After a long wait for the crew (and audience!) STS-92 is finally here. We'll be delivering the heart of the ISS external structure, the Z1 truss, as well as a new docking port, PMA-3. Along the way we'll learn a bit about the folks on the ground who make this all possible, walk through four complicated EVAs, see something no one's seen since 1967, and put our plumber's hats on.
