Gals and pals,

I recently read a proposal for using cloud services to filter through the accumulated data of SETI from the past 40 years.

What I wasn't able to find is how much data they have on their tapes, disk drives, and other media.

An aside, how much raw data does NASA, and other organizations, have saved up from their various astronomical projects throughout the years?

Thank you

As of last month, this piece (http://www.nasa.gov/mission_pages/hubble/story/) says that the Hubble Space Telescope alone has generated an archive of over 100 Terabytes. Archiving capabilities and practices vary widely (http://astronomy.ua.edu/keel/techniques/archives.html), being best for space missions and spottier for many ground-based optical observatories. The new ALMA observatory and upcoming LSST will each far exceed all the existing astronomical data volumes.
