NASA have not said they have NEW film, but they have newly restored and enhanced film
Of course they landed on the moon how else did the set up the The Apollo 11 lunar laser ranging retro-reflector array, which is still being use to this day.
Why are there no stars in the photos, well come we are photographers and we know about dynamic range. Just go out at night in a brightly lit city and take a photo, there will be no stars in your shot too and that's with 40 years on improved camera technology.
As for seeing what they left behind with a telescope that's just not possible at the moment. The Hubble is probably the best telescope we have, but if we point it at the moon each pixel from the Hubble would be about 10 meters across on the moon, far far to big to pick up a any thing left by the Apollo missions.
It's not as if only the American went to the moon, they are just the only one to send a man there, the Russians where the first to orbit the moon and the first to take photos of the dark side.
If they did not go then the Americans lied, the Australians lied (Parkes Radio Telescope) the UK lied (Jodrell Bank) and yet not one single person has owned up to the lie.
Why build the space station then? It's 220 miles up into space. The moon is approximately 250,000 miles away.That's like me planning to make a trip to London and deciding instead to build a stopping off point at the end of my garden path....
The Station HAS to be at a distance that will keep it in earth orbit, also remember this is the
International space station, you have to put it where other countries want it too.
Why have we not been back? It's not about technology but money. They need to have the public behind a mission if they are going to spend millions of tax dollars. There just has not been that public appetite.
