The Indian Space Research Organization (ISRO) has announced the delay in the planned docking of two satellites as part of its ambitious Space Docking Experiment (SpaDeX). The docking, originally scheduled for January 7, was postponed after more drift than anticipated was detected during the process of bringing the satellites to a distance of 225 meters.
ISRO confirmed in a tweet, “While attempting to reach 225 meters between satellites, after a non-visibility period, drift was found higher than expected. The docking planned for tomorrow has been postponed. Satellites are safe. Stay tuned for updates.”
A step towards space docking technology
SpaDeX is an unprecedented mission that aims to demonstrate in-space docking using two small satellites, SDX01 (chaser) and SDX02 (target), each weighing approximately 220 kg. The satellites were launched into a 475-km circular orbit using a PSLV C60 rocket from the Satish Dhawan Space Center in Sriharikota on December 30.
Successful execution of this mission will make India the fourth country globally to develop space docking technology, which is a critical component of advanced space exploration and operations.
Important for future space ambitions
ISRO has described SpaDeX as a cost-effective technology demonstrator mission necessary to advance India’s space ambitions, including a lunar sample return mission, establishment and operation of the Indian Space Station (BAS) and a future on the Moon. Including human missions.
“This milestone will significantly enhance India’s capabilities in spacecraft rendezvous, docking and undocking—satellite servicing, space station operations and critical technologies for interplanetary missions,” the space agency said.
Awaiting the next steps
Despite the postponement, ISRO has assured that the satellites will remain safe, and the team is working to address the drift issue before rescheduling the docking attempt. The success of SpaDeX will be a transformative leap for India’s space programme, further strengthening its position as a leader in space exploration.
Stay tuned for more updates from ISRO as the mission progresses.
