and Houston disorient you we're starting
at six o'clock we're going around
clockwise to show you the markings
leonarda's our perception that there was
no movement of the hatch when we
repressurized back to 14.7 thank you
tammy
just in Columbia as you saw we walked
around slowly throughout the entire
hatch perimeter we can't detect any
displacement rider leash and we
certainly see no gross motion as
measured against the markers and we put
around the door yesterday in Ted 2 so we
don't have any Delta's to show you any
other things that you'd like to see
ok we are full close that is in the
direction of closed and now I'm going as
far open as the handle will go easily
and now i'm going to push those extra
couple of degrees or we really come to a
hard stuff
okay we really appreciate that Tammy
yeah close to us yeah that gave us a
very good idea of what you had told us
in words a couple of days ago so we
really appreciated that and that
concludes our our requirements for for
downlink of of the hatch thank you very
much I was excellent you're welcome okay
used in the Columbia I did the first
series here on the Cape and we'll start
now with the b3 setting on the power
tool it was very easy holding on to the
handrail of the hatch minute like the
tool through the b3 and b4 settings
there was only a slight amount of torque
applied with a size know it all the way
down to the hard stuff we copy and you
have to watch us run through the series
but the basic finding at b5 was that the
body position was disturbed quite a bit
by the b5 hard stop force and b6 and b7
well attempted really swung the body
around to the point where the tool was
hopping off the bolt or you could not
hold your body position in Houston
always still have a few minutes sku I
can just say briefly that we all sound
very similar results that the b3 setting
corresponding 25 foot-pounds was
certainly acceptable as was before but
we get to be five settings 15 foot
pounds that's a fair amount of force to
react through your wrist b6 again we got
low torque readings indicating that we
let go of the trigger early and if we
have enough time in this K you down like
you'll see when i get to that setting my
body will get spun around much like toms
did
one thing to think about when you're
setting up your test is as Tom mentioned
was that we will be on umbilicals
handrail position is very important this
handrail position is not ideal a
handrail on the floor would have been a
little bit more comfortable when
reacting the higher torque and we're
wondering if we have enough clearance in
the mid deck in a suit without our legs
contacting the walls and by seeing the
data if you're truly looking for us to
hold the tool and react all that torque
through the wrist and not use our body
in any way as previously briefed before
we flew we copy all
is this story up my data came out of the
same as Demi's it pumps basically up
through while 15-foot bounce we're very
well I'll be on that in this particular
unsuited environment it's not reasonable
i intuitively think that this is going
to go a whole lot better when you're
suited because instead of having 160
pounds of body inertia you have about
480 pounds help us stabilize the body
when the tool reaches its final torque I
also intuitively think that a gloved
hand is going to hang under the pistol
grip a lot better did the bare hand does
it is also a lot more strength and
stability at least ability India the
wrists and arms of a suit so I didn't we
think it is gonna go lot better than a
suited situation we copy
space shuttle Columbia astronauts Tammy
Jernigan and Tom Jones are with us the
two of you thanks for letting us be with
you in the middle of your day we can't
start without talking about the fact you
didn't get to go outside and conduct
your spacewalks everybody on earth is
talking about it what went through your
mind Tammy when you tried to turn that
hatch handle and it didn't work I was
certainly surprised that the handle
would not rotate as I had trained for it
to rotate certainly was frustrated and
so we tried to rotate a little harder
and Ashley end up working for a couple
hours trying to get the hatch open so we
were certainly disappointed but also
thinking that there was a lot of time
left in the flight and we knew that the
ground team and the crew would work hard
together to perhaps think of a
workaround yeah Tom you got into the act
after that in that very cramped airlock
with Tammy what did you think the
problem was well this way I just thought
we had a sticky hatch and the fact that
Tammy's initial rotation wasn't able to
free it up was just an indication that
we'd have to put a little bit more elbow
grease into it she certainly tried and
then asked me to give it a shot that I
wasn't able to budget either and we were
both putting it putting out about the
maximum force we ever tried to put in to
a mechanical systems in our water tank
training back in Houston and said that
point I started to think that we had a
jam of some sort that our strength
wasn't going to be able to overcome and
say during those two hours in the air
lock while we juggled our bodies around
and tried to find it more mechanical
advantage I was also thinking about
perhaps coming back the next day of
trying this with their support strategy
what were the two of you trained to do I
guess let's start with Tom on this one
in case you were able to get the airlock
open but then you couldn't get it to
seal completely when you were finished
with you spacewalks well we had physics
working for us in that case once we got
back inside the airlock after dva the
airlock glides up against it's filled
with a very easy motion
turning the crank handle merely engages
some mechanical dogs that hold the hatch
mechanically tight but if we could get
it close enough where it would actually
touch the seal as soon as we let air in
from inside the orbiter cabin and that
air pressure would slam that hatch shut
up against the seals and it would stay
closed no matter how strongly we pulled
on it so we were pretty confident that
we would be in a bad situation but
there's always a potential and trying to
get her without mechanically with some
of the things we are on board that we
might damage or what the hatch such a
way that those fields could be damaged I
think that's the conservative approach
that the soul program has taken here
they didn't want to damage the hardware
for the objectives of their CDA which
could be rescheduled the throne of a
later flight yeah that's the question
that a lot of people have now what are
the two of you going to do about your
training as a space station construction
workers that's the best place to do that
is out where the space station would be
outside in the in the cargo bay or very
near it what do you think it's going to
mean to you and enter the overall
program is a the failure of the hatch to
open slowed down Space Station
construction even by a little bit I
certainly think there was interest in
conducting these two eda so a lot of
time and effort put into building the
hardware and orchestrating the test plan
so that we get tests all this hardware
in our concepts for station construction
and so certainly it is a bit of a
setback however there are setbacks in a
program its ambitious is NASA space
program and NASA will figure out a way
to get the information they need to
successfully construct the station
decide where they fly in a later site or
then they use some more extensive ground
testing to get the information they feel
don't need but they will certainly take
the steps to ensure that we have enough
knowledge to have a successful station
construction and maintenance program
sure well the two of you God let me just
add that we select the last ten months
training extensively for these two
spacewalks and a lot of the work that we
did underwater in Houston and onboard
the LA live training aircraft down there
as well they spent validating the
approaches and the techniques that we
would use here
orbit and to a lot of magic said we have
a lot of confidence those techniques
because we worked so hard on them on the
ground so I think the final icing on the
cake and the final conservation hero
that would have been really valuable to
us that certain we've learned a great
deal allows not a tent but just in the
developmental and practice what we've
got ahead trading for the spacewalks yes
the two you're making the best of this
course and we've been watching you test
some of the space station tools you're
going to be using when you build the
station later on how do the tools work
in the tests that you've conducted on
them over the past couple of hours so
the ISS tower to list has preferred
performs well and as expected during the
tests we did on the mid-deck and we were
able at least to fulfill some of the
objectives for the flight by doing the
power tool check out and then swimming
that data down to the ground all right
demio I've talked to Tammy Jernigan and
Tom Jones at several times over the past
couple of years and you know maybe it's
my question maybe my questions are
bummer questions for you guys but the
two of you despite the fact that you're
always optimistic and almost bubbly
seemed pretty much subdued as we talk
right now am i right about this or is it
my questions leading you down a very
serious and somber path today no I think
certainly that we are feeling some
combination of disappointment at the
failure of the hatch but yet pleasure in
being part of this mission has been in
every other way very successful and
we're both technical people and so when
you ask us the technical question you
get a technical answer I'm glad to see
some smiles from both of you Tom any
final comments he's only got about a
minute left well disappointment
naturally comes into our feelings and I
hope for better times on future missions
where I've assigned to a spacewalk be an
optimist about that too but you can't
take away at a fabulous nature of this
experience and personally last night
even after ed A's were canceled I spent
an entire night orbit of yours
looking down at understorms and added to
southern constellations and watching the
lightning flicker out the surfaces of
the orbiter and that's such an
experience that is unreachable on the
globe that I'm very privileged to be
here and I have no basis for complaints
you
