The Apollo Missions and Van Allen Radiation Belts

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.

There are two Van Allen belts:

  • The inner belt. Smaller and has stronger radiation.
  • The outer belt. Larger and has weaker radiation.

During an intense solar activity, sometimes a temporary third belt may appear.

The Apollo missions simply bypassed the more dangerous inner belt. They didn’t go anywhere near it. Apollo went through the outer belt that has weaker radiation. And even then, they rushed through the weakest part of it, in not more than a few minutes.

Each of the astronauts wore a personal dosimeter in order to record the amount of radiation they received. The result? Each astronaut received the same amount of radiation as a single CT-scan, during the entire mission.

The Thermosphere Layer

Flat-Earthers often get confused and think the thermosphere layer is the same as the Van Allen Radiation Belt. The reason is that both are used as ‘evidence’ of the impossibility of space travel in their misguided community.

They are not the same thing. Read more here about the thermosphere layer.
