This is how ESA stores Earth observation data

[@JeffBilkins]

They didn't show much of them but those robotic tape changers are kinda cool.

[@DisusEye]

The shot of the laboratory looked so futuristic. Thank you for sharing ESA❤

[@joependleton6293]

The archive of ESA, safely stored and of further interest 😊

[@Thisandthat8908]

really cool. But a bit less preachy PR speech and a bit more information, technical and behind the scenes stuff would make it way more interesting. You know a bit more of what the title says.

[@virginiatyree6705]

Oh boy DISCO!!! Glad they're doing the work to help humanity. Thanks for posting.

[@photoo848]

Love that solution for the cracked media. It's the kind of ingenuity you only get to enjoy in amazing fields

[@JulienItard]

Very interesting, thanks for sharing !

[@johannesschielein7844]

Love the pizza oven solution! Keep up the great work and also the cool yt channel! Hope more people discover it still!

[@ZedaZ80]

Very cool, thanks!

[@RussTillling]

Great, love the friendly, informal presentation style 🤩🤩

[@_MP_TV]

Impressive

[@basti4954]

Thanks for storing all the data and providing it without paywalls for our daily work!

[@joeb2151]

Ok, those ESA cabinet temperature displays are cool. I have the APC cabinets, I need to know where to get those displays though, that's sharp.

Awesome video. Thanks for sharing!

[@V_AAM]

nice share and history ....

[@mariadaluzmoutinho5701]

Uma relíquia ...O avanço da tecnologia e o que pensarão os cientistas das transformações dramáticas da Terra?! Qual foi o melhor e o pior ano... nas observações nestes 34 anos?!

[@labber]

the oven thing is amazing. pizza saved us. thanks italy

bello fresco

the microsoft project silica with robots move to store data to glass is interesting for long time storage

[@ptonpc]

Good to hear the data is being safely stored. I presume as tech changes, the data stored currently will be moved to new media and everything is backed up?

[@EuropeanSpaceAgency]

Everything is properly backed-up and data are migrated to new technologies every 5-6 years. Now using LTO-9 tapes with next migration planned in a few years. Back-up is usually kept on a different technology.

Do they also archive the raw data from the satellites in case their is an error in the processing pipeline?

[@Dakta96]

The raw data is generally stored at the station in the form of CLTU. You also have some packetised data stored in various digital packet archives depending on the missions (some very old ones are not packetised but it's the same principle), backups included. What you see in the video is both a backup and long term storage for all of that data. I hope it's clear enough, I probably forgot a few things.

[@_yonas]

@@Dakta96 Cheers. - I'm curious about the level of processing that's done on the data before it is stored. I assume the satellites do some online processing of the sensor values, but do they also send raw sensor values before any calibration, smoothing, or other filters are applied back to Earth for storage? As an undergraduate and graduate student, I did some research (not related to space or earth science) and always made sure to keep all the raw sensor data in case I later discovered an error in one of the processing steps. The challenge with that approach was the sheer amount of data I had to store (only ~20TB, but that was still a lot too handle for me at the time). I assume ESA faces a similar dilemma, i.e., store all the raw sensor data and derivative data products, or be absolutely certain that the algorithms which process the data are 100% correct and delete the raw data after processing. Long story short: do you happen to know how "raw" basically the data is that ESA stores?

[@EuropeanSpaceAgency]

We archive Raw and Level-0 data to make sure we can restart from the beginning in case of errors in the processing pipeline but also to be able to improve the processing pipeline and reprocess new datasets with better quality and aligned to newer missions. Heritage data are continuously improved and need to start this process from Raw/Level-0 every time.

[@apollo209]

Thanks for showing us this and how important it is to keep records. I am curious though, how and where the back-ups are facilitated?

[@dissaid]

It's like a baby book, but with underground bunkers!

[@bronco_fv]

How much data is stored? Exabytes?

[@jonssonchrister2418]

☺❤

[@boeingpameesha9550]

My sincere thanks for sharing it.

[@gysghost5126]

In italy data is stored in Pizza

[@ca24tamie30]

In Japan the data is stored in sushi😂

[@ca24tamie30]

The ocean covers 71 % of the earth surface. What about data for ocean temperature and marine animals???🤔

[@teenee4]

You know from reincarnation research, everything is recorded. All optical observations through eyes 👀 and thoughts are recorded and can be played back as it happen, not probabilities but actualities. With no hardware needed. How? I'm glad you asked. ☺️
