Why in News
Gaganyaan is moving India toward an operational human-spaceflight ecosystem; UPSC relevance lies in the safety, industrial and institutional stack needed to send crew to low-Earth orbit and return them safely.
Static Foundation
The system requires a human-rated launch vehicle, crew/service modules, escape system, life support, tracking, re-entry thermal protection and recovery. Human-rating demands crew-grade reliability and fault tolerance. Abort tests validate emergency separation; recovery requires ISRO, Navy, medical and mission-control coordination.
Prelims Focus
Distinguish launch vehicle from spacecraft, crew module from service module and abort system from normal recovery. Low-Earth orbit does not eliminate severe re-entry heating. Vyommitra is a humanoid test platform, not an astronaut.
Mains Perspective
Human spaceflight creates spillovers in materials, electronics, robotics, medicine and high-reliability manufacturing. India needs independent review, anomaly learning, domestic supply-chain depth and a strong safety culture.
Practice
MCQ: Human-rating concerns crew safety; crew escape enables emergency separation; re-entry thermal protection is NOT unnecessary in LEO. Correct: first two only.
Mains: Examine Gaganyaan's strategic and technological significance.
