It's still airing on CTV. Episode 9 aired last night.
And low and behold, the show actually (finally) reveals all about the mission, the project, the purpose, the aliens.. in the episode immediately following it going off the air on ABC.. great timing, ABC :)
Warning: Spoiler! (Click to show)
The alien object was found before the first mars mission, and it is an object they found in South America. Radio Astronomers found a signal going back and forth between Mars & this object on a set frequency. The entire point of the first mars mission was to retrieve "alpha" the object that "beta" was communicating with. As time has went on,they've discovered that Beta/Alpha are talking to 7 other objects all throughout the universe. Through some level of communication, they believe it is imperitive that they pick up and unify all seven objects - which appear to be living - in one place. Pod4 is a giant collection bay of 7 pods, designed to host the 7 objects. One on Venus, one on Mars, Earth, 2 on Saturns Moons, one on a moon of Jupiter, and one on the surface of Pluto (how they'd pull that off would be intresting). What happens when they unify the objects? Not a single person knows, but everyone who runs into the objects feels compelled to bring them together. And everyone hallucinates.. except for the female scientist. Everyone else sees the object as something beautiful. She sees it as nothing, just an empty box, and is somewhat.. bedaffled why anyone listens to it.
