New Delhi: The Indian Space Research Organisation (ISRO) is gearing up for an unprecedented launch blitz, with seven missions scheduled by March next year, including the first uncrewed flight of the ambitious Gaganyaan human spaceflight programme and a landmark technology mission testing indigenous electric propulsion and quantum communication systems.

The packed launch calendar, reported by the Indian media on December 14, 2025, signals a decisive phase for India’s space programme as it balances strategic goals with an expanding commercial footprint.

The first launch in this series could take place as early as next week, setting the tone for one of ISRO’s busiest operational windows in recent years.

At the core of this schedule is the LVM3, India’s heaviest and most powerful rocket, which will be deployed for both commercial satellite launches and critical national missions.

Under a commercial contract managed by New Space India Limited (NSIL), the LVM3 will place the Bluebird-6 communication satellite of US-based AST SpaceMobile into orbit.

Union Minister of State for Space Jitendra Singh told Parliament last week that the mission highlights ISRO’s growing credibility as a global launch service provider, particularly for heavy satellites, at a time when international launch capacity is under strain.

Beyond commercial launches, the LVM3 is central to India’s long-term human spaceflight ambitions.

Early next year, the human-rated rocket will carry the first uncrewed Gaganyaan mission, with the humanoid robot Vyommitra onboard the crew module.

This mission will simulate an entire human spaceflight profile, from launch and orbital operations to atmospheric re-entry and recovery at sea.

According to Singh, the flight will validate end-to-end mission capabilities, including aerodynamic performance of the human-rated launch vehicle, mission operations of the orbital module, and safe recovery of the crew module.

Another uncrewed Gaganyaan mission is planned later next year, ahead of India’s target of sending astronauts into low Earth orbit by 2027.

ISRO’s upcoming launch manifest also reflects a structural shift towards deeper private sector involvement.

Next year will mark the launch of India’s first industry-built Polar Satellite Launch Vehicle (PSLV).

This rocket will deploy the Oceansat satellite and also carry the India-Mauritius Joint Satellite along with the LEAP-2 satellite developed by space startup Dhruva Space.

This milestone follows a technology transfer agreement signed in September, under which NSIL awarded a contract to a consortium led by Hindustan Aeronautics Limited (HAL) and Larsen & Toubro to manufacture five PSLV rockets.

The initiative is aimed at increasing launch frequency, strengthening India’s private space ecosystem, and easing pressure on ISRO’s in-house production lines.

ISRO will continue to use its own PSLVs for sensitive missions. One such launch will place the EOS-N1 earth observation satellite for a strategic user into orbit, alongside 18 smaller satellites from Indian and international customers.

Another mission using the GSLV Mk II will launch EOS-5, also known as GISAT-1A, replacing GISAT-1, which failed to reach its intended orbit in 2021.

A key technological highlight in the launch lineup is the PSLV-C63 mission carrying the Technology Demonstration Satellite-01 (TDS-01).

This satellite will test a high-thrust electric propulsion system, quantum key distribution technology, and an indigenous travelling wave tube amplifier.

The electric propulsion test could be a game-changer for ISRO’s future satellites.

Officials note that a conventional four-tonne communication satellite typically carries more than two tonnes of liquid fuel, while an electric propulsion-based satellite would need only about 200 kg.

This drastic reduction in mass can lower launch costs, improve payload efficiency, and allow more flexible mission planning without compromising performance.

The TDS-01 mission will also validate indigenous travelling wave tube amplifiers, a critical component of satellite transponders, boosting India’s self-reliance in satellite communication technologies with both civilian and strategic significance.

Rounding out the launch schedule is the Small Satellite Launch Vehicle (SSLV), with ISRO planning a dedicated satellite mission before March 2026.

Designed for rapid and cost-effective launches of small payloads, the SSLV adds another competitive option to India’s growing launch portfolio as ISRO enters a high-tempo, high-stakes phase of space activity.
