Indian Astronaut Completes Microgravity Experiments on International Space Station
Indian astronaut Group Captain Shubhanshu Shukla has successfully completed all seven assigned microgravity experiments during his 18-day mission aboard the International Space Station (ISS). ISRO announced that the experiments, which included studies on tardigrades, myogenesis, and sprouting seeds, were all completed as planned. Shukla and the Axiom-4 mission crew have begun their return journey to Earth, marking a significant milestone for India's human spaceflight program and contributions to space-based scientific research.
Unpacked:
Shubhanshu Shukla’s mission makes him the first ISRO astronaut to visit the ISS and only the second Indian to travel to space, after Rakesh Sharma in 1984. This mission marks a major step for India’s human spaceflight ambitions, demonstrating the country’s capability to participate in international missions and contribute to space science research.
Shukla’s experiments included studies on tardigrades (micro-animals known for their resilience), myogenesis (muscle development), and sprouting seeds. These experiments, conducted in microgravity, help scientists better understand biological processes and adaptation to space environments, which is crucial for long-duration missions.
Shukla was shortlisted in 2019 by ISRO’s Institute of Aerospace Medicine and was one of four selected for astronaut training. He underwent basic training in Russia at the Yuri Gagarin Cosmonaut Training Center, followed by mission-specific training at ISRO’s facility in Bangalore, and earned a master’s degree in aerospace engineering.
The Axiom-4 mission is a privately organized international mission involving collaboration between ISRO, NASA, and Axiom Space. Shukla’s participation showcases India’s ability to integrate with global space efforts, reflecting India’s growing stature and expertise in human spaceflight and international scientific collaboration.
