Buff space mice could stop astronauts from losing bone and muscle mass

I am seriously disappointed you didn't have an artist make a render of "Buff Space Mice" with six pack abs... :)

No matter how you throw the dice, it all ways comes up snake eyes. In order for humans to exist in space we need all the things humans need to survive. Air, food, water protection against radiation, and gravity. In order to inhabit a ship large enough to produce gravity, we need really large spaceships, This mega ships can only be manufactured in the environment of space. That means we need to build shipyards to do R&D and build these future transport systems. We have shipyards on Earth; we need shipyards in space. Can we build the Arnold Schwarzenegger that would be super buffed to be future astronauts? Wow! A whole army of human terminators. It would like He-Man and the Masters of the Universe. It would be better than Roger Ramjet. I feel I am about to faint.

Comment Author Dr. Ravi Sharma also submitted a proposal as Principal Investigator with overall title: “Microgravity, Developmental Biology & Genetics” and specific subject: “Mammal Survivability, Genetic Adaptation & Species Evolution In Microgravity Long Duration Missions”, in response to NASA Gravitational Biology and Biomedical Research and Countermeasures Programs Research Announcement NRA-96-HEDS-04 Dated Dec 27, 1996, on 31 March 1997 from Hughes STX Corporation (97-OMG-150). https://taskbook.nasaprs.com/peer_review/nra/old/96_HEDS_04.html. The proposal was to study 60 successive generations of Rodents over 10 years period on Space Station, with in-depth comparative bioinformatics on genetic and physiological performance in, adaptation to microgravity, with several generations returned to Earth for comparison with samples of 60 Generations on Earth. An elaborate databased information system would keep track of any indicators of mutation, genetic changes, reproduction and repair aspects. NASA found proposal useful but elaborate Lab required was not funded. Subsequently various elements of similar studies have been carried out on ISS which are referenced throughout. Author has been also active in microgravity effects on Human life. <<Personal information removed by moderator. Never post your email address.>>

I would like to know what happens to the human physiology when there is no microgravity present, and the body is between planets, like being between the Earth and Mars? Do we have simulations of what would happen? How far does microgravity extend till there is no gravity? How many will have to die for us to find out?

The extent or strength of microgravity felt in space depends on the other gravity carrying matter around the spacecraft and also if there are relative movements of matter and people. the points in orbit where e.g. gravity between earth and mars equals are like lagrangian points where if other factors are neglected and no thrusters are fired, the space craft can stay there for long periods, reality has other perturbations and microgravity effects.

For long duration missions spinning stations have been proposed to create artificial gravity so the physiology mimics earth experience and people are likely to stay healthy.

Solar study satellites form NASA and ISRO use the Lagrangian points to keep looking at the SUN.

As in above post I also proposed 22 years ago for the ISS an expoeriment to measure microgravity effect of particles and their random movements in a balloon fixed with micro imaging systems to record these movements. After 20 years of that proposal hundreds of experiments on ISS have provided that type of data as well as effect of microgravity in varous phases of matter Solid, Liquid, vapor/gas and mixed phases as well

Kristianna to answer your question.

Further weightlessness or microgravity results in bone loss, effects on vision, blood bulging the vascular system near heart areas and not reaching limbs etc.
As far back as Skylab, the first NASA Space Station, for 64 days duration, we designed a lower body negative pressure equipment that pumped blood to extremities thus keping eathlike effect.

Nowadays in first class seats and hospitalbeds the pumps working on legs etc simulate the same thus keep the circulation.

I am in process of publishing an article on spaceflight health and medicines.
