  • About SpaDeX Mission: SpaDeX stands for Space Docking Experiment developed by ISRO.

o It is a technology demonstration mission to test docking and undocking capabilities of two satellites in low-Earth orbit.

o Involves two small satellites: SDX01 (Chaser) & SDX02 (Target). Each satellite weighs around 220 kg. Launched by PSLV-C60 into a 460 km circular orbit with a 45° inclination.

  • Objectives of SpaDeX:

o Primary Objective: Demonstrate rendezvous, docking, and undocking of spacecraft in orbit.

o Secondary Objectives: Demonstrate electric power transfer between docked satellites.

o Significance: With this success, India becomes the fourth country after the USA, Russia, and China to achieve satellite docking operations.
