In a significant leap for India’s space ambitions, an Indian-made rocket successfully blasted off from the Satish Dhawan Space Centre in Andhra Pradesh, carrying two satellites designed to test space docking technology. The mission, dubbed Space Docking Experiment (SpaDeX), was launched aboard the PSLV-C60 rocket, one of the most trusted launch vehicles in the Indian Space Research Organisation’s (ISRO) fleet.
The launch took place at 16:30 GMT on Monday, and within 15 minutes of liftoff, the mission director confirmed that the rocket had reached an altitude of 470 km (292 miles). The mission was deemed successful, with the PSLV-C60 rocket accurately placing the satellites into a 470 km circular orbit, as announced by ISRO’s chief, Sreedhara Somanath, who described the launch as a “successful accomplishment” and stated that the satellites were placed in the “right orbit.”
This mission is considered crucial for the future of India’s space program, as it involves the testing of in-space docking technology, which is essential for a wide range of space operations, including satellite servicing, payload operations, and the operation of a future space station. Docking technology is particularly important for India’s plans to conduct long-duration human missions and explore options for its own space station.
The SpaDeX mission deployed two small spacecraft, each weighing about 220 kg (485 pounds), into orbit. These satellites are designed to demonstrate several advanced capabilities, including the docking of spacecraft in orbit, a feat that has been achieved by only a few countries so far. The technology tested in this mission is expected to lay the foundation for future missions that require precise and controlled docking procedures.

One of the most notable aspects of this mission is the power transfer between docked spacecraft. This is a critical capability for a variety of space missions, including in-space robotics, composite spacecraft control, and payload operations following undocking. The technology could eventually be used for servicing satellites, refueling spacecraft, and ensuring efficient mission execution for deep space exploration.
In addition to the docking demonstration, each of the two satellites carries advanced payloads, such as an imaging system and a radiation-monitoring device. These devices are designed to measure electron and proton radiation levels in space, which is vital for understanding the space environment and preparing for future human spaceflight missions. Radiation monitoring is an essential component of space exploration, particularly as India prepares for more complex missions, including crewed spaceflights to the Moon and beyond.
India’s successful docking experiment marks its entry into a select group of countries—Russia, the United States, and China—that possess the advanced technology required for space docking. With this achievement, India has taken a significant step toward meeting its ambitious space goals. This success comes as India sets its sights on sending an astronaut to the Moon by 2040, as announced by Prime Minister Narendra Modi. The successful testing of space docking technology will play a crucial role in achieving these objectives, particularly for supporting long-duration missions and building a sustainable human presence in space.
The SpaDeX mission also supports India’s long-term vision of a space station, as docking technology is fundamental for managing complex missions that involve multiple spacecraft. In addition to its practical uses, this mission also enhances India’s standing in the competitive global space arena.
India’s space ambitions continue to grow, and with every successful mission like SpaDeX, ISRO moves closer to its goal of becoming a major player in space exploration.
