ok
good afternoon everyone this is the
pre-launch news conference for crs 10 to
launch saturday morning to the
international space station aboard a
spacex falcon 9 rocket and here to give
us a status and talk about the upcoming
mission is dan hartman the deputy
manager for the international space
station program at the Johnson Space
Center jessica jensen the director for
the dragon mission management team at
SpaceX and Tara roughly associate
scientist for the international space
station program also from johnson space
center in houston will start first with
comments from our participants that will
take questions here in the audience then
we'll take questions on the phone and
then finally also questions on social
using social media simply by going to
hashtag ask NASA so we'll start with dan
hartman deputy manager for the ISS
program at JSC they have it good
afternoon it's great to be here as we
close in for the launch of the SpaceX
serious 10 mission tomorrow morning to
the International Space Station we've
loaded the dragon full of supplies both
inside and outside in the trunk
I think we're on the order of 5,500
pounds and and the most external cargo
mass that we've ever launched in the
trunk and so we're ready to go and
everything looks a very healthy for us
with launch tomorrow
Tomas will grapple dragging around nine
a.m. on monday that's eastern time and
then once he grapples the ground
controllers will will move maneuver
dragon onto the note to nader birthing
port and so that'll be done by by our
ground ground teams they are doing final
training on that over the weekend and so
they'll be ready to go when when dragon
does arrive our backup one state will be
on the under-19 and subsequently the
birthing would be delayed one day as
well
we'll get to work immediately onboard
crew be unloaded dragon and conducting
the research that we brought up on day
two is when we start all of our external
trunk operations and those run for about
15 16 straight days
this is the first mission where we were
bringing three pills up sage the sage
instrument plus his platform and then
the stp h5 payload know this will be the
first time we end up read returning for
disposal three payloads that have had
their useful life on board space station
so we re-interviewed those in the trunk
and bring those home and and that's a
great feature that we can keep cycling
out our research / over time as the
station continues on the mission
duration right now is playing for for 29
days and that would give a return on
march 21st if we look ahead a little bit
we do have some other traffic in around
the space station coming up the progress
6666 p will launch from baikonur on
februari 22nd that'll be a 34 orbit
rendezvous and docking on februari 24 so
you can see if we if we tend to slide a
little bit with the SpaceX mission due
to weather or other issues will have to
work with our Russian colleagues on when
we can drain bring dragon in also the
orbiter orbital 7 mission is is
progressing well its planned for launch
on march 19th understand sickness and
its service module were made it here in
the SS BF just this week so that that
missions looking great for us as well
and then i'll say post the OA seven
birthing operation which again was a on
march 19 and then until Shane returns
home on April tenth looking to conduct
up to three EPA's to knock out some task
that we've had our plate for a while
two of those would be associated with
some mDM's upgrade some Indians that we
have external that we're looking for
higher search for better performance we
also need to move the PMA 3 which we're
trying to do in get it situated on are
no to Zenith port which then we could
bring up our second Ida and have that
ready to go for are
Commercial Crew friends for a second
docking port and there's some other
tasks we changed that enduring these
EPA's we need to be ready to be
lubricating the dexter the spdm some of
its mechanisms over time they need a
little bit of of lube and then we have a
new power converter box that will be
bringing up and installing for our for
payload experiments so we've got a very
busy time between now and in April tenth
and everything / plan we think we can
make it all work with that our new crew
would shame coming home and 410 we are
new crew to the station would be
launched on 420 and then it'd be a a
typical riding pattern consumable wise
were in great shape
we've got well above our reserve levels
for food and water so we've really
dedicated this dragon mission to the
research and it's chock full and a
cruise really gonna enjoy the science
we're getting getting ready to bring up
we look forward to an awesome lunch
tomorrow and understand all of our late
low payloads are in there looking great
they're healthy they're powered on and
the isis is ready to receive dragon so
we're ready to go
alright thank you damn and now to
jessica jensen the director for dragon
mission management at SpaceX Jessica
storage
hello everyone so first I want to say
that we are proud and extremely honored
to be launching off the historic no
Apollo and shuttle launch pad at 39 a
this is going to become the primary pad
for all the dragon missions to the
international space station from SpaceX
we're going to be sending our next
generation of astronauts through the
Commercial Crew program off of this very
launchpad image that feels great on so
yeah we'll be sending them you know from
American soil on American rockets and
it's awesome it's very humbling to walk
out to the pad and see Falcon 9 standing
up next to this next to the 39th our
it's it's a sight to see
so it's been great i want to give a
special thanks to the SpaceX team that
has put a ton of hard work into
transforming this pad i'm going to make
a lot of infrastructure upgrades and
system upgrades to make this a
modern-day pad we want to do that while
also preserving its heritage and so
special thanks to SpaceX team that's
pulled all this together as for reading
this tomorrow damage and some of this we
had a successful Falcon 9 static fire on
Sunday Falcon and dragon are currently
at the pad like Dan mentioned all the
late low cargo is now in we load about a
thousand pounds of cargo all the time
critical science payloads get loaded 24
hours before launch
it's a unique capability the Dragon has
and all that should be wrapping up now
let's see uh think the last bit yes we
ran all of our final checks this week we
do have one issue that we're working
through we had a minor leak issue we are
still in the investigation for that so
it's a watch item for tonight but as of
now we are still on track for launch
tomorrow morning and with a backup
attempt on sunday so the way the mission
profile is going to work its standard
crs mission to the space station so what
is going to happen is the first stage is
going to burn for about two-and-a-half
minutes and then we get into stage
separation at that point the first stage
will break away and it flips around it
does the boost backburn
it will then perform an entry burn and a
landing burn to come all the way back to
Cape Canaveral and land landing zone one
the landing is estimated to be about
eight minutes after liftoff
now meanwhile all that's going on second
stage will still be carrying dragged
into the space station and the second
stage burn goes to about t plus nine
minutes at which point the second stage
engine is going to cut off and then
dragon gets deployed around T plus 10
minutes that point I'm dragon is
deployed and then we get in you were in
orbit and we start doing all our
on-orbit checkouts and activations
including deploying solar rays at about
11 minutes into flight and then at that
point I more set and we begin our to
date two day journey to the space
station C so I just want to thank the
FAA and the 45th Space Wing they've been
a huge help to us and getting this pad
going and ensuring that we meet all the
safety protocol and we're doing
everything we should which is great so
there-there support leading
to this launch in the support that
they're going to provide on launch day
has been great so thank you to the 45th
space wing and the FAA and i also want
to thank NASA mass has been our partner
for over 10 years and it's been
wonderful to work with you guys on cots
and crs missions so yeah thank you for
you know the continued opportunity for
us to supply the space station that's
about it for me we're super-excited for
lunch tomorrow
alright thank you jessica and now to
tell roughly the associate scientist for
the international space station program
are you so thanks everybody its I'm not
kidding when I say it's really exciting
to be here I've got to walk around a
little bit today on site and talk to
some of the scientists who are here
processing their payloads that are now
fully loaded on the vehicle and they are
amazing they bring the science to life
you may read about it you may hear about
it for me but talking to these
scientists their hearts are in it and
it's not just scientists that are here
but there are also students that are
here and it's good to see everything
abuzz over in the payload processing
facility and and everything that's going
on outside these doors so this is really
the golden age for space science
research it's a good time to be in the
program we're excited because we have a
laboratory that is at any given time
going to a performing about 300
investigations actually that's just in
the next six months and that's what this
SpaceX launch is going to enable in fact
is going to send research and hardware
to station that's going to represent the
work of about eight hundred scientists
around the world and that'll all be
performed by the six people on orbit and
those six people are the proxy
scientists in that laboratory where you
know microgravity is the one unique
resource up there that you just can't
replicate here on earth
so we're busy doing things there were
busy on the ground supporting what's
happening on orbit we are excited
because SpaceX also offers the
capability to research return our
samples to our researchers so anytime we
can get those back and get those in the
lab it's a researcher dream but i'll
tell you a little bit about some of the
investigations a very high level that's
that's being enabled by this particular
launched from the
national laboratory portfolio of
research there are a lot of commercial
payloads go around
they include growing crystals from
what's called monoclonal antibodies to
help fight diseases they include stem
cell research that could help battle
illnesses and diseases here on earth
wound healing from the DoD research will
be happening on orbit will see a company
called nano by osim that's going to
study bacterial behavior in space in
ways that could elucidate some of the
reasons for antibiotic resistance in
some of these superbugs we see here on
earth and we also have some student
experiments and space tangos tengo lab
system and also NanoRacks hardware
system and we even have commercial cube
SATs that will be sent up on this flight
that later be deployed from space
station so exciting newcomers to space
station research but as Dan mentioned we
have a big presence in the external
payload facility and the trunk of Dragon
that's going up a lot of hardware going
up a couple of those are earth
observation instruments and one in
particular is NASA's from the science
Mission Directorate that's called the
stage 3 investigation and its job is to
attach to the outside of space station
and look for ozone effects and aerosols
that affect the the ozone conditions of
Earth that's an exciting one because
those kind of stage experiments have
been ongoing actually since 1979 just
never before in the international space
station where they'll get a really
unique vantage point and a global more
of a global measurement capability so
that group is really excited
we also have another earth observation
platform from the DoD called the
Lightning imaging system and that's Liz
for for short and it's going to study
the pattern of behaviour of lightning
around the planet because it's going to
help us learn more about future weather
forecasting things like climate change
will learn more about atmospheric
chemistry and even be able to detect
aircraft safety you know these
scientists said this morning that you
get about 45 light
two strikes per second around the globe
and this particular team has a history
of studying lightning in the rain forest
areas now they'll get a chance to study
globally lighting effects too so so
we're looking forward to some of the
results that come from that the DoD I've
mentioned before they have a pool
they have plenty of Investigations thru
their space test program or sth five if
you look it up
they have almost 15 different
investigations and they're part of
what's going up in the trunk of the
Dragon and one of them is the lis
program
another one is called Raven which is
going to be a new system that's designed
to basically try to try to test new
navigation systems for autopilot when
you're trying to service something like
a satellite that wasn't meant for
servicing in space so trying to capture
satellites refuel then perhaps or or
prepare them and it's a brand new system
there's also a whole lot of physical
sciences going on and in particular we
have a suite of metal alloy processing
studies from our counterparts our
partners at the european space agency so
you know using the microgravity
environment to create solidification of
these alloys looking closely at the
changes that occur inside the materials
we are able to get those samples home
and perhaps look at new ways to make new
materials out of what they find
so you can see that this particular
SpaceX launch is going to keep our crew
busy it keeps us busy everyday i love
being involved in this because again if
you're if you're if you have any
interest at all in space science or
space technology or even if you're just
a curious human being
this is the time and we've never seen
such a platform like this enabled on
orbit for first science and so we're
making the most use of it both for human
exploration so we can go beyond
low-earth orbit but also to bring those
benefits back to us here on earth we
want to look at fighting disease
osteoporosis improve immunity and so so
it's really exciting to be here and do
that maximize the benefits that we get
from ISS that
Thank You Torah
and before we take questions a few words
about our weather forecast coming for
tomorrow morning
there is an upper level trough of low
pressure that's heading our direction
it's going to bring some increasing
cloudiness and some showers to the Cape
Canaveral the Senate e but most of
what's of concern is not going to be in
the area until after lunchtime so at
liftoff going to our first chart the
temperature will be near 70 degrees with
a relative humidity of 64% and the winds
from the South 1015 miles per hour with
the visibility of seven miles or greater
is a thirty percent chance of not
meeting the weather criteria because of
possible flight through a thick cloud
layer and should we postpone for 24
hours for any reason look at the
forecast for sunday and launch time i'll
just be some scattered clouds
temperature near 67 degrees northwest
winds 12 to 17 miles per hour and a
chance of an isolated rain shower there
will continue to be a thirty percent
chance of not meeting the law to whether
criteria on Sunday due to possible
flight through precipitation or
restricted clouds so overall a fairly
good forecast and no change from our
forecast this morning so we'll take
questions now please give your name and
affiliation when the microphone comes to
you and we'll start right here in the
front with Marsha Marsha and associated
press for Dan shane has got his mission
a little longer now and I'm wondering
how much more could you bump it if the
Soyuz problems continue to persist as
Peggy's homecoming still on track and
looking ahead are you looking to pick up
some more so you seats
ok so right now Peggy's on her and
normal plan to come home when she was
scheduled i will say we are having some
discussions with the Russians on you
know as an opportunity to maybe not
Peggy buddy I'd say us crew member to
come home on on the later so use as you
know the Russians will be flying to crew
on their next mission and so there might
be
an opportunity where we can do that
those discussions are just just starting
and so we do see that as a potential
opportunity to to really enhance the
research that to Tara was was talking
about as far as the Soyuz seats with-
you know that we have the option or the
discussion on going with Boeing and that
was a seat in fall of 17 a seat in think
believe it fall of 18 and then an option
if we wanted to exercise it for four
seats in nineteen three seats in
nineteen those discussions are still
ongoing nothing has been finalized yet I
think we're making ground but in again
part of the part of the rationale for
for going up to a crew of four and the
17th at least on the US side
well we know we're going to be there
eventually help us push our systems are
our ecosystem to see if there's anything
out there lessons learned why's that we
would that we would need to know ahead
of time as well as we can keep the 30
minutes basically doubling the
throughput on the research side and so
that is very very attractive to us and
so on both fronts we're looking we're
looking to hopefully be able to pull
those off as far as Shane's return I
don't know of any threats against 40
other for 20 launch date right now
obviously with the what will get the
progress off the ground will have a
whole lot of further discussions with
the with the Russians on on how well the
that's know those stages performed but
right now we we see four 20 as a as a
launch date sounds like you're French
astronaut maybe spending longer up there
is that what you're alluding to
uh-huh and how much longer would you
anticipate keeping someone up there if
necessary or wood wood could he be there
for a year I mean is that part of your
talks
I think there's again who do we have not
made any determinations said oh don't
have any agreement yet with the Russians
right so where is just work postulating
kind of thing I've seen the opportunity
there with that with that seat open i'll
say so whenever the 50s vehicle would
return would be would be when that next
one that if the deal was made whenever
turning crewmember would come home when
50s would return which is a launch on
420 bill harvey CBS 2 questions wind and
just to followup Marshalls question um
it is there any chance at all of its key
in pisgah come home just the two of them
come home in june and Peggy perhaps
stays up in space are you saying that's
not a possibility that is a sterilized
trying to articulate that's absolutely
that we were going to try to keep one
additional crew member up there that's
what we're in discussions with so that's
still a possibility at this point yes it
is
okay thanks and can jessica can you give
us a little more update on with the leak
but what the system is that's leaking
all we heard Pat was helium in the spin
system and I don't even know what that
is
so yes on the second stage it is the
helium system on the second stage is our
spin system that is partly used to spin
up the turbo pumps
however it is a redundant system and so
that's about all I can say right now
yeah we're into an investigation into it
we're checking it out and we'll know
more tonight same helium assistant
pressurizes the Tigers at a separate
different system entirely in other words
you know the tank that we had your
problem in September is a separate
system or is it from the same this is a
separate system yet there's a separate
system from the federal occurred
yeah I should also add that yet we have
redundancy and in the spin system in
particular that we have a our primary
mission which is obviously to deliver
dragon into its orbit after we do that
we like to dispose of the second stage
so what we want to do is be able to
relight the engine to dispose of the
second stage and you know get out of
orbit as soon as possible so that is the
the goal of this that's mostly what
we're looking into that that part of the
mission could be impacted by this
weekend we're just checking it out
further requirement now I it is a
requirement for certain contracts and
certain vehicles
I do not believe it is a requirement of
the crs contract but we choose to do it
so alright further questions
great thank you
hi stephen clark from spaceflight now I
have a question for jessica i think last
year it was we heard that SpaceX was
thinking about reusing a dragon cargo
vehicle for a serious mission and I
think SpaceX es 11 was the number that's
up coming up next
later this year the spring has that been
finalized by both NASA and SpaceX maybe
dank and China and since he's rolling
that too thanks to my internet well I
happy that ticket so our plan is that
again for for serious 11 it's going to
be the dragon is that so that the not
the Falcon not not a reused booster
exactly so that is we've done a lot of
work with with SpaceX over the last year
and a half her to look at delta
verification requirements that we need
to be comfortable to satisfy you satisfy
ourselves that dragon can approach the
ISS get within the lip sword be you know
be doing done safely and so a lot of
technical work is happening and i would
tell you everything is leaning good that
will be the next dragon mission that
will launch will be at reuse as far as
the booster we've just i'll say started
those discussions were we've got some
teams off generating how will even go
about requesting information from from
SpaceX kind of laying out our plan
I imagine we'll have some sort of
limiter review on that i'll say in the
April May time period but I think
planning why's it may not happen this
year but shortly thereafter
all right questions on the side of the
room right here Jim Siegel and with
celebration news and spaceflight insider
have a couple questions about the
payload medical-related payload that are
on this on this flight
you mentioned a couple of experiments
that have to do with
directly or indirectly osteoporosis and
antibiotics and wasn't interested if you
could elaborate a little bit more on
each one of those what how do those
experiments related to benefit that
we'll we'll see back here and on earth
and about how long is that going to be
five years ten years from now or what
such a good and loaded question i love
it so the thing about spaceflight is
that we see lots of different changes
from all the way from the soil level to
the human physiological system and so
this particular flight and this
particular set of research are focusing
on immunity stem cells and wound healing
and so the first one of regarding the
immunity is a his investigation of an
already fda-approved drug from merck
it's called key Truda and this is a drug
that works with the immune system to
basically fight disease such as cancer
some cancers what they want to do what
works using the microgravity environment
to do is to try to grow this type of
medicine up in a crystal form so that it
is more effective when given and in
injections format because right now that
drugs given intravenously
oh I'm so the researchers will get those
crystals home and look into those
crystals and see if there's any insight
that they can use that to help improve
their fda-approved drug already in use
the second is an investigation on stem
cell growth in space by the mayo clinic
they have a goal of trying to
mass-produce stem cells that can later
become any kind of cell in the body that
you desire and that could be very
powerful when treating diseases and so
they hypothesize that the microgravity
environment could help produce larger
faster numbers based on the
investigations they've seen in the
results in the past from use in space we
have done stem cell research in the past
and it looks like this could be
promising another is from the Department
of Defense that's the wound healing
investigation that will be looking at
the healing of wounds in our mouse
population that we're sending up on this
flight and that will be we've seen some
of the wound healing process is slow in
space and so I what that has to do with
no one's quite sure it could be immunity
it could be environment but so we're
gonna look into this a little bit more
and try to get some answers back on that
and these kinds of things I mean you
know the immune system is a big one all
these investigations and when we think
about things like osteoporosis then we
think about the fact that our
crewmembers on orbit if they didn't have
their exercise routines in place they
lose they can lose bone at a rate of one
to two percent per month which is more
than even a postmenopausal woman and in
we can use our crew members as models to
try to understand and accelerated way
what's happening with bone loss when you
don't use your bones and so we look at
that as parallels to osteoporosis since
you mentioned that one
you're welcome yes question in the back
here partly he speaks Lincoln Center
questions for SpaceX while landing on
landis timers is living in the bar CH
whenever we can land on land we would
like to land on land it makes it a lot
easier after we land the first stage on
land actually comes over to 39a for
processing it's just a much simpler and
less expensive operation than having to
send a drone ship out landed out there
and transport all the way back so
whenever possible we want to land on
land here
alright let's take a question from james
dean and then we'll go for social media
James thanks much James Dean florida
today I'm just wonder if you could just
recap as simply as possible what the
issue was in September what you've done
to get back to fly to correct that and
then Dan as well I just wonder if you
could comment on the separate
investigation that NASA did
and you know didn't learn anything
different or anything else helpful or
what you all kind of on the same page
thanks yes i'll start um yeah so on
September at pad 44 one of our
commercial spacecraft missions we were
fueling for a static fire and we had
explosion in the second stage tank that
then took out the rest of the vehicle
and the satellite so what we found that
to be was on a rupture in our helium
system and as we looked a lot closer
into it we did a you know when the first
things we do actually is form an
accident investigation team and on that
team we have NASA the FAA the Air Force
Air Force lots of our yeah tons of our
partners on that team as well as several
space experts and we form a fault tree
analysis to go through and look at every
possible thing that could have caused
this failure to happen and we're trying
to address every single one of those any
one of them that comes up credible we
have to address corrective actions
against it and so we have a list of very
long list of those very long as default
some of them on that not be incredible
and then anything that could have even
if it likely wasn't the actual cause we
still try and implement corrective
actions against that and so some of the
things we've done is change the way we
load helium into the rocket that's been
one of our main corrective actions as
well as going back and looking at our
processes to make sure that I feel like
this couldn't happen again
imaging we did we had an independent
team working right with the with the
with the SpaceX team was actually done
led by for LSP program here they did a
very similar exercise fault tree
analysis and then we look for you know
basic root causes as well and i will
tell you learning about a submerged in
very cold temperatures the Copp even our
NASA expertise right that's a little bit
out of SAR boundary conditions as well
so we're actually going to go in with
SpaceX go do a lot of testing and really
try to understand that for future use as
well how I copp in
in the conditions that they're they're
operating in perform always we think
they should perform you always get into
this test like you fly kind of thing and
so that that kind of philosophy got
brought across several systems and in
Jessica mention it there were there were
corrective actions that they found as
they apply the knowledge that they learn
from this investigation they applied
across other systems and their there are
some things that will probably that they
agree that we need to go work on as well
and so those are all be put into put
into motion to you again learn when you
can't see us and ghosts always says you
know some of these anomalies are
blessing that you that you get to learn
from them so we're trying to take
maximum advantage of that
ok let's do social media question here
sure i'm emily from NASA social media
and have two questions from Twitter the
first one is was Dragon Mountain mounted
during the static fire test earlier this
week if not is this a new pre precedence
for static fire tests so no was not
sunday we went out for static fire and
it was just the rocket by itself with a
cap on top for now that is the how we're
going to operate we are going to
continue to pour perform static fires
without a payload without dragon on top
but we do believe we can get back into
safe operations we do believe that the
way we're operating now is safe but just
out of an abundance of caution we are
not going to have payloads installed for
the near-term future during static fires
second question students created parts
that are on the payload as part of the
hunch program what are other ways that
students can participate in future
launches oh I love that so students
participate at in just about every
investigation that goes the ISS I mean
seriously whether they're undergrads
graduates are K through 12 there's
always some element of education but
there's also things like the Sally Ride
earthcam project where students can sign
up get on their computers pick a target
of interest that they're interested in
the space station taking a photo of the
earth and get those photos sent back to
them
there's also a project like the ISS ham
radio where students can get together in
their schools and communicate with the
space station with the astronauts on the
space station through hammary
do their our investigations through our
partnership or international partnership
sometimes it's is a like sending up
seeds like tomato seeds that are going
to be sent up on the spot flight by our
canadian space agency partners and you
get those home and students can grow
those up and and create a curriculum see
what comes out of that so there are all
kinds of different educational
components and also lots enabled through
the National Lab payload you know things
like that go inside of the NanoRacks in
the space tengo hardware where there is
fully data and there's imagery and these
some of these samples can get returned
as well I seeing things like fruit flies
for students who are studying and trying
to correlate to parkinson's disease or
this time we've got house a cactus
scrubs carbon dioxide out of out of the
air but there's an actual carbon dioxide
sensor with some cacti grown in there so
it's so these these students get really
creative and and and it's just becoming
more accessible for them to get their
investigations on station and it's great
because when your when your student or
your kid like me who loves space this
kind of opportunity would have been a
life changer
so it's really exciting that much
program is just really cool i mean these
these students across the nation right
working with their teachers and their
teachers work with some of our design
engineers and they are actually
designing building flying you know
things that we really use on the
International Space Station it could be
simple things are getting more complex
and then you know we get to go share you
know even with the crew members they
share the experiences of how their
hardware that they design and build
operated on orbit and so is just just
one of our are better programs we have
here at NASA honestly it's awesome
project using managers light up all the
time when they talk about hunts see that
yeah right
go hard with CBS follow
just agreement for Jessica again that is
gonna make sure I understand what you
said this was a redundant system so i
assume by that means if it is the it's
the second system didn't work at all
your second stage would like fine going
uphill and it would like find the orbit
or you saying that the issue is you can
like find going to peel or you might not
have the pressure to deorbit which wich
scenarios
it's the latter what you're saying but
you know with any negative energy you
have any issue on a rocket you really
want to ensure that just because you
think it's gonna affect the you know the
secondary goal you really want to make
sure it's not gonna affect the primary
mission and so we're still doing our due
diligence today to ensure that this will
you know it will have a low-risk mission
and that this will not impact the
primary mission so you know we're really
thinking it would expand affect the
disposal burn but we want to make sure
that it will not impact the second stage
burn tomorrow okay thanks and one more
and maybe this is for dinner or either
one of you I've never really understood
how you think the helium tank ruptured i
meanwhat physically caused it to rupture
what was the physics going on
it made the CEO pv burst that that's
what I'm not making a connection between
you get the high-pressure healing going
in an extremely cold environment you
have some buckles in the carbon fiber
over at but I don't understand the heat
source or what could lead to a situation
that would make that tank ruptured just
been arrested that so we've looked at
different kind of cars and I can't go
into too much detail about them but we
do we have found credible causes that
would cause an ignition event around
that area that's a ball that's about all
I can say I'm sorry I this is so oxygen
trapped
I'll say in some voids and then things
like friction can be an addition
alright so you can you know around
buckling sold that being that's their
scenarios that's one scenario and again
when you're part of this is the change
operating procedures of other actually
gonna go load so from work from our
comfort level where there where they
want to go we understand and so that's
why i think we can join forces with them
and looking at how we can do some
additional testing with these kind of
tanks at very low
submerse temperatures alright well we
have no questions on the phone and with
other questions here in the room just a
short programming note that are we have
another question where oh goodness all
right we won't stop
yeah so we got a little bit more time so
we'll take up yea Ken right here in the
front like Ken Kramer university know
theses trying to reform for Francesca
you're the dragon mission managers so
I'd like to ask you about reusing these
dragons that now you want to use on the
next mission
I'll tell us about the work you need to
do to enable that as well as Gwen shot
will mention that you're going to reuse
one of these just she just mentioned
this at to send to Mars so how you gonna
do that what are you going to select and
the other thing I'm wondering is about
the late load cargo thousand pounds is
about twenty percent and so how are you
able to do that
yeah so start with the the reuse dragons
the process is very it's twofold
so first of all you have to ensure that
every single component on Dragon all the
structures are qualified for multiple
flights and this is not a typical that's
what shuttle had to do aircraft have to
do that so you just have to ensure that
all your components are tested
thoroughly tested analyzed for all the
flight and ground cycles that it will
see so that's the first step and then
the second step is to have a thorough
refurbishment plan so we have to look at
each component look at areas you know
obviously dragon splashes down the water
to look at areas that could be
susceptible to corrosion and we have to
have very thorough inspection procedures
and in certain areas you know if
inspections gonna feel we have to make
sure we have hardware ready to replace
it so while this capsule is mostly used
capsule they're definitely components
that we looked at we said hey you know
it's actually going to be smarter to use
a new component in this area and we
provide all of the stated and NASA
literally on a component by component
basis and actually been great with their
experience on shuttle they've reviewed
every single one of our qualification
plans as well however as our
refurbishment plans for every single
component and it provided us feedback
that's been very helpful
I forget what was your second question
ah so it's actually gonna be the same
approach now instead of seeing the same
mission twice it's gonna have to see a
very different environment so but again
the same philosophy supply and the late
load cargo is a lot of practice so we've
actually been doing this since Sierra
serious one we had a little bit less
late low cargo we actually increase the
vehicle starting starting on cs3
starting on C rs3 we significantly
increase the capability of light load
cargo on Dragon and what we did is we
knew we could physically you know you
can run time studies to physically show
that you can get all the cargo in that
amount of time and then we practiced it
and so we practice it several times
before we actually had to do it because
you have one should start you know your
mission is coming up in 24 hours so you
better get it done but our teams have
now done it we got it down and yeah it's
not no problem we're pushing it right so
right the more we can get into late load
those scientists really appreciate
something being loaded it at the 24
hours and you know 36 hour time period
so we have constantly been requesting
how can we actually get more stuffed in
in that late load very late load access
point that's where you see are glaciers
are forming our freezers all kinds of
freezers going in with all those samples
we bring those out from the SPF and you
know we have fine-tuned this and it
working with with the Dragon focus on
how they actually do that and integrate
that in fact we both witnessed that out
there this morning when they were when
they were loaded in the glaciers and
they had the animals that are they at
animal habitats ready to go and so
they've done a remarkable job in and we
use it i mean our life sciences research
community really appreciates the amount
of research that we can get in the
timing that were able to load these
their samples in and then get those
return
it's been awesome question right behind
candid you
i'm sarah lewin from space.com my
question was partially answered just
then but i was curious to some examples
i imagine the mice and their habitats of
the time critical science payloads that
are made possible by this late load
question so from what I understand from
talking with the scientists this morning
who have been up all night that would
include the stem cells possibly the
protein crystals that are growing as
well there's going to be grown as well
and the bacteria that we are sending to
space station that have to be late load
last-minute critical and again those
those those teams have been up all night
as dance studies we watched them get
loaded this morning and those teams are
exhausted and excited
ok we'll take one final question Stephen
Clark I think you got a question in the
back
stephen clark spaceflight now again
hopefully a simple question for Jessica
which pressure shell will you be reusing
coming up on CBS 11
it's the cs4 vehicle
alright with that we'll we'll wrap up
just your programming for tomorrow we'll
start with the launch broadcast on nasa
television at eight thirty eastern time
and then after launch there will be a
post launch news conference here in this
room at 12 note thank you very much
