SOLAR SYSTEM

Detailed explanation-1: -The initial boost helps in cutting down the cost of rockets used to launch the satellites. This is the major reason for launching satellites in the east ward direction.

Detailed explanation-2: -Carrying a satellite to the fixed position in space, a great amount of energy is needed. To get much energy, we launch the rocket toward the east, which is the same direction of the Earth’s rotation.

Detailed explanation-3: -Our earth rotates from west to east. So, when a rocket is propelled from west to east in the equatorial plane, the rocket gets added advantage of earth’s rotational speed. A component of earth’s rotational speed adds up with the projection speed of the rocket.

Detailed explanation-4: -It doesn’t matter how big the horizontal velocity is on the earth’s surface; space rockets are always launched eastward.

Detailed explanation-5: -Vikram Sarabhai Space Centre, Thiruvananthapuram (Thumba), Kerala, Satish Dhawan Space Centre (Sriharikota) located in Andhra Pradesh, and Dr Abdul Kalam Island, which is located in Odisha, are the three rocket launching sites.

Detailed explanation-6: -The added velocity reduces the fuel needed to launch spacecraft to orbit. Since Earth rotates eastward, only launches eastward take advantage of this boost of speed. Westward launches, in fact, are especially difficult from the Equator because of the need to counteract the extra rotational speed.
