you
good morning Atlanta is planning ship is
here with you how you doing today good
boy Houston nice to hear your voice
we're all with you okay Ken and we have
some work for you today I hate to get
you started so early but if you could go
on up to spec 20 the forward Jets are
getting a little cold we'd like to get
some firings on them but we need to
select a three on the dev so that would
be an item 1 plus 3 that'll tighten the
dead bands and get us a couple of
firings
Houston Atlantis with answers for the
head of that questions okay we're ready
for the internet questions corrected
Tyler bulky htn for Grand Rapids
Michigan as a pretty confident and what
ways is the MIR space station better
than the space shuttle and we started to
try to come up with the list of ways and
then realize what you would really be
comparing our apples and oranges are
really two completely different vehicles
here of course was designed to stay on
orbit for a long time and it's
approaching nearly 10 years old orbit
the Space Shuttle was designed for
frequent trips to at that space caring
and fairly large amount of cargo so to
say beer is better than the shuttle in
some ways is only true because it does a
different job so for sale in orbit for
very long time near does have advantages
if that is expandable they can change
the configuration much more living
volume in fear that we do it the shuttle
also totally restored would say they say
we taste not have to carry liquid oxygen
and hydrogen to generate electricity on
the other hand the shuttle has
advantages at being able to carry large
payloads and a large number of people to
a problem a low-earth orbit it's also a
reusable space vehicle so they're just
decide for two very different purposes
so comparing them is perhaps are not up
not something that's very easy to do
okay bill we copy dad won't pass that
along thanks very much ok the next word
is for bill bill derbyshire age 40
Aberdeen New Jersey bill and asks why we
throw away the external tank he writes
it seems a waste to throw away the ET
just as you attain orbit would
make sense to at least parts of the use
tanks and save this valuable resource
for future visions and while certainly
we hate not to conserve all the
resources that we can in order to park
an external tank on orbit we would have
to be able to circularize its orbit
which would mean either carrying it all
the way to low-earth orbit with the
shuttle in which case it would remain it
or in orbit with Charlotte would
ultimately be a hazard to other vehicles
also without self-contained propulsive
devices its orbit would serve decay and
it would reenter anyway and then also
even to another alternative would be to
have a self-contained propulsion device
on the external tank in which case it
could circularize its own orbit but in
idiot k any case the cost to do that
would probably be significantly higher
that the conservation of resources we
would realize by keeping the excel tanks
a little bit okay bill would copy that
also well first thank you
and all our staff with a third one here
from Jill Davis Carl h12 Scott Air Force
Base Illinois yes how many hours of
sleep two astronauts get call it space
is the sleep wrestle how long did your
body's take to adjust to be a Christmas
before being able to sleep well the
number of hours we sleep berries just as
it does on the ground during this side
we've been scheduled for between six and
eight hours of sleep and we've had to be
so busy up here that we get that we do
get fatigued so the sleep Israel and
we've been able to sleep since the first
night we're up here
vanished minus Houston were two minutes
to LOL and we'll pick you up ten minutes
later on the other side should be an
Emmy team about 33 35 Roger that and
that's an MIT of 33 35
Atlantis you have a go to swap to the be
water controller on the AP three
okay that's complete
it'll an go in put the arm at the
position for the plume attachment
contamination experiment it kind of
gives some interesting video if you want
to look at that link yes we're looking
in the windows
great smiles
lots of big smiles up here story
sunglasses to kin story we thought you
only had KO video through the East
address we've got it the entire West
pass here I gym off
that's a Louisiana smile yes it is
Nigeria Ross
Lane is Houston
but you don't have the resolution y'all
do but I see there's a coming up on a
clear area over Canada right now I don't
have your exact location also great like
that is clear but I didn't want you to
miss it
that's great-looking country we're about
a minute to hand over to Tigre cease
okay story and what time are you going
to want to start the downlink of a glow
or the arvest camera and the recording
I'll kitchen keep your season okay
