Gaganyaan: Inside India's Historic Crewed Space Program

The Gaganyaan mission is poised to be India's biggest milestone in space exploration since its inception. By launching a three-member crew to a 400 km Low Earth Orbit (LEO) for a three-day mission, ISRO will become only the fourth agency in history to build, launch, and recover a crewed orbital spacecraft.

1. Meet the Astronaut-Designates

ISRO officially introduced the four selected Indian Air Force fighter pilots chosen for the mission:

• Group Captain Prashanth Balakrishnan Nair
• Group Captain Ajit Krishnan
• Group Captain Angad Pratap
• Wing Commander Subhanshu Shukla

They completed rigorous physical, psychological, and survival training in Star City, Russia, and are currently undergoing mission-specific simulator training in Bengaluru.

2. Critical Precursor Test Flights (TV-D Missions)

Human spaceflight demands near-perfect reliability. ISRO is conducting several safety flight tests:

• TV-D1 (Test Vehicle Demonstration 1): Successfully launched in October 2023. It demonstrated the in-flight escape system, proving that if a launcher malfunctions mid-air, the crew escape module can safely pull the astronauts away and deploy parachutes.
• Vyommitra Robot Flight: ISRO will launch *Vyommitra*, a humanoid robot with half-humanoid anatomy, inside an uncrewed capsule. Vyommitra will monitor cockpit environmental parameters, read telemetry, and simulate crew communications.

3. Re-entry, Parachutes, and Recovery

The Gaganyaan module will utilize the atmosphere to decelerate. Once it descends to a safe altitude, a cluster of parachutes will deploy, soft-splashing the capsule into the Arabian Sea near the Gujarat/Mumbai coast. Special recovery drills are being perfected by the Indian Navy and Coast Guard.
