With Skyroot rocket launch, Indian space industry crosses a milestone

📌 Summary:

• Context: Skyroot Aerospace's Vikram-1 rocket was successfully launched (Saturday), marking a defining moment in India's space journey — a transition from an almost exclusively ISRO-led programme to one where private enterprise drives innovation
• Milestone: Until this mission, only private companies in the US and China had independently developed and launched rockets that reached orbit; India now joins this exclusive league
• Policy enabler: Comes six years after the space sector was opened to private participation in 2020, institutionalised through the Indian Space Policy, 2023
• Ecosystem data: India now hosts ~400 space start-ups across the value chain (launch vehicles, satellites, space-grade electronics, downstream applications); sector valued at ~Rs 70,000 crore, expected to grow four- to five-fold over the coming decade
• Strategic significance: Vikram-1 targets Low Earth Orbit (LEO, ~160-2,000 km) — the fastest-growing space market (Earth observation, weather forecasting, telecom); shifting commercial launches to private players frees ISRO for deep-space missions like Chandrayaan and Gaganyaan
• Caveat (balance): ISRO's handholding cannot be discounted — it provided most infrastructure used to design Vikram-1; India's PPP model will differ from the US (where SpaceX builds independently of NASA) for at least a decade
• Way forward: Indian firms can compete via traditional strength in low-cost manufacturing, but the sector is unforgiving — shown by the collapse of US firms Vector Launch and Virgin Orbit

📝 Prelims Facts:

• Skyroot Aerospace built Vikram-1; it reached orbit (private-sector first for India)
• Space sector opened to private players in 2020; Indian Space Policy, 2023 institutionalised it
• ~400 space start-ups; sector valued ~Rs 70,000 crore
• Low Earth Orbit spans ~160-2,000 km; geostationary satellites orbit near 37,000 km
• IN-SPACe is the regulator/promoter enabling private participation

🔑 Key Term: Low Earth Orbit (LEO) — orbit at altitudes of roughly 160-2,000 km, favoured for Earth observation, communications and small-satellite constellations due to lower launch cost and latency.
