Why is the moon's gravity differential field pointing away from the moon on the side of the Earth facing away from the moon?

The moon's gravity differential field points away from the Earth due to the influence of the Earth's gravitational pull. The moon's gravity is strongest on the side closest to the Earth and gradually decreases towards the side that is farthest away. This creates a differential force that pushes away from the Earth's center.
The moon's gravity differential field is responsible for creating the Earth's tides. The moon's gravity pulls on the Earth's oceans, causing them to bulge towards the moon. As the Earth rotates, this bulge moves around the planet, creating high and low tides.
The moon's gravity differential field is stronger on the side facing away from the Earth because it is the side closest to the moon. The closer an object is to a massive body, the stronger the gravitational pull. Therefore, the side of the moon facing away from the Earth experiences a stronger pull from the moon's gravity.
Yes, the moon's gravity differential field does affect the Earth's rotation. The Earth's rotation is gradually slowing down due to the tidal forces created by the moon's gravity. This causes the Earth's rotation to slow by about 1.4 milliseconds per century.
The moon's gravity differential field can impact space missions by affecting the trajectory and speed of spacecraft. The differential force can cause changes in the spacecraft's orbit and may require additional fuel to make course corrections. However, the moon's gravity also provides a helpful slingshot effect for spacecraft, allowing them to conserve fuel and travel farther in the solar system.
