Why is this in the news?

On 6 August 2026, Dr. Jitendra Singh, Union Minister of State (Independent Charge) for Science & Technology, Earth Sciences, and Space, informed the Rajya Sabha about the significant progress of India’s maiden human spaceflight mission, Gaganyaan. He highlighted key achievements in human-rating systems, infrastructure development, and the roadmap for India’s long-term human space exploration, including the planned launch of the Vyommitra mission in late 2026 and the establishment of the Indian Space Station by 2035. This briefing underscores India’s strategic shift from robotic to crewed space missions and its ambition to join the elite group of spacefaring nations.

Background

• The Gaganyaan mission, announced in 2018 by Prime Minister Narendra Modi, is India’s first indigenous human spaceflight programme, aimed at demonstrating the capability to send humans to Low Earth Orbit (LEO) and safely return them to Earth.
• The mission is a critical milestone in India’s space ambitions, following the success of Chandrayaan and Mangalyaan missions, and aligns with the vision of an Atmanirbhar Bharat in space technology.
• India’s space programme has evolved from launching satellites to achieving complex missions like the Mars Orbiter Mission (2014) and the Chandrayaan-2 lunar mission (2019), which included an orbiter, lander, and rover.
• The Gaganyaan mission is part of a broader strategy to establish India as a self-reliant space power, with long-term goals including the development of an Indian Space Station (BAS) by 2035 and potential lunar and interplanetary missions.
• International collaborations, such as those with the European Space Agency (ESA) for network operations and the Australian Space Agency (ASA) for crew recovery, highlight India’s integration into the global space community.

What is the Gaganyaan Mission and India’s Human Spaceflight Roadmap?

• Gaganyaan is India’s first indigenous human spaceflight mission, designed to send a crew of three astronauts to a Low Earth Orbit (LEO) of 400 km for a duration of up to seven days and return them safely to Earth.
• The mission is a technological demonstration of India’s capability to conduct crewed space missions, including human-rated launch vehicles, life support systems, and crew escape mechanisms.
• The Human-rated Launch Vehicle Mark-3 (HLVM3) is the designated launch vehicle for the Gaganyaan mission, with all propulsion stages and structural components undergoing rigorous ground testing and qualification.
• The Crew Module (CM) and Service Module (SM) form the orbital module, housing the crew during the mission. The CM is designed to re-enter Earth’s atmosphere and land safely, while the SM provides propulsion and support systems.
• The Environmental Control and Life Support System (ECLSS) is critical for maintaining a habitable environment inside the crew module, regulating oxygen, carbon dioxide, temperature, and humidity levels.
• The Crew Escape System (CES) is a fail-safe mechanism designed to separate the crew module from the launch vehicle in case of an anomaly, ensuring the safety of the astronauts by deploying parachutes for a controlled descent and landing.
• Vyommitra, a half-humanoid robot, will be launched in the first uncrewed mission (scheduled for Q4 2026) to test the Gaganyaan systems, including ECLSS, thermal protection, and deceleration systems, prior to human missions.
• The Indian Space Station (BAS) is envisaged as a modular space station with five modules, serving as a platform for scientific research, technology demonstration, and international collaboration in space exploration.
