why space rockets are launched from west to eat
Answers
Answer:
✨Since the earth revolves from West to East around sun , so when rocket is launched from West to East , the relative velocity of rocket = launching velocity of rocket + linear velocity of Earth.✨
⚫Thus the velocity of rocket increases which helps it to rise without much consumption of fuel . Also the linear velocity of Earth is more in equatorial plane.⚫
Answer:
flying east means you get a free boost from the Earth’s rotation, because you're already rotating in that direction. How much of a boost depends in the inclination of your orbit. Orbits can be polar (zipping up to the earth’s poles and back again)— equatorial (following the earths equator)— or anywhere in between. The boost from the earths rotation is in the plane of the equator, so it helps with equatorial orbits in particular.
The orbit you choose depends on the purpose of your satellite. Some satellites go into geosynchronous orbits, sitting over the same point on earth all the time. These orbits are all equatorial, and all at the same altitude. So a west-flying (retrograde) satellite in this orbit would be a disaster, flying at a relative speed of 36,000 mph directly through that crowded space. All of these satellites fly east. Other satellites want to be sun-synchronous — basically, wherever they are, it's always the same time of day. These are nearly polar orbits, and they are actually slightly retrograde. They all have to fly west, a little bit.
Other orbits are usually launched east to take advantage of the boost from the earth’s rotation, but the closer to polar you get, the less you care. Near-Polar (high inclination) satellites are mostly earth observing or specialized low earth orbit communication satellites which need to see higher latitudes, or spy satellites.
The other reason to launch retrograde is because you don't want to launch over populated areas. So, for example, Israel generally launches west to avoid looking like they are attacking unfriendly neighbors to the east.
