Isro Completes First Integrated Air Drop Test for Gaganyaan

The Indian Space Research Organization (ISRO) successfully carried out its first integrated Air Drop Test (IADT-1), A Critical Milestone in Preparations for the Country’s Spalesflight Program, Gaganyaan, on August 24, 2025.

“Isro successfully encamplishes first integrated air Drop Test (IADT-01) for end-to-end demonstration of parachute based decisions system for Gaganyaan Missions,” isro Wrote on X.

The IADT is a specialized trial to ensure the parachute system designed for the gaganyaan crew module performs reliably in real- WW Conditions.

During the test, a dummy crew capsule weighing Around five tonnes was lifted up through the air before being dropped by a chinook Helicopter. As it descended through a less km, its main parachutes had to open in a specific Sequence to Decelerate the Capsule to a Safe Splashdown Speed.

DURING an actual flight with astronauts, the main parachutes will have to deploy after the capsule have re-entered the atmosphere and have been lowed first by the heat shields and Drogue Parachuts.

The assent, descent, and post-splashdown phases of the gaganyaan mission are expected to be the most risk for the astronauts.

According to isro, the effort brieft togera multiple national agencies – the air force, the defense research and development organization (DRDO), the Navy, and the Coast GUard – In What Guard DESCIBED A coordinated step towards Human-Rating India’s Launch and Recovery Systems.

Earlier this week, Union Minister of State for Science and Technology Jitendra Singh Told the Lok Sabha that Major Preparatory work for Gaganyaan Had Alredy Been Complated. “The propulsion systems for the crew module and service module have been developed and tested. Environmental Control and Life Support System Engineering Model Realized. Crew System Motors Developed and Static Tested, “Mr. Singh said in a written reply.

He added that infrastructure has been established for “Orbital Module Preparation Facility, Gaganyaan Control Center, Gaganyaan Control Facility, Crew Training Facility, [and] Second launch pad modifications ”.

Ahead of Gaganyaan’s First Uncrewed Mission, Designated G1, Mr. Singh Said, “The C32-G stage and the Ces motors” had been realised. “The HS200 Motors and Ces Fore-Ed, up to crew module jettisoning motor, stacked. Crew module and service module structure related.

The minister also said the human spaceflight program is part of a longer roadmap in which, after demonstrating basic capabilites for human spaceflight in gaganyaan, the Programme will perform Missions in low-end orbit.

The government has set out a timeline that includes building the Bharatiya Antariksh Station (BAS) By 2035 and Undertaking An Indian Mon Landing by 2040.

The successful completes of the IADT-1 Testwill be followed by additional test check Flights, Including TV-D2 and the G1 Mission. Togeether they will Validate Crew Escape Mechanisms, Parachute Systems, Propulsion Units, and Ground Recovery Operations Before Any Human is cleared to fly.
