Operate after docking

ISRO successfully docked the two SpaDeX satellites in January 2025. It subsequently demonstrated undocking and later a second autonomous docking with power transfer between the satellites.

India thereby demonstrated an important capability needed for future complex missions.

Why Is Docking Important?

Docking technology is important for:

Space stations
Human spaceflight
In-orbit servicing
Spacecraft assembly
Sample-return missions
Future lunar missions

ISRO has specifically linked docking technology to future ambitions such as the Bharatiya Antariksh Station and lunar sample-return missions.

CLAT Fact

India became the fourth nation to demonstrate space docking technology through SpaDeX.

Gaganyaan Mission

One of India’s most ambitious space programmes is:

Gaganyaan

Gaganyaan aims to demonstrate India’s capability to send Indian astronauts into Low Earth Orbit and safely return them to Earth.

The programme is significant because human spaceflight requires technologies far more complex than conventional satellite launches.

These include:

Human-rated launch vehicle
Crew module
Life-support systems
Crew escape systems
Astronaut training
Recovery systems
Mission control

Shubhanshu Shukla and the International Space Station

India’s human-spaceflight programme received a major boost through Group Captain Shubhanshu Shukla’s participation in the Axiom-4 mission to the International Space Station in 2025.
