[Music]
well I'm sure you all are quite aware
that the race to space in the 50s and
60s in the last century was totally
military driven well not much has
changed here however um we have have
here the Liber the liberus Space
Foundation
and they are bringing back uh the hacker
mindset to the space
echosphere so there is mantos Papa Mao
Mao and alfredos
damalis and those two will now present a
lecture and how to hack your way to
space thank you thank you very
[Applause]
much so actually he spoiled uh half of
the presentation
yeah okay so I'm Manos and here is my
colleague Freddy and we are here to
present the lias pay Foundation how we
hacked our way to space and when I say
we I say we the hicker community and not
we together so
uh just uh as the X said the the old
space started uh with the Space Race
during the coldw era and uh started uh
fully under the uh tag of
Defense uh industry and defense
agencies and is uh full of um uh
classified stuff confidential export
regulation
Clos
technology um State Secrets
even uh technologies that are public and
data that are public uh in other sectors
like in in aviation like the the
position the awareness of the space
positional awareness uh in space
industry is something that is
confidential and uh imagine that the
first people went to space and the first
people went to Moon they fly uh on board
Intercontinental
ballistic missiles built to carry
Warheads nuclear warheads through
continents for a for a for a war and and
the people that they were building and
designing the spacecraft and the
spaceships there the same people that
building and designing uh war machines
so uh noways we said that we are in the
Space 4 era or new space era and uh the
people saying that uh the the space for
is the democratization of space and they
say that is
the uh the privatization of space and
that the the first private rocket went
to space which is not real because even
back in the day Saturn 5 the the the
rocket uh that used U that went people
to to moon is built by the private
Company by by boing and uh what they
said
democratization it means means that you
don't have to be a fighter jet pilot in
order to go to space but you have to be
a billionaire to go to space so for for
us this is not um the democratization of
space So yeah so
uh we are in
2023 and uh uh the space exploration is
entirely occupied by a space uh industry
hidden behind the closed uh uh
doors uh well not entirely there is a
village of uh hackers uh that
uh uh still uh holds out against uh this
uh this uh ecosystem this closed
ecosystem so uh one of the houses of
this uh Village is uh uh hikers space.
grr hikers space HR uh which is a hiker
space uh founded 13 uh years ago in uh
Athens Greece and uh one of our first uh
uh space projects was uh uh sadok uh uh
project which is a ground Station
Network with ground stations like this
one which is uh open source and open
Hardware uh uh
design uh and with uh components that
are 3D printed or components or parts
that someone can easily find and build
uh a station a station that can
join uh the sadu Network a global uh
crowdsource uh network of ground
stations uh that tracking uh and uh
communicate with satellites currently we
have uh more than 400 uh stations around
the world and uh we also have a database
uh about
uh which is uh also crowdsourced uh
attempt to gather uh information about
satellites their orbit their their
orbits and uh their uh frequencies uh
that they transmit to uh also so uh
someone in this database can uh upload
uh demodulated or decoded data for for
the satellites currently we have uh more
than uh 200 uh
million uh data and uh we get this data
and also visualize them in grafana dash
Sports uh and help satellite teams to uh
track their missions and find
information about their missions for
example here you can see the uh Bobcat
one uh Mission which is which was a cub
side and I said was because uh now it
has
re-entered so um uh one day uh while we
developing uh satos Network and SAT plan
hiking around the hikers space uh we got
a call from a University of patas
university in southern Greece and
actually they said what the slide said
uh we are building a satellite we are uh
six six month uh months before delivery
and we want help to build it so we have
no idea how to build a satellite but we
said we will build the first open source
satellite ever in space so we took the
challenge um we did a research on on on
the on the satellite and uh we found
found out that uh almost nothing was
ready uh except uh
um three students that are brave enough
to uh come with us and help us and and
and become uh part of this uh project
that called
ubat um and help us to build this uh
satellite so it was uh 6 months of a
constant uh emotional roller coaster
we're going from a super excitement to
learning to designing to failing to
desig again learn again excitement again
and then uh and then fail
again uh so uh we build a lot of stuff
we we we learn a lot of stuff and we
also buil the tools to build the
stuff uh this is a closeup picture of
the antenna release mechanism of ubat
satellite is something that uh in space
industry is called
Fancy uh thermal knife but it's just uh
is very common in space when you want to
do deployments uh the easiest way to do
it uh is um the simplest way and you
just spring load the device you want to
deploy you close it down and you held
the you held it closed by a a melt line
just a string that you pass through a
resistor and when you want to do the
deployment you just pass current through
the resistor the resistor is getting uh
heed melts the line and you have the
deployment so it's uh that simple not
not move moving not moving parts and uh
uh it works really really well but the
problem is that um when you're in space
you don't have atmosphere so uh the uh
the way um heat works in uh in Earth is
that uh you transfer heat mostly with
convection but in space you only
transfer heat with radiation and that
means that uh if you put the same
current here in Earth uh as in space you
probably will uh evaporate your resistor
you're going to heat up a lot more that
uh you do in in atmosphere and the
resistor will evaporate before the line
melts so we needed to build an
environment to simulate the the space uh
vacuum and um we came
up so this is our vacuum simulator it
also used uh for pressure simulator so
this is uh why it's so biffed up um it's
still like this we have tested uh like
hundreds of parts inside it and every
time we use we said uh we should paint
this uh F Tube bottle but never uh we
never done it uh it's just a gas bottle
cut in half with some uh uh really bad
welds on it and um uh pass through
cables and a window in to be able to see
inside and this uh uh inside this we did
the
first uh test and the last test of the
devices that we have sent this page this
is an an example of
a uh resistant an Nome resistor melting
a dma string I think this is uh yes and
now as you can see that that the wi is
glowing but it's not uh evaporates and
uh it's glowing inside vacuum is so the
whole thing is just an over engineered
uh low efficient light bulb so yes we
did the the first test and the and
actually we burned the first resistors
because we we size the resistor based on
the experience in Earth and we burn them
up inside so we need to to change the
sizing of the resistors to be able to
operate right in
space so another thing we built is that
um when you build a satellite you need
to build it in a clean environment and
the reason is that uh um there are a lot
of reasons uh the main reason is that
when you are in vacuum again uh the
evaporation temperature of uh all
materials is really really low so even
your the grease of your fingers on the
satellite will evaporate and and will be
cover anything like your Optics your
sensors your uh whatever so you need to
build it on a clean environment uh to
avoid uh covering your uh your Optics
with uh grease or the or the sensors and
Optics of other satellit that you share
the uh the right to space so we went out
to the market we searched for a clean
glove box and the options were super
expensive uh laboratory
equipment uh from Europe or uh um
devices like glove boxes from China that
the ETA like the estimate time of
arrival were was uh like 1 month after
the supposed launch of the of the
satellite so we built one this is built
by acrylic uh um acrylic seeds and is uh
has a hea filter and it's designed to to
go up to ISO 8 cleanness but it measured
lower than so even better than is8
cleanness and inside this glove box we
have built three satellites
that went to space two satellites that
almost went to space and uh and two
deployers of satellites so now we're
building a proper clean room and uh
we'll keep this uh just to
do uh hard drive uh swaps that we have
done some with no success yeah so
another thing that we try triy to do is
to follow the the software style of
development the Agile development with
uh Agile development of Hardware uh we
were doing uh what the software people
called continuous integration we're
building mockups using 3D printers we
building using lasers or you we were uh
uh printing out P piece really really
fast to do uh as much uh as uh to to do
testing continuous testing in order to
have a really quick release cycle and be
able to to test stuff quickly so those
are uh 3D printed mockup of the
satellite in order to measure the cables
and the left one is
um um the engineering the first
engineering model of the satellite have
having some of the preliminary sub
subsystem inside
it um so uh this is the last picture of
the satellite in the hacker space in
inside the glove box we have built on a
uh holding base we have built in hicker
space and it's the last flash of the
firmware to the satellite before packed
and uh sent to to space actually and
this is the first photo outside of the
International Space Station our
satellite is the is the left most and
this uh picture was was taken by the
astronaut on board ISS this uh
satellites launched from International
Space
station and uh the satellite uh deployed
and transmitted normally then failed but
[Laughter]
[Music]
yes
actually it actually transmitted for
some days and then became a zombie uh
satellite that we was waking up and
dying random uh random times in in in
the year and deorbited uh I think 16
months after the deployment so um we are
still uh continue developing stuff we
developing uh what we called Ground
support equipment or GSC for space this
is a Helm holds really difficult German
name Helm holds um coil cage and this
simulates on the center of this cage uh
we simulate the magnetic field you can
produce whatever Vector of magnetic
field you want want so you put the
attitude determination and control
system of a satellite in in the middle
and you simulate uh the magnetic field
that this subsystem sees in orbit to in
order to do simulations and um uh to
simulate the Maneuvers uh in
orbit um this also is something that we
are developing together uh with European
Space Agency is um a communication sub
communication subsystem for uh Cub sets
is called satos coms is a techy solution
to use uh paired with satos network that
Freddy talked uh about previously it has
an sand and UHF transceiver and also has
an fpga on
board uh this is under development now
uh is on version 0.3 and it's going to
fly probably uh in three missions uh in
in 20 uh 24 and four missions
2025 let's hope because space is uh
always has
surprises
so this is a a very ugly but operational
uh stencil printer that we have built in
order to do the development because we
print the pcbs outside but we do the
assembly and uh of the pcbs inh house uh
we have manual pick and place we use
this device to to apply the soer paste
and then you we put the the components
one by one uh by hand we want to buy a
pick and place automatic pick and place
sometime we'll do
it and uh this is the super fancy way to
have to do thermal cycling is a reptile
egg
incubator that
[Applause]
uh that is so sold in Amazon it uses
p elements to heat and cold the um the
reptile
legs and uh we modified it we we change
the controller to be able to control it
and uh simulate the temperature we want
and we also need to add one more p in
order to reach lower
temperatures uh to do thermal thermal
cycling for uh space components the
thermal cycling is um is a procedure
that you simulate the life cycle of a
space comp component in orbit and
because in orbit you may some component
in some orbit you have like half orbit
Sun half orbit dark um you going to to
simulate this temperature difference
between the dark and the light side so
you do you speed up this um procedure
and do it
um uh a lot of times to check uh to
qualify the design and also the
workmanship and how well is built
component so uh while we building the
egg incubator we got another call from a
friend this time and he said that uh he
has secured a launch uh a position on
the maiden flight of a rocket uh from a
private compan called Firefly and
um uh he wed us on board the deployer
but uh he has no deployer so he asked us
if we can build the employer and take
two positions so to also build two uh
small satellites so um those satellites
called um cubics uh no pocket cubes are
5x 5x 5 cm are like this big like um
Rubik's Cube we supposedly have one here
but we forgot to bring
it but we can come uh we we're in the C3
space uh assembly you can find us there
we have a mo up of uh pocket Cube and
also another device and a lot of
rotators and stuff like
that uh so again 6 months I don't know
why they they want to pressure us so
much again you have six months to build
the deployer and also the
satellites um plus we we needed to to
send the mass simulator like a mass Dam
Simulator the uh a device that has the m
Mass the center of mass and moment of
inertia of the actual deployer to test
it on on the
rocket
so we started building this is the the
cubic is uh uh the pocket we built and
we we designed and built this is a an
early not is not so early is um is the
blueprint how how the an exploded view
of the actual satellite
light uh as I told it's 5x 5x 5 cm we
have already some components lying
around because we developed uh
previously a communication board for
this kind of satellites and we also
started developing uh the deployer the
deployer is the device that you bolt on
the rocket you put the satellites inside
and then when the rocket send the signal
you open a door and release the
satellites in the
in empty in outer space in orbit so this
is
uh uh one of the first preliminary
analysis uh on static load of the
deployer because in order to launch
something this is done uh in fread using
uh uh calcu uh we only use open source
tools because we think that uh if you
want to publish something open source uh
the tools also need to be open source
because everyone will be able to access
it um so yeah in order to
to to send something to space uh you
need to prove that this is going to
sustain the loads from the launch and
this is the first thing you uh that you
do is
to uh do an a finite element analysis to
prove that what we are building is going
to suain
the uh the loads and afterwards you need
to qualify on a real vibration table you
Bol the device on vibration table you
shake it and you see if is uh if has
some modal frequencies close to the
model frequencies of uh the rocket and
if it's going to sustain the the loads
so we search uh vibration table grease
and the result was
that so we tried to find the solution
again and the the closest thing we we
will be able to find it was um a
laboratory in Spain that was charging uh
2 to
three uh, uh EUR per day
plus uh two people to go there and come
back and the accommodation and if you
fail you need to get back redesign and
go back
again so we said that we need to go
there to do the qualification But be
sure that we will pass the qualification
uh in the first time and we designed
something to vibrate the satellites so
this is a a very elaborate uh
design and this is
uh the the orange device is the hacker
space sander we had a we have a sander
to sand the the bottle that we never
painted so we use the sander to uh test
the satellites and this is um in action
vibrating one of the this is the the
first mass uh dummy uh engineering model
of one of the small Pico satellites here
is operating on the visce and here is on
slow
motion so this test was done
to uh to check if the string that holds
the antenna will be stay on on the
resistors that is um uh tied on and the
actually went really well and we passed
the
qualification
uh in the first time so I
think ah
okay this is the integration day after
the qualification we took the the
deployer had six satellites inside two
were our satellites and uh the rest four
were uh two spang's entities the friend
that secured the the place and also uh
the radio Amer space Association of
Spain the amsat Spain so this is the day
of the final integration we integrated
all the satellites inside the deployer
uh we packed the deployer and we shipped
it in uh Us in order to fly and then we
waited something like almost a year yeah
almost one year because the the rocket
wasn't
ready we were asking like to to do
everything in 6 months and the rocket
wasn't ready for one year and 6 months
yeah okay this is classic space classic
space yes and then we launched and then
this
happened like
[Laughter]
yay so
[Laughter]
[Applause]
boom so
so one one of the engines uh
misbehaved and during the phase called
Max Q uh which is the maximum
aerodynamic pressure on the rocket went
sideways the front part separated
completely and then the team uh pressed
the self- distract button and actually
the way the reason that we waited for
one year for the rocket to be ready was
the self-destruction
uh the the self-destruction device yeah
so again the call now from the launch
provider said can you rebuild everything
six
months and we said come on now we have
the recipe we know everything uh we can
do it it's easily uh the only thing that
we didn't count on uh was the the lack
of components in the market it was in
the middle of covid and uh middle of a
ship blocked the Su canal and and we
couldn't find anything in the market but
we made we made it again uh on this call
also they said by the way uh we found
your payload the only thing we found
from the explosion was your payload
lying on a bits in
[Laughter]
California so they they said that that
the payload is intact they that they and
they sent some pictures and there was a
huge part of the rocket like a carbon
fiber part of the rocket stuck inside
and some I don't know some aerodynamic
magic happened and this thing landed on
a suy beach California intact uh the
problem of the stuff we said in the
beginning is that we don't have uh the
right to publish those pictures because
it's uh technology
export
but [ __ ] is our
[Laughter]
[Applause]
friend so the scale is wrong but
everything else is
[Laughter]
right so they sent us the pictures and
they said uh we can ship the payload
back to you and this took one
year because of the export regulation
problems we uh they had problem to
export from us something we have sent to
them and we have to prove them that they
are not exporting uh State Secrets the
device we have sent to them an open
source device that we have sent to
them yes and uh they said that this was
quick because uh the device was open
source they said public they couldn't
understand what open source means so we
sent some pictures from the integration
said is okay is uh the design is public
okay and uh because we are allies so
took only one year
yeah and this is the damage the the only
damage the device took is
the the broken uh uh plastic cover of
the electronics of of the deployer and
one Brave capacitor that
[Music]
uh sacrificed his life to save the whole
deployer
so we open the deployer and everything
said were like in minan condition
intact we open the deployer we removed
the satellites we remov them from the
from the rails and put them on the side
and the deployers thought that they were
in space they deployed the antennas and
start like transmitting signals like I
don't know how this happened and I'm not
sure like the explosion became on 15 k
kilm high and this thing fell from 15 km
to the beach everything tucked so we
will keep one of them for
um uh um for um like emotional purposes
I don't know and we call the other one
Lazarus and set it back in space in the
[Laughter]
first
okay so rebuild everything um put it
back on the rocket H by the way uh one
of the teams couldn't able to uh to make
the one of the satellites because of the
lack of components and we and we added
the M dammy inside
the uh the
deployer and uh we didn't have enough
components to occupy this uh place we
didn't have solar panels so we just
added only two satellites we have the
opportunity to add four
uh by the way I can tell what the
satellites are doing so those satellites
cubics uh the experiment is uh really
quick uh we're using Sato Network to to
monitor satellites and from the doler
shift of the signal of the satellites we
can determine the orbit of the satellite
and we wanted to try some different
modulations and different uh uh signal
types in order to find uh which is the
best way to to do the Doppler shift
calculation so ship it put on the rocket
and then we got
that so this is the deployer in space
Now with uh Earth Earth on the
background uh sadly we don't have the
moment that the doors door opens and
release the satellite because the
connection with the rocket
lost but uh we're able
to verify that the satellites were
deployed uh those are the the signals
received from uh cubic 3 uh one of the
two satellites and the this is the the
whole mission period uh sadly there was
an error on uh orbit injection so uh
supposed to be on 300 km and um orbit
lifetime in this orbit is something like
3 weeks but uh went in 260 km and the
orbit lifetime in this orbit due to the
drug the heavy drug is 4 days three four
days something like this so we we only
had um 3 days to do experiments and do
stuff we did it but yeah we I think that
in the next time we will be better
yeah okay and um something else uh
during our uh travel and in in in in
this space in space sector and space
exploration we found out that uh down
down to the engines the people that are
building uh the actual uh spacecraft and
satellites and doing the actual work are
uh Are People of Our Kind are hackers
are Engineers are uh we will able to
found uh to found um picture like this
this is the official uh NASA workmanship
standard uh standard uh guidelines
showing how to do piggy back resistor uh
and Dead buug uh connections on a
spacecraft what is acceptable that is
acceptable to do to add one resistor on
top of the other to fix some issues
Lively on a spacecraft not lively but I
I mean like on a spacecraft that will go
to Moon I don't know
so and the most famous hack in space
history is Apollo 13 that people uh n
Engineers found a way for the astronauts
to fix the the oxygen generation system
and bring them safely back to Earth
using only available material uh on the
on the
spacecraft
so yeah so another uh group that is uh
there from the early uh days of uh space
uh race and space exploration is uh the
radio amateur uh which with their uh DIY
culture and their experience in radio
and
Engineering uh they managed to find
their way in Spa into space so we have
an example of the uh Columbia University
uh radio amate club which was the first
published uh uh the sputnik's uh uh
recording the SP sign signal uh
recording we also have uh here in the
photo the Oscar one which is the first
radio amateur satellite uh built by
radio amateurs and sent into space 2
years after uh
sping uh and uh we also have radio amors
in Space 2 uh here is uh uh Douglas
Willock and radio Amer and an astronaut
and uh uh he's contacting from ISS uh
other radio amateur on Earth also he has
uh contacted several schools through uh
the radio amateur in uh International
Space Station initiative uh also known
as
Aris also uh we have another group uh
which is uh called CAD it's a group of
uh uh visual ual
observers uh which with Optical
equipment uh track
satellites uh you may have seen uh in
the night sky ISS or
Starling uh Starling satellites uh in a
similar way they uh make observations of
uh satellites and uh they can uh
identify uh which satellites are and
also uh calculate with uh a very
accurate uh uh way uh the the orbit of
uh the
satellites uh by
uh by using the background Stars cross
correlating with the background
stars and another uh early try
to um to unify the the the how the
people uh look space was the outer space
treaty was a treaty signed during the
Cold War by the two sides of the Cold
War under United Nation and
yosa and uh is the first treaty that put
the word Mankind and space in the same
sentence and um inspired by that we uh
created the Liber space bank festo is
the is what we think uh uh for space
exploration we need to um uh the space
exploration needs
to um actually this thing that this
spacecraft that we are all on board we
call Earth and orbiting uh the sun we we
we know that has an end and uh uh that
one time in the future we need to build
the raft and get all inside and go and
find another home another spacecraft
orbiting another star
and this raft needs to be for everyone
not for the rich not for the white not
for the privilege not for the strong
so uh the only way to do this is if we
do the space exploration C
collaboratively without uh the profit
being the the reason to do it so this is
uh our Manifesto those are the
principles of our Manifesto and the ways
to to achieve that which are open source
open data open development and open
governance uh our Manifesto went in
orbit uh on board uh our cubic
satellites uh this was one of the boards
uh inside them and
also uh with a command the satellites
were able to transmit the manifesto uh
from orbit also there is a hidden secret
uh Easter egg inside the Transmissions
of the
satellites that uh is
uh uh yeah if you want to have some
special swag from Li Space
Foundation find it
out it will be active during the the
days of of the Congress so yeah go go
out and find it yeah yeah just to add
you can use the S network yeah no no no
you don't
know okay okay and uh
actually that's for from us uh as our
Moto says per mastra with uh freedom to
the Stars so thank
[Applause]
you space exploration with mantos Pap
Pap
Mato and Alfredo stalis thank you very
much we have now some time actually a
lot of time for
questions um if there are some line up
at the microphones I'll call you from
there there's some question from the
internet first do we have something yo
there is something please there is one
question from the internet and how do
you put the parts into the clean glove
box ah okay
[Laughter]
actually the clean glove box is uh is a
positive pressure room so you uh you
clean there and push it inside the glove
box so from every crack and every hole
the cleaner uh goes to the dirt outside
atmosphere so you can clean them well
and then put them inside this is the way
in the next interation we want to also
add a um like um um a space between the
atmosphere and the and the
Box thanks okay um microphone number one
please hi uh my name is yashu thank you
for the great presentation was pretty
amazing and I was I was hoping you could
maybe show a little bit more light on
how do you actually obtain a space
launch because you showed the technology
the supporting technology I saw the
first launch of your satellite was um
carried out out of international space
stations uh I was just wondering how
does the process look like did you have
to get any licenses do you have to pay
for the launch how does the process look
like yeah okay uh pretty quick uh quick
uh the first launch uh was uh paid by
the university easy and the second one
uh was free uh actually if you are
nonprofit and you uh willing to risk
there there are some uh uh some
opportunities uh in Maiden flights that
they are too risky to add to for someone
to pay to add the payload
and uh also some last minute calls
because there is a rocket launch and
they have some spare 2 kg if you want to
add something so if you have something
on the rack you can maybe find a way to
launch it uh for us actually is not
really difficult we have find the launch
opportunities we also have some uh
flight Oort flight of opportunity aboard
the miden flight of Aran 6 rocket and
the other ways to pay there are nowadays
uh uh space uh
uh launch Brokers that you go there and
say that I want to launch this payload
or if you go with the standards like
Cube sets and stuff like that it's
easier and about the license sorry uh
you need to have license from the state
that you are uh operating and also you
have to have a license for the frequency
that you to to communicate from it and
maybe a followup I was maybe under
impression you could use European Space
Agency like the Isa Academy so you did
not use that right it was paid by
University then yes yes yes yes but we
co cooperate with a univers that using
the spay fly your satellite program to
launch okay that's what I thought okay
thanks for clarifying thank you okay
thanks microphone number three please hi
great talk great talk by the way so you
said that you are developing the satn
coms um module I was wondering if you
already started looking into um
communication security for telemeter and
telecommand definitely yes yes so a
little followup um are you working with
ccsds and those prot okay yes we try to
stick to the protocols it is very
difficult for the small teams to do it
and mo most of the times they use really
weird and Hy ways to communicate I know
but we try to to follow the the
protocols and strip them down in order
to be able to operate in small devices
and because we don't build a satellite
that has 300 uh watt of power so we try
to to stick to the space protocols and
be yeah interconnected yeah thank you
very much thank you still plenty of time
for questions microphone number four
please um so first thanks uh for uh the
showing the cool way you test or with
this slow budget um and also um you
showed this vibration table you built
did you also verify and if so how that
these are the correct levels you have on
the rocket no we
didn't actually we verified on the table
and this is uh something like the paint
of the bottle every day every time we
use it we say we should uh put a
accelerometer on top and try to find the
levels but who
cares we'll do it one day we'll do it
thanks forward to that okay okay
microphone number one there is a q yeah
I assume uh there's a great difference
between theoretically building a
satellite and practically doing it and
assume a lot of this information is
secret so it's company secret or state
secret how did you GA gather all the
information you needed for building a
satellite that really
flies W nice question one is
requirements yes that uh sometimes you
you get driven from the requirements the
other one is Academia that sometimes you
can find papers from universi that have
already built something and you can find
on papers uh stuff and the other one is
failure which is the you fail and you
learn like the the first satellite um
failed after like 3 weeks because of a
system subsystem failure that it will it
will be easy to to find out if if we had
the experience or the knowledge from
other people experiences so yeah we
learned the hard way
and and this is why we go open source to
to build this knowledge for everyone
and yeah another thing we want to do is
a Wiki page that called how not to build
a satellite
[Laughter]
yeah thanks uh microphone number four
please uh hi what in your opinion is the
cheapest best way to go to space for
people that you think should be uh we
should
use it it depends but I think that the
cheapest way now is to go with the
pocket Cube if you are able
to uh to certif not to certified to find
the the license because a bit difficult
because they're really small and the
agencies that track the
satellites but uh for people like do you
have opinions on how for for humans yeah
okay uh kital I think they they have the
they are the only team that tries to do
that they try to build a crowdsourced uh
rocket to send uh people in suborbital
flights at start but I assume that they
they going to
go like on a proper orbit but yes yeah
someday or if you have if you're a
billionaire yeah you can pay a position
on uh blue
origin okay microphone number one please
yeah thank you first for for the great
talk
um I have a question regarding the uh
the manifesto you showed and uh about
the the the governance and the the
openness and so uh what is the what is
the way uh to join the LI Space
Foundation because last time I tried I
was told that you don't accept new
members currently ah no come on really I
think that
we uh we don't accept members this is
not a closed community you can join our
channels and we have people that join
the core team of Liber Space
Foundation um I don't know there is no
formal way to join I think that people
from the community from the Shad project
or from the other project that we run uh
just yeah being there and about the
governance another part is like the open
development on on the project like the
governance per project and also there is
the governance as organization yeah I
assume that you saying about the
organizational governance yes yeah so I
don't have a straight answer on that
yeah okay microphone number two is hi uh
like everyone said thanks a lot this was
a really interesting talk uh my question
is uh I assume like on the pocket cubes
it's not possible but is there any work
on on steering and attitude control for
cube
SATs and like is that that a possibility
or is it just basically a a lump of
metal and electronics and it just goes
whichever way it was initially deployed
no no there are ways to do attitud
determination even on pocket cubes uh on
pocket cubes mostly passive we use
magnet you use magnets uh to orient with
a Earth's magnetic field and for pocket
cubes you can use a lot of ways there
are Magneto torquers or active magnets
to steer and uh you can also use fly
wheels and stuff like that to attitude
determinate and there are also some
tries nowadays to do also Maneuvers with
really small uh uh Motors that using
cold gas or uh ion engine or stuff like
that
yeah okay and microphone number one uh
yes who
yeah so a challenge is developing the
hardware but what is about or what
challenge do you face when for the
software development part okay do you
want to speak or I can so the the thing
is that critical uh code yes the problem
is that you cannot press the reset so
again ccsds standards have uh are having
some uh guidelines how to build and also
we used a standard called JPL I think
that is produced by the the the jet uh
proportional Ator of NASA for critical
code and there are some levels of uh
criticality on the code so we try to use
this kind of and also testing hum
testing and uh code testing I'm not a
developer
so but yeah something like this but yeah
test test test
mostly okay uh do we have any questions
from the
internet no okay then micro phone number
four please hi so um question how do you
envision the collaboration between web
Tre and the centralized
Technologies with space exploration and
her
observation did you get a question oh
hold
on okay silent fire fire alert so
basically we're shut down for probably
10 to 15 seconds everything the whole PA
will come up again sorry for that it has
it has happened I don't know five to
seven times already
today same here same here you won't hear
me just wait a little bit then we got it
the stream is not effective so don't
start cursing
around I'll TR in here
no
phph takes longer than
usual
[Music]
hard the
boot still
TRS let's dry no
nothing just nothing damn it well let's
wait for another minute or so otherwise
we just react the questions directly to
the speakers over
here same basically the same without
audience and people being a able to
listen to it do you want to go
on without mic come on
okay how do you Vis the collaboration
between web tree and the centralized
Technologies with faith observation he
observation
like web 3 and collaboration between web
3 and uh Earth observation yeah yeah
okay uh I'm not sure if I have the
answer but uh I think that the ultimate
goal is to build a network of things
like when every node is agnostic what
the other node is so if it if it is a
space node or an earth node or something
like this is part of is a ground station
is a satellite is a server is uh
everything is the same and uh work
together as a mess network not a network
uh I don't know something like this
yeah okay could you guys understand it
or should we can we continue like this
or everywhere
or yes no maybe yes okay well then let's
have the non microphone
one my question was uh not so much for
the satellites but for your deployment
mechanism um have you seen microphone is
on again um have you seen any kind of uh
licensing effort or or trying to
replicate your designs in some other
hacker space for some other companies
because I mean there's a proven to be
working and proven to be sturdy solution
out there now so why not just reuse it
I don't know why I do not use that
actually I know that company built a
deployer that looks a lot like our
deployer but is not our deployer I don't
know why they didn't copy I think that
uh industry has an inertia for not
copying stuff or steing and not copying
so they tried to imitate the design but
they didn't did the same design that was
over there and open and I don't know but
but there hasn't been any effort to
contact you for for licensing or for
from some other hacker space to build
their own not for the deployer uh we
have a lot of contacts for the satellite
the first satellite we have a lot of
contacts thanks thank you okay
microphone number two please hi thank
you um I was wondering how is liability
distributed between different actors
like who is hard responsible something
breaks or I assume you have contracts
where it says in 6 months you have to do
this what if that doesn't happen
happen this is
[Music]
uh this is weird because you don't
actually no one has liability and if you
want to be secure you need to be insured
and the insurance are super super
expensive so we don't care we build
cheap stuff so we able to launch it
rebuild it and uh rebuild it again and
um for for big satellites there are huge
contracts with liabilities and
uh and insurance is like uh I'm sure
that this is a thing for a big satellit
but for small satellite there are
nowadays some compan that they can
insure you the first time we try to
insure
something uh they had no idea they
talked us about millions of they asked
the price of the satellite they said
that we said that it's something like
500 or 1,000 and they said you did
something wrong add some uh zeros and
come back
again so yes and also there is a
liability against the state if you
launch something that is not uh
certified or broadcasting in wrong
frequencies but again because this is
international law is not uh clear
because you need to have a state sue
another state that is not valid is
international law it's something that we
all hope to be real
Stu like that yeah okay all right now to
microphone number one again hello I just
want to wonder if uh some of your work
open source work is used by commercial
companies in the industry like I don't
know blue origin Space X actually we
don't
know because it would be interesting to
know if you get ahead and your work is
valued in that space yeah actually we
don't know uh we know that we have some
contacts from uh companies and State uh
actors that they are looking on it and
they examine it
and uh one of them is a military company
from another country a big
country and they study this because they
start to understand and now with the uh
thing with the with components uh the
lack of components they start
understanding the power of open source
and power of having something that is
really yours because they like us
Outsource all the a processor
Manufacturing in a third country and
they realize that they don't have any
foundaries in their country and they
don't own any technology in this kind of
area so I think that they now even the
so like uh heavy moving slow moving
Space Industries start to understand
that the
um the way that that open source
software like one probably maybe there
is uh this is the the way to go for
Hardware also so I think that there is a
movement towards the direction but I
don't have clear that this company used
our subsystem to build something I don't
have something like this okay thank you
all right uh last question again
microphone one yeah have one question
with respect to your Knowledge
Management so I mean you're now here
since um what was it 2014 I think and uh
you build some really interesting stuff
with respect to test equipment so how do
you transfer your knowledge you have
about the Tex equipment and um all that
stuff you have built up there to the
Next Generation I mean people come and
go uh you need to do engineering changes
from time to time so how do you manage
that internally to to get to the next
generation of
students documentation is the only
answer there is not not not other answer
than documentation and uh for first
satellite uh actually we didn't document
anything and this [ __ ] is is a hell but
uh the thing that we change on the next
satellites and the next build we are
doing is documentation we try to
document anything
everything uh well and try to make
guides and uh very nice visual guides
for uh even for manufacturing because
this is also knowledge how to
manufacture a board how to what glue are
you able to use to glue this uh two
parts together and and you put it also
on your open source websites yeah you
can access them on the gitlab
repositories okay
yeah okay thanks mantos and thank you
foros again for this really nice and
entertaining talk thank you and let's
say goodbye to you with a small big
Applause whoever is left thanks thank
[Applause]
[Music]
