India’s first privately developed orbital-class rocket Vikram-1 set for July 18 lift-off
Skyroot Aerospace announced that Vikram-1, India's first privately developed orbital-class rocket, is set to lift off on July 18 at 11.30 a.m. from the First Launch Pad of the Satish Dhawan Space Centre (SDSC-SHAR), Sriharikota
The mission, named "Mission Aagaman" (Arrival), marks the maiden orbital flight attempt by a fully privately designed and built Indian launch vehicle
Vikram-1 is a multi-stage launch vehicle built with an all-carbon composite structure, powered by in-house-developed propulsion systems including 3D-printed engines and high-thrust solid-fuel rocket boosters
The rocket will carry technology demonstration payloads from private space-tech firms, along with small art payloads
This follows Skyroot's earlier suborbital test flight of Vikram-S in November 2022, which was India's first-ever private rocket launch
IN-SPACe and India's Private Space Sector Reforms (2020)
The Indian National Space Promotion and Authorisation Centre (IN-SPACe) was established by a Cabinet decision on June 24, 2020, as a single-window, independent nodal agency under the Department of Space to promote, authorise, and regulate space activities of non-government entities (NGEs). Before 2020, ISRO held a near-monopoly over launch vehicle development and satellite operations in India; the 2020 reforms opened the sector to private players for end-to-end space activities, including building and launching their own rockets.
Key Details
- IN-SPACe functions as a facilitator and regulator, distinct from ISRO (the technical/research arm) and NewSpace India Limited or NSIL (the commercial arm that markets ISRO-developed technology)
- The Indian Space Policy 2023, approved by the Union Cabinet on April 6, 2023, formalised the roles of IN-SPACe, ISRO, NSIL, and private entities, permitting NGEs to undertake end-to-end space activities — from manufacturing rockets and satellites to owning ground stations
- Skyroot Aerospace, founded in 2018 by former ISRO scientists Pawan Kumar Chandana and Naga Bharath Daka, became the first Indian private company to launch a rocket into space (Vikram-S, November 18, 2022, a suborbital flight from SDSC-SHAR)
Vikram-1's attempted orbital launch is the practical test of the post-2020 liberalisation — moving a private company from a single suborbital demonstration to a full orbital-class vehicle capable of placing payloads in Earth orbit, a capability previously reserved for ISRO's PSLV/GSLV/SSLV fleet.
Launch Vehicle Staging and Propulsion Technology
A launch vehicle reaches orbital velocity (roughly 7.8 km/s for low Earth orbit) by shedding mass in stages, each stage firing sequentially and separating once its propellant is spent. Vikram-1 is described as a multi-stage, solid-fuel-boosted vehicle using an all-carbon composite airframe, which reduces structural mass compared to conventional metal-alloy rocket bodies.
Key Details
- Suborbital vs orbital distinction: Vikram-S (2022) reached a peak altitude of about 89 km without achieving orbital velocity, so it fell back to Earth (splashdown in the Bay of Bengal); an orbital launch must achieve both sufficient altitude and horizontal velocity to counteract gravity and complete revolutions around the Earth
- 3D printing (additive manufacturing) of rocket engines reduces part count and production time compared to traditional casting/machining — a technique also used by ISRO (e.g., the PS4 stage injector) and global private players
- Solid-fuel boosters provide high initial thrust for lift-off, commonly paired with liquid or hybrid upper stages for orbital insertion precision
Vikram-1's carbon-composite structure and 3D-printed, indigenously developed propulsion mark a shift from ISRO's traditional aluminium-alloy, government-built launch vehicles toward lighter, faster-to-manufacture private-sector rocket architectures aimed at the small-satellite launch market.
Small Satellite Launch Market and India's Space-Tech Startups
Globally, the rise of small satellites (CubeSats, technology demonstrators) has created demand for dedicated small-lift launch vehicles that can offer more frequent, lower-cost, and customisable launches than large government rockets designed for bigger payloads.
Key Details
- ISRO's own dedicated small-satellite vehicle, the Small Satellite Launch Vehicle (SSLV), was developed for a similar market segment, complementing rather than competing with private players like Skyroot
- Private Indian space-tech companies (Skyroot Aerospace, Agnikul Cosmos, among others) are developing small-lift orbital vehicles to serve domestic and international small-satellite customers
- India's space economy is targeted for significant expansion under the Indian Space Policy 2023, with private investment expected to scale up launch cadence beyond what a single government agency can sustain
A successful Vikram-1 orbital flight would position Skyroot as a commercial launch service provider competing for small-satellite contracts in the same segment ISRO's SSLV addresses, diversifying India's national launch capacity.
