Satellite Watching

It is not hard to spot satellites. Satellites can easily be seen under the following conditions:

  1. They are easier to see the larger and the closer they are.
  2. The darker the sky, the easier to see them.
  3. 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.

Galilean Moons: The First Objects Observed to Orbit Another Object

Jupiter possesses four large moons: Io, Europa, Ganymede, and Callisto. These are called the Galilean Moons. They are easy to observe and the first objects found to orbit a planet other than the Earth.

Flat-Earthers are often seen demanding proof that an object can orbit another object. All they have to do is to use a telescope to observe Jupiter and its Galilean moons.

Geostationary Satellites

A satellite can be placed in an orbit 35786 km above Earth’s surface, and the satellite will be in motion at the same speed as the rotation of the Earth. As a result, the satellite will appear practically motionless when observed from the surface.  Many communication satellites are placed in this orbit, and a satellite dish receiving signals from the satellite doesn’t have to track the satellite.

Flat-Earthers often take the fact that satellites are in motion and most satellite dishes have a fixed direction as ‘proof’ there’s something suspicious about satellites. They are wrong.

Iridium Flare

Iridium is a satellite constellation consisting of 66 satellites. It provides satellite phone services over the entire Earth surface. The first generation satellites have three door-sized reflective antennas. Because of their reflectivity, Iridium satellites will occasionally reflect sunlight to Earth’s surface. The Iridium flare will look like a bright flash over a few seconds.

Most flat-Earthers deny the existence of satellites. Iridium flares provide an easy opportunity to confirm the existence of satellites, at least until the end of 2018, when they are replaced by newer non-reflecting satellites.

Celullar Network vs. Satellite Communications

“If satellites really exist, then why would mobile phone operators bother to install transceivers everywhere?” Flat-Earthers ask this question a lot.

Their logic is that if using a satellite can get you a huge coverage area, then spending a lot of money and effort to install towers everywhere does not make any sense. Usually, they would follow-up and conclude that “satellites don’t exist”.

They are wrong. Satellites do exist, and there are good reasons why mobile phone communication utilizes cellular architecture.

The MH370 Disaster and the Inability of the GPS System to Locate It

The GPS system is one-way. The satellites broadcast signals. GPS devices receive and process the signals to determine their location.

Flat-Earthers often point out the fact we were unable to locate the ill-fated MH370 as ‘evidence’ GPS doesn’t work and therefore doesn’t exist. They are wrong. GPS satellites never receive any signal from GPS devices, and it is not possible for them to locate MH370.

The Size of North America in Pictures of the Earth Taken From Space

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.

Why Don’t We See Satellites in Photos Taken From The ISS?

“Why don’t we see satellites in photos taken from the ISS?” (or from space in general). That’s a recurring question within the flat-Earth community, usually asked without expecting an answer, assuming that an answer is impossible, and that it is a glaring oversight when the powers that be purposefully made the picture using CGI.

But no, the pictures are real. And satellites are not visible because they are too far spaced apart from each other.

Curved Rocket Trajectory

Every time we see a rocket launch, its trajectory is always curved, never straight up. Why would they do that? Aren’t they supposed to go up to space?

No, it is not because they have malicious intentions, as implied by a lot of flat-Earthers.

The curved trajectory is what we call the ‘gravity turn’.
