CHRIS CASSIDY: Here we have a view of the White Room
itself as Scott Kelly prepares to put on his harness.
There's Scott climbing in as he pulls himself and slides
himself over into the left-hand seat, which is the commander's seat.
In the middeck we have Alvin Drew, who is MS-5 all the way on the right-most seat on the middeck.
Dave Williams is suiting up now in the White Room. George,
now we have Charlie Hobaugh in the screen in the White Room.
He'll be the next one to ingress as he heads up onto the flight deck next to Commander Scott Kelly.
In the White Room now is MS-1 Tracy Caldwell.
She's getting her harness on and getting prepared for her turn to ingress.
Charlie Hobaugh has climbed into the flight deck in the
pilot position and Dave Williams has ingressed into the MS-5 position.
George, entering the White Room also with Tracy is Barb Morgan. Barb, of course,
has had a long road to spaceflight as she was Christ McAuliffe's
backup prior to the Challenger incident,
and stayed in touch with NASA as she was back in the classroom for a number of years,
and then had the opportunity to join the astronaut class of '98,
where she began both training full-time as an astronaut and living in Houston,
training in Houston. Here's Barb Morgan entering
the middeck as she climbs up and into her seat, the MS-4 seat.
Here's Tracy now as we're looking down from the front part of the cockpit, looking aft.
Rick Mastracchio now has room in the White Room to begin his suit-up.
Rick Mastracchio climbing in MS-2 spot right there in the center
second row on the flight deck. He's the final crew member to ingress.
No other crew members remain in the White Room.
GEORGE DILLER: So, Chris, with the hatch closed here,
there's a few things I guess they have to go through to be sure that it's secured. Is that right?
CASSIDY: Absolutely. It is a pressure vessel inside there,
so when you make that final hatch closure, you're sealing off the pressure vessel and,
as such, you've got to make sure that the seals are all intact
and there's a period of time where we'll monitor the pressure,
and make sure there's no pressure drop across the hatch seal.
