BENGALURU: The first test vehicle mission of India’s ambitious maiden human spaceflight venture Gaganyaan to validate the crew escape system will be launched in a month or two, a key ISRO official said on Friday.

According to officials of the Bengaluru-headquartered national space agency, it would be the first of the four abort missions of the Gaganyaan programme. The first test vehicle mission, TV-D1, would be followed by the second test vehicle TV-D2 mission and the first uncrewed mission of Gaganyaan (LVM3-G1).
