Scientific Research: To conduct experiments in microgravity, which could lead to breakthroughs in various scientific fields.
Technological Advancement: Pushing the boundaries of aerospace technology, particularly in life support, propulsion, and spacecraft engineering.
Inspiration and Education: To inspire young minds towards STEM careers and to educate the public about space science.

The Gaganyaan Mission

Gaganyaan, translating to “Sky Craft,” is the centerpiece of India’s human spaceflight initiative. Announced in 2018 by Prime Minister Narendra Modi, the mission aims to send a crew of three astronauts to an orbit of approximately 400 km for a duration of 5-7 days.

Technical Specifications

Crew Module: Designed to accommodate the astronauts, this module includes life support systems, navigational equipment, and communication tools. It has been engineered to be reusable, capable of surviving the harsh re-entry into Earth’s atmosphere.
Service Module: This module provides the spacecraft with power, propulsion, and thermal control systems necessary for maintaining orbit and managing the spacecraft’s environment.
Escape System: A critical safety feature, this system is designed to quickly detach the crew module from the launch vehicle in case of an emergency during the ascent phase.

The spacecraft will be launched using the LVM3 rocket, previously known as GSLV Mk III, which has undergone modifications to meet the stringent safety standards required for human-rating. This involves extensive testing for reliability, redundancy, and safety.

Crew Preparation

The astronauts, known as “vyomanauts,” are predominantly from the Indian Air Force, selected for their exceptional physical and mental aptitude. Their training has been specialized to include:

Physical Conditioning: To withstand the rigors of space travel, including zero-gravity environments.
Space Medicine: Understanding the effects of space on the human body, including radiation and microgravity.
Survival Training: For scenarios where the spacecraft might land in remote or harsh environments.
Spacecraft Operations: Learning to operate the spacecraft’s systems, both in normal and emergency conditions.

Training has been a blend of domestic and international efforts, with significant sessions held at Russia’s Gagarin Cosmonaut Training Center.

Technological Challenges and Innovations

Achieving human spaceflight involves surmounting numerous technical challenges:

Life Support Systems: ISRO has developed systems to recycle air, manage water, and handle waste in the confined space environment, ensuring astronaut survival in space.
Radiation Protection: Given the harmful radiation in space, ISRO has focused on developing shielding materials and monitoring systems to safeguard the crew.
Re-entry and Recovery: The spacecraft must survive the intense heat and deceleration forces during re-entry. ISRO has worked on advanced thermal protection systems and parachutes for a safe splashdown.
Human-Rating: Every component and system must be rigorously tested to ensure it can support human life, a process far more stringent than for unmanned missions.

International Collaboration

ISRO’s approach to human spaceflight has not been isolationist. Key partnerships include:

Russia: Offering training facilities and expertise in astronaut preparation and spacecraft design.
US: Through agreements like the Artemis Accords, there’s potential for future collaborations, including sharing technology and knowledge.
