DNA of Astronaut No Longer Matches His Twin After He Spends a Year in Space

[BenInHer]

they guy looks more healthier then his twin in the still picture, no?

Interesting. Is he the astronaut husband of the congresswoman who was shot?

dunno, it just been poppin up on my youtube for awhile now. cool video nonetheless

Sensationalist garbage.Most of the effects can be linked to the rigorous exercise taken by the astronaut. All other effects reduce overtime, I think they need to conduct studies over years to see if those minimal effects are temporary etc.

Ex-congresswoman Gabrielle Gifford from Arizona (one that was shot) is the wife of retired astronaut Mark Kelly.

I sure as hell do not wanna spend two years in a capsule to get to Mars. These capsules are made for people small in stature. I fret sitting for 20hrs (one way) for my flights to and from back home. Two years in a capsule? Heck no.

You think rigorous exercise will change your DNA?

If i ever get hit with child support I'ma take a 6 month trip to space hopefully my DNA changes and I can come back and claim the kids not mine

Yes, well it changes EPI Genetics which is the major change in the space faring twin

Cosmic radiation dude!!
The poor man was baked by radiation,
Fucked up is DNA and rna strands.
He is lucky he doesn't have cancer.

They try to reduce the amount of metal in space crafts but it's not enough, secondary radiation from the metal surrounding you is worse than direct exposure to cosmic radiation.

Material science has come a long way ,
They should be able to build fully composite structures from carbon fibre, aramids, plastics etc.

Or even better magnetic envelope protection for spacecraft, at least 10 Tesla.
But then again the power requirements are greater than supplied by solar panels,
So nuclear only option.
