Space De-docking Mission

On January 16, 2025, the Indian Space Research Organisation (ISRO) achieved milestone in space exploration by successfully docking two satellites, SDX01 and SDX02. Following this, on January 30, ISRO completed a complex de-docking process. This achievement marks India’s entry into an elite group of countries capable of such advanced space operations.

About Docking and De-docking

Docking involves two spacecraft connecting in space. It requires precise alignment of speed and orientation. De-docking, while seemingly simpler, is equally complex. It requires controlled separation to prevent collisions in microgravity. Minor forces can lead to unintended drift.

The Complexity of De-docking

De-docking is not just about unhooking. It involves careful disengagement of latches and hooks. This process must be executed remotely. The spacecraft may have a pressurised tunnel that needs careful decompression. Precise low-force separation is critical.

Future Missions and Applications

ISRO’s success in docking and de-docking sets the stage for future missions. Key missions include Chandrayaan-4, aimed at lunar sample return, and Gaganyaan, India’s first human spaceflight mission. Mastering docking technology is essential for in-space refuelling. This capability can extend satellite lifespans and reduce the need for new launches.

The SpaDex Mission Overview

The SpaDex mission was launched on December 30, 2024. It involved the two satellites SDX01 and SDX02. The mission aimed to demonstrate space docking technology with small spacecraft. It was launched using a Polar Satellite Launch Vehicle (PSLV).

Future Plans

ISRO plans to conduct further experiments starting March 15, 2025. The unified satellite is currently in an elliptical orbit. This allows for a limited window to conduct experiments every two months.
