When we lauch a space shuttle will it go with Earths rotationor would it go opposite?
When a space shuttle is launched, it generally follows the rotation of the Earth in the same direction. This is because the Earth's rotation imparts momentum to objects on its surface, including the atmosphere and everything within it. So, for efficiency, space agencies like NASA typically launch shuttles in the same direction as the Earth's rotation.
To better understand why this is done, let me explain a bit about the physics involved. The Earth rotates from west to east, which means that objects on the surface, including the atmosphere, are also moving in the same direction, albeit at much slower speeds compared to the Earth's rotation.
When a space shuttle is launched, it needs to reach a certain velocity, called orbital velocity, to overcome the gravitational pull of the Earth and enter into orbit. By launching in the direction of the Earth's rotation, the shuttle gains an additional speed boost due to the Earth's rotation, which helps it achieve the necessary orbital velocity more easily and efficiently.
This strategy saves fuel and allows for increased payload capacity, as the shuttle takes advantage of the Earth's rotation to gain energy. Moreover, launching in the same direction as the Earth's rotation also helps in avoiding collisions with other satellites in space that are already moving in that direction.
However, it's worth noting that there might be specific reasons to launch in the opposite direction of the Earth's rotation. For instance, some polar orbiting satellites are intentionally launched against the Earth's rotation to achieve a specific orbit that covers the poles. But for most space shuttle launches, going with the Earth's rotation is the preferred approach due to its operational and efficiency advantages.
