Isro postpones SpaDeX docking: Here's the reason behind it

SpaDeX: The initial docking attempt was scheduled for January 6 but was pushed back to January 9 due to the need for further ground simulations to validate the docking process.

In Short

• SDX01 (Chaser) and SDX02 (Target) remain operational
• The SpaDeX mission was launched on December 30, 2024
• It aims to demonstrate India's capabilities in automated space docking

The Indian Space Research Organisation (Isro) postponed the docking of its Space Docking Experiment (SpaDeX) satellites for the second time late on Wednesday night.

Docking in space involves precise alignment and connection of two spacecraft travelling at high speeds in orbit. The process requires meticulous planning and execution, as any misalignment can lead to failure or even collisions.

The delay was announced after the agency detected that during a manoeuvre to bring the two satellites closer — targeting a distance of 225 meters — the drift exceeded expected levels following a non-visibility period when the satellites could not be tracked.

In a statement, Isro explained, “While making a manoeuvre to reach 225 m between satellites, the drift was found to be more than expected, post non-visibility period. The planned docking for tomorrow is postponed. Satellites are safe.”

This indicates that the satellites, designated SDX01 (Chaser) and SDX02 (Target), remain operational despite the drift issue.

The SpaDeX mission, launched on December 30, 2024, aims to demonstrate India's capabilities in automated space docking technology—a complex procedure that only a few countries have successfully mastered.

The initial docking attempt was scheduled for January 6 but was pushed back to January 9 due to the need for further ground simulations to validate the docking process.

The upcoming attempt will be crucial for ISRO as it seeks to join the ranks of nations capable of performing such advanced space operations.

As Isro continues to refine its approach and address the challenges posed by satellite drift, it remains committed to advancing India's space exploration capabilities and achieving successful docking in future missions.

Isro is yet to announce a new date for docking.
