C
In order to orbit, as well as a forward Vector , and object also needs to fall towards what it is Orbiting
The Craft is obiting, hence whatever is in it is Orbiting too
Unless there is a change of Vector
Just like if you are in a Car doing 60 mph, toss a tennis ball up straight, it will also come straight down

When the space shuttle is orbiting the earth, it is moving at a constant speed. At the position, there are two forces on space shuttle. They are the Universal gravitational force and the centripetal force. For the space shuttle to move at a constant speed, these two forces are equal in magnitude. When this happens, the astronauts are falling at the same rate as the space shuttle as it orbits around earth. So C is the correct answer.
