India Unveils First Four Astronauts for Gaganyaan Mission

Marking a monumental milestone for India's space program, Prime Minister Narendra Modi has formally unveiled the identities of the country's first four astronaut candidates. The astronauts will spearhead preparations for the highly anticipated Gaganyaan manned space mission, bringing India to the brink of an elite club of nations having indigenous human spaceflight capabilities.

New ISRO Facilities Dedicated to Nation

The astronauts were revealed during PM Modi's visit to inaugurate three new state-of-the-art ISRO centers critical to enhancing launch capacities, boosting rocket technology self-reliance and enabling next-gen spacecraft design.

Collectively worth ₹1,800 crore, the new facilities include the PSLV rocket integration plant bolstering production, a semi cryogenic engine complex advancing propulsion autarky and a trisonic wind tunnel facility to optimize aerodynamic configurations.

Introducing India's First Four Astronauts

Culled from Indian Air Force test pilots after rigorous ISRO selections similar to NASA's exacting benchmarks, Wing Commander Prashanth Nair, Squadron Leader Angad Prathap, Flight Lieutenant Ajit Krishnan and Flight Lieutenant Shubhanshu Shukla were announced as Gaganyaan mission candidates.

Conferring their prestigious status, PM Modi formally handed each astronaut a custom insignia pin, underscoring their pioneering role in spearheading India's maiden human spaceflight.

Expanding India's Space Leadership

Briefing the Prime Minister on extensive preparations towards meeting the 2027 Gaganyaan launch timeline, ISRO Chairman outlined progress across human rated launch vehicles, crew escape systems, orbital modules, spacesuits, life support systems and mission-specific infrastructure.

Unfurling his vision for exponentially expanding India's global space leadership by 2047, PM Modi articulated goals spanning lunar manned missions with indigenous rockets, establishing India's own space station and ramping up satellite launch capacity and private sector space startups.

Overview of Gaganyaan Mission

Gaganyaan aims to demonstrate autonomous Indian capacity for sending astronauts to low earth orbit aboard Made in India launch vehicles and spacecraft. Envisaging a 3-day crewed orbital stay at 400km altitude, the mission entails end-to-end systems encompassing launch, orbit and re-entry.

As the first step towards achieving ambitious long-range exploration targets, Gaganyaan shall lay the bedrock for core human spaceflight technologies besides galvanizing the science and technology ecosystem.
