Probably due to right wing politics and individual freedom. Must be man made./SAR What do these dumbsh**s expect to do about something like that if it really is happening? I guess this is the new scare to replace global warming now that it is dead. Has anyone noticed you hardly hear anything about “climate change” now, it seems to have died a quiet death over the last several weeks and now we have deadly radiation to worry about.
The reason mars has such a thin atmosphere is because it last its liquid core long ago, which in turn caused a loss of the magnetic field, which in turn allowed the solar winds to gradually tear the atmosphere from Mars and will eventually eat all of it.
This is one of the major problems facing scientists who want to terraform mars, without the magnetic field any atmosphere they might happen to develop on Mars would just dissipate into space.
Now please don't ask me a lot of technical questions,what I have just posted is true, I read a lot and I obtained this information from some scientist whose name I can't remember but google should bring you the info on it if you want to go to the trouble to look it up.
The Nasa pukes know all this, as a matter of fact I seem to remember Nasa talking about Mars lack of a liquid core only last year. Do you think maybe they have an agenda with all these scare stories?
