Shubhanshu Shukla's Groundbreaking Journey: Seven Experiments Completed on ISS

A Milestone Achieved in Space Research
New Delhi: Astronaut Shubhanshu Shukla has marked a significant achievement by completing all seven planned microgravity experiments during the Axiom-4 mission, as reported by ISRO on Monday.
The experiments included studies on the Indian strain of Tardigrades, Myogenesis, the sprouting of methi and moong seeds, Cyanobacteria, Microalgae, crop seeds, and the Voyager Display.
On July 13, 2025, the Expedition 73 crew aboard the International Space Station (ISS) participated in a farewell ceremony for the Axiom-4 crew, which included ISRO's Gaganyatri.
During the farewell, Shukla expressed gratitude to the Expedition 73 members for their assistance and acknowledged ISRO's efforts in developing a scientific research portfolio and outreach activities involving national participation.
Shukla, along with three other astronauts from the Axiom-4 mission, commenced their journey back to Earth on Monday as the Dragon Grace spacecraft undocked from the ISS after an 18-day mission.
Following a series of orbital maneuvers post-undocking, the Dragon spacecraft is anticipated to splash down off the California coast on Tuesday at 3:01 PM IST.
Anil Prakash, Director General of the Satcom Industry Association-India, emphasized that Shukla's 18-day mission is not merely a milestone but signifies India's advancement into the space-biotech sector.
He noted that this mission, facilitated by strategic collaboration with the private sector, exemplifies a robust public-private partnership that is transforming space research into sustainable biotech innovations.
Prakash commended this collaborative achievement, which positions India as a leader in global space-driven biotech.
Throughout his time at the ISS, Shukla engaged with Prime Minister Narendra Modi, interacted with school students, and connected with ISRO centers via amateur radio.
