Space Station

I have never watched a "Big, Bigger, Biggest" episode, but watched this one specifically because it was about the ISS. The documentary has a good mix of interviews and action shots with some good graphic illustrations thrown in. The "level" (of at least this episode) is aimed at the general population, thus concepts are explained in simple terms, suitable for 12 years and up I would say. For anyone who knows a bit more than the average person about the ISS, this probably doesn't offer anything new. Interestingly though, the scope does not just include the ISS, but every other "space station" that came before it, with the connecting thread being that each successive space station mastered yet another challenge, culminating (so far) in the ultimate space station, the ISS.
