NDC cremates their fallen and turns the carbon from their ashes into graphene orbs. This has a bit of soil in the bottom from where they either died, or from their home. At the top of the orb is a small data drive with a list of their accomplishments, or a final pre-recorder audio message. In the center, is a holo of the person's face, and their name is inscribed in the surface of the orb. It is then placed in the memorial walls that are in the center of the central park of the capital, or where ever a colony has placed their's. All the additional carbon in the ashes of the dead is used to make armor, small items, or even jewelry for next of kin, or remaining family to hold onto in memory of their loved ones. As well as to pass on to the next generation, which in the case of armor, may even result in a full suit that is passed down as heirloom, and priceless family treasure. About the same goes for the other items too.
