I
hey good morning I'm Sean spreading from
the space shuttle Columbia mission
specialist number three them standing in
front of today an experiment developed
by dr. Reggie Edgerton at UCLA le
laboratories it involves measuring arm
wrist and hand straight it is well now
that in space over lon joist the time
our muscles in our bodies go weaker it
fell however that the hand in wrist and
arm muscles stay essentially the same
here for Columbia myself and my
crewmates are going to actually measure
exactly whether or not this is true this
device I have in my hand right here
accurately measures our hand wrist and
arm strength its plight allograft here a
given a a curve which we can exactly
duplicate over time we measure this pre
flight and four times in flight and
post-flight basically involves grabbing
Sahay grip dynamometer and squeezing in
various levels of contraction ranging
from tis a hundred percent visual later
plotted out on curves that were asked to
follow in graphs as spike and were asked
to trace these this will give dr.
Edgerton it is assistance all the data
that they need to actually measure
whether or not the muscles and our
wrists and arms continue to stay the
same or grow weaker thanks for joining
us aboard space shuttle columbia today
and we'll be continuing with some
examples of muscle involve experiments
in the succeeding days thanks
welcome aboard Columbia and SPS 78b life
sciences of microgravity Space Lab lms
for short my name is Rick went ahead and
I am the NS one of the flight and this
is a short for askin our lung function
experiment now alfie is the brainchild
of dr. john west and elliot and kim
frisk from UCSD University of California
San Diego and it is designed to measure
the physiological processes of gas
exchange in the Unimog on earth and a
space or free fall now there are
discrete differences which will occur in
space and there are four payload crew
members who are participating as well as
your crew members in our experiments
throughout 70-day LMS flight and what we
hope to ascertain from these experiments
is how the gas flow rate in the law
changes due to microgravity or free fall
in terms of how gas dissipates or aligns
itself in the lung now when we learn
things like this be able to predict how
the one will function obviously in space
and we can use that knowledge to
determine hopping should function on the
ground and with this information we get
also hope to understand various
topological processes which occur in the
human lung saw different diseases so
that we might be able to study when we
have better controls additionally will
use this information for long term stage
in space on the space station and
hopefully a long-duration spaceflight
maybe one day to colonize the planets
all this information will be put to use
in one way the other for long-term
spaceflight and stays on space now this
rather debonair suit that i'm wearing is
now called the mark 1 mod of the RIP
suit and rip basically it's a
respiratory plasmid to graphene suit
which will measure our ribcage and
abdomen contractions and expansions
while we breathe and this is measured
over on our optic ATT here and with that
signal that is rotted to the ground the
key is elliot dr. Westman dr. Chris
we're able to determine differences in
how we
and our chest muscles function in space
when we breathe it's a very very
important experiment and were the best
experiments I believe to fly on the SLS
series flights we're going to get a lot
of today from it and I'm really excited
to be able to participate in this
experiment thank you
thank you much I'm delighted to be
speaking to you today on occasion of
Canada's 120 ninth anniversary to you
your excellency governor general
applause to the right honorable Prime
Minister taken to my fellow astronauts
to all the other distinguished guests
there today in to all Canadians sure
booth on voir to made my yuzu I LoCascio
to solve and new Kia money besaid to
Canada actually are not that far away
I'm 280 kilometers but straight up and
in fact the last time I looked we were
just about to head over Y which from my
perspective is not that far from Ottawa
this lease for the air do represent a la
canada or send a septic a cheap aaj ki a
group days are made from C to a a 10-1
debris alerts provide an occasion
astronaut program as well if has the
same that the spirit is my group of
Canadian of my group of astronauts here
on board the life and microgravity
Spacelab mission I'm proud to be a
member of the Canadian astronaut program
and internationally they're also quite
well respected journey trick miss then
one in the Canadian astronaut has
recently been selected for a payload
specialist flight sudeep I and Steve
mcclain are recently announced mission
specialist candidates and Dave Williams
has recently completed his mission
specialist candidacy is now eligible for
flight assignment
I'm living in a incredible extraordinary
experience on board the space shuttle
Columbia this is probably the highlight
of my career as an astronaut and of my
personal life as well I feel very
privileged Marc Garneau who is there
with you today can tell you all about
that Damone post Allison abdomen adepts
she was and grampa tree to Canada off a
cemetery buchla male built the wizard
Toronto a Ottawa she say Callum a POF a
bow or should we laugh say dog the
privilege to sweat theatre they can add
ya doin boo I'll open to pay during
sleep as depth ar-15s you yay and I
believe I have the best seat in all the
house to wish you well for my view here
from Canada from coast to coast I share
with you all the pride and joy of being
a Canadian on this can of the day I like
to thank all the organizers of the
Canada Day festivities and now I'll turn
it over to Governor General Leblanc
columbia this is a WBBM how do you hear
me study BPM rod clear we're ready for
your questions tell me about your can
you're conducting medical tests up there
and scientific experiments if you might
give me an outline first of all of what
kind of science experiments I understand
you have a lot of critters up there rats
and fish and such grand study but
they're taking a backseat to the primary
life science experiments which are the
human experiments we've got four people
on this flight that have volunteered to
dedicate their bodies to science if you
will and ever since we launched it
before then we've been taking data on
these guys from start to finish they've
been doing some circadian rhythm studies
which means that their body temperatures
have been measured and their sleep
pattern to be monitored addition they're
being monitored for their moods and
their work performance on top of that
these guys are also giving blood and
saliva samples to contribute to a
metabolic studies which are very
comprehensive and really complete
they're on top of that without a lot
function experiment which is helping us
understand the mechanics of the log in
the very basic sense we get some data up
here in microgravity that you just can't
do on earth as far as that experiment is
concerned and actually all seven members
of the crew are participating in that
experiment and one of the workhorses of
the life science aspect is to talk
velocity dynamometer there are four
separate principal investigator teams
that are studying the musculoskeletal
system and everything from very basic
muscle function studies everything down
to the microscopic level these guys have
had biopsies on their legs before and
after the flight and with all that
complete data on the muscles were going
to learn quite a bit about what happens
to muscular structures as we launch into
space and stay there for extended
periods of time and that's a life
science aspect would you like to hear
about the microgravity side well tell me
a little bit more about the the reason
you're doing that in part is with
conducting a lot of these studies is
because of the concern about atrophy
when you go up into space you don't have
gravity so that that you
problems than with your muscles were at
least the potentiality for problems is
that right your muscles up here it's
really not a problem because you go back
to some gravity field to try to stand on
the surface and on the soul side we
haven't had many problems per se because
the solo missions themselves don't
really last more than two or three weeks
and that's not enough time to get
capacitate anybody it is today we're
also doing exercise up here to prepare
for the return to Earth what's the most
interesting part of that question is
what are we going to do when it comes
time to travel the bars and the trip to
Mars as we currently have it scoped out
it's going to be approximately one to
two years and that's quite a bit of time
if you would like to get out and walk
around on the surface of Mars when your
spaceship arrives you've got to make
sure that your muscles are in good
condition and that's what we're trying
to capture with these studies or
preventative measures in order to
understand how we can do things in the
future to keep people from being
incapacitated for long-term space travel
