On July 18, 2026, Skyroot Aerospace’s Vikram-1 lifted off from the Satish Dhawan Space Center, Sriharikotaand placed its payloads into an orbit of nearly 450 km about 15-17 minutes after liftoff. The mission, named Aagaman (Sanskrit for “arrival”), was the maiden flight of Vikram-1, India’s first privately developed orbital-class launch vehicle. With this launch, India became the third country in the world, after the United States and China, to have a private orbital launch capability. Prime Minister Narendra Modi congratulated Skyroot Aerospace on the achievement and IN-SPACe Chairman Pawan Goenka called it “an Indian moment”.
breaking it
Until recently, only government agencies like ISRO could design, build and launch orbital rockets in India. Vikram-1 changes that. This is a rocket built entirely by a private Indian company, Skyroot Aerospace, from design to manufacturing to final assembly. The rocket is named after Dr. Vikram Sarabhai, considered the father of India’s space program.Think of it this way: ISRO’s PSLV and GSLV are like government-run trains that carry satellites into space on fixed schedules. Vikram-1 is Skyroot’s attempt to provide a “cabin” service, a smaller, faster, on-demand ride for small satellites that need to quickly reach specific, customized orbits.Vikram-1 is not India’s first private rocket. That distinction belongs to Vikram-S, a smaller, single-stage suborbital rocket launched by Skyroot in November 2022 under the Prarambh mission. Vikram-1 goes one step further. It is a full orbital vehicle, meaning it can carry a satellite up to Earth orbit instead of touching the edge of space and back down.
The mechanism
The Vikram-1 is a four-stage rocket, approximately 20-24 meters tall, built primarily of carbon composite materials to keep it light. Its stages are:
- Three solid fuel stages, named Kalam-1200, Kalam-250 and Kalam-100 after the former president and rocket scientist Dr. APJ Abdul Kalam. These provide the initial push to leave the atmosphere.
- A Liquid Fuel Orbital Adjustment Module (OAM), the final stage, using a 3D printed engine. Unlike solid stages that are ignited once, the OAM can start, stop and restart in space, allowing precise, last-mile placement of satellites into their target orbit.
The rocket is designed to carry payloads of up to 350 kg to a Low Earth Orbit (LEO) of about 450 km. On its maiden flight, it carried technology demonstration payloads from companies such as Grahaa Space, Cosmoserve Space and Germany’s DCUBED, along with symbolic cargo including a handwritten postcard of PM Modi and a lab-grown diamond artwork.Aagaman was described as a test flight, the first of three planned development flights intended to validate the rocket before Skyroot begins regular commercial launches.
Relevant bodies, laws and policies
- ISRO (Indian Space Research Organization): National Space Agency of India. For Vikram-1, ISRO privately supported the mission with facilities such as engine casting, liquid engine testing, trajectory analysis and use of its launch pad at Sriharikota.
- IN-SPACe (Indian National Space Promotion and Authorization Centre): An autonomous, single-window nodal agency under the Department of Space, established in 2020. It authorizes and regulates private sector space activities in India, including granting launch authorization to companies such as Skyroot.
- Department of Space (DOS): The nodal department of the central government that oversees India’s space programme, under which both ISRO and IN-SPACe operate.
Indian Space Policy 2023: This policy formally opened up the space sector to private participation in the entire value chain, from building satellites and launch vehicles to providing launch services, with ISRO focusing more on research, exploration and technology development.- NewSpace India Limited (NSIL): A public sector company under DOS that commercializes ISRO technologies and enables the production of launch vehicles through Indian industry.
Importance to India
The success of Vikram-1 is a milestone for India’s space sector reforms that began after 2020, when the sector was opened up to private players. It indicates that Indian private companies can now compete in the global small satellite launch market, which is growing rapidly as demand for Earth observation, communication and technology demonstration satellites increases. A successful private launch ecosystem can also allow ISRO to focus its own resources on larger strategic missions such as the Gaganyaan human spaceflight programme, planetary exploration and heavier launch vehicles, while private players handle smaller, more frequent commercial launches. Founded in 2018 and headquartered in Hyderabad, Skyroot is one of India’s leading space technology startups and had earlier achieved the Vikram-S milestone in 2022.

Five key terms to remember
- Orbital Adjustment Module (OAM): Vikram-1’s liquid-fueled final stage that precisely places payloads in their target orbit and can restart in space.
