Title: Can we live with Mercury-Mars gravity forever?
Post by: Zichichi on 02/02/2006 17:33:19

I would want to know if is possible to live
with Mars-Mercury gravity as on Earth......


Thank you..... [:)]


nothing is created and nothing is destroyed

""  MARS MICE by Karen Miller
 
In 2006 a group of mice-astronauts will orbit Earth inside a spinning spacecraft.
Their mission: to learn what its like to live on Mars.

The mice will be exposed to Mars-gravity for about five weeks. Then, says Wooster, they'll return to Earth alive and well. The mice will descend by parachute and land near Woomera, Australia, inside a small capsule reminiscent of NASA's old Apollo capsules.""

I look forward to the mices press conference !  [:D]

Men are the same as women.... just inside out !!

Low gravity leads to a change in bones. Bones need pressure to grow or the reverse, it would either make us taller or shorter.

Your heart would weaken from ease as with other muscles.

So... What happened with the mice?

Seems it didn't go that well. Neither did the others. http://www.astronautix.com/b/biosatellite.html

Like many other proposed missions, it never got past the planning stages before its funding was cut. The mission never took place.  The time span for planning, designing, building, and launching missions can be long, and priorities can shift in that time.  In the form the late 50's to early 70's, we did a lot of work on developing a nuclear rocket design that could have taken us to Mars,  By 1968, we had developed an engine that could have worked for a Mars mission, and by 1972 we were ready to start integrating them into spacecraft.  Then Congress "pulled the plug" on the space program. Pretty much all funding was dropped except for the Space Shuttle program. ( Apparently the" powers that be" of the time thought a "space truck" was more important than exploration.)

A pity Janus. It seems to me a noble goal, and a real adventure for us all. Reading you I started to search anew and found this https://en.wikipedia.org/wiki/Mars_Gravity_Biosatellite . But it also seems like we've tested it further with the space shuttle  " Spaceflight on the Bion-M1 biosatellite alters cerebral artery vasomotor and mechanical properties in mice " https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4385880/  Hmm, okay, both the space shuttle and this Russian experiment.

And that makes me wonder if we won't need some kind of artificial gravity to counteract it, for longer journeys.
