Acquisition Day

In the sci-fi novel, ' 8113', Acquisition Day is a celebration that denotes the day an infant born in ultra-terrestrial habitation (eg: the Six Colonies or on Mars), is fitted with an ore-powered battery in the chest and assigned an impurity that becomes the key identification bar-code for that person. It is the day a human becomes a geotomaton, and is celebrated yearly similarly to a birthday. The addition of the ore into the geotomaton assists with low-gravity, low-oxygen, high-radiation survival needed for ultra-terrestrial living, and promotes superior bodily function/healing that significantly increases one's lifespan.
