let's talk about SPACE MUMMIFICATION!

If you were to die in a nice, warm spaceship due to depressurization, the lack of air pressure would cause water to boil at room temp.

In time, all the water in your body would boil away, turning you into a leathery prune.

Ancient Egyptians managed this process by way of a dry climate and a host of salts and other chemicals.

They might have been able to save some effort by merely developing a cost-effective method for space travel.
