Well that's a complication:

Hmm. That's troubling. Generally with radiation we think about energetic damage to DNA and often cancer. The vascular issues are a little hard to connect. When I first read your article title I thought maybe the low gravity would alter the dynamics of perfusion and arterial pressure and venal blood flow.

That's the same direction I thought they were going, but it rather surprised me.

I guess the continual radiation bath is much worse than we'd thought.

There are other places elsewhere talking about the mitigating factors, from the sample size to the ages of the astronauts examined, etc.

The "science" is not sound.

We are going to Mars.

You mean UV radiation really does cause melanoma?
You mean global warming is actually real?
Oh crap!

The sample size issue is clearly the most contentious aspect, as there were only 24 Apollo astronauts to begin with, and 8 have died. I'd think that it's a bit premature to ascribe a definitive root cause to these deaths, but it is worth noting and studying. In general, cosmic radiation was already recognized as perhaps the most serious threat to deep space travel and NASA is spending a significant amount of time researching how to protect our future Mars explorers from it.

As they should, of course. Because whether this particular thing is true or not, it is still a hazard.

I suspect regular exercise will help mitigate the effects of zero-G, and of course generous radiation shielding (such as enormous tanks of water around the living area) should help with that radiation.

We're going; we just have to work out the details now.

Both you and Tray are going ?
This Mars mission may be worth a bob or two of government money

So going into deep space might expose you to more radiation (duh) and possibly shorten your life by a few years?

Man, who cares? I'd go in a heartbeat*!

Absolutely..

Jerry Doyle recently died at the age of 60.
Andreas Katsulas (Age 59)
Richard Biggs (Age 44)
Michael O'Hare (Age 60)
Jeff Conaway (Age 61)
Tim Choate (Age 50)

All shared the same deep space mission.

For Frigg's sake, tstone, the study validated the claim whether radiation would damage the cardiovascular system with an animal model. They were not just relying on the necessarily small sample set of Apollo astronauts.
