In the series Terra Nova:
The people from the year 2149 send a time capsule back in time. They never find the time capsule (Later named: 'The Probe') that they send. So whatever they do in Terra Nova ('in the past') doesn't change the future because they are in some sort of different time-line if I remember correctly.
So my questions is about the ship/items that they are looking for in the badlands.
Question: How did they know that the ship/items were there in the first place? How did the people from the future knew about those items and told Mira (& the six-ers) to search for them/gather them with the army at the last episodes.
