Answer: ISRO (Indian Space Research Organisation)
Notes: The Indian Space Research Organisation (ISRO) has successfully completed the second docking of its two satellites, SDX01 (Chaser) and SDX02 (Target), under the Space Docking Experiment (SpaDeX) mission. SpaDeX is a technology demonstration mission by ISRO to validate the ability to dock and undock small satellites in low-Earth orbit. The mission used two satellites, each weighing around 220 kg, launched by the Polar Satellite Launch Vehicle-C60 into a 460 km circular orbit. The primary objective of SpaDeX was to develop and demonstrate the capability for spacecraft rendezvous, docking, and undocking. Secondary objectives include testing electric power transfer between docked spacecraft, developing spacecraft control systems, and testing payload operations after undocking for deep-space missions.
