India’s Historic Return to Human Spaceflight: Shubhanshu Shukla’s Journey to the ISS -

In a momentous event for Indian space exploration, the Indian Space Research Organisation (ISRO) is witnessing one of its most significant achievements in over four decades. Today, Group Captain Shubhanshu Shukla, an Indian Air Force (IAF) test pilot and ISRO astronaut, embarked on the Axiom Mission 4 (Ax‑4) to the International Space Station (ISS). This historic mission marks India’s long-awaited return to human spaceflight after the landmark 1984 flight of Squadron Leader Rakesh Sharma.

A Breakthrough on Multiple Fronts

Shukla’s flight is remarkable on several fronts:

He is the first Indian citizen to journey to the ISS. (Other astronauts of Indian origin, like Kalpana Chawla, have flown, but not under the Indian flag) .
He becomes the second Indian in space, following Rakesh Sharma’s 1984 Soviet Soyuz flight.
The mission also introduces astronauts from Poland and Hungary to the ISS each nation sending its first-ever crew a testament to expanding international collaboration

Commanded by veteran NASA astronaut Peggy Whitson, who holds the record for an American’s cumulative time in space, the four‑member crew of Shukla, Whitson, Poland’s Slawosz Uznanski, and Hungary’s Tibor Kapu is being launched aboard a SpaceX Dragon spacecraft atop a Falcon 9 rocket from NASA’s Kennedy Space Center in Florida

Mission Objectives and Scientific Endeavors

A key mission aim is to bolster India’s upcoming human spaceflight program, Gaganyaan, by providing operational learnings in docking, spaceflight, and station interaction.

Shukla is assigned seven scientific experiments aboard the ISS, spanning microgravity life sciences, materials research, and space agriculture. He will also carry five additional NASA‑partnered payloads, including projects focused on space farming—potentially critical for long-duration missions.

Beyond research, Shukla will interact live with students in India from space, a symbolic gesture aimed at inspiring future generations. These educational outreach activities underscore the mission’s dual focus on science and inspiration.

A Personal Milestone and National Pride

Born in Lucknow in 1985, Shukla’s rise to this moment has been nothing short of remarkable. A graduate of the National Defence Academy (NDA) with a BSc in Computer Science and the Indian Institute of Science (IISc), he has also logged over 2,000 flight hours in fighter jets including Su‑30 MKI, MiG‑21, and Jaguar, eventually rising to the rank of Group Captain in March 2024 .

Anecdotes of his unwavering dedication have surfaced in Indian media. On one occasion, during his sister’s wedding, he reportedly stepped out amid the ceremony to sit for the NDA entrance exam“a quiet act of resolve” that prefigured his eventual ascent to astronaut status. Such stories underscore the perseverance that propelled him toward this historic flight.

Launch Delays and Weather Challenges

Originally scheduled to launch on June 10, 2025, weather conditions along the launch corridor forced a postponement. Initially shifted to June 11, ongoing concerns over high winds and potential rainfall pushed the launch window further to June 11 at 5:30 PM IST, with docking expected to occur approximately 28 hours later. ISRO chairman Dr. V. Narayanan and travel teams have already arrived at Kennedy Space Center to support Shukla. The IAF extended its blessings, calling the mission a “new chapter in the Indian space odyssey”.

Strategic Significance for India’s Space Goals

This mission is far more than a one‑off milestone it represents a strategic stepping stone toward India’s aspirations in human spaceflight and deep-space exploration. Prime Minister Narendra Modi clinched a collaborative framework with NASA during his 2023 Washington visit, opening this pathway. Shukla’s in-space experience will feed directly into ISRO’s domestic Gaganyaan mission, slated for 2027, as well as future lunar and Bharatiya Antariksh Station objectives. While the mission involves commercial partners SpaceX and Axiom Space it remains a government‑sponsored Indian mission, funded in part by contributions of approximately ₹50 crore for Shukla’s training and ISS time .

Global Cooperation and Private‑Sector Involvement

Ax‑4 is the fourth private astronaut mission organized by Axiom Space, building on themes of global cooperation and commercialization of ISS access. The formal partnership between NASA and Axiom allows countries like India, Poland, and Hungary to tap into low‑Earth‑orbit infrastructure democratizing human spaceflight.

Looking Ahead: Docking and Return

Assuming an on‑schedule launch on June 11, the Crew Dragon will dock at ISS approximately 28 hours later likely on June 12 or 13. Shukla and his crew are expected to spend up to 14 days on board, conducting experiments, educational events, and international cooperation projects. The mission will conclude with a return to Earth, offering ISRO invaluable first‑hand experience that strengthens India’s credentials in human spaceflight and paves the way for future endeavors in lunar missions, space stations, and scientific research.
