Indian Space Agency ISRO Conducts Trial for Satellite Docking Experiment

The Indian Space Research Organisation (ISRO) has conducted a trial for its Space Docking Experiment (SpaDeX), bringing two satellites within three meters of each other in space. The satellites, named SDX01 (Chaser) and SDX02 (Target), were launched on December 30 aboard a PSLV C60 rocket and placed in a 475-kilometer circular orbit.

According to ISRO, the satellites were maneuvered at a speed of 10 millimeters per second during the trial, which aimed to bring them initially to a distance of 15 meters and then closer to three meters. Following this trial, the satellites were moved back to a safe distance for further analysis of the collected data.

The docking process, which involves the two satellites being controlled as a single spacecraft, will test the functionality of the Bhartiya Docking System, an indigenously developed technology. This technology will also allow for the transfer of electrical power between the satellites to verify the success of the docking operation. The mission's success will be confirmed once the satellites undock and resume independent operations.

The SpaDeX mission is a preparatory step for future Indian space endeavors, including the proposed Bharatiya Antariksh Station and other advanced missions. The docking attempt, which has been postponed twice, involves precise calibration of sensors and extensive ground testing of algorithms and scenarios, ISRO stated.

The docking, once completed, would position India as the fourth nation to achieve this capability, enhancing the country's expertise in autonomous space operations.
