The Indian Space Research Organisation (ISRO) has accomplished a significant milestone by successfully docking satellites as part of its pioneering Space Docking Experiment (SpaDeX), sources within the space agency confirmed on Thursday.
"The docking was performed successfully. We will be issuing a statement soon," a source told PTI, highlighting the mission’s success.
Earlier, on January 12, ISRO had conducted a trial manoeuvre, bringing two spacecraft to within three metres of each other before moving them back to a safe distance.
This preparatory step was critical for Thursday’s successful docking operation.
Major technological leap for India
The SpaDeX mission, launched on December 30, 2024, is a cost-effective technology demonstrator aimed at showcasing in-space docking capabilities.
Docking technology is vital for missions requiring multiple rocket launches to achieve unified objectives.
The mission's launch vehicle, the PSLV-C60, carried two small satellites—SDX01 (Chaser) and SDX02 (Target)—along with 24 payloads. The rocket lifted off from the first launchpad at the Satish Dhawan Space Centre in Sriharikota.
About 15 minutes after liftoff, the satellites, each weighing approximately 220 kg, were successfully deployed into a 475-km circular orbit. The operation demonstrated precision and technological prowess, setting a benchmark for future missions.
Enabling advanced space missions
According to ISRO, the SpaDeX mission serves as a foundational step in advancing docking technologies, which are critical for complex space operations such as assembling large structures, refuelling, and interplanetary missions.
The successful docking reinforces India’s position as a key player in space technology, laying the groundwork for more ambitious projects and international collaborations.
