General Science Current Affairs Analysis
The Indian Space Research Organization (ISRO) has successfully completed the undocking of two satellites, part of the Space Docking Experiment (SpaDeX) mission, marking a significant milestone in India's space exploration journey.
SpaDeX mission is a cost-effective technology demonstrator mission for the demonstration of in-space docking using two small spacecraft launched by PSLV.
The primary objective of the SpaDeX mission is to develop and demonstrate the technology needed for rendezvous, docking, and undocking of two small spacecraft in a low-Earth circular orbit.
Secondary objectives include: Demonstration of the transfer of electric power between the docked spacecraft, which is essential for future applications such as in-space robotics,
The SpaDeX mission consists of two small spacecraft (about 220 kg each) launched by PSLV-C60.
ISRO has now accomplished the pivotal operation of undocking of SPADEX satellites in the very first attempt on 13th March, 2025.
The undocking of the satellites took place in 460 km circular orbit with 45-degree inclination.
The satellites are now orbiting independently and their health is normal.
With this, ISRO has now successfully demonstrated all the capabilities required for rendezvous, docking and undocking operations in a circular orbit.
Significance:
iThis accomplishment made India the fourth country after USA, Russia and China in the world to achieve the feat.
