Why it Was Almost Impossible to Put a Computer in Space - NASA HPE Spacebourne 2

Thanks KIOXIA for sponsoring today’s video! Check out KIOXIA's SAS and NVMe SSDs below!

It’s really hard to put a computer into space… so hard in fact that laptops on the international space station are treated as effectively disposable. So when the folks at HPE wanted to put a SERVER on the ISS, people were a bit skeptical… and it turned out even with the help of KIOXIA’s fast and reliable storage devices, to be harder than they thought.

Correction at 15:20 - This is meant to say "TDRS Satellite" instead of "TRDS Satellitte."

It’s very hard to throw a computer that high and have it still work.

I like this sort of sponsorship; "Hey, we did a cool thing, let us pay you to come out and see it all and share how cool it is, to get our brand out there."

[evelynkieraivanova]

As an actual engineer who deals with SWAP and the difficulties of aerospace environments, I will say this video is well made and pretty accurate.

Many kerbals have died from "Computer bit flips"

I can't believe they built a fake sound stage to cover up the fact that Linus went to the space station.

So, in the once upon a time my grandfather worked for JPL, and I did in fact get to see a couple of the ISS modules at Cape Canaveral before they launched. And I can tell you... they basically looked like big white rectangles. Researching the tech behind them is honestly more fun.
But as far as computers surviving in space... my grandfather did work on two such computers that are still working today, more than 40 years after they launched... the Voyager probes.

11:41 One correction. The cooling loops exchange heat with the External Thermal Control System radiators (the two sets of 3 radiators closest to the modules along the truss)

The Photovoltaic Thermal Control System Radiators are the 4 radiators mounted between each pair of solar arrays. They only provide cooling to the electronics for their respective solar arrays. This makes sense because they are mounted outside of the 2 Solar Alpha Rotary Joints which spin the 4 port and starboard solar arrays 360 degrees every orbit. It’s hard to pass a fluid through a rotating joint.

Kudos to Linus for going to space without space suit just for the thumbnail

[sleipnir_]

it is ironic that "space age technology" needed to be older and more analog to survive.

[ramtinnazeryan]

that "Houtson we have a.. Linus" joke was

[aaardvaaark]

This video came at just the right time, I've been looking for a server for my space station.

[RomainCavallini]

OMG ! they put a "do not stir" label at 16:01, above the "o2 cryogenic tanks" label.
For those not as geeky as me, its a reference to the Apollo 13 lunar mission, that suffered an explosion due to a short circuit...while stirring the O2 tanks ! (Fortunately no one died, its a really cool story, there's also a movie about that)

[Luzgar]

The very idea of Linus Chaos Monkey Sebastian on the ISS is terrifying.

He would be able to make it drop from orbit.

[SanchoPanza-wgxf]

In 1998 a T1 (1.5Mbps) line on earth was considered impressive! Beaming the equivalent out to space was an incredible feat.

[VascoBreitenfeld]

Wow! This has got to be one of the coolest videos I’ve ever seen on YouTube! Great to know how the ISS operates and its constraints. It’s nothing like I expected! Please do more videos on space tech if you can 😊

[BlackHoleForge]

14:47 for anybody feeling nostalgic, remember AOL and dial-up. You would have to wait 20 minutes for a single song to download. Now you can relive the experience, all you have to do is become an astronaut.

[RandomToon]

They launched a hard drive with a super capacitor, but accidentally launched an experiment that tested what happens to unshielded super capacitors when bombarded with gamma radiation. The ISS will ALWAYS manage to gather data about something.

[redroyal]

Fun fact: the computers on board the Perseverance and Curiosity mars sister rovers are 30+ y/o designs chosen because they are radiation hardened, and if you think conputers on the ISS are hard, keep in mind that the farther out you go, the harder it gets

[DJAlexParker]

Actually found this alot more interesting than I thought I would, great video 😊
