The Indian Space Research Organisation (ISRO) successfully completed the undocking of two satellites under the Space Docking Experiment (SpaDeX) mission. SpaDeX is a cost-effective technology demonstrator for in-space docking using two small spacecraft launched by PSLV. The mission aims to develop and demonstrate rendezvous, docking, and undocking of two small spacecraft, SDX01 (Chaser) and SDX02 (Target), in low-Earth orbit. On March 13, 2025, ISRO successfully undocked the satellites in a 460 km circular orbit with 45-degree inclination. The satellites are now orbiting independently and are in normal condition. This marks ISRO’s successful demonstration of all capabilities for rendezvous, docking, and undocking in a circular orbit.
