When they sent a kino through to the locked out planet, it appeared rich with life; we don't know why Destiny locked it out, but obviously the seeding ships decided to place stargates there, and Destiny (with more recent information?) still decided it was unsafe. I think it's reasonable to think that Destiny scans them in some way when it approaches. For all we know, she does a flypast and then dials, and the locked out planets were ones she was in battle over or something...NecronLord wrote: There's really no need. The scout ships ahead of Destiny are choosing the planets most apt for stargates, and that data is probably relayed back to Destiny. Even if the crew can't access it, Destiny already knows what is and isn't habitable. It doesn't need to use its own scanners to determine habitability or appropriateness.
Of course, it's all specualtion still, but I think the fact that Destiny has locked out certain planets indicates that she's aware of what's on them in recent times, as the locked out planet appeared habitable at first glance.[/quote]
On the other hand, Destiny could just be making an executive decision of "they need materials to breathe air, this is the only planet for that so that's where I'm taking them", rather than having some kind of updated data.
I'm sure the crew would note if they were dropping out into star systems and getting close enough to run more detailed scans of worlds. I don't remember Atlantis getting detailed data from planets from outside the star system, which means the ship probably would need to be in system. It's much simpler to assume Destiny knows what the crew needs/wants, and locks out all other addresses because it doesn't want the crew dicking around on worlds that won't give them what they need (and it probably isn't smart enough to figure out that these people don't actually want to be on this joyride).
