'10 motors, 1 shot': ISRO takes on US, Russia, China with daring SpaDeX feat

Produced by: Mohsin Shaikh

Docking Challenge

ISRO aims to dock two satellites moving at ten times the speed of a bullet—a feat only achieved by the US, Russia, and China so far.

SpaDeX Mission

The Space Docking Experiment (SpaDeX), developed over a decade in Bengaluru, marks India’s ambitious leap into space innovation.

Velocity Mastery

Two satellites will travel at 28,800 km/h before ISRO slows them to 0.036 km/h for docking—a precision marvel.

Docking System

ISRO’s patented Bhartiya Docking System meets NASA’s IDSS standards, using just two motors compared to IDSS’s 24.

Private Innovation

Final assembly of the SpaDeX satellites was done by Ananth Technologies, a Bengaluru-based private firm started by ex-ISRO scientist Dr. Subba Rao Pavuluri.

Strategic Necessity

SpaDeX is critical for India’s moon ambitions, space station plans, and future manned missions under Gaganyaan.

Global League

India is set to become the fourth nation with autonomous space docking technology, showcasing cost-effective innovation.

Future Vision

The mission’s success will pave the way for Chandrayaan-4, Bharatiya Antariksh Station, and an Indian on the moon.
