The satellite won't go up, but yeah going into the past for a new PoE seems likely. It seems a tad strange though, we'll either be looking at a current trained assassin who already had ancestors who handles PoEs which is fairly uncommon, or we'll be going through the whole process of bleeding effect again but possibly with a civilian (which is effectively what Desmond was at the start of Assassin's Creed). My guess is we'd use the satellite to do what Juno talked about "thinking away something". For some reason it seemed the First Civ had trouble getting a PoE into the sky for this plan when they wanted to think away the flares, the satellite could be key.

They could of course go down the route of "Juno underestimated what humans are capable of now and got shot to shizzle", but that would draw a ridiculous amount of bad press for unimaginativity. Would open the way for a completely different plot though.
