HLVM3 is India’s first human-rated launch vehicle, adapted from the proven LVM3 (GSLV Mk III) platform to safely carry astronauts (Gaganyatris) to Low Earth Orbit (LEO) under the Gaganyaan Mission.

Developed By

• Indian Space Research Organisation (ISRO)
• Guided by the Human Space Flight Centre (HSFC)

Mission Objectives

• Safely launch, place in orbit, and return Indian astronauts.
• Serve as the launch vehicle for future missions, including the Bharatiya Antariksha Station and Indian crewed lunar missions.
• Strengthen India’s self-reliance in human spaceflight through advanced safety systems.

Key Features

• Three-stage configuration: Two S200 solid boosters, L110 liquid core stage, and C25 cryogenic upper stage.
• Payload Capacity: About 10 tonnes to Low Earth Orbit (LEO).
• Human-rated design: Enhanced redundancy, fault tolerance, higher safety margins, and stringent quality assurance.
• Crew Escape System (CES): Five motors tested; enables emergency crew escape from liftoff until orbital insertion.
• Crew Module (CM): Validated for atmospheric re-entry, thermal protection, and parachute-assisted landing.
• Service Module (SM): Provides propulsion, power supply, and life-support/environmental control.
• Supporting Infrastructure: Dedicated launch facilities at SDSC, Gaganyaan Control Centre, astronaut training facilities, and recovery & communication network.
