Gaganyaan Mission: Launch Date, Members, Objectives, UPSC Notes

India is making remarkable progress in space exploration. The Gaganyaan Mission is a major initiative that aims to send Indian astronauts into space. At the same time, the Indian government is introducing reforms such as One Nation One Election UPSC, which seeks to improve the election process. The Gaganyaan Mission UPSC is a significant step in India's space journey. It will demonstrate the country’s capability to conduct human spaceflight. This ambitious project is undertaken by the Indian Space Research Organisation (ISRO) and is expected to elevate India’s status in global space research.

What is Gaganyaan Mission?

The Gaganyaan Mission is India's first human spaceflight program, developed by ISRO. The project aims to send three Indian astronauts, also known as Gaganyaan Mission Astronauts, into low Earth orbit (LEO). The mission intends to keep the crew in space for up to three days before safely bringing them back to Earth. The primary goal is to develop the capability for human space travel, an essential milestone for future deep-space exploration.

The Gaganyaan Mission Launch Date is planned based on the success of test missions. ISRO has scheduled the Gaganyaan 1 Launch Date before the final crewed mission. The final date will be confirmed after all safety tests are completed.

The Gaganyaan Mission requires advanced technologies to ensure astronaut safety and mission success. Key technologies include:

Human-Rated LVM3

The Gaganyaan Mission Launch Vehicle is a modified version of ISRO’s LVM3 rocket, also known as the GSLV Mk III. It has been upgraded to handle human spaceflight by ensuring maximum reliability and safety. It can carry a crew module with astronauts to low Earth orbit and return them safely to Earth.

Orbital Module (OM)

The Orbital Module (OM) comprises two sections: the Crew Module (CM), which houses astronauts, and the Service Module (SM), which provides power and propulsion. The module is designed to maintain life-support conditions in space, making it habitable for the Gaganyaan Crew throughout the mission.

Crew Escape System

The Crew Escape System is a safety mechanism that allows astronauts to be quickly ejected from the launch vehicle in case of failure. This system will ensure the survival of the Gaganyaan Mission Astronauts by detaching the crew module from the rocket and deploying parachutes for a safe landing.

Life Support System

The Life Support System maintains a breathable atmosphere inside the spacecraft. It regulates oxygen levels, temperature, humidity, and pressure while filtering out carbon dioxide. This system is vital for sustaining astronaut life during the mission, enabling them to perform their tasks without health risks.

Navigation and Communication Systems

These systems enable real-time communication between the spacecraft and mission control on Earth. The navigation system ensures precise movement in space, while the communication system provides continuous contact with the ground station. This allows mission controllers to monitor astronaut health and spacecraft conditions at all times.

Orbital Module (OM)

The Orbital Module (OM) is an essential component of the Gaganyaan Mission. It serves as the primary spacecraft structure that supports astronaut activities and mission operations. The module is designed to provide life-supporting conditions while orbiting Earth.

Crew Module (CM)

The Crew Module is a secure, pressurized section where astronauts will live and work during the mission. It provides oxygen, temperature regulation, and waste management facilities, ensuring a safe environment for the Gaganyaan Crew while they are in space.

Service Module (SM)

The Service Module supports essential spacecraft functions, including propulsion, power generation, and thermal control. It houses solar panels, batteries, and thrusters required for navigation. This module ensures the proper functioning of the Orbital Module (OM) throughout the mission duration.

Thermal Protection System

The Thermal Protection System is designed to shield the Crew Module (CM) from extreme temperatures during re-entry into Earth’s atmosphere. This system prevents overheating and ensures that the spacecraft structure remains intact when returning to the surface.

Radiation Shielding

The Orbital Module (OM) incorporates advanced radiation shielding to protect astronauts from harmful space radiation. This is crucial for long-duration space missions, as exposure to cosmic rays and solar radiation can affect astronaut health.

Autonomous Flight Systems

The Orbital Module (OM) is equipped with autonomous flight control systems that allow it to operate with minimal ground intervention. These systems ensure precise navigation and docking capabilities, increasing mission reliability.

The training for the India Manned Space Mission is intensive. The selected astronauts, whose Gaganyaan Astronauts Name list includes four Indian Air Force pilots, are undergoing training in India and Russia. Their training covers:

• Spacecraft operations and controls.
• Survival techniques in case of emergency landings.
• Adaptation to zero-gravity conditions.
• Handling spacecraft systems and mission protocols.
• Physical and mental endurance training.

Different Phases of Gaganyaan Mission

The Gaganyaan Mission is planned in multiple phases to ensure safety and mission success. It includes rigorous testing, unmanned test flights, and finally, the manned mission. These phases will validate the spacecraft’s performance, ensuring that the systems are fully operational before Indian astronauts embark on their journey into space.

Unmanned Test Flight (Gaganyaan-1)

The first phase includes an unmanned test flight using a prototype of the Orbital Module (OM). This test will evaluate the spacecraft’s safety systems, launch vehicle, and re-entry capabilities before sending humans into space.

Second Unmanned Test Flight

The second test flight will further validate the crew module’s functionality. It will test Life Support Systems, navigation, and emergency procedures. It will also carry a humanoid robot to simulate human conditions in space.

Pad Abort Test

A crucial phase will involve testing the Crew Escape System, ensuring that astronauts can be quickly ejected from the launch vehicle in case of a failure. This test will confirm the system’s reliability for emergency evacuation.

Human-Rated LVM3 Qualification

The Gaganyaan Mission Launch Vehicle, LVM3, will undergo rigorous tests to be certified as human-rated. It will be assessed for safety, precision, and endurance before carrying Indian astronauts into space.

Final Crewed Gaganyaan Mission

After successful unmanned missions, the final phase will involve launching three astronauts into low Earth orbit for three days. The Gaganyaan Crew will conduct experiments, test survival systems, and experience microgravity before returning safely to Earth.

Re-Entry and Splashdown

The crew module will re-enter Earth's atmosphere at high speed, using a Thermal Protection System to withstand extreme temperatures. Parachutes will slow down the descent, leading to a controlled splashdown in the Indian Ocean, where astronauts will be recovered.
