Is the Van Allen belt fatal?
« on: 19/02/2009 12:30:01 »
Emmanuel Mamo asked the Naked Scientists:
   
Can really man live through the Van Allen belt?  And then through the solar flares?  Is it true that man never landed on the moon, because of these dangers?  If they did land on the moon, why there are no reports of space vehicles seen from Earth?

What do you think?

They did land on the moon and laser reflectors left behind on the moon can be detected from the earth. Scientists knew about the Van Allen Belt and took special precautions to avoid its effects.
Results of experiments using these are reported regularly.

The ongoing Lunar Laser Ranging Experiment measures the distance between the Earth and the Moon using laser ranging. Lasers on Earth are aimed at retroreflectors previously planted on the Moon and the time delay for the reflected light to return is determined. Since the speed of light is known with very high accuracy, the distance to the moon can be calculated. This distance has been measured with increasing accuracy for more than 35 years.

Hi Emmanuel
Yes the belts are there. No the levels of radiation are not high enough for a brief journey through the belt.
This guy as some thoughts on the matter:

The radiation is just one of the ideas which the conspiracy theorists come up with but it's not a real issue. If someone told you that you may have a few percent extra chance of cancer before you're 60, would that seriously put you off volunteering for a mission like that? (Compared with the possibility of blowing up on the launch pad, that is.)

It would be interesting to study the age range of the conspiracy theorists. I wouldn't mind betting that the vast majority are too young to have actually seen the events on TV when they happened.
