It is not hard to spot satellites. Satellites can easily be seen under the following conditions:
- They are easier to see the larger and the closer they are.
- The darker the sky, the easier to see them.
- Satellites are visible only when they are lit by the sunlight.
Because of these conditions, satellites are usually seen a few hours after sunset or a few hours before sunrise.
Flat-Earthers claim that satellites can never be seen, and the fact is evidence that “satellites don’t exist”. They are wrong. Satellites can easily be seen under the right conditions.

The Apollo missions were real and humans have actually visited the Moon. If someone fell victim to the flat-Earth conspiracy, then it would imply that they also fell victim to the Apollo moon landing conspiracy. They are wrong.
Someone usually fell for the moon landing conspiracy theory because of provocation and confirmation bias, and also because of their ignorance of the Apollo mission profile itself.
The following is a very brief description of the Apollo mission profile, numbered according to the numbers in the illustration.

These days, predicting eclipses is easily done using computers. Prediction is made by determining the position of the Sun and the Moon at a time, and calculating if an eclipse happens. The same procedure is then repeated numerous time, each for a different time.
The victims of the flat-Earth dogma insist nobody can predict eclipses from the position of the Sun and the Moon. They believe NASA simply used the Saros cycle to predict eclipses by calculating the interval between eclipses. They are wrong.

In many pictures taken from space, stars are not visible, even with a dark sky. The reason is that stars are very dim compared to the primary object in the pictures. If the camera is set to take a correctly exposed image of an object that is much brighter than the stars, then the stars would not be visible in the picture. The same thing would happen everywhere, in space, or on the surface of the Earth.
Flat-Earthers often take the lack of stars as fakery. They are wrong. This is simply a limitation of any camera.

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.

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 are faked, and created in a studio by Stanley Kubrick.
There are many cut 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 Moon landings did not happen. Unfortunately, many believe these unfaithful versions of the film and don’t realize the events in the film are completely fictional.

How much of Earth we can see at once depends on our distance from the Earth. The closer we are to the surface of the Earth, then the smaller part of the Earth we can see at once. Conversely, the farther we are from the Earth, more of the Earth are visible to us.
The difference in the size of North America in these pictures relative to the size of the Earth is often presented as “evidence” that we have been lied to. In reality, it is simply a perspective effect. The pictures are taken from a different distance from the Earth and with a different camera field of view.

A page on NASA’s website is at the center of the attention of flat-Earth followers. It is a page created by Fred ‘Mr. Eclipse’ Espenak, explaining the Saros cycle. Here’s the first paragraph from the page:
The periodicity and recurrence of eclipses is governed by the Saros cycle, a period of approximately 6,585.3 days (18 years 11 days 8 hours). It was known to the Chaldeans as a period when lunar eclipses seem to repeat themselves, but the cycle is applicable to solar eclipses as well.
After they discovered that the said ‘Chaldeans’ was a civilization from 25 centuries ago, they got excited and jumped to the conclusion that NASA used ancient technology to predict eclipses, and thus eclipses can’t be predicted from the motion of the Sun, Earth and Moon themselves.
Like other similar cases, this tells us more about the flat-Earthers themselves than about NASA.

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 that is not impossible to overcome.

Every time NASA (or anyone else) releases a picture of the Earth from space, flat-earthers would compare it to another picture of the Earth. Obviously, every photo is going to be different from another, but flat-earthers love to use this fact as a ‘proof’ that these photos are results of image manipulation, and that we are being deceived somehow.
