I find it interesting that NASA has planned a return to the Moon to coincide with the next cycle of the sun when it will be at it's minimum of
You wouldn't want the astronauts to be on the surface of the Moon or in transit during a violent eruption from the sun, they could take a lethal dose
of radiation, or enough to cause them health problems in the future.
I think if man is going to build a permanent base on the Moon we will have to live underground for protection from radiation and imacts, and people
will have to limit the amount of time each person spends on the surface.
Shielding is going to be a concern to Lunar colonists. Not only from radiation, but without an atmosphere to protect you, you need to think about
impacts from space rocks and the ejecta they throw out.
A small rock coming at the Earth will burn up or explode in the atmosphere, on the moon it would come in at full speed and any ejecta would have far
reaching consequences due to the debris that gets blasted off the surface, only to fall back and cause secondary impacts.
Solar weather is going to be a huge concern for our future space missions, especially when mankind first starts out with manned exploration to other
And places like the ISS and future orbiting space stations such as hotels and research platforms will need to have radiation "Safe Rooms" so that
people can retreat to a secure place during a blast from the sun.
I read somewhere that a water tank the size of the Destiny Module
with a habitable cylinder down
the center would offer some pretty good protection for astronauts as an emergency shelter from a large solar event. Sorry I don't have a link to back
that up, but water is supposed to be able to stop a lot of the harmful radiation.
No matter what the Sun does though, I think we'll all still be here after this next solar max.
And who knows, we may learn something about hardening our future spacecraft and infrastructure against this sort of thing so that it's not a problem
down the road...........
