Isn’t a much easier way to look around our planet and search for satellites of past civilizations? Or even on the moon where everything lasts much longer. Long after we and everything of us is gone from this planet moon vehicles and other devices which were left there will likely still be there unless a meteorite hit them.
- yissp 6y agoI don't think satellites stay in orbit for very long - like a few decades at the very most.
- treis 6y agoDepends on their orbit. LEO will see drag from the atmosphere and will fall from orbit relatively quickly. Geostationary satellites will orbit basically forever.
- vlovich123 6y agoWon’t solar winds push it out of orbit in a geologically relatively short amount of time?
- nradov 6y agoSome of the Lagrange points allow for more stable orbits so would presumably be better places to look.
- rtsil 6y agoDepends on the orbit. Elon's roadster on its heliocentric orbit has a predicted half-life of 15 million years (1) The moon has been on orbit around the earth for billions of year and will probably remain on orbit forever (whatever "forever" means).

- Frost1x 6y agoI'd say the moon would be an obvious candidate to look at, though no guarantees.
- redisman 6y agoThat’s where you hide the first obelisk
- theossuary 6y agoWell, according to Mass Effect, we should really be looking at mars
