Background: Gaganyaan and Human Spaceflight
The ISRO Gaganyaan parachute tests mark a crucial milestone in India’s first human spaceflight mission. Gaganyaan is designed to place Indian astronauts into low-Earth orbit and ensure their safe return to Earth.
While rocket launches often capture public attention, experts point out that the most complex engineering challenges arise during atmospheric re-entry and landing. This makes the parachute-based deceleration system one of the most critical safety components of the mission.

Human spaceflight demands redundancy, reliability, and extensive validation. ISRO’s step-by-step testing strategy reflects its cautious approach to astronaut safety and mission assurance.
The latest ISRO Gaganyaan parachute tests were conducted at the RTRS facility of the Terminal Ballistic Research Laboratory (TBRL) in Chandigarh, a DRDO laboratory specialising in high-risk aerodynamic evaluations.
ISRO Gaganyaan Parachute Tests Explained
ISRO successfully conducted the drogue parachute deployment qualification tests for the Gaganyaan Crew Module on December 18 and 19, 2025. These trials focused on validating parachute performance under extreme and varying flight conditions.

According to ISRO, the crew module’s deceleration system consists of ten parachutes of four different types, deployed in a carefully timed sequence.
- Two apex cover separation parachutes remove the protective cover
- Two drogue parachutes stabilise and decelerate the module
- Three pilot parachutes extract three main parachutes
Once the main parachutes deploy fully, the crew module slows to a velocity that ensures a controlled and safe touchdown. The ISRO Gaganyaan parachute tests confirmed the reliability of this sequence.
ISRO stated that the drogue parachutes are essential for stabilising the module during the critical transition from high-speed re-entry to controlled descent.
Why Drogue Parachutes Are Critical
Drogue parachutes play a vital role in human spaceflight missions. During the ISRO Gaganyaan parachute tests, these components were evaluated for performance under extreme stress and turbulence.
Without effective drogue deployment:
- The crew module could experience dangerous instability
- Main parachute deployment could be compromised
- Astronaut safety would be at risk
ISRO confirmed that the tests validated both the performance and reliability of the drogue parachutes, ensuring they reduce the module’s velocity to safe levels before main parachute deployment.
The success also highlights India’s growing capability in developing indigenous human-rated spaceflight systems using advanced materials and modern engineering techniques.
Statements, Reactions and Strategic Importance
Union Minister for Science and Technology Jitendra Singh confirmed the success of the ISRO Gaganyaan parachute tests, describing them as a significant step toward India’s first human space mission.
He noted that the tests confirmed system reliability under varying flight conditions and moved India closer to achieving a historic milestone in space exploration.

ISRO acknowledged support from multiple institutions, including the Vikram Sarabhai Space Centre (VSSC), Aerial Delivery Research and Development Establishment (ADRDE), and the Terminal Ballistic Research Laboratory (TBRL).
Experts believe such collaboration strengthens India’s aerospace ecosystem and accelerates progress toward complex missions like Gaganyaan.
“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.
What Comes Next for Gaganyaan
With the drogue parachute qualification tests completed, ISRO will now focus on integrated system trials, including main parachute testing and recovery operations.
Upcoming mission milestones are expected to include uncrewed orbital demonstration flights and abort scenario validations.
The ISRO Gaganyaan parachute tests underscore India’s steady progress toward human spaceflight and reinforce confidence in the mission’s safety architecture.
