The three projects include 'PSLV Integration Facility' at Satish Dhawan Space Center in Sriharikota, 'Semi-Cryogenic Integrated Engine and Stage Test Facility' at ISRO Propulsion Facility in Mahendragiri, and 'Trisonic Wind Tunnel' at VSSC. It will be done.

He will also launch India's first indigenous green hydrogen fuel cell barge and reach out to thousands of MSME entrepreneurs active in the automobile sector in Madurai, the statement said.

His PSLV Integration Facility at the Satish Dhawan Space Center will help increase PSLV's launch frequency from six to 15 per year.
