**Bengaluru, India** – The Indian Space Research Organisation (ISRO) is on the verge of a groundbreaking achievement in space technology. On December 30th, ISRO will attempt to dock two satellites in orbit – a feat only accomplished by Russia, the US, and China. This ambitious “SpaDeX” (Space Docking Experiment) mission represents a significant leap forward for India’s space program.

The mission involves two 220kg satellites, launched by a PSLV rocket, performing a docking and undocking maneuver at an altitude of 470 kilometers. Traveling at a velocity of approximately 28,800 kilometers per hour – ten times the speed of a bullet – the satellites will utilize ISRO’s domestically developed “Bhartiya Docking System” (BDS) to slow their relative speed to near zero and successfully mate. The BDS, which has received a patent, is designed to meet International Docking System Standard (IDSS) requirements but with significant advancements, including a reduction in the number of motors from 24 (in the IDSS) to just two.

This complex maneuver, described as a “Herculean challenge” by ISRO Chairman Dr. S Somanath, is crucial for India’s future space ambitions. Successful space docking is a prerequisite for missions such as Chandrayaan-4, the construction of the Bharatiya Antariksh Station (BAS), and sending an Indian to the moon.

The project showcases a collaborative effort between ISRO and the private sector. While ISRO conceived and designed the SpaDeX mission, the final assembly, integration, and testing were carried out by Ananth Technologies, a Bengaluru-based space technology company. This public-private partnership has been lauded as a success, demonstrating the capabilities of Indian private space companies.

The successful completion of the SpaDeX mission would solidify India’s position as the fourth nation to master this complex space technology, paving the way for more ambitious and complex space endeavors in the future. The docking experiment is expected to be completed early in the New Year.
