India's space agency has successfully launched its first space docking mission, marking a major step towards becoming the fourth country to achieve this technological feat.

The mission, dubbed Space Docking Experiment (SpaDeX), lifted off from the Satish Dhawan Space Centre in Andhra Pradesh at 16:30 GMT aboard ISRO's reliable PSLV rocket. After approximately 15 minutes of flight, the mission director announced a successful launch as the spacecraft reached an altitude of about 470 kilometers (292 miles) [CNN].

This pivotal mission aims to facilitate future endeavors, such as satellite servicing and the operation of India’s planned space station, by employing essential in-space docking technology. Such technology is particularly crucial for missions requiring multiple rocket launches to execute shared objectives.

The launch involved the deployment of two smaller spacecraft, each weighing around 220 kilograms, into a circular orbit at 470 kilometers. It will also demonstrate the capability for power transfer between docked spacecraft, a vital skill for in-space robotics and post-undocking payload operations [Al Jazeera].

The satellites are equipped with advanced payloads, including an imaging system and a radiation-monitoring device that measures radiation levels, catering to the needs of future human spaceflight missions. ISRO Chairman S. Somanath noted that testing of the docking technology is slated to commence in about a week's time, targeting January 7 for further evaluations [Reuters].

A successful demonstration would position India alongside global powerhouses such as the United States, Russia, and China in achieving this capability. Significantly, the integration and testing of the rocket and satellites took place at a private firm, Ananth Technologies, rather than a government agency, marking a first for India [CNN].

This technological advancement not only affirms India's position in the global space sector but also opens the market for ISRO to collaborate on international missions requiring docking facilities and assembly in space. ISRO has converted the usual PSML debris stage into an active, un-crewed orbital laboratory, promoting experimentation and innovation among Indian startups and research institutions.

According to Jitendra Singh, India's science and technology minister, this mission is crucial for the nation's future space ambitions, aligning with Prime Minister Narendra Modi's plans for human space exploration by 2040.
