One of ISRO’s standout achievements in 2025 was its participation in the Axiom Mission 4 (Ax-04), a collaborative effort with NASA. On June 25, 2025, Indian astronaut Group Captain Shubhanshu Shukla, serving as the Ax-04 Mission Pilot, successfully launched aboard SpaceX’s Dragon Crew Module to the International Space Station (ISS). The 18-day mission, costing ISRO ₹550 crore, included seven Indian-designed microgravity experiments in life sciences, advancing research for the Gaganyaan mission and India’s long-term space goals, including a planned Moon landing by 2040. The mission marked a historic milestone, with Shukla becoming the first Indian to visit the ISS, boosting national pride and ISRO’s global stature.
Chandrayaan-3: Scientific Breakthroughs
The Chandrayaan-3 mission, which achieved the first soft landing near the Moon’s south pole on August 23, 2023, continues to yield significant scientific insights in 2025. The mission’s Alpha Particle X-ray Spectrometer (APXS) revealed primitive mantle material through volatile measurements in the lunar south polar region, enhancing our understanding of the Moon’s geological composition. Additionally, ISRO confirmed that the Vikram lander and Pragyan rover landed within a buried lunar crater, a discovery announced in 2025, contributing to global lunar research.
SpaDeX Mission
On January 16, 2025, ISRO successfully completed the Space Docking Experiment (SpaDeX), making India the fourth nation after the United States, Russia, and China to demonstrate space docking technology. Launched aboard a Polar Satellite Launch Vehicle (PSLV), the mission showcased ISRO’s capability to develop critical technologies for future space stations and crewed missions, aligning with India’s ambition to establish the Bharatiya Antariksh Station (BIS) by 2035.
NASA-ISRO Synthetic Aperture Radar (NISAR) Mission
The NISAR mission, a joint Earth-observing project with NASA, was launched on July 30, 2025, using a Geosynchronous Satellite Launch Vehicle (GSLV-F16) from Sriharikota. The mission, a decade-long collaboration, employs advanced radar imaging to monitor land surface changes, focusing on ecosystems, crustal deformation, and cryospheric sciences. The GSLV Second Stage (GS2) was flagged off to Sriharikota earlier in 2025, and the mission’s precision launch was lauded by ISRO Chairman Dr. V. Narayanan as one of the most accurate in the world. NISAR’s high-resolution data, capable of detecting changes as small as one centimeter, promises to enhance disaster management and climate research.
PSLV-C59/PROBA-3 Mission
The PSLV-C59/PROBA-3 mission, executed in 2025, successfully deployed the European Space Agency’s (ESA) PROBA-3 satellites into their designated orbit. This mission underscored ISRO’s reliability as a global launch service provider, with the Polar Satellite Launch Vehicle (PSLV) continuing to be a favored carrier for international satellites due to its cost-efficiency and precision.
