ISRO’s SpaDeX Mission: Pioneering India’s Future in Space Docking Technology

The Indian Space Research Organization (ISRO) is set to resume experiments on the SpaDeX (Space Docking Experiment) mission in mid-March by attempting to separate and re-dock two satellites, Chaser and Target. This mission, launched on December 30, 2023, deployed the satellites SDX01 and SDX02 to demonstrate space docking technology. After multiple attempts, ISRO successfully docked them on January 16, 2024.

According to ISRO Chairman V Narayanan, the unified satellite remains in an elliptical orbit, which provides a 10-15 day experimental window every two months. The next opportunity for these experiments begins on March 15, 2024. ISRO is currently conducting simulation tests for satellite separation and re-docking before commencing actual operations.

A key goal of the SpaDeX mission is to master docking and undocking technologies, which are crucial for future projects like Chandrayaan-4 and the construction of Bharat Antariksha Station, India’s proposed space station. Following successful docking and rigidization, ISRO aims to test electrical power transfer between the satellites before their separation. With ample propellant onboard, additional experiments are planned for the next available slot in two months.

The successful execution of this mission will play a crucial role in advancing India’s space capabilities, particularly in autonomous docking, orbital maneuvering, and in-orbit servicing technologies. These are essential for future space exploration and infrastructure development.

Separately, Union Science and Technology Minister Jitendra Singh inaugurated e-Tractor and e-Tiller developed by CSIR-Central Mechanical Engineering Research Institute, Durgapur. These innovations highlight India's progress in green technology and sustainable agricultural practices.
