India is on the verge of achieving a major space milestone, as the Indian Space Research Organisation (ISRO) prepares for the first-ever in-orbit docking of its SpaDeX satellites.
The two satellites, SDX01 (Chaser) and SDX02 (Target), were launched on December 30, 2024. Initially, they drifted apart to a distance of about 20 kilometres.
However, after a series of precise maneuvers, the gap between them has now been narrowed to just 600 meters, setting the stage for a historic docking event scheduled for Thursday morning at 8:00 am IST.
The mission marks a significant advancement in India's space technology. With this docking, India will join a select group of countries capable of performing such intricate operations in space.
The successful docking will demonstrate the nation's growing expertise in areas essential for the future of space exploration.

The primary objective of this mission is to showcase advanced technologies critical for future missions, such as lunar explorations and the eventual establishment of India's own space station.
The docking process itself is a complex one, involving sophisticated communication between the two satellites. They are linked by an inter-satellite radio frequency system, which enables them to exchange real-time data on their positions and orientations.
This data is crucial for ensuring a safe and precise docking procedure.
ISRO had initially scheduled the docking for January 6, but the operation was postponed to January 8 to allow for thorough validation checks. The need for these checks underscores the precision required for such a task.
Ensuring the safety and accuracy of the docking process is paramount, as any errors could potentially jeopardise the mission.
As the satellites near their docking point, ISRO's tracking systems are actively monitoring their movements, with assistance from Swiss-based S2A Systems.
These systems play a crucial role in providing real-time data, which helps the team track the satellites' progress and ensures everything is on course for the final docking attempt.
Once the docking is complete, it will mark a new chapter in India's space exploration journey. Not only will this success enhance India's space capabilities, but it will also contribute to global advancements in automated docking systems.
These systems are vital for future interplanetary missions, which may involve docking with spacecraft, landers, or space stations in distant orbits or even on the Moon or Mars.
