  • Gynoid (female robot) Vyommitra will undertake the first uncrewed mission of Gaganyaan. 

About Gaganyaan Mission

  • Objectives: Demonstrate India’s human spaceflight capability by launching crew of 3 members to an orbit of 400 km (Low Earth Orbit) for a 3 days mission and bring them back safely to earth, by landing in Indian sea waters.
