Etch it onto a metal disk like this[1] inside a capsule that can survive reentry, pay to have it shot into space with a slowly decaying orbit. Then perhaps arrange to have the reentry hit a pond near your ancestral home in about 500 years time.

- kadoban 5y agoThat's got to be ~impossible by today's engineering. Hitting a specific place or even decaying at a specific time in 500 years is just never going to happen. It'd have to be an active process, which means you need a machine that's still running in 500 years. Even then I bet it's still a hard problem. IIRC NASA aims for like, an ocean and they're happy if they hit the right one.
- influx 5y agoThe Minuteman III is an American ICBM that is accurate to 800 feet. Much closer than hitting an ocean.
- grey-area 5y agoYes the last bit was just a little joke - orbital decay is subject to too much uncertainty. Although I guess if you had propulsion you could deorbit in a specific place at a specific time. SpaceX and icbms deorbit precisely so we have the technology nowadays to do so. Maybe an ion drive could last that long?
