The trailer was the real thing.
I'll put Daniel's criticisms aside and not discuss the NASA equipment. I'm no expert on them. :) But I will note that the trailer on the official website says that the thing is the "Beagle 2 Mars Rover". I'm not sure what it said in the first copy of the trailer I posted.
You know, thinking about it again, it's hard to imagine Steven Spielberg and Michael Bay attaching their names to a poorly made movie. This gives me some reason to hope that it will look better than the Power Rangers TV series. But I'm still not holding my breath. :(
