The space shuttle orbits about 200km above the earths surface. The shuttle's "pre-launch weight" is its weight measured on the ground. (Neglecting the fuel) The magnitude of the force of gravity on the shuttle while it is in orbit is

GREEN: Slightly greater than pre-launch.

YELLOW: Equal to pre-launch

BLUE: Slightly less than pre-launch

PURPLE: Lots less than pre-launch, but not zero

GREEN: Zero.
