That I don't know, but it is a "full-scale mock-up". It's not like NASA is
going to let a bunch of elementary school kids stick their grubby little
hands on actual flight hardware. ;-)
Surely this is a bit of marketing in the guise of education, which I think
is a good thing for NASA. The pop news media certainly isn't educating the
public when it comes to space.
