Because those pictures are taken in daylight, with the bright Sun lighting up the space craft, ground, astronauts, and everything except the sky. The sky is only black because there is no air to scatter the sunlight. And the stars are not bright enough to record on the film with a normal exposure. For the same reason you will see no stars in the black sky in photographs taken at a night football game. The stadium lights light up the field brightly so that you can take the picture with a 1/500 second exposure or some small fraction of a second. But it takes a very slow shutter speed, more that a second long, maybe several seconds, to record the stars. If you took such an exposure the field and players would be totally over exposed.

To correctly expose the Earth, the stars will be underexposed.
