ISRO successfully docks two satellites in space and India became fourth country to achieve feat after US, Russia, China.
The SpaDex (Space Docking Exercise) mission is intended to be a technology demonstrator for the docking of two small satellites launched by the PSLV.
ISRO has launched two small spacecraft — SDX01, the Chaser, and SDX02 on December 30.
In the mission, after the initial 20 km inter-satellite separation, the Chaser satellite approaches the Target satellite by reducing the distance to 5 km, 1.5 km, 500 m, 225 m, 15 m, and 3 m, before the final docking of the two spacecraft.
