Now you're imagining things too. Assuming you're referring to the Feb 17th "This Week at NASA", which has the grade school students and a girl using a simulator (at 2:45), that is most definitely
not Orbiter she's using. See for yourself:

They are not the same. First off, the ISS is clearly different, so we can discard that
Let's look at the Orbiter. The heat shields are different hues (the NASA one is paler), the nose gear door is completely different, the area just behind the hatch is very different. Orbiter's textures also appear to be higher-quality, with fewer artifacts, and the texture on the bay doors is very different.
You guys are looking at two different representations of the same thing and saying that one looks a lot like the other, when in reality they're just close representations of the same thing.
Out of curiousity, where are the Orbiter textures from?
