India’s space agency ISRO achieved a significant milestone in its Space Docking Experiment (Spadex) on Sunday by bringing two satellites within three meters of each other in orbit. Named SDX01 (Chaser) and SDX02 (Target), the satellites captured detailed images and videos of each other during the maneuver. Post-testing, the satellites were repositioned to a safe distance, with the docking process to be completed after thorough data analysis.
Launch and Progress of the Spadex Mission
On December 30, ISRO launched the Spadex mission using the PSLV C60 rocket. Within 15 minutes of flight, the two 220-kg satellites were successfully placed into a 475-km-high orbit. Upon successful docking, India will join the elite group of nations—USA, Russia, and China—that have mastered this complex space technology.
A Leap Towards Future Space Missions
Successful completion of the docking process will prepare India for future missions, including its planned Indian Space Station and human exploration of the Moon. This achievement will position ISRO among the pioneers in advanced space exploration technologies.
