NASA engineer admits they can't get past the Van Allen Belts (Just for you Gary Gorrell) (https://www.youtube.com/watch?v=NlXG0REiVzE)

If what the guy said is true then nobody left earth.
Especially with that radiation field.

A disputed topic of all times . Can anyone explain how the flag was moving without any atmosphere on the moon ?

Yes. I don't believe that we were on the Moon. It is fabricated hoax. Nothing more. Just like 9/11 was an inside job and not Al Qaeda doing. Nothing new here.

How people claim it was a hoax:

How people claim it was NOT a hoax:

No atmosphere=no friction. An object in motion stays in motion until an outside force counters it. The main two being friction (none present), and gravity (less gravity on the moon). If you were to pick up a rock and throw it in space with no gravity present, it would continue moving at that same speed almost indefinitely. So yeah, it's absolutely plausible that the flag would continue moving for quite some time with only a little bit of gravity to act on it.

Thank you that I didn't have to write it down myself.

@Radiation
The whole video was about the design and testing of the orion spacecraft. It has to be tested and the radiation has to be measured in order to know with certainty that it will not harm the crew. The video doesn't say anywhere that there is no way to shield the spacecraft or that the Apollo mission spacecrafts were not shielded.

According to this (https://www.hq.nasa.gov/alsj/tnD7080RadProtect.pdf) source, Apollo 11's crew had an average radiation dose of 0.18 rads (https://en.wikipedia.org/wiki/Rad_%28unit%29).
Another source (http://www.popsci.com/blog-network/vintage-space/apollo-rocketed-through-van-allen-belts) says that "Over the course of the lunar missions, astronauts were exposed to doses lower than the yearly 5 rem average experienced by workers with the Atomic Energy Commission who regularly deal with radioactive materials." (simply to put the 0.18 rads in perspective)

Also, the video doesn't say that we cannot get past the Van Allen belt  ;)
It simply says that "we must solve these challenges ...", which refers to this particular spacecraft and means that we have to prove that (this particular spacecraft) is capable of safely passing through.

@Use the same radiation shield as in Apollo missions
This is not a toaster that you can take off the shelf and use it. It is designed, manufactured -and probably improved- specifically for that one spacecraft.

Radiation is strongest (many many miles) above the equator and weaker around the arctic circle. The Apollo moon missions flew through the weaker parts of Van Allen Belts. The astronauts were exposed to radiation but not enough to kill them or give permanent damage.

The Orion spacecraft is designed for longer journeys in space (to asteroids and Mars). This requires much better radiation shielding and scientists are working on it.
