Gaganyaan Mission: India’s First Human Space Flight Program

The Gaganyaan Mission is a landmark initiative by the Indian Space Research Organisation (ISRO) aimed at demonstrating India’s capability to undertake human spaceflight. The mission, which is scheduled to launch in 2025, will send a three-member crew to a low Earth orbit (LEO) for a period of up to seven days.

Story Behind Word ‘Gaganayan’

India often chooses cool names for its space missions, either inspired by historical moments or digging deep into the ancient language of Sanskrit. “Gaganayaan” falls in the second category, translating to “Celestial Vehicle” – pretty cool, right?

Gaganyaan

Gagana (Sanskrit: गगन) – Means “sky,” “celestial,” or “atmosphere.”
Yāna (Sanskrit: यान) – Means “vehicle,” “craft,” or “vessel.”
Together, the word “Gaganyaan” translates to “sky vehicle” or “celestial craft.”

Gaganyaan: India’s Space Mission

Gaganyaan is India’s first crewed orbital spacecraft project. It’s a major milestone for the Indian Space Research Organisation (ISRO). The key goals of the Gaganyaan mission are:

Demonstrate India’s ability to send humans to Low Earth Orbit (LEO).
Lay a strong foundation for future, more ambitious, sustained human space exploration programs.

Philosophy Behind word ‘Gaganayan’

While there isn’t an officially stated “philosophy” behind the name “Gaganayaan,” we can infer some possible ideas based on its meaning and India’s approach to naming space missions:

1. Connection to the Universe: Choosing a Sanskrit word with roots in “sky” and “vehicle” suggests an intent to connect the mission to the vastness of the universe. It reflects India’s aspirations in space exploration and its desire to reach new heights.

2. Continuity with Tradition: India often names its space missions after mythological figures, historical events, or significant scientific discoveries. “Gaganayaan” continues this tradition of drawing inspiration from its rich heritage.

3. Simple and Evocative: The name is short, easy to pronounce, and carries a powerful image. This accessibility resonates with the public and creates a sense of national pride associated with the mission.

4. Reflecting India’s Identity: Choosing a Sanskrit word connects the mission to India’s ancient culture and intellectual tradition. It sends a message of cultural pride and demonstrates India’s contribution to the global scientific endeavor.

Gaganyaan Project

The Gaganyaan project aims to showcase India’s capability in human spaceflight by sending a three-member crew to a 400 km orbit for a three-day mission, followed by a safe return to Earth, landing in the waters off the coast of India.

This ambitious endeavor is realized through a carefully crafted strategy that leverages the domestic expertise and experience of the Indian industry, the intellectual prowess of India’s academic and research institutions, and the most advanced technologies from international partners. Essential to the Gaganyaan mission are the development of several critical technologies, including a human-rated launch vehicle to safely transport the crew into space, a Life Support System to maintain Earth-like conditions for the crew in orbit, provisions for crew emergency escape, and comprehensive crew management plans covering training, recovery, and rehabilitation.

To ensure the mission’s success, a series of precursor missions are set to demonstrate the readiness of these technologies. These preliminary missions encompass the Integrated Air Drop Test (IADT), the Pad Abort Test (PAT), and Test Vehicle (TV) flights. The safety and reliability of all systems will be thoroughly verified through unmanned missions before proceeding with the manned mission.

Human rated LVM3 – HLVM3

The LVM3 rocket, ISRO’s trusted and proven heavy-lift launcher, has been selected for the Gaganyaan mission. This rocket features a combination of solid, liquid, and cryogenic stages. To fulfill the stringent requirements of human spaceflight, all systems within the LVM3 have been adapted and upgraded, resulting in the Human Rated LVM3 (HLVM3). This enhanced version of the rocket is designed to carry the Orbital Module into a targeted Low Earth Orbit at 400 km.

The HLVM3 is equipped with a Crew Escape System (CES), which is powered by a series of rapid-activation, high burn rate solid motors. This system is designed to ensure the Crew Module, along with its occupants, is quickly moved to a safe distance from any potential dangers that could arise either on the launch pad or during the rocket’s ascent.

Orbital Module

The Orbital Module (OM) intended for Earth orbit is composed of a Crew Module (CM) and a Service Module (SM). The OM is furnished with advanced avionics systems, incorporating sufficient redundancy to prioritize human safety.

The CM serves as a habitable space in space for the crew, creating an Earth-like environment. It features a double-walled construction, consisting of a pressurized metallic Inner Structure and an unpressurized External Structure equipped with a Thermal Protection System (TPS). Within the CM, crucial components such as crew interfaces, human-centric products, life support systems, avionics, and deceleration systems are housed. Additionally, it is designed for re-entry to ensure the safety of the crew during descent until touchdown.

The SM is dedicated to providing essential support to the CM while in orbit. This unpressurized structure incorporates a thermal system, propulsion system, power systems, avionics systems, and deployment mechanisms. The SM plays a crucial role in maintaining the functionality and support required for the successful operation of the entire Orbital Module.
