India is entering a transformative new chapter in space exploration, with ISRO preparing for human spaceflight, planetary missions, and next-generation launch technologies that the government says will position the country as a leading global space power. An official government fact-sheet, released on 23 August, outlines a sweeping roadmap spanning the Gaganyaan crewed mission, a Venus Orbiter, a national space station, and fully reusable rockets.

Gaganyaan: India's crewed spaceflight mission

The Gaganyaan human spaceflight programme, first approved in January 2019, was significantly expanded in September 2024 to a total outlay of ₹20,193 crore, covering 8 missions in all — including precursor flights for the Bharatiya Antariksh Station (BAS-01). The programme aims to send a crew of three Indian astronauts to a 400-km orbit for a three-day mission.

The first uncrewed experimental flight — which will validate critical technologies including the Vyommitra half-humanoid robot — is targeted for Q4 of 2026. The crewed mission itself is slated for 2027, according to the fact-sheet.

Bharatiya Antariksh Station: India's own space station by 2035

India's planned five-module Bharatiya Antariksh Station (BAS) is targeted for full operationalisation by 2035. The first module, BAS-01, is planned for launch by 2028. The station is designed to support long-duration human spaceflight, microgravity research, and advanced orbital operations.

Notably, SPADEX-2 and SPADEX-3 missions are being studied to advance orbital docking capabilities essential for future Chandrayaan-4, Gaganyaan, and BAS missions. These missions will demonstrate spacecraft docking, sample and crew transfer, and propellant transfer in orbit.

Venus Orbiter Mission and deep-space ambitions

Targeted for launch in March 2028, the Venus Orbiter Mission will study the planet's geology, atmosphere, and ionosphere. The mission will also demonstrate advanced aerobraking and thermal-management technologies — capabilities critical for future deep-space exploration. This makes India only the fourth space agency to attempt a dedicated Venus mission.

Next-generation launch vehicles and reusability

ISRO is developing a 200-tonne thrust semi-cryogenic engine to power more capable launch vehicles with higher payload capacity. A semi-cryogenic booster stage is also being developed for the Launch Vehicle Mark-3 (LVM3), significantly enhancing its payload-carrying capability.

In parallel, ISRO is demonstrating booster recovery through Vertical Take-off and Vertical Landing (VTVL) technology — a step toward rocket-stage reusability and lower launch costs. The agency is also developing a partially reusable Next Generation Launch Vehicle (NGLV) using LOX-Methane propulsion for frequent, cost-effective launches.

Rounding out the roadmap, ISRO is building a Winged Orbital Re-entry Vehicle under its Reusable Launch Vehicle (RLV) programme to demonstrate orbital re-entry and runway landing, alongside an air-breathing propulsion technology demonstrator for more efficient atmospheric flight. Together, these programmes mark India's most ambitious push yet to reduce the cost of access to space and sustain a long-term human presence beyond Earth.
