Is there any truth to the rumor? Is it impossible to travel to the moon, because of the Van Allen Belt?
This is an especially interesting question, though maybe more about psychology and epistemology than about astronomy or physics. Nevertheless, the same question comes up again and again, in one form or another, so it really is very important.
The Apollo spacecraft passed through the Van Allen belt quite quickly, so that in the short time they were exposed, the astronauts did not receive a dose of radiation considered dangerous, at least not compared to the inevitable other risks in the mission.
