I ask you what this suggests
this shot this scene for some
it could be the curiosity of one
baby girl for someone else could
instead, it is a link to the neglect of man
Well then let’s take a step back
let’s see what exactly happened
instant before a few seconds before
what we are
here is what we are seeing now is
a satellite in orbit a satellite stands
returning to the satellite atmosphere
out of control
ok he ‘s impacting those states
higher than the atmosphere disintegrates
once the speed is a bit
awesome is taking
practically fire becomes a ball of
fire what remains is actually
only a small part the part more
robust that made with i
more resistant materials
here this is what he actually was
looking at that child is rubbish yes
but it is a spatial diction that
technically we call space debri
but if what we have seen now is
just a rare event what’s on it
our head
what is above our head
perhaps for those who are not employed there
it can impress because in fact we
we are seeing a situation that is
unbelievable
we have to start a video
here it is what we are seeing is
a simulation carried out by the agency
European space is showing us
exactly what is perfect there is
showing exactly what happens
in around our land leaving
we are 23 from the greater distances
thousand kilometers
therefore below also that which
they are the most distant satellites then
geostationary if you see it is chaos
actually the amount of satellites
that we are observing is
impressive
we are approaching and the traffic is going
increasing
as you can see it is obviously one
simulation but that’s what happens
really because this is what’s there
above our head
if we actually consider that
traffic that is what happened since 1957
when the sputnik 1 was launched
is the first the first probe is currently
an estimate speaks that we have about 20,000
satelli we do not know the exact number
because obviously military satellites
particular satellites are not recorded
but 20,000 number that all in all can
look awesome in reality yes
drive well but we are in space there
all you want
ok, the space is big but it’s not like that
as big as we can think of because from
here the satellites will go to
to increase
and what happens when satellites do
they clash because of the 20,000 that we
we have talked we have censored
only a small part are operational
the others are reality out of control
here’s what we see here is right
what’s happening with the satellites
they collide and were debris
spatial
Well those little space debris that
we have seen at this time are
enormously more dangerous than the big ones
satellites out of control
this because because the satellites out
we can control
monitor them to manage them to control them
and possibly move the satellites
that on operatives that are in that one
orbit
but the small debris debris does not
we know we can only censor them and
although it is a debris it may have
small centimeters like ad
example a rubik’s cube
as in the orbit especially in the
low life moves at a speed of
almost 30,000 kilometers per hour
the energy produced is the impact
devastating a rubik’s cube and how they are
as 25 sticks of dynamite so one
small sphere of a centimeter of
diameter which is also equivalent to a bolt e
as if we were learning against a piano
100 kilometers per hour
here this makes us understand how much
fact space is not like that
actually it’s safe but why
we have all these these satellites in
orbit because there is all this traffic
traffic above our head
Well I’ll ask you a question who of you has
used a terrestrial technology a
public means to come up to here but
not many but those of you have one in your pocket
smartphone in with that smartphone today
he communicated he surfed the internet ha
consulted the weather forecast and maybe
went on google map maps for
possibly plan what is
you have your excursion tomorrow
rebounded that space constantly
continuously without realizing it is
one thing that is important is that if not
you realize
actually of what operated and
how much space technology used in
every moment
probably not yet you have no idea
of how much difficult space technology
why send something into orbit is
truly complex in our industry
it is said that space does not cooperate
this thing means to say
simply that when we must
make something this some
this car that we must
launch must be robust because it must
obviously it must be robust
not to break during the
solicitations of the launch but it must be
also light because it must be
launched into orbit
in practice it must be perfect because
because when in orbit
nobody is then able to repair them if
by chance something does not work
failed mission
here this is the main reason for
which the machines these satellites have
exorbitant costs but the thing is
actually changing because we are there
we are approaching that one
new was what is called the thick
economy expenses as what it means
it means that space is taking
more and more, even from the point
economic view for applications
also commercial here that then i
prices of these satellites tend to
to reduce to the dispositions eventually to
accept a small dose of risk
maybe making satellite instead of
have the twin as was often done
once it was solicited and
often destroyed to see what they were
the critical issues to then send into orbit
to the other and make it fly
now change now we are content with
some simulation is satisfied
possibly even some small ones
percentage for which satellite in orbit
possibly it may not work
this serves because this is why he asks for it
the space economy asks for this
faster times missions must
being faster is so I have to be more
bass this new often economy between
the other also concerns what is the
cost of launch because the satellite does not
it is only the cost itself to launch
satellites no of speech and satellite but
also launch it into orbit
we think that if it was a bit like dal
greengrocer when launching sabelli
the costs a little 3 kg
here are the costs as they are
practically coming down with the most
recent thick xd to masc when he has
launched falcon 9 hp
the cost has been reduced and a factor of 10 e
this means that it is an opportunity
for other business realities
approach the space because it often
economy among other things is approaching
completely different sectors
what in the future today will be a reality
tomorrow if now it often has economy sta
already thinking about extracting eventually
of materials a
make hotels in orbit this yes
science fiction is perhaps the future but if we
we think of the great visionary as
Richard Branson who has been for some time
working on space tourism
well this is actually because in 2020
on the rise in Italy just where it is
the Italian port effort for virgin
galactic and there you can unplug a
ticket of 250 thousand dollars that
it will be used to make a suborbital flight
over 100 km in altitude and for
privileged that they can afford
see what an astronaut feels but
space and also promotion we have
talked about the file with space hicks
here everyone will have seen the tesla
roadster in orbit is impressive
think what it would cost one
promotional campaign of this level
this tesla and will approach to Mars in the
2020 but the space however this expense
economy
excuse the word game from space
even small business realities
even small companies
one of these companies a company
Italian that I have the privilege not
I can say to drive but I can tell you
coordinate a company that has had
the opportunity precisely because it was accepted one
possibility years ago when a company
American that asked to realize
a telescope
we had all the competence to do
such a purpose has always been ours
work we did damage but a
telescope for space is completely
different we had absolutely no idea of
how to do it though was an opportunity that
we could not lose motivation
there was also the tenacity like that
we lacked the skills
here we have decided at that point of
dress up what a company for
a company the most important thing
human resources at that time there
we did a micro campaign of
return of brains fleeing in the sense
that we have taken of the astronomers of the
physicists of engineers who are
returned from abroad
who shared this challenge with us
of people who have left bodies
space agencies research institutions
much more structured reliable companies
of what could be a baby
Italian company but thanks to them in
this moment while we are
speaking
there are satellites that want to 450
kilometers of altitude with which the telescopes
who are doing their job and that
they are producing images
right now we are realizing
what will be the launch of dozens of
satellite telescopes for 2019 as well
for 2020
we are doing practically that
which is a small space factory but
this space factory will not arise in the
silicon valley will not arise
of the aerospace valley in california but
will rise two and a half hours here in the
veneto in this this beautiful
earthly thanks
