WebMar 15, 2024 · GPS keeps track of where the spacecraft are relative to Earth's surface, and onboard accelerometers record forces on the spacecraft other than gravity, such as atmospheric drag and solar radiation. Scientists process these data to produce monthly maps … WebBecause the Earth is not flat - it is round, and gravity holds the whole earth, and all on the surface, to as good a ball shape at it can get - including the surface of the water. Gravity works towards a centre of mass, but that’s downwards (everywhere) on this Earth. The Earth is not an exact ball.

Consider what would happen on Earth: The air bubble, lighter than water, would race upward to burst through the surface of the droplet. In space, the air bubble doesn't rise because it is no lighter than the water around it—there's no buoyancy. The droplet doesn't fall from the leaf ...
