Because a freely falling object has gravity acting upon it and causing an acceleration. In an atmosphere, a freely falling object may reach its terminal velocity - a maximum velocity of descent caused by the resistance/frictional effects of the atmosphere. In this case the object does fall at a constant speed. Thanks from topsquark and Elize

Yes. The acceleration of the spacecraft is equal to g at that height.
