Explanation

Thumba in Kerala was chosen for India's first rocket launch station in 1963 primarily because of its unique geographic advantages. It is very close to the sea in the East, West, and South directions, which is crucial for safe rocket launches and trajectory clearance. While being near the magnetic equator is also beneficial, the immediate practical necessity was the sea access for launch safety.
