Background: India’s Space Odyssey and Private Sector Reforms
India's journey into space began with the establishment of the Indian Space Research Organisation (ISRO) in 1969, under the visionary leadership of Dr. Vikram Sarabhai. For decades, ISRO remained the sole custodian of the nation's space program, achieving remarkable feats from launching its first satellite, Aryabhata, in 1975, to developing sophisticated launch vehicles like the Polar Satellite Launch Vehicle (PSLV) and Geosynchronous Satellite Launch Vehicle (GSLV). These indigenous capabilities have enabled India to launch numerous satellites for communication, earth observation, navigation, and even undertake ambitious interplanetary missions like Chandrayaan and Mangalyaan.
The Genesis of Space Sector Reforms
For over five decades, ISRO operated largely as a monolithic entity, focusing on national strategic and scientific objectives. However, recognizing the immense potential of the global space economy and the need to foster innovation and economic growth, the Indian government initiated significant reforms in 2020. These reforms aimed to open up the space sector to private participation, encouraging Indian industries, startups, and academia to contribute to and benefit from space activities.
Central to these reforms was the creation of the Indian National Space Promotion and Authorisation Centre (IN-SPACe). Established as an autonomous nodal agency under the Department of Space, IN-SPACe serves as a single-window interface for private entities seeking to undertake space activities in India. Its mandate includes promoting, enabling, authorizing, and supervising the space activities of non-governmental private entities, ensuring a level playing field and providing access to ISRO facilities and expertise. This strategic move was designed to unlock the full potential of India's private sector, driving innovation, job creation, and economic growth within the space domain.
Skyroot Aerospace: Pioneers of Private Spaceflight
Among the first beneficiaries and trailblazers of these reforms is Skyroot Aerospace, a Hyderabad-based startup founded in 2018 by Pawan Kumar Chandana and Naga Bharath Daka, both former ISRO scientists.
