Space missions

Story hook

At 18:04 IST on 23 August 2023, an Indian-built spacecraft the size of a small SUV touched down on a patch of regolith near the south pole of the Moon. The Mission Operations Centre at the ISRO Telemetry Tracking and Command Network (ISTRAC) in Bangalore held its collective breath. Four years earlier — in this same room — a different team had watched Chandrayaan-2's Vikram lander lose contact 2.1 km above the surface and slam into the regolith. The mission had ended in a quiet, devastating silence.

This time was different. The signal held. The descent angle held. At touchdown, the room exploded. India became the fourth country in history to soft-land on the Moon — after the USSR (1966), the USA (1966), and China (2013). And it became the first country to do so anywhere near the lunar south pole, where every lunar mission since has wanted to go.

The Chandrayaan-3 success cost about ₹615 crore — less than the budget of a single Hollywood action film. That ratio — engineering output per rupee spent — is the defining feature of India's space programme. Vikram Sarabhai, when he founded ISRO in 1969, said "There is no ambiguity of purpose. We must be second to none in the application of advanced technologies to the real problems of man and society." Fifty-six years later, that doctrine is the reason a country with a per-capita income of ~$2,800 has its flag on the Moon, a probe in solar orbit, and a human spaceflight mission booked for 2026.

Why this matters for UPSC

Indian space achievements are the most frequently asked S&T topic in UPSC over the last decade — at least one Prelims question per year on a recent mission, regular Mains questions on the indigenisation + civil-military + economic dimensions, and almost guaranteed Interview probes (especially for IES, IRS, IFS candidates). The topic also crosses into IR (ISRO commercial launches), Economy (space-tech startups, NSIL revenue), and Internal Security (NavIC, military satellites).
