ISRO Successfully Completes Key Parachute Deceleration Tests for Gaganyaan Mission | Video

On Saturday, the Indian Space Research Organisation (ISRO) made several major qualification tests on drogue parachutes successfully. These were conducted with the aim of coming up with a deceleration system of the Gaganyaan Crew Module.

“ISRO successfully completed the Drogue Parachute Deployment Qualification Tests for the Gaganyaan Crew Module at the RTRS facility of TBRL, Chandigarh, during 18–19 December 2025,” Union minister for science and technology, Jitendra Singh, said.

The tests were to ensure the performance and reliability of drogue parachutes in different conditions of flight, and Singh said that it was a significant milestone towards qualifying the parachute system to the human spaceflight mission of India. “Heartening to note that India has moved one more step closer to its first Human Space mission #Gaganyaan,” Singh said.

ISRO stated that the deceleration system of the crew module in the Gaganyaan mission had 10 parachutes of four different types. The space agency explained the descent sequence of the module, saying that it “begins with two apex cover separation parachutes that remove the protective cover of the parachute compartment, followed by two drogue parachutes that stabilize and decelerate the module.”

After the release of these drogues, three pilot parachutes are launched to recover three primary parachutes that will further decelerate the crew module making it safe to touch down, ISRO said.

It claimed that the drogue parachutes are an essential element since it helps in stabilising the crew module since it slows its velocity to a safe level during the re-entry.

In terms of the aim of the given series of tests, the ISRO stated that they were aimed at assessing the functionality and stability of drogue parachutes under extreme conditions.

“The successful completion of these tests marks another significant step toward qualifying the parachute system for human spaceflight, with active support and participation from the Vikram Sarabhai Space Centre (VSSC), ISRO, Aerial Delivery Research and Development Establishment (ADRDE), DRDO and Terminal Ballistic Research Laboratory (TBRL), DRDO,” ISRO said.
