"Under the Gaganyaan schedule, three flights will be sent in orbit. Of the three, there will be two unmanned flights and one human spaceflight. The human spaceflight will take 16 minutes to reach the orbit where it will stay for five to seven days. After de-boost, the Orbital Module will take 36 minutes to splash down in Arabian Sea. The crew module will be recovered within 15-20 days," Sivan said.
