Decay rates of human remains in an arid environment.

Abstract
The environment of southern Arizona with mild winters and hot, dry summers produces great variability in decay rates of human remains. Summer temperatures, which range well over 38 degrees C (100 degrees F), induce rapid bloating as a result of the accumulation of decompositional gases. However, in certain circumstances, the aridity can lead to extensive mummification, allowing preservation of remains for hundreds of years. A retrospective study of 189 cases, concentrating on remains found on the desert floor or in the surrounding mountains and on remains found within closed structures, outlines the time frame and sequences of the decay process. Remains can retain a fresh appearance for a considerable time in the winter, but the onset of marked decomposition is rapid in the summer months. Bloating of the body usually is present two to seven days following death. Following this, within structures, there is frequently rapid decomposition and skeletonization. With outdoor exposure, remains are more likely to pass through a long period of dehydration of outer tissues, mummification, and reduction of desiccated tissue. Exposure of large portions of the skeleton usually does not occur until four to six months after death. Bleaching and exfoliation of bone--the beginning stages of destruction of the skeletal elements--begins at about nine months' exposure. Insect activity, including that of maggot and beetle varieties, may accelerate decomposition, but this process is greatly affected by location of the body, seasonal weather, and accessibility of the soft tissues. Carnivores and other scavengers also are contributing factors, as are clothing or covering of the body, substrate, elevation, and latitude.

The Genetic Pathway for Programmed Cell Death
I remember having a discussion on one of my forums (can't recall the forum[maybe here?]) where we discussed longevity and cell death rates.
In the discussion we talked about turning off the part of the cell genes that causes the cell to die. I recall referencing a science site that had a chart of decay rates over time once a body dies (it stated the vagina was one of the last parts to die).
There are websites that show scientific experiments tracking decay rates in different environments. It is said, a dead body on the Moon will never decay.
I disagree because everyone that is alive has bacteria in their bodies. On the Moon, within a spacesuit (even without air) the bacteria will still consume the organic. However, after the bacteria die, the decay process would stop.
If a person were to be dipped in plastic at the moment of death, they would still decay inside the plastic but at a much slower rate and when the bacteria within them dies, the decay process would stop. If the bacteria died when the person died, there would be no decay.
It is possible someone might be entombed in a way that prevents outside intrusion. If the bacteria dies fast enough, the outer shell of that person may remain fairly intact.
