that
and once again we have live downlink
from at the candle argument
or support team
you
no pieces and then you can proceed in
the Pascal was good
this is Spacelab mission operations
control we are now receiving live
downlink from orbiter Columbia this view
coming from within the space lab module
go ahead for the daily status check once
again we're continuing to receive live
downlink from the space lab module
inside Columbia's cargo bay and the view
we're seeing here is coming from a
camera that is mounted in the aft end of
the space lab module this camera is
looking forward in the module and so we
are seeing the right-hand side or the
starboard side of the space lab module
and just if you point out a few of the
things we're seeing in this view if we
look at the left-hand most part of the
of the view here we see the like yellow
to yellow boxes and what those are is
that is where the Space Lab VCRs are
located those VCRs used to record all
the video that comes from these cameras
that we are seeing we only get portions
small opportunity to opportunities to
get this video downlink and so those
video recorders are used to record all
the video that those cameras take and
then moving more to the just to the
right we see the bubble drop in particle
unit unit experiment that again is one
of the facilities that is uses the crew
to load the different test chambers and
initiate the test runs and then the
experiments are the test runs are then
remotely commanded to and operated from
here on the ground at Space Lab mission
operations control and further to the
right almost directly in the center of
your screen in the green-colored rack is
what is that is where the astronaut lung
function experiment is located again
that experiment is studying the effects
of weightlessness on the human pulmonary
system and just on the bottom left-hand
side of your screen you can see one of
the crew members this particular one
being payload specialist Bob Thirsk who
is performing activities in the torque
velocity dynamometer which is located in
the center aisle of the module
dr. Douglas what of mcgill university in
montreal is the chief scientist behind
the tree experiments his devoted as
careers trying to understand how the
vestibular system or our inner ears
balance and orientation Center how its
functions and how specifically it adapts
to a weightless environment the idea for
the torso rotation experiment first came
to dr. watts several years ago when one
of his colleagues suffered an injury
that required the wearing of a rigid
next place the colleague mission to dr.
Watson after a few minutes of walking
around on the laboratory began to
develop symptoms of nausea muscle
location is a term that we use to
describe a person who rigidly fixes
their head to their torso and such that
when they have to turn their head to the
right or to the left they have to turn
their whole torso as well what's the
rotation is example of an abnormal motor
strategy in which the subject
concentrates on a body frame of
reference rather than the external world
and this causes us to suppress the
normal way that our vestibular apparatus
in our brain likes to operate another
good example of suppressing the normal
way that our brain and vestibular system
likes to operate is someone who's trying
to read a book inside a car that is
moving down a twisty country road ball
would be bumped around all over the
place of product focus on the books when
really our brains and our vestibular
apparatus would like to make reference
to the X the world at that we see
outside the window and as you know
several people who try to read books
inside moving cars become motion sick as
well what is interesting to dr. wat is
that astronauts tend to inadvertently
develop a torso rotation motor strategy
as well during the first couple of days
of spaceflight and we probably do this
to try to minimize our symptoms of
motion sickness but in fact we might be
exacerbating the symptoms the doctor
Watts torso rotation experiment study on
the life and microgravity Space Lab
mission we are going to be measuring our
eye movements with special electrodes
that we apply to our faith
the special velocity rate center that we
rigidly fixed to the top of our head it
also will be measuring our torso
movements as well with the special
backpack accelerometer which is fixed to
our back after the flight is over dr.
what is going to compare our eye
movements to our head movements and our
head movements to our chest movements
and he'll be looking for any evidence
that we might have adopted some torso
rotation motor strategy during this
flight will be doing this experiment was
early in the mission we've already done
it exactly towards the middle of the
flights a couple of days and again
towards the last day or two of the space
mission if it turns out in fact that
we'd have a dot to torso rotation motor
strategy during the flight which might
cause symptoms of motion sickness
that'll be relatively easy to train
future astronauts to avoid this type of
motor strategy or to pre adapt them to
the atypical movement environment or in
a ground-based laboratory prior to
flight well that's what the torso
rotation experiments is all about if you
see us in downly video over the next few
days wearing strange-looking apparatus
on our head or on our chest you know
that will be just checking out to see
that whether or not we are trying to
unconsciously suppress the normal way
that our vestibular apparatus likes to
operate well that's it today from the
space shuttle columbia tune in tomorrow
to learn what are the other exciting
elements investigation goodbye
now in view of from Columbia the outer
banks of the Carolinas I'm you're moving
out to bed the Atlantic Ocean
