Axiom-4 vs. Soyuz T-11: Check Key Differences Between Shubhanshu Shukla and Rakesh Sharma's Space Missions By KRITI BARUA LAST UPDATED: JUL 15, 2025, 12:27 IST Rakesh Sharma and Shubhnashu Shukla: Axiom-4, launched in 2025, is a commercially arranged mission to the ISS involving global collaboration and advanced microgravity research. It features modern spacecraft like SpaceX's Dragon and includes outreach and commercial activities. In contrast, Soyuz T-11 was a government-led Indo-Soviet mission in 1984 focused on goodwill and scientific exchange. It used Soviet technology and conducted 43 experiments aboard Salyut 7. Axiom-4 marks India's return to spaceflight with broader scientific and diplomatic goals. India's space missions have come a long way—from Rakesh Sharma's flight on Soyuz T-11 in 1984 to Shubhanshu Shukla's journey aboard Axiom-4 in 2025.  Rakesh Sharma became the first Indian in space when he travelled with Soviet astronauts to the Salyut 7 space station. His mission focused on Earth observation and space medicine.  Axiom-4, on the other hand, is a modern, international mission launched by SpaceX's Falcon-9 rocket. It carried Shukla to the International Space Station (ISS), where he conducted experiments in science and technology. The main difference is in the time and technology—Soyuz was a Cold War-era mission with limited tech, while Axiom-4 used advanced systems and was part of a commercial spaceflight programme.  But both missions share one crucial thing: they showed India's growing role in space and inspired generations of scientists and dreamers.
