taxi here and today if you know we have
here John Dillinger there's a student
with the chicken embryo determine and
sponsor here mark duty who represents a
Kentucky crime ticket and we appreciate
all the support the crew gives us and
we're happy to have the sponsor and the
students here with that I'll turn it
over to you John and you can tell us
about your experience well I'm very
excited to be here because it's really
one of my dreams I've been working on
for a long time when I started out in
the ninth grade I thought to myself
imagine this chicken egg in the back of
the barn yard gravity's causing yoke to
fall to the bottom of the egg that a hen
has a natural instinct of turning over
that egg around it's there for the yoga
fault go back up to the top and gravity
pulls it back down to the bottom again
now what would happen to that egg up in
space when you don't have gravity
pulling that yoke down to the bottom how
would that embryo develop from that
basic basic hypothesis I developed a
little broader range of what I'm trying
to accomplish with my experience
experiment since the ninth grade I've
gone into what I consider four key areas
of science that I'm looking for the
first one is embryo development can we
maintain embryo development up in space
can-can an embryo develop up in space
you know we can grow a better crystal in
space is Earth the best place to have
children the second area of interest
that I'm looking at my project is one of
bone calcium and I'm sure you're all
aware of the bone loss that astronauts
experience up in space for when they're
up there for an extended period of time
and what I'm going to do with my
experiment is look at the mineralization
and a demineralization process of the
bone development and see how the
calcification process occurs within the
developing embryos of the chicken egg
the third thing that I'm going to be
looking at is what I call production
performance I'm going to actually let
some of the eggs hatch take them through
the launch
the space environment the landing and
see what results okay can we have and
they go through that type of environment
and hatch what type of chicken is
produced after it's been in that kind of
environment and we can compare we can
compare and see okay does it does the
bird grow faster what type of blood
quality does it have the semen
production and all kinds of different
areas of interest that we can look at as
far as the production performance is
concerned another area that we can look
at is what i'd like to term the inner
ear that's one that's responsible for
your equilibrium and your motion
sickness and we're going to look at the
inner ear of the developing chicken
embryo you see okay what kind of effect
does this weightless environment have on
the developing embryo and how the inner
ear develops to obtain the optimum
amount of data from this project I had
to divide the age of the eggs into two
groups it takes 21 days for an egg to
hatch there be 16 eggs there are two
days old maybe 16 eggs that are nine
days old all the studies I have two
identical hardware units all the studies
will be done on a comparative basis the
only variable that will be different as
a weightless environment of space for
this project I've composed a team of
seven of the top scientists in their
respective field two of them are from
Purdue where I was from Tulane and and
14 of them from Boston University they
serve as my scientific advisors for this
experiment as a mechanical engineering
student I enjoy working with the
hardware and the hardware we have given
you all a folder and where we have a
hardware we have outlined what we call a
hardware description and I could let
would just like to take you through some
of the things that we've highlighted in
that report and explain to you why the
hardware is here and how it works the
first thing we have is what we call the
ecs is our environmental control system
what this is composed of is we have an
on-off controller it hooks up to the
shuttle 28 volt DC power the controller
is on the back side of the front plate
we have five silicon rubber heater
strips the on-off controller functions
in conjunction with the silicon rubber
heater strips that produce the uniform
temperature by locating the heater
strips in that location and by putting
the fan of having to act like a ceiling
fan we've created uniform temperature so
that all the eggs are seeing the exact
temperature we have what i call a
humidity control system which is down
below the fan on the bottom i have what
is called a humidistat that senses the
humidity on the inside of the incubator
and it's an on-off controller when the
humidity gets over a certain level it
turns on an air pump located directly
below squirrel that air pump circulates
air through a desiccant tube so when the
humidity gets over a certain level the
humidistat turns on turns the air pump
on circulates the air through the
desiccant the moisture is removed and
when the air humidity in the air gets
below the desired level that it'll shut
off and it will maintain a uniform
humidity because what we're trying to do
duplicate the conditions that the hen
provides in the back of the barn yard
and the normal humidity would be
sixty-five percent and a temperature
would be 99.5 okay I've put in a time
line within the crew integration the
time line starts when we load the
incubator in the laboratory the first
career interaction would take place at
24 to 30 hours the first thing we want
to do is what we call a unit operations
check and that's nothing more than
making sure that the switch is on that
the power on light is on and just
checking the system out to make sure the
fan is running the system is running the
second thing that needs to be done is
temperature and humidity recordings now
this will be done with the squirrel
meter longer and as you can see there's
three buttons on the squirrel million
logger a B and C like I've outlined in
the integration plan
button a will be pushed once which will
bring up the display if button a is
pushed again and I have to be pushed the
second time it will come up and it'll
say 21 and there at that point in time
this first temperature can be recorded
when button be is pushed there's four
channels because there's two humidity
probes and there's two temperature
probes and once you put push button a to
get it to channel 2 and then button be
will be pushed to switch from channel
from the first temperature second
temperature first humidity second
humidity and that's a continuous cycle
you can sit here and push button be like
for example there's humidity there's
humidity temperature temperature and you
can just go around the clock rotating
temperature and humidity before just by
pushing button number B button number C
will not have to be used at all that's
de strictly to program the squirrel meat
logger oh yeah are you manually
recording the temperatures or is it when
you say you record the temperature
you're you're actually recording it in
your squirrel meter right as the neg
develops the response wash so therefore
as the mission increases the amount of
oxygen consumption increases that's why
the crew interactions become at a closer
interval towards the end of the mission
whereas at the beginning of the mission
it's not the incubator does not have to
be attended to quite as frequently
because of the oxygen consumption the
eggs are getting larger required more
oxygen so I had the crew interaction
what you have to do is open up the hatch
door this is done just strictly by
pulling up the airplane fasteners
removing the hat store it's tethered 10
what I call capillary pads the first pad
will be removed at the first crew
interaction the pad will be opened up
and exchange this will be this packet
will be airtight and pre charged with
about five CCS moisture the pad will be
exchanged this one will be taken off the
back of the hat store put back on the
side and the fresh one we takin off open
up and put it on the back of the hatch
store after the five minutes the hat
store will be put back on yeah
and is it going to affect the moisture
content of that if you I assume you
prefer to leave the putting the ad until
the last right right just before you
right close it up before the before the
hash stores closed back up and then what
that will do is that will recharge the
system with the right amount of moisture
and then the humidity control system
will compensate if it goes over you know
goes under that will keep it in line
it's all humidity you're trying to
maintain a 65 person right what the legs
doing Houston 80 any questions that
you'd like to ask her let me ask a dumb
question Jenna I'll get it from the kids
if you put the eggs in two days before
launch right where do you get the eggs
man well we have we talked in Florida
eggs yeah we're talking Florida eggs
what happens is there's a lot of
districts involved in trying to have two
different age group of eggs we have a
supplier to kentucky fried chicken at
live oak florida which is called cold
kiss hatcheries and they have rooms full
of eggs probably the size of this room
right here and what we will do is we
have them set back eggs like starting 10
days before the mission so that they
have eggs at every day from ten days on
a case there be any kind of delay and
what we do is we have designed and built
a portable generator an incubator system
to carry the eggs from live oak florida
down to the cape then we'll load them up
in hangar l and it'll be loaded like 12
2 hours prior to flight what you wants
to record the temperatures and humidity
rights right before we open it right
would it not be interesting since you
really don't know what's gonna go in
there to record them after you close it
sure so yeah that would really want
understand how the brain works from the
engineering strike point you really
getting right here for how much mass
exchange right that'd be great and I
just mean as long as you're right in the
mini when there's that when this way you
all right i mean i don't know it's
probably not i mean as long as you're
doing it channel 2 second temperature
channel 3 first humidity channel 4 2nd
humidity third channel that is that is
if you want to play back at that's
that's something you don't have to worry
about this kind of get a feel this was
from a previous testimony right in other
words that's all the temperatures that
the incubator would be seen that's the
time now we call on the column first
number to a channel and then the motive
yeah samode this would be a modem this
video's Netanyahu channel them yeah you
go modes 13 17 angles would have one
through four actually there's nine modes
yeah there's nine okay yeah those are
kinds yeah tues on Jeffrey's on Channel
Four's on but that's even open your
thickness that'll be will have that done
before we start and then first channel
it'll flash off and that's all right
it's all so sure do it you're no idea
tree again before you turn it on kid
right did you know go on channel
whatever the write up is always right I
did it again that's really hard right
well what you want to do is once you
call it up then you want to push it
again otherwise just gonna disappear go
ahead try it i think you get a better
scoop you gotta drink
now you gotta hit it wallah just play
again right in Christ chance if we could
build no but I what's the best I was mad
as I say the hand on a step include man
right I don't know right one phones the
now see go ahead and push that again and
you see it goes back to channel one yeah
you could yeah you can all this will
sound pro right right you just won't
disappear right exactly once you get out
of mode 1 it's gonna stay whatever motor
ever and you see that piece of velcro
would be going this way right right dope
on the outside of the leg and then
there's about girl on the sponge exactly
this one does not happen because we want
to save the anessa proof help grow any
particular wine this region not really
what we've done and we can maybe market
if you guys would prefer but we've put
that towards the bottom corner the other
yeah you know you were in lung
concentration yeah we thought you wanted
them where no it's just it's just
thought you know just to keep
consistency I guess okay
we won't change that sure I'll just tell
you yeah we anybody at any time and no
knows we're floating right we see that
red line off right that's right exactly
