New Delhi: The Indian Space Research Organisation (ISRO) has taken a significant leap in India’s human spaceflight journey by setting up a dedicated Orbital Module Preparation Facility (OMPF) at its Satish Dhawan Space Centre (SDSC) in Sriharikota, Andhra Pradesh.
This new facility strengthens infrastructure for the Gaganyaan Mission, which aims to make India one of the few nations capable of independently sending humans into space.
The Orbital Module Facility will ensure meticulous assembly, testing and integration of mission-critical components such as the Crew Module and Service Module, laying solid groundwork for India’s first crewed spaceflight.
What Is the ISRO Orbital Module Preparation Facility
The newly established OMPF is a state-of-the-art centre at SDSC Sriharikota designed to support:
- Integration and testing of the Orbital Module, which houses the Crew Module and Service Module.
- Precision preparation of flight components before stacking onto the Human-Rated Launch Vehicle Mark-3 (HLVM3).
- Ensuring quality checks and safety verification following stringent requirements for crewed missions.

This facility is a critical addition to ground infrastructure tailored specifically for the Gaganyaan programme.
Infrastructure Upgrades Supporting Human Spaceflight
Alongside the OMPF, ISRO has upgraded and established multiple mission support systems:
Gaganyaan Control Centre
A dedicated control hub for mission operations to monitor flight progress, telemetry data, and execute command sequences in real time.
Crew Training Facility (Bangalore)
Astronauts—referred to as Gaganyatris—undergo extensive physical, psychological, and technical training here. Training includes simulations, flight protocols, emergency procedures, and microgravity preparedness.
Second Launch Pad Enhancements at Sriharikota
Upgrades ensure the launch infrastructure meets human-rating requirements, incorporating safety systems such as the Launch Escape System for crew safety.
How the ISRO Orbital Module Facility Strengthens Gaganyaan Readiness
Here is how ISRO orbital module facility;
Crew Module Preparation
The Crew Module is the living and operational space for astronauts during their orbital flight.
The OMPF allows:
- Integration of life-support systems
- Environmental control systems testing
- Pressure and safety integrity checks
Service Module Validation
The Service Module supplies propulsion, electrical power, and thermal control. Its systems underwent rigorous hot-fire tests at the ISRO Propulsion Complex in Mahendragiri, validating real-world performance under launch stress scenarios.
What is Gaganyaan Mission
The Gaganyaan programme represents India’s flagship human spaceflight initiative led by ISRO.
Its key objectives and structure include:
- Launching a crew of up to three astronauts into Low Earth Orbit (~400 km) for a multi-day mission.
- Completing multiple uncrewed test flights (e.g., Gaganyaan-1, Gaganyaan-2) before the final crewed mission.
- Using the Human-Rated Launch Vehicle Mark-3 (HLVM3), specifically modified for carrying humans.
The first uncrewed test missions are expected as early as 2026, followed by a crewed flight planned for 2027, contingent on successful testing and safety validations.
Importance of the Orbital Module Facility in Human Spaceflight
This facility is not just another assembly hall — it is the nerve centre for crew safety and mission success.
It allows engineers to:
- Validate the Crew Module readiness under controlled conditions
- Integrate vital systems like life-support and navigation
- Execute complex tests before the spacecraft is finally stacked for launch
By institutionalising this capability on Indian soil, ISRO cements its commitment to safe, reliable, and indigenous human spaceflight.
Significance of ISRO Orbital Module Facility
With the Orbital Module Facility and other ground infrastructure upgrades in place:
- India strengthens its position among countries capable of human spaceflight.
- The platform boosts domestic aerospace manufacturing and high-precision systems engineering.
- It supports future ambitions such as India’s proposed Bharatiya Antariksh Station (orbital space station) targeted for the late 2020s–2030s.
