Shukla, who was selected as India’s Axiom astronaut from a pool of four Gaganyaan candidates, launched aboard a SpaceX Dragon spacecraft from NASA’s Kennedy Space Center and docked with the ISS for an extended mission that included scientific experiments, technology demonstrations, and training activities. His 14-day stay — the longest by any Indian national in orbit — surpasses Rakesh Sharma’s pioneering 1984 mission aboard the Soviet Salyut 7 station, which lasted approximately 8 days.

The Mission Profile

Axiom Mission 4, the fourth private astronaut mission to the ISS organised by Houston-based Axiom Space, carried a crew of four — including Shukla as a mission specialist representing India. The mission objectives were dual-purpose: advancing Axiom’s commercial space station programme while providing ISRO with invaluable experience in human spaceflight operations.

During his 14 days aboard the ISS, Shukla conducted a packed schedule of activities. He performed over 20 scientific experiments across disciplines including fluid physics in microgravity, plant growth in space, and the effects of radiation on biological samples. Several experiments were designed specifically by Indian research institutions, including IIT Madras and the Physical Research Laboratory in Ahmedabad, focusing on areas relevant to India’s future space missions.

Shukla also underwent extensive training in EVA (Extra-Vehicular Activity) procedures, life support system management, and emergency protocols — skills that will be directly transferable to the Gaganyaan programme. ISRO Chairman S. Somanath said the mission provided “irreplaceable hands-on experience that no amount of ground simulation can replicate.”

India’s Space Ambitions

The Axiom-4 mission is intimately linked to India’s broader space ambitions. The Gaganyaan programme, India’s first indigenous human spaceflight mission, aims to send Indian astronauts into low Earth orbit aboard an Indian-made spacecraft launched by an Indian rocket. The programme, which has faced several delays since its announcement by Prime Minister Modi in 2018, is now targeted for its first crewed flight in 2027.

Shukla’s experience aboard the ISS provides critical inputs for Gaganyaan’s mission design. Every aspect of his stay — from the physiological effects of microgravity to the psychological challenges of living in a confined space for two weeks — will inform ISRO’s planning for its own crewed missions. The data collected during the mission will help Indian engineers design better life support systems, exercise regimes, and food protocols for Gaganyaan astronauts.

“Subhanshu is not just an astronaut — he is a bridge between international experience and Indian capability,” said ISRO Chairman Somanath. “What he brings back from the ISS will be instrumental in making Gaganyaan safe and successful.”

Scientific Achievements

Among the scientific highlights of Shukla’s ISS stay were experiments in protein crystallisation in microgravity — which could lead to advances in drug design for diseases prevalent in India — and the testing of an ISRO-developed water purification system designed for use in the Gaganyaan capsule. The water purification experiment, which uses a novel membrane technology developed at IIT Delhi, successfully demonstrated that the system can recycle water with over 95% efficiency in microgravity conditions.

Shukla also participated in Earth observation activities, capturing high-resolution images of the Indian subcontinent from the ISS’s Cupola observation module. The images, which included views of the Himalayas, the Ganges delta, and India’s coastline, were shared on ISRO’s social media platforms and generated widespread public engagement. In a nod to Rakesh Sharma’s famous “Saare jahan se achha” response when asked how India looked from space, Shukla described the view as “humbling and magnificent — our planet knows no borders.”

The ISRO-NASA Partnership

The Ax-4 mission underscores the deepening space cooperation between India and the United States. The two countries signed the Artemis Accords in 2023, and India has expressed interest in contributing to NASA’s lunar exploration programme. The ISS mission provides a practical foundation for future collaboration, including potential Indian participation in the Lunar Gateway station and joint Mars exploration initiatives.

For ISRO, which has earned global recognition through cost-effective missions like Chandrayaan and Mangalyaan, the human spaceflight domain represents the next frontier. The Axiom-4 mission demonstrates that India is not just a player in robotic space exploration but is building the capability for sustained human presence in space.

A National Moment

Back on Earth, Shukla’s mission has captured the imagination of the Indian public. Schools, colleges, and science institutions organised live viewing events for his launch and docking. Prime Minister Modi spoke with Shukla via video link during the mission, congratulating him and the ISRO team. The Prime Minister described the mission as “a proud moment for 140 crore Indians and a stepping stone toward India’s destiny among the stars.”

A SpaceX Falcon 9 rocket carrying the company’s Dragon spacecraft lifted off at 6:05 p.m. EDT on Friday, 15 May 2026, from Space Launch Complex 40 at Cape Canaveral Space Force Station in Florida. The launch marked the 34th commercial resupply services mission to the International Space Station (ISS) under SpaceX’s contract with NASA, delivering approximately 6,500 pounds of scientific investigations, supplies, and equipment to the orbiting laboratory.

The Dragon spacecraft autonomously docked at the forward port of the station’s Harmony module at approximately 7 a.m. on Sunday, 17 May, where it was welcomed by the Expedition 74 crew. The successful docking added to SpaceX’s remarkable record of reliability in servicing the space station, a partnership that has become the backbone of NASA’s cargo delivery system to low Earth orbit.

Groundbreaking Scientific Experiments Aboard

The CRS-34 mission carried several new experiments that push the boundaries of space science and have direct implications for life on Earth. Among the most notable is a project designed to determine how well Earth-based simulators mimic actual microgravity conditions. This research is critical for the reliability of ground-based space training and testing facilities, which are used extensively to prepare astronauts and validate equipment before launch.

If the study reveals significant differences between simulated and real microgravity, it could lead to improvements in how scientists and engineers prepare for space missions, potentially saving lives and reducing costly in-orbit troubleshooting. The experiment involves comparing specific physical and biological processes in real microgravity aboard the ISS with identical processes conducted in ground-based simulation facilities.

Wood-Based Bone Scaffolds: A Potential Osteoporosis Breakthrough

One of the most promising experiments aboard CRS-34 involves a bone scaffold made from wood that could produce new treatments for osteoporosis and other fragile bone conditions. The scaffold, developed by researchers studying how natural wood structures can be repurposed for medical applications, is designed to provide a framework on which new bone tissue can grow.

In microgravity, bone loss occurs at an accelerated rate, making the ISS an ideal laboratory for studying bone degradation and testing potential treatments. Astronauts lose approximately 1 to 2 per cent of their bone density per month in space, a rate far exceeding the typical bone loss experienced by osteoporosis patients on Earth. By testing the wood-derived scaffold in this environment, researchers hope to evaluate its effectiveness under the most challenging conditions possible.

If successful, the technology could lead to affordable, biocompatible implants for the millions of people worldwide who suffer from osteoporosis, a condition that causes approximately 9 million fractures annually according to the International Osteoporosis Foundation. The use of wood as a base material is particularly innovative because it is abundant, sustainable, and structurally similar to bone at the microscopic level.

STORIE Mission: Imaging Earth’s Ring Current from Inside

Among the instruments carried by Dragon is equipment for the STORIE mission, which stands for Storm Time O+ Ring Current Imaging Evolution. This NASA mission is designed to provide a unique inside-out view of the ring current, a doughnut-shaped region of charged particles that encircles Earth at altitudes between approximately 10,000 and 60,000 kilometres.

The ring current plays a crucial role in space weather, which affects satellite operations, GPS accuracy, radio communications, and even power grids on Earth’s surface. During geomagnetic storms, the ring current intensifies dramatically, and understanding its behaviour is essential for predicting and mitigating the effects of space weather events.

Previous missions have studied the ring current from outside, looking down at it from higher orbits. STORIE’s unique contribution is its perspective from the ISS, which orbits within the inner edge of the ring current during storm events. This inside-out view will provide unprecedented data on the composition and dynamics of the charged particles, particularly oxygen ions, that drive ring current behaviour.

Blood Cell Research: Understanding Space Anaemia

The CRS-34 cargo also includes equipment to help researchers evaluate how red blood cells and the spleen change in space. This research addresses a well-documented but poorly understood phenomenon known as space anaemia, a condition in which astronauts’ bodies destroy red blood cells at a higher rate than on Earth.

Studies have shown that astronauts destroy approximately 54 per cent more red blood cells per second in space compared to on Earth. While the body compensates to some extent, the elevated destruction rate can lead to anaemia, fatigue, and reduced physical performance, problems that become increasingly serious on longer missions.

Understanding the mechanisms behind space anaemia is critical for planning extended missions to the Moon, Mars, and beyond. If astronauts cannot maintain healthy blood cell levels during multi-year journeys, it could limit the feasibility of deep space exploration. The ISS experiments aim to identify specific factors in the microgravity environment that trigger increased red blood cell destruction, potentially leading to countermeasures that could protect astronauts on future missions.

SpaceX’s Growing Role in Space Infrastructure

The CRS-34 mission underscores SpaceX’s central role in maintaining and supplying the International Space Station. Since the first commercial resupply mission in 2012, SpaceX has established an unmatched track record of reliable cargo delivery. The Dragon spacecraft’s ability to autonomously dock with the station, carry both pressurised and unpressurised cargo, and return experiments safely to Earth makes it an indispensable component of the ISS programme.

Each resupply mission also demonstrates the maturing of commercial space operations. What was once a high-risk experimental venture has become routine, with SpaceX launching and landing Falcon 9 boosters with remarkable consistency. The first stage of the CRS-34 Falcon 9 rocket successfully landed back at Cape Canaveral shortly after launch, ready to be refurbished and reused on a future mission.

Looking Forward: The Future of ISS Research

The experiments aboard CRS-34 represent just a fraction of the research conducted on the International Space Station, which hosts hundreds of experiments at any given time across disciplines ranging from biology and medicine to materials science and Earth observation. As the station enters the final phase of its operational life, expected to extend into the early 2030s, every resupply mission carries added significance as scientists race to maximise the return on one of humanity’s most ambitious and productive scientific investments.
