In Short

  • It was originally scheduled for docking on January 7
  • SpaDeX mission faced delays due to unexpected satellite drifting
  • It will demonstrate the ability for spacecraft rendezvous, docking

The Indian Space Research Organisation (Isro) has provided a significant update on its SpaDeX mission, announcing that the two spacecraft are currently in a hold mode at a distance of 1.5 kilometers apart.

As of January 10, 2025, Isro plans to initiate a further drift to reduce this distance to 500 meters by tomorrow morning.

Originally scheduled for docking on January 7, the SpaDeX mission faced delays due to unexpected satellite drifting during maneuvering. Following an earlier postponement, Isro confirmed on January 9 that the drift had been arrested and that the spacecraft were set on a slow drift course to facilitate closer proximity.

“By tomorrow, it is expected to reach initialization conditions,” the agency stated in a post on X.

The SpaDeX mission is a critical technology demonstrator aimed at showcasing India’s capabilities in in-space docking.

Launched on December 30, 2024, aboard the PSLV-C60 rocket, the mission involves two small spacecraft: SDX01 (Chaser) and SDX02 (Target).

The goal is to develop and demonstrate the ability for spacecraft rendezvous, docking, and undocking—essential technologies for future space operations, including India's planned lunar missions and the establishment of a space station.

Isro officials have emphasised the importance of this mission for India's ambitions in space exploration. After successful docking and subsequent operations, the spacecraft will demonstrate power transfer between them before separating to commence their respective payload operations.

As anticipation builds for the upcoming docking attempt, Isro continues to monitor the situation closely. The agency has indicated that it will provide updates as the mission progresses, reinforcing its commitment to advancing India’s position in global space technology.
