Reaching outward
from here.
An unofficial concept redesign of India's space programme site: launch vehicles, planetary probes, and Earth-observation systems behind weather, navigation, and communications.
Mission in focus
Gaganyaan
India's first crewed spaceflight programme: a three-person capsule qualified to carry Gaganyatris to low Earth orbit and return them safely.

Missions
In orbit, in transit, in build.
From a rocket carried on a bicycle to a lander at the lunar south pole: fifty years of hardware, organised so you can find the mission you came for.
2019Operational
Chandrayaan-2
Lunar OrbitIndia's second lunar mission. The lander was lost on descent in 2019, but the orbiter remains healthy and continues science from a 100 km polar orbit.
planetary2023CompletedChandrayaan-3
Lunar South Polar RegionThe soft landing that made India the fourth nation to reach the lunar surface, and the first to touch down near the Moon's south pole.
planetary2023OperationalAditya-L1
Sun-Earth Lagrange Point 1India's first solar observatory, parked 1.5 million kilometres sunward where it can watch the Sun without interruption.
science2025OperationalNISAR
Sun-Synchronous OrbitA joint NASA-ISRO radar satellite that maps the deformation of nearly all of Earth's land and ice every twelve days.
earth—OperationalNavIC
Regional Geosynchronous ConstellationIndia's regional navigation constellation (formerly IRNSS). Designed for seven spacecraft; as of mid-2026 only three provide full PNT, with replenishment underway.
navigation2013CompletedMars Orbiter Mission
Mars OrbitMangalyaan reached Mars on the first attempt, something no other space agency had managed, on a budget smaller than the film Gravity.

The fleet, side by side.
SSLV. PSLV. GSLV. LVM3. Four vehicles on one stage: a clear look at the hardware that puts Indian payloads on orbit.

- scienceFirst national workshop on microgravity research convenesResearchers gathered to shape India's microgravity experiment portfolio, building on results returned from the Axiom-4 mission.
Organisation
Centres, labs, and the commercial layer.
Fourteen centres build the hardware. Four autonomous bodies do the science. Two entities open the sector to industry.
