ISRO's Ambitious Launch Plans

The Indian Space Research Organisation (ISRO) has announced plans for an impressive total of seven space launch missions by March 2026. This marks a significant phase for India's space agency, highlighting its commitment to advancing both national and global space capabilities. Among these missions is the much-anticipated Gaganyaan unmanned mission, part of the human space flight initiative. This comprehensive launch schedule showcases ISRO's dual objectives: conducting strategic national missions while contributing to the global space economy.

Details of the Launch Announcements

ISRO's schedule includes seven launches within a condensed timeline, with the initial mission set to take place as early as next week. These missions will utilize various launch vehicles, such as LVM3, PSLV, GSLV Mk II, and SSLV. The primary goals of these missions encompass communication, earth observation, navigation, technology demonstration, and human spaceflight.

1. Gaganyaan Uncrewed Mission

The Gaganyaan uncrewed mission represents the first step in India's human spaceflight program, featuring the robot Vyommitra onboard. The objectives of this mission include:

  • Testing aerodynamics and the performance of human-rated launch vehicles.
  • Demonstrating the operations of the orbital module.
  • Validating the re-entry and recovery systems of the crew module.

Furthermore, a second uncrewed mission is scheduled before the first Indian astronaut flight, anticipated in 2027.

2. Electric Propulsion and Quantum Key Distribution

The PSLV-C63 mission aims to carry TDS-01, showcasing several critical technologies:

  • High Thrust Electric Propulsion System: This innovative system reduces satellite fuel usage from over 2 tonnes to approximately 200 kg, ensuring lighter and more efficient satellites.
  • Quantum Key Distribution (QKD): This technology facilitates advancements in secure communication.
  • Indigenous Travelling Wave Tube (TWT) Amplifier: This development promotes self-reliance in essential satellite transponder technologies.

3. Communication and Earth Observation Satellites

The upcoming LVM3-M5 mission will launch Bluebird-6 for AST Spacemobile in the U.S. under a commercial contract with NSIL. Additionally, the GSLV-Mk II will deploy EOS-5/GISAT-1A, which replaces the previously failed GISAT-1 mission from 2021. PSLV missions are also set to launch several satellites, including:

  • Oceansat
  • An Indo-Mauritius joint satellite
  • LEAP-2 satellite from Dhruva Space
  • EOS-N1 for strategic applications, along with 18 smaller satellites.

Moreover, a dedicated small satellite launch is planned via the SSLV mission before March 2026.

4. Commercialisation and Industry Participation

In a significant step towards enhancing India’s commercial launch capabilities, the NSIL-HAL-L&T consortium will manufacture five PSLV rockets. This initiative emphasizes technology transfer and encourages private-sector engagement, leading to cost-effective and frequent satellite launches.
