ESA Data Archives
At Matera station are still stored:
~ ERS1 and ERS 2 HDDT tapes
~ LANDSAT, MOS and JERS HDDT
~ DLT, NTP, Exabyte tapes (ENVISAT, ERS, ….)
In Fucino Station there are:
~ ERS1 and ERS 2 HDDT tapes
All these tapes will be disposed in next months according to ESA Phase-Out activities

7. Data preservation activities
Part of the activites done on ESA contracts (during year ) have been:
re-ingestion of several thousands of LANDSAT data (since Landasat-3 to Landsat-7) stored on HDDTs support
the re-ingestion of about ERS1 LBR data stored on HDDT tapes.
The activities have been done using Schlumberger and Penny&Giles SE900 systems.
The Penny&Giles systems are still operative at Matera Station and have been recently used for the re-ingestion of further 500 ERS1/2 HDDT tapes on ESA request to fill some gaps in thier own data archive.
