacecraft systems integration, ground communication protocols, and emergency response procedures, all critical components for the upcoming Gaganyaan mission. The scientific outcomes of his experiments will influence not only mission design but also academic and industrial research within India. From universities to biotech startups, many domestic players were involved in conceptualizing and building the payloads for Axiom-4. This collaborative structure lays the groundwork for a robust space-tech ecosystem within the country.
Equally important is the human resource development angle. Shukla's training regimen, which included simulations, quarantine protocols and rigorous health monitoring, serves as a model for preparing future Indian astronauts. It also underscores the physiological and psychological benchmarks ISRO must meet in its astronaut selection and training processes for Gaganyaan.
Beyond technology and science, Shukla's participation strengthens India's space diplomacy. The Axiom-4 mission, executed in partnership with
NASA
and SpaceX, situates India firmly in global commercial and scientific space efforts. This enhances ISRO's credibility as a partner in multinational missions and opens up avenues for joint research and investment.

Gaganyaan: The next giant leap
India's Gaganyaan programme, for which Shukla and three others have been selected, is designed to send a crew of three astronauts into Low Earth Orbit (LEO) for up to seven days using an indigenously developed launch system and crew module. With its first uncrewed test flights scheduled for 2025 and a human flight targeted for 2027, Gaganyaan will make India the fourth nation -- after the United States, Russia and China -- to independently send humans into space.
Technologically, Gaganyaan represents a significant leap. It requires a human-rated launch vehicle, advanced re-entry systems and life-support mechanisms that India is developing from the ground up. It also demands complex ground infrastructure, ranging from astronaut training facilities to mission control networks capable of handling the nuances of human spaceflight.
But Gaganyaan is more than a technical challenge. It is a strategic national goal that will elevate India's global standing, drive research in advanced materials and bio-sciences, and serve as a catalyst for broader participation in lunar and interplanetary exploration. It also inspires a new generation of scientists and engineers by placing human spaceflight within the nation's grasp.
Why Shukla's mission is a turning point
The importance of Shubhanshu Shukla's participation in Axiom-4 goes far beyond the symbolic. It marks India's entry into the practical realities of living and working in space. His training and mission execution create a reference framework for ISRO as it prepares for human flight. The scientific results he helped gather will refine space medicine, agriculture, and life-support technologies. Economically, the mission -- backed by Rs 550 crore in investment -- has already sparked interest and growth in India's nascent space start-up sector. Strategically, it sends a clear message: India is no longer an emerging participant in human spaceflight but an active contributor shaping its future.
Shubhanshu Shukla's successful journey aboard Axiom-4 marks a significant inflection point in India's space history. It merges symbolic achievement with functional progress, demonstrating both capability and intent. As India moves closer to launching its own astronauts aboard its own spacecraft, Shukla's experience offers a blueprint as well as a boost.

Nisar mission to benefit global community in earth observation: Isro chief
Nisar mission TIRUCHIRAPALLI: The Nisar mission , jointly developed by Isro and the national aeronautics and space administration ( Nasa ), would significantly benefit the global community in earth observation , Isro chairman V Narayanan said here on Saturday. The GSLV-F16/Nisar Mission is the result of over a decade of robust technical cooperation between the two teams of Isro and Nasa-jet propulsion laboratory, US. According to Isro , the mission in itself has got a lot of firsts -- it is the first mission to carry dual-band radar satellite, a GSLV rocket will carry a satellite to be placed in Sunsynchronous Orbit (unlike PSLV rockets) and it is the first Isro-Nasa Earth Observation Mission. Nisar, which is short for Nasa-Isro synthetic aperture radar (Nisar), would help scientists comprehensively monitor Earth's land and ice surfaces, building a detailed record of large and small changes over time. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Jakarta: Unsold Sofas May Be at Bargain Prices (Prices May Surprise You) Sofas | Search Ads Search Now Undo The mission would also be crucial in helping the scientific community to gain a better understanding of the processes involved during natural calamities like earthquakes, volcanic eruptions and landslides. As per the collaboration between Isro and Nasa, the rocket would carry a unique earth observation satellite with a dual-frequency radar provided by Nasa's L-Band and Isro's S-Band. The Radar would use Nasa's 12 metre mesh reflector antenna that has been integrated into ISRO's I3K satellite bus. Speaking to reporters here, Narayanan said, "Nasa-Isro Synthetic Aperture Radar (Nisar) satellite launch will be done using our GSLV-MkII vehicle ( GSLV-F16 ). The payloads are jointly realised by Isro and Jet Propulsion Laboratory (JPL), USA. This satellite is going to be useful for the global community in earth observation and disaster mitigation areas." "The Mission is also a very, very important as Isro would be making the 102nd launch from Indian soil that is targeted on July 30, 5.40 pm (from Sriharikota)", Narayanan also the secretary, department of space, said. Weighing 2,392 kg, the satellite would observe the earth with a swath of 242 km and high spatial resolution, using SweepSAR technology for the first time, Isro said. The satellite would scan the entire globe and provide all weather, day and night data at 12-day interval and enable a wide range of applications. The radar can detect even small changes in the Earth's surface such as ground deformation, ice-sheet movement and vegetation dynamics. Some of the other applications are ship detection, shoreline monitoring, storm characterisation, changes in soil moisture, mapping and monitoring of surface water resources and disaster response, the space agency said. Nisar would provide scientific information about the Earth's processes and it would study key changes in Earth's land and ice. The mission would also be more powerful than previous Synthetic Aperture Radar missions as it will monitor parts of Earth which are not previously covered.
