Thu Jan 16 05:02:52 UTC 2025: ## ISRO Achieves Historic Space Docking, Joining Elite Space Nations

**Bengaluru, January 16, 2025** – The Indian Space Research Organisation (ISRO) has successfully completed its SpaDeX docking experiment, making India the fourth country, after the USA, Russia, and China, to achieve this significant milestone. The docking of two satellites, SDX01 (Chaser) and SDX02 (Target), launched on December 30, 2024, was executed in the early hours of Thursday.

ISRO’s Mission Operations Complex (MOX) at ISTRAC oversaw the complex procedure, culminating in the successful capture and rigidization of the two spacecraft. The agency announced the success via X (formerly Twitter), detailing the steps involved, from initial maneuvering to the final docking and subsequent control of the combined satellites. Future plans include demonstrations of power transfer between the docked satellites and eventual undocking.

The SpaDeX mission is crucial for future ambitious projects, including sending an Indian astronaut to the Moon, lunar sample return missions, and the construction of an Indian Space Station. The successful docking and planned undocking will pave the way for further advancements in in-space robotics, composite spacecraft control, and payload operations. The satellites are expected to operate independently for up to two years after separation.

The experiment, initially scheduled for January 7th, faced several postponements due to unforeseen technical challenges, including a larger than anticipated drift between the satellites. However, ISRO engineers successfully addressed these issues, leading to Thursday’s triumphant outcome. Dr. V. Narayanan, Secretary DOS, Chairman Space Commission and Chairman ISRO, extended his congratulations to the ISRO team. The successful SpaDeX docking marks a substantial leap forward for India’s space program.
