Inside A Satellite Clean Room

- Welcome to Innovative Space Logistics, in the Netherlands: they invited me inside their clean room to see an actual CubeSat satellite that's going into space soon! (No, this isn't a sponsored video: I paid my own way there!) Go look at their site: isilaunch.com - and if you need to send something into space, get in touch with them!

The satellite model I'm holding is holding is the engineering model of FUNcube: funcube.org.uk
and the flight satellite that I definitely couldn't hold is Nayif-1, a cooperation between the Mohammed bin Rashid Space Centre and the American University of Sharjah: www.aus.edu/ mbrsc.ae/

I worked as a welder for a company that made clean rooms. As a welder I built the physical structures, so had nothing to do with the final cleaning of the room, but even so the standards of cleanliness (even at my level) were insane compared to other manufacturing jobs I've had.
In most types of welding there is a protective film called slag that forms over the still hot weld. As the metal cools and solidified this slag hardens and is then chipped away leaving the metal.
Normally a few whacks with a chipping hammer or a bit of scrubbing with a wire brush is all that is required, but not there. We were not allowed to leave even the smallest particle of slag on any weld anywhere. It was insane. The LITERALLY went over your work with a microscope.
Welder here: Slag only forms during flux shielded welding operations, so SMAW or FCAW. During MIG or TIG the shielding is done by inert gasses, so no flux required.
Seeing how Tom is so charismatic, able to get into places unavailable for most of us, and seemingly travels around using teleportation, I have concluded that he is the Doctor. Explains everything, really.
+KedraIrke I signed a non-disclosure agreement...

Shhh...you're not suppose to let the general public know. Now we have to prepare for a subsonic psyic mind wipe.
He spoke for 1 second and I knew we were in the Netherlands
+ikkentim
it took you that long?
+ikkentim Man, I hate our accent >.>
+jurgyy You don't have to, it's charming.
+foobar201 But for those of us in the Netherlands who do have a more "accurate" (?) English or American accent, it really is very grating.
I identify more with Tom than I do with the Dutch guy.
+MelficeSilesius But what's more important? Being able to speak a whole new language in their respective accents, or being able to actually converse with people from an other part of the world?
Maxima, our queen, still has an accent. But we understand her when she speaks Dutch. It doesn't mean that I like the Dutch accent when speaking English, and thankfully I don't suffer from it. But I respect the people that at least try to speak an other language to the best of their capabilities.
Tom: I got an e-mail that said, "Do you want to come see our satellite clean room?"
Everybody Else: Only you, Tom. Only you would get a random yet once-in-a-lifetime offer like that.
Tune in next week for episode: "Aboard the ISS and the bug that almost killed Sputnik"
Fun fact the mission before sputnick which was supposed to be the orbital one failed due to a bug
Oh, hello Banderi! Funny thing coming across your Account over here!
Let this brief but friendly intended hello be offered to you.
Maybe I'm super ignorant but I always assumed satellites were much bigger. The fact that there are small satellites blew my mind! :)
+pingu5746 CubeSats are amazing things! Loads of them, all deployed at once, piggybacking on a big commercial launch. (And mostly burning up at the end of their life, to avoid too much space junk being created.)
@@TomScottGo hi
@@minhaz5704 What did it say?
Dustin from Smarter Everyday would love the laminar flow of the room.
Hehe that’s what I immediately thought

And Derek from Veritasium would dislike it
Haha, the accent "that's Dutch-English" guilty as charged ;-)
+Joop Terwijn Check! Guilty indeed.

I worked at a semiconductor manufacturer with a clean room. (I was in IT so I only went in once during my orientation). I don't know what the ISO rating was, but it must have been much more stringent. The air pumps would have been too loud to film a monologue inside it, and we wore surgical masks and goggles.I could relate to not knowing where to begin on getting into the "bunny suit". The wafers themselves were sealed inside extra-clean boxes inside the clean room, which were handled almost exclusively by robots and only got opened inside the machines working on them.
In all, I felt like I"d gotten a job on the Death Star.
I hope you get the chance to record a room like that, but given the trade secrecy of semiconductor manufacture, I wouldn't bet on it.
Linus tech tips managed to film inside one of intel's facilities, which is definitely worth a watch
@@conkerconk3 and one of micron’s (crucial) facilities
That Dutch English accent tho
+kupertjerobin As soon as he started talking, I was just waiting for confirmation that he's Dutch. Then I went to the comments to see what people said about it.
+kupertjerobin So as a Dutchman i cringe when i hear it i know i do it myself but what I always wondered how do native English speakers hear this? do they find it annoying or amusing? or do they actually like it? For instance I like French-English
(Your mother was a hamster and your fader smelled of elderberries i will fart in your general direction)
***** I checked out that guy's RUclips channel, where I found a playlist of Dutch videos. My guess is he is also Dutch, as am I. So we don't actually know if native English people do identify this typically Dutch accent.
+kupertjerobin verrie verrie dutsj
h well still the question stands, what do they think of it?
Don't be afraid to make these videos 4 times as long in the future! There has got to be a lot of neat stuff that you're leaving out, editing away.
Tom, I understand you think a lot about the terseness of your videos, but sometimes ya gotta make a longer video! Delve deeper into the legalese of the "customs box" or the diffferent ISO levels!
+Jacksirrom Please
perhaps do it like how Brady does his Numberphile/computerphile/etc videos. make the normal short video public and then have the extension of that video unlisted but linked to in the description. the longer video doesn't have new information, just more detail
I watch like 10 to 20 of your videos a day. One day I will have exhausted your library, and the world will never be the same.
I helped a concept design for a clean room to be used in cubesat assembly. Youd be surprised all the engineering that goes into a clean room. Very difficult to get below iso 6 and 5. Very cool stuff.
The fact that people working in clean rooms never seem to wear the kinds of full-face shield suits like in the film Small Soldiers never ceases to amaze me. Like, what about all of your eyelashes and eyebrow hairs? And yes, Tom, your (and everyone else's) saliva!
Fully recommended Small Soldiers to those who've never watched it, btw - not necessarily for scientific accuracy, but because of its literary themes of family, cooperation, and - above all - learning :-)
I've worked in a clean room like that and can tell you it sure as hell is no fun at all! Sure you get to contribute to great technology, but depending on which room you want to enter, you'll have to get through half an hour of just dressing and cleaning yourself up - and same again to exit. This is one of those jobs that are cool to watch and admire, but only from a distant seat of the internet.
Hats off for all those people working there every day.
Yup, so true. We always try to minimise clean room time, as it is very taxing on you. The worst thing is that the clean room coats and gloves make you sweat, but the room humidity is low. So you get de-hydrated easily as well.
And the constant aircon buzz is also not something you want to hear every day.
Fortunately, in our case, we work on project basis, so there are different people working on different satellites. So you do not get months of clean room time at once.
Tom, your videos are amazing. Thank you so much!
Awesome, thanks Tom and Wouter!
I absolutely love these, hope more people invite you to more places Tom!
I love how this video is about such amazing stuff and 90% of the comments are about the accent.
+ard k Well, I don't care. I'm Dutch and not afraid to admit my accent ;)
it gets better over the days when I'm in the UK by the way ;)
+Wouter Weggelaar How about your spanish? :) greetings from Chile!
My Spanish is probably worse than your dutch! ;)
I don't even speak dutch! XD
incredibly enlightening channel. very grateful for the time and energy you have put into making these videos. through your channel, I've seen places and learned things i otherwise would have never known the existence of. keep doing what you do. it benefits a great many.
I love anything about space! Thanks! This was great to watch! =)
Fascinating, as always.
clean rooms have been my second favorite type of place since I learned they exist. happy to see another!
Your videos are perfect for my ADHD. They're pretty varied in topic, simple, fascinating, and not too long.
Great Scott! That is a cool place.
I always enjoy watching your videos great work as always.
best place to put on a goddamn screen protector without a wild strand of dust popping outta nowhere
So presumably ISO-1 is the level where you break out the full isolation suits and stuff.
great video! I have always wanted to go in one of these!
Great video!
you are my favourite youtuber tom scott
I took a class on circuit fabrication at the University of Notre Dame. Their cleanroom's main areas are ISO 7 and ISO 6, with one small area that is ISO 5.
Really cool and interesting. Thanks.
2:10 well apparently they failed, as you can actually see dust on the satellite :P
+ybra I don't think that is dust, probably small scratches on the panels.
Switzer that sounds like it would be worse
+ybra It is indeed dust. Clean rooms like these are not 100% dust free. The risk of cleaning again and again is higher than leaving it until just before launch. The solar panels will be cleaned. A scratch would be worse indeed.
You sure it's not just dust on your computer screen?
+Wouter Weggelaar solar panels are hard to wash..we are making one of these cubesats and we haven't assembled solar panels yet.
that's pretty awesome. thanks for sharing.
You have the BEST job ever :)
That was a pretty *clean* interview.
My university in a Tom Scott video. Finally!
Amazing!
Of all the youtube people I would like to meet, you are on my top list. And now you where so close! Ever thought about a fan meeting?
Great intro!
What did you have to do to make the camera acceptable in that ISO7 space?
+Factoid We have cleaned everything using non-woven cloth soaked in alcohol. Taking stuff into the clean room is also a nice way to get your stuff cleaned;) The most difficult part is actually the little foam windshield on the microphone!
Wouter Weggelaar Thank you for the explanation.
i knew this was dutch from their accent, awesome!
Never thought that was actually exciting. :D
Someone needs to make a "Every time Tom Scott gets an email" compilation
hey thats my old classmate from TUDelft :)

Hey Jason. We have not changed it, its just the launch branch called Innovative Space Logistics (ISL). How are you doing? Your face is somewhere on our wall I think ;)
+Wouter Weggelaar ahh thats where my face is, I was searching for it :)
currently I work at Qutech, it's located in the physics department. if you want tour of our "Quantum lab" let me know :)
AWESOME!!!
ISL, you're awesome.
I should really check my email more often
Extremely jealous. Thanks for sharing the adventure though!
Cool stuff as always Tom. We have a clean room at my university that goes down to ISO 4 I think.
Just to let you guys know, incase you wondering, the yellow cable that attached to the technician hand is a static discharge cable that neutralize static change on your body when touching the electronics, so it doesn't damage the sensitive electronic circuit. It also used in many sensitive electronic manufacturer.
Great opening line :)
Just for clarification, that model tom picks up is indeed full scale, those satellites are actually that small. That's the reason it has dust on it, they don't bother keeping it very clean sense its not actually meant to be functioning.
@2.30 is that dust on that cubesat?
+Stephen Jenkins There'll always be occasional, small bits, particularly visible on solar panels like that: easily removed before it's packaged up for launch. Just imagine what it'd look like if you left it on a shelf outside...!
+Stephen Jenkins Yes, that is dust. The risk of removing that now, and then cleaning again and again, is higher than leaving it until just before launch. But yes, it is contamination. Clean rooms like these are not 100% dust free. What Tom said ;)
I visited MC2 @Chalmers once for a tour
ISO4/5 and room vibration of maximum of 3µm/s!! (room is inside a building, but is having it's own support). You should check it out. Does 8nm electron beam litography and quantum stuff as far as i remember.
Tom, you have the most amazing life. I don't know that I'd trade with you (for many reasons, even if it were possible), but you have such a wonderful opportunity to go, see, experience, and learn. That, and you don't have paparazzi endangering your life while you do it (I don't either, but that would be an instant reason not to do it). Add education to that mix and wow... you're cool. 😀
I am fairly certain that room is not laminar airflow. Laminar airflow would require the ceiling have 100 percent hepa filter coverage. They could even have a hood in there they work under, but the room itself does not have laminar airflow. It does push air from top to bottom but that alone does not make it laminar airflow.
Gezellig
recognized the accent the moment he started speaking, gotta love it ^^
Please Tom, I'm begging you, in the upcoming year of 2022, give us a video explaining customs cages. I must know why they are in place, and how exactly they work. The most baffling part of this whole video for me.
tom! your videos are too short :( but i love what you do. thanks :)
You're visiting the Netherlands so many times for these videos, Tom, you might as well come and live here...
For goodness sake..,.they already conquered the sea, and now they’re going after space!
These folks are ruthless!
1:55 this has to be the most Dutch pronunciation of Velcro in existence, god damn.
Is the satellite at 2:30 the model? I wonder about the clearly visible dust...
I think so i mean its pretty small. Maybe i didnt really catch that but if its a standalone satellite it should be bigger i guess
+Der Retro They are working with CubeSats, which are about 10x10x11.35 cm big (regarding wikipedia) so it could be the real one. It is also clearly connected to the ESD. I also wonder even if it is the model, it has the dust on it and it is IN the clean room right? Must have to be related with the fact it is "only" a ISO 7 clean room?
+Der Retro No cube sats are very small. These micro satellites are made to be small to make them cheaper to send up in space. The recent decades of miniaturization makes this possible. Though big satellites are still launched as some systems can not get much smaller (like if you make Hubble smaller you would also the optics poorer. Size matters when it comes to optics.) And some of those big satellites and probes are just loaded with more stuff.
As for the dust particles on it. I expect they will clean it before sending it off. Think of how much dust it would have on it if it was not in a clean room.
+Der Retro The cubesats are actually that size! They launch several of them on a single rocket.
Well thats stupid... How do you accurately keep track of the exact location, so no other spacecraft flies into them? I mean imagine having a mission to moon and one of those cubesats smashes the "windshield"...
the necessity of keeping clean the places we visit never occurred to me
Fun tidbit +Tom Scott
Intel's Fab 32 is Class 10 or ISO 4. No clue if it's still just ISO 4 since the info is almost 10 years old and it was for manufacturing 45nm stuff.
But I could imagine that the "newer" or upgraded fabs are ISO 3. Since nowadays we're down to 14nm stuff and 10nm is coming.
So, my bedroom is somewhere around ISO 11, I think.
You should do an episode where you talk about the size of satellites I was surprised by how small those were. All I have seen of satellites is from movies like under siege 2 and such
Yay Netherlands!
booty up, tom!
(the dressing room for a clean room is called a booty room in some places over here)
had the opportunity to look in on the clean room where they were assembling MSL a number of years ago when I was working at JPL. always awesome to see flight hardware
Looks like a standerd strong hold room !
i used to work in a medical manufacturing clean room. this video gave me flashbacks of the air and smell.
If the place is in the Netherlands, how can the Cube Sats not be in the Netherlands...?
Physically, thats the country they are in
+Trek001 I assume it's sort of like Transit zones at airports that aren't actually part of any country.
So it would be surrounded by the Netherlands, but not in the Netherlands itself.
+Trek001 its more of a tax technical thing.
I thought I heard him say, they exported from the Netherlands for the ordering country towards space. And space.... is not on the export form ;-) so the cube is build in NL en exported to space. (I think....)
+Trek001 it works the same as when you're on a plane and land in a country, until you pass through customs you are technically not in the country
+Trek001 Yep, it's a difficult one to explain! Search for "customs bonding" to help explain it. But basically: if you have something arriving from one country, then being sent on to another (or to space!), you can avoid massive import and export taxes by formally declaring an area as "not counting" for import, and making sure anything is customs-bonded on its way in and out. It's common all over the world for goods in transit... they're just not usually in transit to space!
Would you like a shmoke and a pancake?
mad respect for that Dutch scientist to (mostly) hide his accent, i barely noticed it
source: dutch speaking native
Oh! Fancy!
I knew this was in the Netherlands as soon as the guy started talking :)
hey this guy sounds like a fellow Dutchie!
Hallo!
Really interesting Tom. I wonder where operating theatres fit on the ISO scale?
As a guy with hygiene OCD tendencies, I learnt that nothing is ever clean enough, so I gave up on OCD, mostly. But it seems like I would be a good employee at a clean room.
Not the best person at math, but if i understand this logritmic scale thing, since iso 9 is dust in air, iso 8 is 10% as much dust as in air, and iso 7 is 1% as much dust as in air, than I can work backwards to iso 1 being 0.000001% as much dust as in air outside, now that is clean!!!
They have these at Texas Instruments south building in Irving and they're pretty cool.
The moment he started talking I knew he was Dutch :')
I love the name of that small communication satellite, Naive 1
TUDelft Aerospace! Represent. :D
I can imagine it now:
Sir! Our satellite stopped working!
Darn it tom! I knew we shouldn't have invited you to our clean room!
I still remember when I glanced over the TV and saw that guy on the news about a satellite launch or something.
And I immediately remembered this video.
I didn't even know about cube sats until last week. Odd to see stuff about it in my feed now
Forgive my layman ness but the places where the make motherboards and the such, what ISO grade are they?
+GabrielKnightz Motherboards themselves use packaged components. They are usually made in ISO 8 conditions. The chips on the motherboard are manufactured in ISO 6 or lower. CPUs are handled in ISO 5, except when in the machines, were it is even cleaner.
+Wouter Weggelaar
Thanks :)
What about hard drives?
Magnetic hard disks don't work well under low-pressure conditions like space. The main storage used in satellites are usually flash disks, which are chips designed to store data, however some older satellites are using magnetic storage (which is different from the regular computers disks, one of the differences is that they don't move to read or write data).
I think he was asking about the ISO grade where hard drives are manufactured.
Shutsh a kul ashtent. I 😍 it.
X 💓
awsum
I genuinely cannot wait for companies like SpaceX to bring the cost down enough to make ultra clean rooms like this almost obsolete
My father works in a ISO 4 cleanroom if I remember correctly, also in the netherlands!
1:40 he's explaining the hygiene required and the guy behind him isn't wearing a mask🤣🤣
0:16 Boxception! 😋
Show me an ISO 1 clean room.
Such a clean room that there is even dust on the satellite..... 2:11
