I hint about the only person around it doesn't have TV coverage of the things
that man got the black up now you're gonna be getting a TV picture now
they'll yes we are getting a TV picture
one all
there we have been draggin in range of the space station
yeah
alright welcome everybody to the throne headquarters of space exploration
technologies were here to unbale dragon version 2 dragon version one is right
above your heads in fact this is the the first dragon spacecraft that came back
from orbit you can see that the scorch marks on the on the heat shield the
thrusters that are fired
it's the real real spacecraft and i'll tell you what i'll start off by telling
you a little bit about but dragon version one before showing your dragon
version too but when we first create a dragon version 1 we didn't really know
how to create a spacecraft we're never designed a spacecraft before so while
they were there are a lot of interesting technologies in version one it does have
a relatively conventional landing approach so it it it it throws out
parachute to land in the water off the coast of California after comes back
from the space station and it does have a life-support system but not one that
can last for a long time or carry a lot of people and so it's it's a it's a
great space craft and it was great prove a carpet kind proof-of-concept showed us
what we want to take to bring something back from orbit which is a very
difficult thing to do
usually when something comes in from orbit of last year
it burns up in a big fireball so but going from Dragon version one who want
to take a big step in technology really create something that was a step change
and in spacecraft technology and it's so important characteristics of that are
the ability to to land anywhere on land repulsively so that's one of the things
that dragon version 2 will be able to do so you'll be able to land anywhere on
earth with the accuracy of a helicopter which is which like something that a
spaceship should a modern space should be able to do and it will be capable of
carrying seven people seven astronauts for several days
it it has an improved version about pika heat shield and it's all around i think
of a really a big leap forward in technology really takes things to the
next level
so with that let's let's see the dragon version we're going to do a countdown
here all right driver to you
yeah
so let that we have an animation that shows you how dragon version to work so
let's roll that animation
yeah
so that is how 21st century spaceship should land at a few other things that i
want to talk about some of the hardware & Dragons some of the technologies and
we're gonna roll those out and so if a few things that i should mention that
you saw in the animation but we don't have time to show you today other that
there's the docking mechanism so the dragon version 2 is capable of
autonomously docking either Thomas you are to pilot talking with the space
station or you know with the International Space Station potentially
other things and without the without needing a the station arm so the current
version one makes use of the the canada on that's on the space station wagon
version 2 is capable of of docking autonomously without the use of the arm
that that's a significant upgrade as well
and although it wasn't shown in the video dragon version 2 still retains the
parachutes of Dragon version 1 so that what we'll do is is when it reaches a
particular altitude at just before four Atlantic a few miles before landing it
will test the engines verify that if all the engines are working it will then
proceed to a propulsive landing if there's any anomaly detected with the
engines or the propulsion system it will then deploy the parachutes to ensure a
safe landing
even in the event that the propulsion system is not working and even after
starting the propulsion system it can afford to lose up to two engines and
still land safely and then after the engines are started it deploys the
landing legs for a first off landing and it that so the reason that this is
really important apart from the convenience of the landing location is
that it enables rapid reusability of this of the spacecraft so you can just
reload propellant and fly again this is extremely important for revolutionising
access to space because as long as we continue to
a throwaway rockets and spacecraft we will never have truly to access to space
will always be incredibly expensive you can imagine a scenario where in aircraft
if aircraft were thrown away with each flight that nobody would be able to fly
or very few maybe a small number of government customers and and the same is
true of rockets and spacecraft so that's that's really why it's so important to
be able to land positively land on land and be able to then reload propellant
and take off again so i look at it . . some of that the technologies here this
is a a composite over after titanium sphere and this get this contains the
ultra high-pressure helium that pressurizes the propulsion tanks that
feed the super Draco engine this is the the Draco engine which is maneuvering
thruster and this is essentially the same as the one that's so very similar
to the one that's on Dragon version 1 and version when they're 18 of these
thrusters for maneuvering in space as well as controlling the reentry the BB
trajectory during reentry
where is it a bunch of these on version 2 as well from proportions that . the
biggest single change for dragon version 2 is the addition of be super Draco
engines so that this is really a super-powered version of the the Draco
engine where is the the Drakkar engine produces about a hundred pounds of
thrust each of these engines produce 16,000 pounds of thrust so it against
the super
and that they're in Paris so that if if one malfunctions that is peregrine can
take over and increase thrust to compensate for the one that's not firing
and each one is in a protective shell so if anything goes wrong it's contained
within that protective nacelle this is also get what will be the first of fully
printed engine so this is a it is printed in analysis I special
high-strength alloy and it'll be Alex of the first time that a rocket a printed
rocket engine seized flight and then this is the the propellant tank this a
whole series of these Spears are around the perimeter of Dragon v2 and these
these are also common over after titanium and debate they feed the
super-ego engines which are operating super jet engines are operating at a
Chamber of pressure of a thousand psi and fed from the east part of a series
of propellant tanks around the perimeter and then we also have version 3 of the
peak heat shield so the base heat shield is that is the third version of our heat
shield technology the first version obviously flew on that version 1
spacecraft of there and we're not about flights or version to version version 3
and with with each one were able to make the readability of the heat shield
better so it it lates less as it as it enters and Israel's get two more flights
so that's a thatthat's dragon version too although it'd be nice to go inside
but for that we will need a comically fast a set of stairs
yeah
so himself
so I'm sitting here in the city here in the policy and pull it down so that we
aim for something with the growing version 2 for the interfaces and for the
overall aesthetic of something that's very clean very simple and I so as the
pilot you were able to interact with that the screens overhead control the
spacecraft and then we've got all the critical functions that are needed in an
emergency situation as manual buttons
that's what you see in this area here
yeah
right but that's a lot easier answer 0g by the way so that there you have it
dragon version 2 capable of carrying up to seven astronauts repulsively landing
almost anywhere in the world and something that's designed has said to be
fully reusable so you can fly this multiple times allowing for potential
dramatic reduction in the cost of access to space
I heard about the only person around it doesn't have TV coverage of the face and
then they got the black up now you're gonna feel pretty picture is still yes
we are getting a TV picture now
one all
