Back when 10TB was enough space for the entire Sloan survey, Vera Rubin Observatory was expected to produce 1TB every night. They dug a trench up into the mountains to lay a fiber optic cable specifically (and only) for Vera Rubin.
- OldGuyInTheClub 3y agoNot to quibble but it is an even more mindboggling 15TB/night. https://www.ipac.caltech.edu/project/rubin https://www.ipac.caltech.edu/project/rubin
- dakr 3y agoHaha, it must be inflation. Back when I was involved the 1TB number was the one being thrown around. Thanks for posting that link. IPAC is really doing well for themselves with all the new projects they're hosting.
- OldGuyInTheClub 3y agoThat must be it! A few years ago, an old high school chum who works on the Rubin also mentioned the 15TB number. I neglected to ask if that was raw FPA output that would be processed down to smaller sizes or sent as-is. The project has been going for a while so maybe the technology to do it became practical in the interim? Whatever they do send, it is still an astronomical amount of data. I'll show myself out.
- ahazred8ta 3y agoLsst.org is now saying 20TB, or ~ 60 Petabytes for the whole run.
