    An astronaut in the satellite releases a spoon out of satellite in the space. Will the spoon fall on the earth?

    This depends much on the state of the satellite. If the satellite is orbiting the earth then the spoon -as it is dropped from the satellite- will have sufficient velocity to stay also in orbit. Of course it depends also whether you are considering or not zero friction. If you consider realistic conditions in which there is a -minimal- friction also in outer space, then the spoon will slow down until it eventually falls on the earth. Anyway while falling through the atmosphere the friction will heat it up enough to melt it and destroy it, so it will not actually arrive on the earth surface...
