What is the name of the uncrewed orbital test flight that ISRO aims to launch in late March 2026 to support human exploration missions?

The uncrewed orbital test flight that the Indian Space Research Organisation (ISRO) is preparing to launch in late March 2026 to support its human exploration missions is named Gaganyaan-1. This mission represents a crucial step in India's ambitious human spaceflight program, aiming to validate the various systems and technologies required for future crewed flights. It will demonstrate the end-to-end mission sequence, including the aerodynamics of the human-rated launch vehicle, the operations of the orbital module, and the critical re-entry and recovery of the crew module.

A key component of the Gaganyaan-1 mission will be the half-humanoid robot named Vyommitra, which means "space friend" in Sanskrit. Vyommitra will be on board the crew module to simulate astronaut conditions and collect vital data on environmental parameters like temperature, pressure, and radiation. This data is essential for assessing the performance of life-support systems and ensuring the safety and well-being of human astronauts in subsequent missions. The flight will also test the crew escape mechanism and re-entry technologies, which are paramount for crew safety.

The Gaganyaan program as a whole is India's maiden human spaceflight initiative, with the ultimate goal of sending Indian astronauts to a low Earth orbit for a three-day mission and safely returning them. If successful, India will join an elite group of nations—the United States, Russia, and China—that have independently launched human spaceflight missions. This program is not only a testament to India's technological prowess but also a catalyst for innovation, boosting various industries and academic research, and inspiring future generations in science and technology. The success of these uncrewed test flights, including Gaganyaan-1, is foundational to India's long-term space aspirations, which also include establishing its own space station, the Bharatiya Antariksh Station, by 2035.
