On December 3, 2014, NASA published a video describing the Orion EFT-1 mission, narrated by a NASA scientist, Kelly Smith. The mission was the first unmanned flight of the Orion spacecraft.
Some unscrupulous flat-Earthers decided to turn the video into ‘evidence’ that NASA never went to the moon. They cut down the video to the ‘important’ parts and added in prejudicial narration and subtitles. There are countless of such videos on YouTube, and at some point, it was nearly impossible to search for anything educational about the Van Allen radiation belts on YouTube.
They are wrong. There are, in fact, two Van Allen radiation belts. Apollo traversed the outer belt that has lower radiation level in a hurry, while Orion was deliberately sent into the far more dangerous inner belt. They are named ‘belts’ precisely because they are like the real belts. It is possible to bypass the most dangerous parts of the belt, just like Apollo did.
Orion EFT-1 is not ‘evidence’ that the Apollo mission didn’t happen.

A widespread misunderstanding within the flat-Earth victims is related to velocity/speed. They seem to think velocity is absolute, while in reality it is measured from a specific frame of reference. Example:
“If the Earth is in motion around the Sun at 30 km/s, and Apollo traveled at only 11 km/s, then how could Apollo astronauts possibly make it back to the Earth?”
We used to measure velocity/speed relative to the surface of the Earth. But it is not always like that.

The film ‘Dark Side of the Moon’ is a mockumentary. It is fictional but presented as if it is a real documentary. The film features guests like Donald Rumsfield, Henry Kissinger, Alexander Haig, Vernon Walters, Buzz Aldrin, and Stanley Kubrick’s wife. In the film, they all pretend that the Moon landings were faked, and created in a studio by Stanley Kubrick.
There are many doctored versions of the film circulated on the Internet. Usually, the ‘giveaways’ are cut to make the film more believable. Then, the film is presented as ‘evidence’ that the Moon landings did not happen. Unfortunately, many believe these edited versions of the film and don’t realize the events in the movie are entirely fictional.

Van Allen Radiation Belt is a zone of radiation encircling the Earth. To flat-Earthers, Van Allen Radiation Belt is ‘evidence’ of the impossibility of space travel. To the rest of us, the Van Allen Radiation Belt is one of the challenges which is not impossible to overcome.

The thermosphere is a layer of the Earth’s atmosphere from about 95 km to 600 km. It is named ‘thermosphere’ because its temperature increases with altitude. The temperature in the thermosphere can reach 2500°C. However, air density in the thermosphere is very low to the point that heat conduction practically does not occur. Objects in the thermosphere will feel cold.
Flat-Earthers discovered that the temperature in the thermosphere could reach 2500°C. They are happy to ignore the other information which usually accompanies it: the air density up there is also far lower.
