Pan-Starrs : 6,000 deg2 per night. several terabytes per night for the full
telescope.hundreds of Peta bytes.
Software techniques are therefore being developed to extract the
information In full survey mode, typical exposures last 30 seconds, so the raw data rate is several terabytes per night for the full telescope. http://pan-starrs.ifa.hawaii.edu/public/design-features/data-handling.html

• GAIA
Gaia is a global space astrometry mission. Its goal is to make the largest, most precise three-dimensional map of our Galaxy by surveying an unprecedented number of stars - more than a thousand million.
