are bodies preserved in space?

If you do die in space, your body will not decompose in the normal way, since there is no oxygen. If you were near a source of heat, your body would mummify; if you were not, it would freeze. If your body was sealed in a space suit, it would decompose, but only for as long as the oxygen lasted.

How long can the body remain preserved? A body presents little threat to public health in the first day following the death. However, after 24 hours the body will need some level of embalming. A mortuary will be able to preserve the body for approximately a week.

Depending on where you are in space, this will take 12-26 hours, but if you're close to a star, you'll be burnt to a crisp instead. Either way, your body will remain that way for a long time. Gut bacteria will start to eat you from the inside out, but not for long, so you will decompose very slowly.

Once submerged, the body stays underwater until the bacteria in the gut and chest cavity produce enough gas—methane, hydrogen sulfide, and carbon dioxide—to float it to the surface like a balloon. (The buildup of methane, hydrogen sulfide, and other gases can take days or weeks, depending on a number of factors.)

The first space burial occurred in 1992 when the NASA Space Shuttle Columbia (mission STS-52) carried a sample of Gene Roddenberry's cremated remains into space and returned them to Earth. The first private space burial, Celestis' Earthview 01: The Founders Flight, was launched on April 21, 1997.

Containing about twenty bodies in total, each exhibition uses real human bodies that have been preserved permanently by a process called "polymer preservation" (commonly referred to as "plastination") so that they will not decay.

Yes, anaerobic (doesn't need air) and aerobic (needs air) bacteria assist in decomposition. If encased in cement the body will likely decompose slower as much if the aerobic bacteria will be rendered useless and the body will be protected from the environment but the cement will not preserve it indefinitely.

Embalming is the practice of preserving human (or animal) remains. However although embalming slows decomposition it does not stop it indefinitely. ... If placed in a dry enviroment or special fluid some embalmed bodies may end up mummified and it is not uncommon for these bodies to remain well-preserved.

As a general rule, yes. A cadaver in the water starts to sink as soon as the air in its lungs is replaced with water. Once submerged, the body stays underwater until the bacteria in the gut and chest cavity produce enough gas—methane, hydrogen sulfide, and carbon dioxide—to float it to the surface like a balloon.

Space is the vacuum that exists between celestial bodies. The simplest explanation is that it's just an empty area . Atmosphere on the other hand is the sum of gases that suround a celestial body. Our atmosphere for example is composed of nitrogen oxygen argon and carbon dioxide.

Space is a vacuum — so it generally doesn't carry sound waves like air does here on Earth (though some sounds do exist in outer space, we just can't hear them). But the various probes zooming through our cosmos are capable of capturing radio emissions from space objects.

That increased radiation can affect their cells and increase their risks for a variety of cancers. That is aging. An astronaut, by being in microgravity, experiences bone loss. While in space, astronauts lose up to 1.5% of their bone mass for each month spent in space.

Comets are icy bodies in space that release gas or dust. They are often compared to dirty snowballs, though recent research has led some scientists to call them snowy dirtballs. Comets contain dust, ice, carbon dioxide, ammonia, methane and more.

Though space is typically very cold -- most floating objects have a surface temperature of -454.8 degrees Fahrenheit -- a person would not instantly freeze because heat does not transfer away from the body very quickly. On earth, heat can be transferred via convection, but outer space is mostly nothingness.

Space junk can be a hazard to active satellites and spacecraft. It has been theorized that Earth orbit could even become impassable if the risk of collision grows too high.

A number of the bodies are remarkably well-preserved: Sun-bleached parkas outline faces frozen into the color of charcoal. Gelje Sherpa, a guide and six-time summiteer, said that when he first climbed Everest in 2008, he found three bodies. During a recent season, he saw at least twice that number.

After about one minute, circulation would stop altogether. After another minute, you'd be dead by asphyxiation. There is some good news to take away from this morbid message. You can likely survive unprotected in space for as long as 90 seconds, which is plenty of time to be rescued!
