Astronaut Scott Kelly is back on Earth..

[Hog]

..after a year aboard the ISS.

His face sure thinned out quickly after being affected by gravity again.  There is a large fluid shift in the human body in microgravity.

I recently got a chance to hear a presentation by one of Astronaut Kelly's doctors. They've extrapolated data which shows that the average human would lose up to 50% of their bone density if in orbit over 30 months. Some of that mineral material would be excreted through urine.

Why the concern over long term exposure? Because NASA and the private space agencies are looking toward Mars. It's estimated that a trip to Mars (from the moon, not even Earth) would take 3 years. That's 36 months. How does the body hold up? Not to mention that on the Moon, you weigh about 16% of your Earth weight. On Mars, that weight goes up by a bit more than double.

The human body, it seems, adapts itself to foreign environments in a way. The inevitable conclusion, with today's science at least, is that our first Mars astronauts may never be able to come home- because being back on their mother planet could kill them.

There are ways to circumvent low and zero gravity. Not saying they are cheap but available technology can easily make a space craft that rotates at a speed to mimic Earth's gravity. Once on a planet with lower gravity, suits with extra weight could be worn to simulate the effect of Earth's gravity.

Robert Zubrin pointed out that artificial gravity actually is cheap, all you need is a counterweight and a cable that allows the crew capsule to rotate around a fixed point on the cable.

Apparently he is now 2 inches taller than his twin brother but will shrink back. The article does not mention what brand of beer Biden delivered to him. Curious minds want to know.

What's always interested me is the method the Russians use for bringing cosmonauts/astronauts back to Earth.  Instead of landing their Soyuz capsule in the water, they come down on land.  In addition to a huge parachute, they also fire a cluster of retro rockets just milliseconds before impact to lessen impact loads.  Even assuming those rockets work as designed, the landing impact loading on the bodies of the crew is still about that of a 40 mph car crash.  Yes, they are seated in impact attenuating seating, but it's still a wallop.  Considering the loss of bone density and muscle atropy rssulting from a lengthy period in a zero gravity environment, I'm amazed the crew does not sustain more serious injuries than that we hear.

This is true. I think one of the main concerns is doing this cheaply not only from a monetary standpoint, but from an energy consumption standpoint.

Oooof. I've heard that they actually "softened" the landing systems over time. The current 5 G's used to be 12 G's. However, there have been reports of some modern landings coming in steep and hitting 9 G's. No thanks!

This is the truly important question! I think it's some of the Presidential brew.

Spaceflight osteopenia (bone loss during spaceflight) is less than 1%/month on ISS.  Normal bone loss for the aged is 1.5-2% per year and 2-3% per year is normal for post menopausal men.

New drugs are shown to almost stop this process of spaceflight osteopenia. Combined with exercise bone and muscle wasting can be virtually arrested.

Space medicine is very important because even now the accurate study sample size is very small.  Much early Mir and older science is inaccurate.

The extra height comes from the decompression on the spinal vertebrae causing the disc to swell. The height is lost quickly when gravity is restored.


A lot of the highest G loads are felt when the capsules are decelerating from orbital velocity as the vehicle is re entering the atmosphere.  Esp. during off nominal entry profiles.  We are talkking about decelerating from 17,500 mph to a terminal velocity speed.  The parachute speed to the retro rocket firing is jolting, but the sustained G loads are much less.

2 football players tackling each other reach accelerations of 70 g's, but only for a few milliseconds.

Actually Hog is correct. After a quick google it seems there are some writings on the subject.

Still suspect medically from the quick search I did. But lucky for us we got HGH from old Art show ads and "Low T" and "ED" drug commercials during sporting events to fix us. Geez.

[Hog]

Sory folks, I meant post menopausal WOmen. Men dont menstruate, so we cant be meno-pausal, but andropause does occur as men age as out endogenous testosterone levels decrease.  This is where the term "grump old men comes from" as with hypogonadism(low t levels) comes irritability. 
(We all have that older Uncle that falls asleep in his chair after Thanksgiving/Christmas dinner. Also a sign of hypogonadism or Diabetes Mellitus).

A decade or so ago I had a older (to me at time) coworker who, for some reason, had doc put him on some testosterone treatment. I recall a gel? Not sure.  He really changed. Hitting on all the secretaries, wanting to go out partying and hit all the happy hours with us, started his guitar again and really was wanting to "get the band back together." It was funny to see.

There is a cream, there are injections, and pills. To each there own. New data is suggesting anyone with any cardiac issues should avoid testosterone treatments. LowT is a great marketing scheme. And yes there are some physiological effects from low testosterone. But in the overall I am not sure most of the symptoms are not also related to age, level of activity and yes mental health. Is that a catch 22 scenario? certainly could be. But in particular the testosterone gel is specifically named (androgel) for increased risk of heart attack. Then all other testosterone replacement therapy are spotlighted for a broader range of cardiovascular problems.

Yeah. I never bought into Art's or worse now Norrys stuff or the commercials incessant about LowT, ED. I always laughed, a bit, at two things specifically: the "blindness" that could be caused by one (so going blind helps one getting 'up'? Maybe new wife or think of someone else? And 'lasting more than 4 hours and seeking help.' A Skinamax porn scenario...candystriper nurses at hospital trying to take care of this problem.) Before u complain I know these conditons are real and could be serious. Also not against medicine, vaccines, doctors, psychiatry,  .but first 'do no harm' and second opinins, heathy living, ect.

I wonder if any other parts of the body grew during his time in space?

It's never been tested in space on a major scale, but some experiments have been done such as with Gemini 11 where they did produce a small amount of artificial gravity by spinning the spacecraft. It's just basic centrifugal force, so there's no reason it wouldn't work in space on a major scale. Zubrin lays out the design in his book "The Case for Mars". On a planet, however, that method wouldn't work at all but on a place like Mars where there is still some gravity there aren't the same issues at play as with being completely weightless.

They also inadvertently generated "some gravity" with Gemini 8.  Armstrong sure seemed to have lady luck on his side, throughout his career, after his numerous narrow escapes, even before Apollo 11.  His skills as a pilot no doubt helped out, as well.

Indeed, Neil Armstrong was the luckiest guy on earth (and the moon) not to have died in any of the mishaps that occurred over his career. Classy guy to boot, I always had a lot of respect for Neil.

Armstrong also ejected from his battle damaged USN Panther jet during the Korean War.

Yep.  The wiki write-up for Edwards alone is worth a read just for all the incidents he survived.  One hell of a pilot, one hell of a man.  We could use more Neil Armstrongs.

'Allo!
With you yet am i.
Noteing the false synchronicity of Congress-fakette-'victim'Grabby Giffords,annexing itself from AZ psyop=Gladio_USSRA linked to this twinned astro-not.
It's self-evident that the two recovered via soviet re-entry vehicle were in an party datcha black sea resort for an near-year,shooting special-effects daily in the sovietised fake hot-springs pools wearing indoor jump-suits so possibly in mineral oil tank with lo-voltage technology in sets that resemble hypothetical space-vacuum interiors.
Alternateley,ussra astro nots use disposeable clones that are photographed in an oxygenated ultra-dense fluid,ie,silicone,and suited up,ejected from an airplane aboard an fake re-entry mock-up like structure,films of bail-outs,de-compression,parachuteing out,doa 'recovery',all by usual ussra tech film studios in soviet film complexes.
Giffords link proves entire station story is false flagged agit-prop,no truth any part.
Looks,smells like Orwell wrote the script,Kubrick's clones filmed it in both star kkulty komplexes...

I love hearing about all the stuff those guys did. Legit badassery. A former astronaut candidate I once spoke to called them "cowboys of the air."
