Why are most of ISRO's satellite launch sites, like Satish Dhawan Space Centre in Sriharikota, located on the eastern coast near the equator?
  1. Eastern coast receives the least rainfall in India
  2. Earth's eastward rotation provides an extra initial speed boost to rockets launching eastward
  3. Equatorial ocean water is colder and cools the rocket boosters
  4. Magnetic field at the eastern coast pulls rockets upward

Solution

Launching eastward near the equator takes advantage of Earth's rotational speed, reducing the fuel needed to reach orbit.
