ISRO’s Gaganyaan Mission: Milestone Achieved

India’s journey into manned spaceflight reached a historic milestone with the successful completion of Gaganyaan Integrated Air Drop Test (IADT-01) at the Satish Dhawan Space Centre in Sriharikota. The Gaganyaan mission, India’s first attempt at sending humans into space, signifies a major leap in ISRO’s capabilities.

Background of the Gaganyaan Mission

The program, announced in 2018, aims to send 2-3 astronauts into low Earth orbit for up to 7 days. Key objectives:

• Developing human spaceflight capabilities
• Testing safety systems – air-drop and abort tests
• Advancing space technology in spacecraft design, avionics, and propulsion
