What was India's Gaganyaan G1 mission and why was it historic?

The answer

In March 2026, the Indian Space Research Organisation (ISRO) launched Gaganyaan G1 (also called Gaganyaan Uncrewed G1), the first uncrewed orbital test flight of India's indigenous human-rated spacecraft. The mission carried Vyommitra - a female half-humanoid robot developed by ISRO - designed to simulate human functions and test the spacecraft's life support systems, crew module, and re-entry protocols. Vyommitra can perform switch-panel operations, respond to crew communication, and monitor environmental conditions inside the capsule. The spacecraft was launched atop a human-rated LVM3 (formerly GSLV Mk III) rocket from Sriharikota and successfully orbited Earth before re-entering and splashing down in the Indian Ocean. The mission validated critical systems for India's future crewed Gaganyaan missions, making India one of only four nations (after Russia, the US, and China) to develop indigenous human spaceflight capability. The success followed ISRO's Chandrayaan-3 lunar landing achievement in August 2023.
