ISRO achieves another milestone with satellite docking technology

India's space agency, ISRO, has achieved a significant milestone by successfully completing the docking of twin satellites in space, marking its entry into an elite group of nations with such capability. The Space Docking Experiment (SpaDeX) involved the Chaser Satellite (SDX01) and Target Satellite (SDX02), each weighing 220 kg. These satellites were launched on December 30 aboard the PSLV-C60 rocket.

This achievement positions India as the fourth country to master docking and undocking technology, a critical step toward its long-term goal of establishing a space station by 2035. Docking technology plays a pivotal role in connecting spacecraft to space stations, enabling the transfer of astronauts and cargo. It is also essential for missions like Gaganyaan, India’s ambitious manned space program.

The docking system demonstrated in the SpaDeX experiment will aid in future lunar missions, such as Chandrayaan-4. This mission involves bringing lunar surface samples back to Earth, requiring multiple modules to dock in Earth and lunar orbits.

Additionally, the docking capability can extend satellite life through on-orbit repairs, refueling, and modernization. Such advancements highlight ISRO’s growing expertise and ambition in the space sector, reinforcing its global stature.

With Chandrayaan-4 in development and the Gaganyaan mission on the horizon, India’s space journey continues to break new ground, showcasing its readiness for complex, high-stakes operations in outer space.
