Shubhanshu Shukla Completes Seven ISS Experiments

Indian astronaut Group Captain Shubhanshu Shukla has successfully completed all seven microgravity experiments assigned to him aboard the International Space Station (ISS) as part of the Axiom‑4 mission. The announcement came shortly after the crew undocked from the ISS on July 14, marking a significant achievement for Indian space science.

What Was Studied?

The experiments covered diverse areas of biological and physical research. Shukla conducted tests involving tardigrades, cyanobacteria, microalgae, muscle cell growth, and the sprouting of common Indian seeds like methi (fenugreek) and moong (green gram) in microgravity. He also carried out a human-computer interaction study using a module known as the Voyager Display.

These experiments were developed by Indian research teams and supported by ISRO. The insights gathered are expected to contribute directly to India’s Gaganyaan programme, which aims to send humans into low-Earth orbit in the coming years.

Shukla’s Message from Orbit

During a farewell ceremony aboard the ISS, Shukla thanked the ground teams and his fellow astronauts. He called the mission a symbol of a “confident, fearless and aspirational India.” His words resonated with India’s growing ambitions in space exploration and scientific research.

Return to Earth

The Crew Dragon “Grace” spacecraft undocked from the ISS at 4:35 PM IST on July 14. Shukla and his three crewmates are expected to splash down off the California coast around 3 PM IST on July 15. After landing, they will undergo a routine period of medical recovery and rehabilitation.

Over 18 days in space, Shukla participated in more than 60 experiments, seven of which were specifically designed by Indian teams. His performance marks a historic moment as India deepens its engagement with global space missions.
