Orbits decay, often at a plannable rate. Eventually it crashes back to earth and becomes an archeological relic for future explorers. I bet you could even design the sattelite to burn specatularly (in many colors) on the way down so it's more likely to be seen and sought after.

Orbits only really decay due to atmospheric drag. Other tiny bits of cosmic, rarified gas can slow the spacecraft on a long timescale, and solar radiation pressure can perturb an orbit (occasionally dramatically, if the Sun is unhappy), but the effect is far smaller than constant drag. If a small satellite is orbiting Earth at a high enough altitude which was calculated to consider the broader gravitational system (E…

It seems that peoples through the ages have respected the pyramids enough to leave them mostly intact and undisturbed, giving us the unique heritage that we have today. I can't help but contrast this with the British explorers who just started blowing through it with explosives and pulling stuff out wholesale.

I'm aware that they were subjected to grave robbing. That seems like more low-level thieving than actual organized pillaging though, which required destroying structure to pull off, as evidenced by the fact that the most important artifacts, including the riches of the burial chamber and the sarcophagus itself, were still there until modern times.

Those are called ballistic projectiles, and you cannot place one in a precise orbit. You need upper-stage guidance, admittedly just for the placement of the satellite, but you still need electronics. Though, that being said, I'm now curious how you intend to store large-scale data without any use of electronics.

Let me clarify - you don't need electronics that are effective forever . You would store the data in an analog format.

I was at the Vatican museum recently and was surprised to see most sculptures appeared to be permanently damaged for embedding a number label. (example: http://1.bp.blogspot.com/-hvqlG6iPcP8/UGzso1C3AcI/AAAAAAAAJF... ) I agree with you, let’s not be arrogant, like in the past, and destroy what we should save for future generations.

Is that part of the original sculpture? It looks like a modern pedestal constructed for it to me.

"...for some reason:" - they shouldn't be allowed to destroy such an important monument to satisfy their curiosity.
