Space Docking Experiment (SpaDeX)

India successfully docked two satellites in space, becoming the fourth country to achieve this feat.

• The mission, called Space Docking Experiment (SpaDeX), was conducted by ISRO.
• The satellites, weighing 220 kg each, were launched on December 30, 2024, and docked on January 16, 2025.
• This docking was done with high precision, demonstrating India’s growing space capabilities.
• The mission’s goal was to showcase autonomous rendezvous and docking for future satellite servicing and space station operations.
• The docking process brought the satellites within 3 meters of each other, allowing them to function as a single unit.
• This achievement enables India to join the S., Russia, and China in the group of nations capable of in-space satellite docking.
