The Indian Space Research Organization (ISRO) on Wednesday postponed the Space Docking Experiment (Spadex) related to connecting two satellites for the second time. After being postponed for the first time on January 7, the mission was rescheduled for docking on Thursday, January 9. If ISRO succeeds in this mission, India will become the fourth country in the world to have space docking technology.

ISRO gave information about the postponement of the docking experiment by posting it on X. ISRO informed that some flaws were seen in the exercise to reach a distance of 225 meters between the satellites. The docking process planned for tomorrow has been postponed. The satellites are safe.

ISRO launched two satellites named SDX01 (chaser) and SDX02 (target) under this mission on December 30 with the help of PSLV C60 rocket from Satish Dhawan Space Center in Sriharikota. Both these small satellites weighing about 220-220 kg were placed in a circular orbit of 475 km.

According to ISRO, the Space Docking Experiment (Spadex) mission is a mission to demonstrate the economical technology of docking in space using both satellites. This technology is necessary for India's space plans. Such as sending Indians to the moon, bringing samples from the moon, constructing and operating of Indian Space Station (BAS), etc.
