Vikram-1 India's first private orbital rocket mission; defining moment, says PM, Pg1

Key Highlights:

• Vikram-1, India's first privately-built orbital rocket, successfully launched and deployed multiple technology demonstration payloads into a Low-Earth Orbit (LEO) at approximately 450 km altitude on July 18, 2026.
• Developed by Hyderabad-based Skyroot Aerospace, the mission, named 'Aagamaan' (arrival), signifies a new era for India's private space sector.
• With this launch, India became the third country globally, after the United States and China, to achieve private sector orbital launch capabilities.
• The rocket is named after Vikram Sarabhai, widely regarded as the father of India's space program.
• The launch was actively supported by the Indian Space Research Organisation (ISRO) and the government's policy to open the space sector to private players.

Detailed Insights:

• The launch of Vikram-1 took place from ISRO's Satish Dhawan Space Centre at Sriharikota.
• Vikram-1 is a multi-stage rocket, approximately seven storeys tall, designed to carry small satellites weighing up to 350 kg to Low-Earth Orbit.
• The rocket's solid engines are named 'Kalam' after Dr. A.P.J. Abdul Kalam, known as the "Missile Man of India" and a former President, and its liquid engine 'Raman' after physicist Dr. C.V. Raman, a Nobel laureate.
• This achievement follows Skyroot Aerospace's earlier sub-orbital flight of its Vikram-S rocket in 2022, which was India's first private rocket launch.
• The government's decision to liberalize the space sector in June 2020 and the establishment of bodies like the Indian National Space Promotion and Authorisation Centre (IN-SPACe) have been instrumental in fostering private participation.
• This successful orbital mission positions India as a significant player in the global space industry, encouraging innovation and engagement from young entrepreneurs.

Scientific/Technical Concepts Involved:

• Orbital Flight: A trajectory where a spacecraft achieves sufficient velocity to continuously circle a celestial body without falling back to its surface.
• Sub-orbital Flight: A trajectory where a spacecraft enters space but does not attain the velocity required to orbit, returning to Earth under the influence of gravity.
• Low-Earth Orbit (LEO): An orbit around Earth with an altitude typically between 160 km and 2,000 km, commonly used for Earth observation and communication satellites.
• Multi-stage Rocket: A rocket composed of two or more sections, each with its own engines and propellant, which are jettisoned sequentially after their fuel is expended to reduce mass and increase efficiency.
