The two satellites that were launched to conduct space docking experiments were successfully brought within three meters and then safely returned in a trial attempt, according to ISRO on Sunday.

Additionally, the space agency stated that the docking procedure would be completed following additional data analysis.


"A trial attempt is made to go up to 15 meters and then three meters. Spacecraft are being moved back to a safe distance. In a post on X, ISRO stated that the docking process would be completed following additional data analysis.

Two scheduled docking experiments on January 7 and January 9 have been missed by the Space Docking Experiment (SpaDeX) project.

ISRO launched the mission on December 30.

The PSLV C60 rocket, carrying two small satellites -- SDX01 (Chaser) and SDX02 (Target) -- along with 24 payloads, lifted off from the Satish Dhawan Space Centre in Sriharikota. About 15 minutes later, the two small spacecraft weighing about 220 kilogrammes each were launched into a 475-kilometre circular orbit, as intended.

The SpaDeX project is a cost-effective technology demonstrator mission for the demonstration of in-space docking using small spacecraft, according to ISRO.

A successful demonstration of SpaDeX will make India the fourth nation to master the complex technologies that are crucial for its future missions, such as the Bharatiya Antariksh Station and landing an astronaut on the moon.

In-space docking technology is essential when multiple rocket launches are required to achieve common mission objectives.
