Bengaluru: The Indian Space Research Organisation (ISRO) has once again postponed its ambitious Space Docking Experiment (SpaDEx), citing unexpected drift during a crucial manoeuvre.

The experiment, initially scheduled for January 7 and later rescheduled to January 9, was delayed after excessive drift was detected while maneuvering to reach a 225-meter distance between the two satellites involved.

“While making a manoeuvre to reach 225 m between satellites, the drift was found to be more than expected, post non-visibility period. The planned docking for tomorrow is postponed. Satellites are safe. Stay tuned for updates,” ISRO stated on ‘X’.

The Space Docking Experiment is a key initiative aimed at developing and demonstrating spacecraft rendezvous, docking, and undocking technologies using two small satellites.

"SpaDEx will serve as a milestone in advancing India's capabilities in space docking, a critical technology for future space missions including satellite servicing, space station operations, and interplanetary missions,” ISRO emphasized.

This delay marks the second time the SpaDEx timeline has been revised, underscoring the complexity of the mission. ISRO has assured that the satellites involved remain safe and further updates will follow.

The success of SpaDEx is expected to propel India’s space technology forward, enabling advanced missions such as in-orbit satellite servicing and potential space station collaborations.
