Liquid Propulsion Systems Centre Valiamala is ISRO's headquarters for liquid, cryogenic, and semi-cryogenic propulsion research, system engineering, and project management. The active operations campus admits advance-registered school and college groups on alternate Fridays, giving eligible students a rare structured visit to a working Indian space-propulsion center. Groups must contain 25 to 100 students, schools are limited to eighth standard and above, institutional authorization and original photo identification are required, and electronic devices are prohibited by the site's security rules. Visits therefore require formal planning and are not available for casual walk-ins.
