India launches first space dock mission

India on Monday launched its first space docking mission, carried out on an Indian rocket, to become the fourth country to achieve this advanced technical prowess. The mission that asSpace Docking Experiment (SpaDeX)known, lifted at 16:30 GMTSatish Dhawan Space Centrein the state of Andhra Pradesh, on board the Indian space agency ISRO's “workhorse” rocket PSLV. After about 15 minutes, the mission director gave the green light and declared the launch successful after the spacecraft reached an altitude of about 470 kilometers.

Importance of docking technology for the future

This mission is considered crucial to future space endeavors, including satellite maintenance as well as the operation of the country's planned space station. In-space docking technologies are essential when multiple rocket launches are necessary to achieve common mission objectives.

The mission in detail

The Indian mission will place two small spacecraft, each weighing about 220 kilograms, into a circular orbit at an altitude of 470 km. The transfer of electrical energy between the docked spacecraft will also be demonstrated. This capability is critical for applications such as space robotics, the control of complex spacecraft and the operation of payloads after unhooking.

Technological innovations and experiments

Each satellite is equipped with advanced payloads, including an imaging system and a radiation monitor designed to measure electron and proton radiation levels in space. This data is crucial for future manned space missions. ISRO Chairman S. Somanath noted that the actual testing of the docking technology could take place in about a week, with a target date of around January 7.

India in the international context

A successful demonstration would place India alongside the US, Russia and China as one of the few countries to have developed and tested this capability.

Private collaborations and innovation in the space sector

For the first time in India, the rocket and satellites were manufactured by a private company calledAnanth Technologiesintegrated and tested, rather than at a state institution. According to astrophysicist Somak Raychaudhary of Ashoka University, the unveiling of this technology is not only a step into the ranks of rare countries with this capability, but also opens the market for ISRO to act as a launch partner for various global missions that require docking facilities or in-space assembly.

New approach in the use of the final rocket stage

The fourth stage of PSLV, which typically becomes space debris, has been converted into an active, unmanned laboratory. The final stage of the rocket has been repurposed to become an orbital laboratory and is used for various experiments. "The PSLV Orbital Experiment Module (POEM) is a practical solution from ISRO that offers Indian startups, academic institutions and research organizations the opportunity to test their space technologies without having to launch entire satellites. By making this platform accessible, we lower the barriers to entry and enable a broader set of players to contribute to the space sector," said Pawan Goenka, Chairman, Indian Space Agency.
