Physics/regarding moon landing

Question
Hi,

Many claim that human moon landing is a hoax. The photographs released shows shadows in multiple directions, flags waving as if there is wind. Also USSR was having competent space program like USA, but surprisingly even after 50 years, no other country could do human landing on moon. How is it possible?

Regards

Answer
Flags swing, all the optics were explained (and used in scientific discoveries, no less).  The USSR had a competent space program for getting spacecrafts up, but not for safety or for keeping them up.  Other countries (recently, China) have been to the Moon, but not back.  We can do this, it's just that the wind seemed to go out of the sails of that mission when we finally landed there...and kept going.  We went.  We came back.  We need to go again, it would be SO amazing to have new Moon rocks again!

Expertise

I can answer most basic physics questions, physics questions about science fiction and everyday observations of physics, etc. I'm also usually good for science fair advice (I'm the regional science fair director). I do not answer homework problems. I will occasionally point out where a homework solution went wrong, though. I'm usually good at explaining odd observations that seem counterintuitive, energy science, nuclear physics, nuclear astrophysics, and alternative theories of physics are my specialties.

Experience

I was a physics professor at the University of Texas of the Permian Basin, research in nuclear technology and nuclear astrophysics. My travelling science show saw over 20,000 students of all ages. I taught physics, nuclear chemistry, radiation safety, vacuum technology, and answer tons of questions as I tour schools encouraging students to consider careers in science. I moved on to a non-academic job with more research just recently.

Education/Credentials
Ph. D. from Duke University in physics, research in nuclear astrophysics reactions, gamma-ray astronomy technology, and advanced nuclear reactors.
